Before you wire a dollar, verify client contracts, retainer quality, talent retention risk, and platform dependencies with this deal-tested framework.
Acquiring an e-commerce agency in the $1M–$5M revenue range offers access to recurring retainer cash flow, established DTC client relationships, and platform certifications that take years to build. But the value of these businesses is fragile — concentrated in a handful of client relationships, dependent on key team members, and exposed to algorithm changes on Google, Meta, and Amazon that can erode performance overnight. This checklist walks buyers through five critical due diligence categories specific to e-commerce agencies: revenue quality, client contract integrity, talent and culture risk, technology and platform dependency, and financial margin analysis. Work through every item before submitting a final LOI or proceeding to close.
Verify the true composition of revenue — separating durable retainer income from one-time project work — and assess client churn trends over the past three years.
Request a monthly revenue schedule for 36 months segmented by client and revenue type.
Reveals true retainer percentage and exposes revenue volatility hidden in annual totals.
Red flag: More than 30% of trailing revenue is project-based or one-time in nature.
Calculate net revenue retention rate by cohort for each of the past three years.
NRR above 100% signals upselling and sticky client relationships worth a premium.
Red flag: NRR below 85% indicates chronic churn that will compress post-close earnings.
Identify all clients who churned in the past 24 months and document the stated reason.
Churn patterns reveal platform performance issues, pricing problems, or founder dependency.
Red flag: Multiple clients citing underperformance or poor communication as exit reasons.
Confirm average client tenure in months across the current active client roster.
Tenure above 24 months supports valuation multiples and reduces post-close revenue risk.
Red flag: Average client tenure under 18 months signals weak retention and fragile retainer base.
Assess the legal durability of client relationships, termination rights, and revenue concentration risk across the active client book.
Obtain and review all active client contracts, including termination notice periods and auto-renewal terms.
Short notice periods allow clients to exit quickly after ownership change is announced.
Red flag: Month-to-month contracts with 30-day termination clauses representing over 40% of revenue.
Calculate revenue concentration: identify each client's share of total trailing twelve-month revenue.
No single client should exceed 20% of revenue to avoid catastrophic post-close churn.
Red flag: Top client exceeds 25% of revenue with no long-term contract in place.
Verify whether client contracts include change-of-control clauses that trigger renegotiation or termination.
Change-of-control provisions can allow clients to exit immediately upon acquisition close.
Red flag: Two or more top-five clients have enforceable change-of-control termination rights.
Review scope-of-work definitions and billing arrangements for scope creep or unbilled overages.
Unbilled scope creep inflates apparent revenue quality and compresses true margin.
Red flag: Significant hours delivered above contracted scope with no corresponding billing or amendment.
Evaluate the degree to which the business depends on the founder or a small group of employees, and assess the risk of talent departure post-close.
Map all client relationships to identify which team member manages each account day-to-day.
Founder-managed relationships are the single greatest post-acquisition revenue risk in agency deals.
Red flag: Founder is the primary contact for clients representing over 50% of revenue.
Review all employee agreements for non-solicitation, non-compete, and confidentiality provisions.
Without enforceable agreements, key team members can leave and take clients post-close.
Red flag: Senior account managers or strategists have no non-solicitation agreements in place.
Interview the three to five most senior non-founder employees to assess retention intent and cultural alignment.
Team departure post-close can collapse service quality and trigger client churn simultaneously.
Red flag: Key employees express uncertainty about staying or are unaware of the pending transaction.
Assess current compensation benchmarking and identify below-market salaries that create flight risk.
Underpaid talent is a retention liability that will require immediate post-close salary correction.
Red flag: Senior team members are compensated 20%+ below market rates for their platform specializations.
Examine the agency's reliance on third-party platforms, software subscriptions, and certification statuses that underpin its service delivery and client value proposition.
Verify all active platform certifications including Google Premier Partner, Meta Business Partner, and Amazon Ads accreditation.
Certifications are transferable only under specific conditions and may lapse post-acquisition.
