Building a Damages Case: A Practical Guide from Pleading to Verdict

Summary. This guide runs a damages case in order, from the first client interview to the day the money arrives: the intake most lawyers skip, the hold that preserves the proof, pleading that protects consequential losses, discovery that builds a but-for world, controlling an expert, motions to exclude, settlement valuation, trial presentation, a verdict form that protects the award, and post-trial work on interest, costs, and collection.

Damages is the part of a case that rewards early work and punishes late work more sharply than any other. Liability facts are largely fixed by the time you are retained — the thing either happened or it did not. Damages proof, by contrast, is something you build, and almost every serious weakness in a damages presentation can be traced back to a decision made, or not made, in the first ninety days.

For the doctrine behind these steps, see Proving Damages in Civil Litigation. This guide is the operational sequence.

Stage 1: The damages intake

Most intakes are liability intakes. The client tells the story of what went wrong, and the lawyer takes notes on breach and causation. Do that, and then run a second interview that is only about money.

Ask these questions and write down the answers:

What did this cost you, in dollars, so far?
What is it going to cost you going forward, and for how long?
What did you have to spend because of the problem that you would not have spent otherwise?
What did you stop having to spend?
What did you do to limit the damage? What did it cost? Why did you choose that option?
What documents show any of this? Where do they live? Who controls them?
Who else saw the effect on you or your business?
What did the other side know about how this would hurt you, and when did they learn it?

That last question is the Hadley question and it belongs in the first interview, because the answer usually lives in emails that get deleted in month four.

Then ask for the "before" documents immediately: three years of tax returns and financial statements for a business claim; pay stubs, W-2s, and a job description for an employment claim; medical records for the two years preceding the injury for a personal injury claim. A damages case is a comparison. Half the comparison is the past, and the past is not going to get easier to reconstruct.

Finally, size the case honestly, out loud. If the realistic damages number will not support the cost of proving it, say so now. A $180,000 claim that needs a $70,000 expert and two years of litigation is a case to settle early, mediate, or decline — not a case to discover the arithmetic of in month twenty.

Stage 2: Preservation

Send the litigation hold before you do anything else, and make it specific to damages, not just liability.

What a damages-focused hold covers: accounting system data (including the ability to run historical reports), the general ledger, job costing records, CRM and pipeline data, inventory systems, payroll, purchase orders, invoices, quotes, communications with the customers or suppliers affected, backup tapes and cloud archives, and — often overlooked — the software licenses and personnel needed to read legacy data. A company that migrates ERP systems mid-litigation and loses the ability to query 2023 job costs has destroyed its own damages case.

On the defense side, the hold matters just as much: if the plaintiff's damages depend on your client's sales data, profits, or net worth, that data is now evidence.

Consider whether to preserve a snapshot of key systems at the outset. Reconstructing a dataset three years later, after two upgrades and a chart-of-accounts change, is expensive and produces a witness who has to explain discrepancies rather than results.

Stage 3: Pleading damages

Plead the categories, plead the facts that support the harder categories, and check two local rules.

Categories to plead expressly: general damages, special damages, consequential damages, incidental damages, statutory damages (identify the statute), attorney's fees (identify the contractual or statutory basis), prejudgment and post-judgment interest, costs, and punitive or exemplary damages where the facts support the required state of mind.

Special damages must often be pleaded with specificity. Federal Rule of Civil Procedure 9(g) requires that items of special damage be "specifically stated," and many state rules mirror it. A general prayer for "damages in an amount to be proved at trial" can, in some courts, forfeit categories never identified.

Plead the foreseeability facts. If you want consequential damages, allege what the defendant was told and when: the email describing the production schedule, the meeting where the deadline's significance was explained, the contract recital identifying the purpose. Foreseeability is a fact you prove, and pleading it early makes it a discovery subject rather than an afterthought.

Check two local rules. First, whether your jurisdiction prohibits stating a specific dollar amount in the prayer (many do, especially for personal injury and medical malpractice). Second, whether punitive damages require leave of court, a pre-suit notice, or a threshold evidentiary showing before the claim may be pleaded — several states impose one of these.

On the defense side, plead the damages affirmative defenses: failure to mitigate, setoff, collateral source where the state permits it, contractual limitation of liability, waiver of consequential damages, statutory cap, and comparative fault.

