E-commerce Expert Witnesses

Litigation involving e-commerce increasingly centers on the technology and contractual infrastructure that keeps online commerce running rather than on the underlying transactions themselves. Disputes arise when a marketplace suspends a seller's account without apparent cause, when a fulfillment or payment-processing vendor fails to meet the service levels its contract promised, or when a platform migration or pricing-engine defect disrupts a retailer's highest-volume selling period. Attorneys also see claims tied to digital advertising fraud, data breaches attributed to a vendor's cybersecurity lapses, and competitors accused of misappropriating proprietary checkout or search-ranking technology. Because these disputes often turn on whether a platform, vendor, or algorithm performed as represented, the central issue is typically one of technical compliance and causation rather than simple consumer harm.

Expert analysis in these matters generally begins with the underlying system records — server logs, load-test results, incident reports, or code repositories — that reveal what actually happened during the disputed event. An e-commerce expert can assess whether a platform's enforcement or ranking decisions followed its own documented policies, whether a vendor's uptime or fulfillment performance met contractual service-level commitments, or whether a pricing or checkout system's defect traces to a specific engineering failure. This analysis supports causation and damages calculations, informs liability allocation between platform operators and their vendors, and can substantiate or rebut claims that lost revenue stemmed from a breach of contract rather than ordinary market forces. In IP-related disputes, the same technical review can identify whether a competitor's system reflects independent development or the use of misappropriated source code.

Selecting the right expert for an e-commerce dispute requires matching the assignment to genuinely relevant technical experience, since the same case can call for a systems architect, a marketing and consumer-behavior specialist, or a network security professional depending on what is actually in dispute. Round Table Group's e-commerce network includes practitioners with decades of experience in internet commerce, user interface design, and systems architecture, including backgrounds built at organizations such as Apple and the University of Chicago, alongside specialists in information technology, management information systems, and network security who have advised on e-government and online sales infrastructure. We have completed more than 75,000 expert searches for litigators, giving us a practiced sense of which technical backgrounds hold up under deposition and cross-examination in fast-moving commercial technology disputes.

Kinds of Cases We Work On

Round Table Group helps our clients find a wide variety of E-commerce expert witnesses for cases like:

01

Online Marketplace Seller Suspension Dispute.

A large third-party seller sued a major online marketplace after its account was suspended without notice during peak shopping season, alleging the suspension breached the marketplace's seller agreement and cost the seller a significant share of its annual revenue. We identified experts with experience in e-commerce marketplace operations, seller policy enforcement standards, and platform trust-and-safety practices. The expert's review of the marketplace's enforcement records found the suspension deviated from its own documented escalation policy, supporting a substantial settlement.
02

Holiday Fulfillment SLA Breach Claim.

A national retailer sued its third-party logistics provider after missed delivery windows and warehouse mishandling during a holiday sales period caused widespread order cancellations, alleging breach of the fulfillment services agreement's service-level commitments. We identified experts with experience in e-commerce fulfillment operations, warehouse management systems, and logistics SLA performance analysis. The expert's analysis of the provider's own operational data confirmed performance had fallen well below the contracted service levels, supporting a substantial recovery.
03

E-commerce Platform Migration Failure Dispute.

An online retailer sued its e-commerce platform vendor after a botched replatforming project caused the retailer's site to crash repeatedly during its highest-volume sales weekend, alleging the vendor had misrepresented the platform's load-testing results. We identified experts with experience in e-commerce platform architecture, site scalability testing, and software implementation project management. The expert's review of the vendor's pre-launch load tests found they had never simulated realistic peak traffic, supporting a substantial settlement.
04

Payment Gateway Checkout Outage Dispute.

A mid-size online retailer sued its payment processor after a multi-hour checkout outage during a major promotional event caused a wave of abandoned carts and lost sales, alleging the outage breached the processor's uptime guarantee. We identified experts with experience in payment processing systems, e-commerce checkout architecture, and uptime SLA analysis. The expert's review of the processor's incident logs established the outage exceeded the contractual downtime threshold, supporting a meaningful settlement.
05

Digital Click Fraud Advertising Dispute.

An online retailer sued a digital advertising network, alleging that a significant share of the clicks it had paid for on a performance-marketing campaign originated from bot traffic rather than genuine consumers. We identified experts with experience in digital advertising fraud detection, web traffic analytics, and click-through attribution methodology. The expert's traffic-pattern analysis identified click volumes consistent with automated bot activity across a large share of the campaign, supporting a substantial recovery in arbitration.
06

Dynamic Pricing Algorithm Defect Dispute.

A retailer sued its pricing software vendor after a defect in the vendor's dynamic pricing engine caused thousands of products to be listed well below cost for several hours during a high-traffic sales event, alleging the resulting losses stemmed from the vendor's negligent software design. We identified experts with experience in e-commerce pricing algorithms, software quality assurance, and retail systems architecture. The expert's code review traced the defect to an unvalidated data feed the vendor had failed to test, supporting a substantial settlement.
07

Customer Data Breach Vendor Liability.

A retailer sued its cybersecurity vendor after a breach exposed customer payment data across its e-commerce platform, alleging the vendor had failed to detect a known vulnerability it was contractually engaged to monitor. We identified experts with experience in e-commerce cybersecurity, payment data security standards, and network intrusion forensics. The expert's forensic review found the vulnerability had been flagged in the vendor's own prior scan reports but never remediated, supporting an indemnification recovery of nearly $15 million.
08

One-Click Checkout Technology IP Dispute.

An e-commerce technology company sued a competitor, alleging its one-click checkout feature had been built using proprietary source code taken by a former engineer who joined the competitor. We identified experts with experience in e-commerce software architecture, source code forensics, and checkout system design. The expert's code comparison found substantial structural overlap between the two systems' checkout logic, supporting a favorable verdict at trial.
09

Marketplace Search Ranking Suppression Dispute.

A branded seller sued an online marketplace, alleging its product listings had been algorithmically demoted in search rankings shortly after the seller launched a competing storefront outside the marketplace, in violation of the platform's stated ranking policies. We identified experts with experience in e-commerce search ranking algorithms, marketplace policy compliance, and platform competition practices. The expert's analysis of ranking-signal data found no performance-based justification for the sudden drop, supporting a substantial settlement.
10

Subscription Billing Platform System Failure.

A subscription commerce company sued its billing platform vendor after a software update caused thousands of customer accounts to be billed incorrectly over several billing cycles, generating a wave of chargebacks and cancellations. We identified experts with experience in subscription billing systems, e-commerce revenue operations, and software change-management practices. The expert's review traced the errors to an untested update pushed without a rollback plan, supporting a substantial recovery in mediation.

Questions Attorneys Ask About E-commerce Expert Witnesses:

An e-commerce expert becomes valuable once a dispute turns on whether a platform, vendor, or system performed as contractually promised — for example, a marketplace suspension, a missed fulfillment SLA, or a checkout outage during a peak sales period. Counsel typically retains an expert once internal records point to a technical or operational failure that a lay factfinder cannot evaluate without guidance.