Red flag: Certifications are held personally by the founder and cannot be transferred to the acquiring entity.
Inventory all software subscriptions and SaaS tools used in service delivery, including seat licenses and annual costs.
Hidden tool costs reduce true EBITDA and may include founder-specific licenses that lapse at close.
Red flag: Material tools are licensed to the founder personally with no business-entity transfer path.
Assess dependency on any single advertising platform for client performance and revenue generation.
Over-reliance on one platform creates existential risk if algorithm or policy changes occur.
Red flag: More than 70% of client campaigns depend exclusively on a single platform like Meta or Google.
Review any proprietary reporting dashboards, tracking infrastructure, or automation tools built in-house.
Proprietary tools create switching costs and competitive differentiation worth preserving post-close.
Red flag: No documentation exists for proprietary tools and only the founder knows how they function.
Verify reported EBITDA, assess margin quality by client and service line, and confirm the cleanliness of financials prepared for the transaction.
Obtain three years of accrual-based financial statements reviewed or compiled by an independent CPA.
Cash-basis books in agency transactions frequently misstate revenue timing and true profitability.
Red flag: Only tax returns or internally prepared spreadsheets are available with no CPA involvement.
Perform a quality of earnings analysis to recast EBITDA by removing owner perks, personal expenses, and one-time items.
Normalized EBITDA is the foundation of valuation and SBA loan sizing for this acquisition.
Red flag: Owner add-backs exceed 25% of stated EBITDA or include items difficult to verify independently.
Analyze gross margin by client account and service line to identify unprofitable or subsidized relationships.
Agency margins vary widely by client; unprofitable accounts masked in blended numbers destroy post-close returns.
Red flag: One or more top-five clients have gross margins below 30% due to scope creep or underpricing.
Review contractor and freelancer spend trends over 36 months to assess labor cost scalability.
Heavy reliance on contractors can signal a fragile delivery model or misclassified employee relationships.
Red flag: Contractor spend has grown faster than revenue for two consecutive years without a clear rationale.

Vetted targets with diligence packages — skip the cold search.
E-commerce agencies in the $1M–$5M revenue range typically trade at 3x to 5.5x EBITDA. The higher end of that range is justified when the agency has 70%+ retainer revenue, no single client exceeding 15–20% of revenue, documented SOPs, platform certifications, and a management team that operates independently of the founder. Agencies with high founder dependency, short client tenures, or heavy project revenue will price closer to 3x or lower. Always anchor your offer to normalized, recast EBITDA — not the seller's stated number.
Request a 36-month monthly revenue schedule broken out by client and contract type. Identify which revenue is governed by signed retainer agreements with defined notice periods versus informal rolling arrangements. Calculate net revenue retention by cohort to see whether existing clients are growing, staying flat, or churning. True recurring revenue comes with contracts, predictable monthly billing, and average client tenures exceeding 24 months. Anything less should be recharacterized as semi-recurring or variable in your underwriting model.
Yes. E-commerce agencies are generally SBA-eligible businesses, and SBA 7(a) loans are a common financing structure for acquisitions in this sector at the lower middle market level. A typical SBA-financed deal requires 10–15% equity injection from the buyer, with the balance financed through the SBA loan up to $5M. Sellers often contribute a seller note of 5–10% on standby to complete the capital stack. SBA lenders will scrutinize revenue quality heavily — agencies with strong retainer contracts and clean financials will underwrite significantly better than project-heavy shops with volatile cash flow.
This is the most critical risk in any e-commerce agency acquisition. Clients often have personal relationships with the founding operator, and a change in ownership — if handled poorly — can trigger early termination or non-renewal. Mitigate this by structuring a meaningful seller transition period of 12–24 months, introducing the buyer to clients before close, and ensuring the seller communicates the transition as a positive upgrade rather than an exit. Earnout structures tied to client retention over 18–24 months post-close align the seller's incentives with client stability and reduce your downside exposure significantly.