Stage 4: Write the damages theory memo

Before discovery opens, write two pages for the file — not for the client, not for the court:

The measure. Which legal measure applies to each claim, with a citation.
The formula. The actual arithmetic, with placeholders for the inputs you do not yet have.
The inputs. For each placeholder: what document or witness supplies it, and who has it.
The but-for world. How you will show what would have happened absent the wrong, and what evidence supports it.
The alternative causes. Every other explanation for the plaintiff's decline, and how the model addresses each.
The weakest link. Name it. It is almost always either the baseline, the causal isolation, or the discount rate.

This memo drives the discovery plan. Without it, discovery collects documents rather than answers.

Stage 5: Written discovery aimed at damages

Requests for production — plaintiff-side, seeking the defendant's data:

Financial statements, tax returns, and general ledgers for the relevant period.
Sales data by customer, product, and period, in native format with field definitions.
Profit-and-loss data at the level of the product line or business unit at issue.
Documents relating to the defendant's own projections and budgets for the relevant period.
Communications with the customers or suppliers the plaintiff claims to have lost.
For punitive damages: net worth and financial condition — subject to the timing rules, which in many states defer this discovery until a threshold showing is made.

Requests for production — defense-side, testing the plaintiff's claim:

Financial statements, tax returns, and ledgers for at least three years pre-breach.
All budgets, forecasts, and projections prepared before the dispute, and to whom they were given.
Documents relating to any other cause of the plaintiff's decline: lost customers, personnel departures, competitive entry, regulatory action, financing difficulty, product problems.
Every document relating to mitigation efforts, and communications refusing or declining alternative opportunities.
Loan applications and submissions to lenders or investors — these frequently contain optimistic projections that contradict the litigation narrative, or pessimistic ones that predate the breach.
Insurance policies and claims relating to the same loss.

A note on native format. Ask for accounting data as data, not as PDFs. A 900-page PDF of a general ledger is a discovery response designed to be useless. Specify the export format, the fields, and the date range in the request, and raise it at the Rule 26(f) conference so it lands in the scheduling order.

Interrogatories should force an itemization: "Separately state each category of damages you claim, the amount claimed for each, the method of calculation, and each document supporting it." Serve it early. Supplementation obligations then work for you all the way to trial.

Stage 6: Depositions

Take the operator, not just the executive. The controller who books the revenue, the plant manager who knows what the line actually costs to run, and the account manager who dealt with the lost customer are worth more than the CEO on damages.

Depose the lost customers themselves. A third-party customer who testifies she left because of the defendant's conduct converts an inference into a fact. A customer who testifies she left because of price, or service, or a relocation, destroys a damages theory — which is why the defense should take these depositions too, and why the plaintiff should take them first.

Questions that earn their time:

Which costs would have increased if the lost volume had been produced? Which would not?
What were the company's own projections at the time, and who prepared them?
What else changed in the business during the period?
Who decided to stop buying, and why? Was there a document?
What did you communicate to the other side about the consequences of a failure to perform?

Lock down the mitigation record with a deposition on what the plaintiff did, when, and what alternatives it considered and rejected. Ambiguity here is worth money at trial.

Stage 7: Selecting and retaining the expert

Retain early — before the close of fact discovery, ideally before written discovery is served. The expert should tell you what data she needs so you can request it. This is the single most valuable thing an early retention buys.

Choose for testimony, not just credentials. Read two prior reports and, if available, a transcript. Look for whether the expert can explain a method in plain language. A brilliant model presented by someone who cannot say what a discount rate is without a slide is a liability.

Vet exclusion history. Search for prior Daubert rulings. An expert excluded twice on methodology is a motion waiting to be filed against you.

Consider a consulting expert first where the numbers are uncertain. A consulting expert's work is generally protected as work product, which lets you find out whether the case is worth what the client thinks before you commit to a testifying opinion.

Control the engagement. Set the scope in writing. Do not send the expert a narrative of the case; send documents. And be aware of the 2010 amendments to Rule 26, which protect draft reports and most attorney-expert communications — but not the facts or data you provided, the assumptions you asked the expert to adopt, or compensation.

Stage 8: The report

Under Rule 26(a)(2)(B) the report must contain a complete statement of all opinions and the basis and reasons for them, the facts or data considered, exhibits, qualifications and publications from the last ten years, prior testimony from the last four years, and compensation.

Read the report as your opponent will. Specifically:

Is every input sourced? Every number should trace to a Bates-numbered document or to sworn testimony. "Per management" is a target.
Does the model isolate the conduct at issue? After Comcast Corp. v. Behrend, 569 U.S. 27 (2013), a model that measures harm from conduct no longer in the case is subject to exclusion.
Are alternative causes addressed affirmatively? Silence reads as an assumption.
Are the assumptions labeled as assumptions, with the source of each?
Is the arithmetic checkable by a person with a calculator and the exhibits?
Are the opinions stated completely? An opinion the expert intends to offer at trial but did not write down is an opinion likely to be struck.

Sensitivity analysis is worth including. Showing what the number becomes at a 9%, 11%, and 13% discount rate signals rigor and takes away the cross-examination that a single unexplained rate invites.

Stage 9: Rebuttal and motions to exclude

Rebuttal reports should do three things: identify errors in the opposing model, quantify their effect, and — where the strategy allows — present an alternative calculation. A rebuttal that only criticizes leaves the jury with one number on the board.

Bringing a motion to exclude. The standard is Rule 702 as amended, under which the proponent must show by a preponderance that the opinion rests on sufficient facts, uses reliable methods, and reliably applies those methods. Daubert supplies the gatekeeping frame, Kumho Tire extends it to financial and technical experts, and Joiner gives you the analytical gap argument.

Frame the motion around fit and application, not credentials. The winning motions say: the expert's method may be fine in general, but here she (a) applied it to data that does not support it, (b) measured something other than the harm alleged, or (c) assumed the very causation the plaintiff must prove.

Defending against exclusion. The best defense was built in Stage 8. Failing that: emphasize that the challenges go to weight, offer to narrow the opinion rather than lose it, and where the court signals concern, ask for leave to supplement rather than face a wholesale strike.

Stage 10: Summary judgment on damages

A damages-only summary judgment motion is underused. It assumes liability and argues that the plaintiff cannot prove the fact of injury or a non-speculative amount. If it succeeds only in part — knocking out lost profits and leaving reliance damages — it has still reframed the settlement conversation by an order of magnitude.

On the plaintiff's side, resist by separating the two halves of the certainty rule: the fact of damage is established by documents and testimony; the amount need only permit a just and reasonable estimate. The Supreme Court's language in Bigelow v. RKO Radio Pictures, 327 U.S. 251 (1946) and Story Parchment Co. v. Paterson Parchment Paper Co., 282 U.S. 555 (1931) — that a wrongdoer may not profit from the uncertainty its own conduct created — is the paragraph to quote.

Stage 11: Valuing the case for settlement

Build a decision tree, not a number:

P(liability) × P(damages survive exclusion) × expected award, less fees and costs, discounted for time and collection risk.
Run it at three award levels: the model, half the model, and the fallback measure.
Add the value of any fee-shifting exposure — on both sides.
Subtract the cost to get to verdict, honestly stated.

Two adjustments people forget. First, collectibility: a $4 million verdict against an entity with $600,000 in assets and no insurance is a $600,000 case. Investigate assets and coverage early. Second, the cost of the damages case itself — expert fees, data extraction, and the motion practice — which in commercial cases routinely exceeds the cost of the liability case.

In mediation, bring the damages exhibits, not the report. Mediators move money when they can see the arithmetic in ninety seconds.

Stage 12: Trial presentation

Give the jury a number early. In opening, tell them what you will ask for and why. Jurors who hear a number for the first time in closing distrust it.

Build the case in exhibits, not testimony. One demonstrative per component: the baseline, the but-for revenue, the avoided costs, the mitigation credit, the total. Numbers on a board, in order, with a running total.

Have the expert teach, not testify. The best damages examinations begin with the method in plain English before any number appears: "Before we get to the calculation, explain how an economist figures out what would have happened if something hadn't happened."

Anticipate the cross in direct. Bring out the assumptions, the sensitivity range, the mitigation credit, and the fee the expert is being paid. Every one of those is a cross-examination point that loses its force when the jury hears it from you first.

For non-economic damages, resist the temptation to argue and instead accumulate specific, ordinary detail from witnesses with no stake in the outcome. Know whether your jurisdiction permits a per-diem argument before you plan one, and never invite the jury to place itself in the plaintiff's position — the golden rule objection is sustained nearly everywhere.

Stage 13: Instructions and the verdict form

Draft both early, because they tell you what the proof must establish.

Instructions to fight for: the reasonable certainty instruction that distinguishes the fact of damage from the amount; the wrongdoer-uncertainty instruction; the burden on mitigation resting with the defendant; and, where punitive damages are in play, the Philip Morris v. Williams instruction permitting harm to nonparties to be considered on reprehensibility while forbidding punishment for it.

Verdict form design:

Itemize by category — past economic, future economic, past non-economic, future non-economic, consequential, statutory.
Add interrogatories on the disputed inputs where the categories will be attacked post-trial.
For punitive damages, use a bifurcated form and confirm whether your jurisdiction requires a separate proceeding.
Include a line for comparative fault percentages if applicable, and know whether the court or the jury applies the reduction.

A general verdict with one blank is a trap for whoever wins: it cannot be defended in detail on appeal, and it cannot be attacked in detail either.

Stage 14: After the verdict

Post-trial motions. Expect a motion for new trial or remittitur arguing the award is excessive or unsupported. Your itemized verdict form and your exhibits are the answer. On the defense side, a remittitur motion should tie the excess to a specific category and a specific evidentiary gap, not to the size of the number.

Punitive damages review. If a punitive award is entered, expect de novo constitutional review under BMW of North America v. Gore and State Farm v. Campbell. Preserve the reprehensibility record — duration of the conduct, concealment, vulnerability of the victim, repetition — because the ratio argument is only as good as the reprehensibility showing beneath it.

Interest. Move for prejudgment interest promptly, and compute it correctly: the rate, the accrual date for each component, and whether it is simple or compound are all state-law questions worth real money. Post-judgment interest accrues by statute from entry of judgment.

Costs. File the bill of costs within the deadline — often 14 days — under Rule 54(d) and 28 U.S.C. § 1920. Expert fees are generally not taxable as costs absent a fee-shifting statute, which surprises people every year.

Fees. If a statute or contract shifts fees, the petition is its own project. See Preparing and Opposing a Fee Petition.

Stage 15: Collecting

A judgment is a piece of paper. Convert it.

Abstract and record the judgment to create liens; docket it in every county and state where the debtor has property; serve post-judgment discovery immediately (many defendants' assets move within weeks of a verdict); then garnish accounts and wages, levy on personal property, and use the charging order remedy against partnership and LLC interests. Watch for fraudulent transfers made in the months before or after verdict — the uniform act gives you a claim and a longer reach than most defendants expect.

Where collection is doubtful, the time to have learned that was Stage 11.

Stage 16: Damages in special postures

The fifteen stages assume a two-party civil case tried to a jury. Four common postures change the sequence.

Class actions. Damages is where class certification is usually won or lost. Rule 23(b)(3) predominance requires that common questions predominate, and after Comcast Corp. v. Behrend, 569 U.S. 27 (2013) the damages model must be capable of measurement on a classwide basis and tied to the theory of liability certified. Practical consequences: build the classwide model before moving for certification, not after; expect a full motion to exclude at the certification stage; and consider whether individualized damages can be handled by a claims process, a formula, or bifurcation without defeating predominance. Statutory damages claims are attractive here precisely because they remove individualized proof — but watch the aggregation and due process arguments defendants raise when the classwide statutory figure becomes astronomical.

Arbitration. Discovery is limited, so the damages record must be built from documents you can get without a subpoena power you may not have. Check the rules for whether the arbitrator may award punitive damages, consequential damages excluded by the contract, or attorney's fees. Many commercial arbitration clauses limit remedies, and an award exceeding the contractual limit is one of the narrow grounds on which a court may disturb it. Present damages to an arbitrator the way you would to a judge in a bench trial: a written submission with the arithmetic laid out, exhibits tabbed, and a summary schedule on one page.

Bankruptcy. If the defendant files, your damages claim becomes a proof of claim subject to allowance under § 502, and unliquidated claims may be estimated by the court. Preserve the claim by filing on time, watch for the automatic stay's effect on pending litigation, and consider whether any part of the claim is nondischargeable — fraud, willful and malicious injury, and fiduciary defalcation each have their own subsection, and the deadline to file that adversary proceeding is short and unforgiving.

Insurance-funded defense. Where a liability insurer is defending, the damages presentation has an audience the jury never sees: the adjuster and coverage counsel evaluating exposure against policy limits. A well-documented demand within limits, made early and supported by the damages exhibits, creates the record for a later bad-faith claim if the insurer refuses and an excess verdict follows. Send it certified, give a reasonable deadline, and keep it open long enough to be reasonable.

A worked sequence: one case, sixteen stages

The case. Delta Fabrication, a 40-employee metal shop, sues an equipment vendor over a CNC machine that never met its stated cycle time. Purchase price $780,000. Delta says it lost three years of production capacity.

Stage 1. The intake produces the essential fact: Delta turned down a $2.1 million contract from an aerospace supplier because the machine could not hold tolerance. That is the fact of damage, and it is documented in a declination email. Everything else in the case is arithmetic.

Stage 2. The hold captures the ERP job-cost data, the machine's controller logs, the maintenance tickets, and the correspondence with the aerospace supplier — plus a snapshot of the ERP database before a scheduled upgrade six weeks later.

Stage 3. The complaint pleads breach of warranty, breach of contract, and fraud in the inducement; itemizes special damages under Rule 9(g); and alleges specifically that Delta told the vendor's sales engineer, in a March 2023 meeting, that the machine was being purchased to serve aerospace tolerances. That allegation is the foreseeability predicate for consequential damages, and the vendor's own meeting notes later confirm it.

Stage 4. The theory memo picks expectation damages measured as lost incremental profit on the declined contract plus the cost of the workaround Delta adopted, with reliance damages as the fallback. Weakest link identified: whether the aerospace contract would actually have been awarded to Delta.

Stage 5–6. Discovery targets the aerospace supplier directly. Its sourcing manager testifies Delta was the selected vendor pending a capability demonstration. That deposition converts a speculative opportunity into a probable one — and it happens in month nine, not month twenty.

Stage 7–8. A manufacturing economist is retained in month four and asks for machine utilization data nobody had thought to request. The report ties every input to production records, credits the profit Delta earned on the substitute work it took instead, and runs the model at three discount rates.

Stage 9–10. The vendor moves to exclude on the ground that the aerospace contract was speculative. The motion fails because the sourcing manager's testimony, not the expert's assumption, supplies the probability. The vendor's own damages-only summary judgment motion is denied for the same reason.

Stage 11–13. Mediation at $1.4 million fails. At trial the number goes into opening. The verdict form itemizes the declined-contract profit, the workaround cost, and the purchase price refund separately.

Stage 14–15. The jury itemizes. The post-trial remittitur motion cannot dislodge the workaround cost, which rests on invoices. Prejudgment interest adds nine percent of the total. The vendor is solvent and insured, and the judgment is satisfied in four months.

The thing that made this case was not the expert. It was the declination email, found in Stage 1, and the sourcing manager's deposition, taken because Stage 4 identified the weakest link and Stage 5 went after it.

For non-lawyers: the part you can do yourself

You cannot run a Daubert motion. You can do the four things that most often decide whether a damages case is worth anything.

Build the "before" file. Tax returns, financial statements, pay stubs, invoices, bank statements, medical records — three years back, before anything went wrong. Get them now, while they are easy to obtain.
Keep a contemporaneous record of the harm. A dated log with what happened, what it cost, and who you spoke to. Write it the week it happens. It will be more persuasive than anything you can reconstruct later, and it is admissible in ways a later summary is not.
Preserve everything, including devices. Do not delete texts, do not wipe a phone, do not let a software subscription lapse if your records live inside it. Deleting relevant material after a dispute arises can cost you the case on its own, independent of the merits.
Mitigate, and document the mitigation. Take reasonable steps to limit the loss and keep the receipts. If you decline an option, write down why at the time. "I turned down the replacement job because it required relocating my family" is a good answer given contemporaneously and a weak one invented at deposition.

And one thing not to do: do not inflate. A single provable exaggeration — an invoice for work never performed, a claimed injury contradicted by a social media post, a projection nobody ever believed — will be the only thing the jury remembers about your numbers.

The defense playbook, in the same order

Everything above is written from the plaintiff's chair. The defense runs the same sequence in reverse, and runs it earlier than most defendants expect.

At intake. Value the exposure before you value the liability defense. Ask the client the same damages questions the plaintiff's lawyer asked: what did this plausibly cost them, what documents show it, and what else was going on in their business at the time. Then find out what insurance responds and tender promptly. A late tender is a coverage fight you did not need.

Preservation. Your client's sales data, profit records, and — if punitive damages are pleaded — net worth are now evidence. So are the communications in which anyone at the company discussed the plaintiff's likely losses. Hold them.

Pleading. Plead every damages affirmative defense you might use: failure to mitigate, setoff, contractual limitation of liability, waiver of consequential damages, statutory cap, comparative fault, collateral source where allowed, and any notice or presentment condition the plaintiff skipped. Defenses not pleaded are often waived, and a limitation-of-liability clause raised for the first time at the pretrial conference is a clause you may not get to use.

Discovery. Build the alternative-cause file from the plaintiff's own documents: the customer who left before the breach, the credit line that was pulled, the two salespeople who quit, the recall, the competitor that opened four miles away. Get the plaintiff's pre-dispute projections — the ones given to a bank or a board — because they were prepared when nobody was thinking about a lawsuit. And serve the itemization interrogatory early so the plaintiff is locked into a theory you can attack.

Depositions. Take the lost customers. A third-party customer who gives a reason other than your client's conduct removes an entire component of the model. Take the controller on cost behavior, because the fixed-versus-variable allocation is where the biggest arithmetic errors live.

Experts. Decide early between a rebuttal-only expert who attacks the plaintiff's model and an affirmative expert who offers a competing number. Rebuttal-only preserves the "plaintiff failed to prove damages" argument in its pure form; an affirmative number risks conceding that damages exist but gives the jury an alternative to anchor on. In a case you expect to lose on liability, the alternative number is usually worth more than the purity.

Motions. File the damages-only summary judgment motion. Even a partial win — eliminating lost profits and leaving reliance — resets the case's value. Pair it with the motion to exclude, and file them together so the court sees that without the expert there is no evidence of amount at all.

Trial and after. Cross the expert on inputs, not credentials. Ask for an itemized verdict form, because it gives you specific targets for remittitur. And preserve the punitive damages objections — the reprehensibility instruction, the nonparty-harm limitation from Philip Morris, and the ratio — at every stage, because constitutional review is available only on a preserved record.

Five mistakes that cost real money

Waiting on the expert. The most expensive decision in commercial litigation is retaining the damages expert after fact discovery closes. She then builds a model out of whatever happens to have been produced, rather than out of what she needed. Every subsequent problem — unsourced inputs, unaddressed alternative causes, a baseline drawn from the wrong period — traces back to that one delay.

Modeling the plaintiff instead of the claim. A model that measures a firm's overall revenue decline invites the defense to explain the decline with everything else that happened to the firm. A model that measures the specific contract, product line, or customer relationship at issue makes most of that evidence irrelevant. Narrow the model and you narrow the fight.

Treating fixed costs as avoided. Subtracting an allocated share of rent, depreciation, and management salaries from lost revenue can cut a damages number by a third, and it is wrong whenever those costs continued unchanged. The financial statements prove it either way, so the expert should address it affirmatively rather than leave it to cross-examination.

Ignoring collectibility. Investigate assets, insurance, and corporate structure in the first month. Discovering in month twenty-two that the defendant is a single-purpose entity with a lapsed policy converts two years of work into a lesson. On the defense side, the mirror error is failing to tender to every potentially responsive carrier.

Losing the record for post-trial review. Preserve objections, request the itemized verdict form, and get your instructions on the record. Appellate courts review what was preserved, and a large verdict defended on a general form is harder to keep than one defended on a form that shows exactly what the jury found and why.

Frequently asked questions

How early should I retain the damages expert? Before written discovery closes, and ideally before it is served. The expert tells you what to ask for.

Can I amend my damages theory after the expert report? Sometimes, with leave and a showing of good cause, but expect a fight and possibly exclusion. Design the theory in Stage 4.

What if my client's records are a mess? Reconstruct from third-party sources: bank statements, customer invoices, tax returns, supplier records. Then say so plainly. Juries forgive imperfect records; they do not forgive numbers that appear from nowhere.

Should I put a number in my opening? Almost always yes. The exception is where local practice or a specific judge disfavors it.

Do I need an expert for a straightforward contract case? Often not. Business records, a summary exhibit, and an owner or controller who can do the arithmetic on the stand will carry many commercial cases without a retained expert.
