Most agency founders think due diligence starts when the term sheet is signed. It doesn't. Due diligence starts the day the acquirer sends over their information request list, which is usually two to three weeks after the term sheet, and by that point every gap in your operational history — every misclassified expense, every unsigned contractor agreement, every undocumented IP transfer — is about to be discovered by a team of very careful strangers.
The agencies we've led through successful exits — Ray Enterprises (acquired by Amazon), Respire Medical (acquired by Whole You / Mitsui Chemicals), and Silverline (growth investment from Pamlico Capital) — all share one thing in common: they started preparing for diligence at least six months before the process began. That preparation is what a CAS partner refers to as pre-diligence, and it's the single highest-leverage thing an agency's leadership can do to improve deal outcomes.
Financial statements ready for a stranger's eyes
Your acquirer will not accept the version of your financials that lives in your head. They will want three years of monthly financial statements, prepared consistently, with a documented accounting policy manual behind them. If your chart of accounts has drifted over the years — new categories added, old ones repurposed, personal expenses accidentally mixed in — pre-diligence is when to fix that, not during diligence.
Checklist items:
Chart of accounts standardized and consistent across all three years
Monthly financial statements (income statement, balance sheet, cash flow) prepared under GAAP
Accrual accounting applied consistently — cash-basis financials will get rejected
Revenue recognition policy documented (especially for retainer, project, and multi-deliverable engagements)
Accounting manual describing how transactions are categorized and how the month is closed
Bank and credit card reconciliations complete through the most recent month
Contracts and client agreements — signed, current, and organized
Acquirers will ask for every client contract. If your top ten clients don't have signed master service agreements, or if the terms in the file don't match what's actually happening, that's a red flag. It's fixable in pre-diligence and painful during diligence.
Checklist items:
Master service agreements or engagement letters signed and on file for every active client
Contractor agreements signed and on file, with IP assignment language current
Employee agreements signed with clear IP and non-compete provisions where enforceable
Lease agreements current and organized
Vendor and software contracts inventoried, with auto-renew dates flagged
NDAs on file for anyone with access to material client or financial information
Intellectual property — trace it back to the source
For a creative agency, IP is the balance sheet even if it doesn't appear there. Acquirers want to know: what did you create, who owns it now, and can you prove the chain of assignment?
Checklist items:
IP register listing every material work product created for a client — with the underlying contract that transferred (or retained) ownership
Contractor IP assignments in force for anyone who touched client deliverables
Any proprietary tools, methodologies, or software your agency uses internally — documented, with clear ownership
Registered trademarks and copyrights (if any) up to date and in the company's name
Any prior IP disputes or claims documented with resolution
HR, compliance, and the tax posture
This is where acquirers find the sleeper issues. Multi-state payroll compliance for remote employees. Sales tax nexus in states where you have contractors. 1099 versus W-2 classifications that don't hold up. Benefits plans that quietly failed nondiscrimination testing.
Checklist items:
Payroll set up correctly in every state where you have workers (employees or contractors)
Sales tax nexus reviewed and, where triggered, registered and current
1099 vs W-2 classifications defensible under the applicable state's test
Employee handbook current and reflecting actual policy
Benefits plans reviewed (health, 401(k), ESOP if applicable) — nondiscrimination testing current
Any pending or historical employment claims documented
Federal and state income tax returns filed and current
Any prior audits or notices resolved and documented
Data room — pre-populated, not scrambled together
A good pre-diligence process ends with a data room that is 80% populated before diligence formally begins. When the acquirer sends their information request, most items are already there. This has two effects: it dramatically shortens the diligence timeline, and it signals to the acquirer that leadership runs a tight operation — which affects both valuation and the specific reps and warranties the acquirer will demand.
A well-organized data room typically contains: financials, contracts, IP register, HR files, tax records, insurance policies, cap table and equity documents, board consents and meeting minutes, litigation history (if any), key employee background information, and technology/systems documentation.
Where a CAS partner fits in
The checklist above is a lot of work, and most of it isn't the founder's zone of genius. It's why every one of the successful exits we've led at Black Ink involved us running the pre-diligence workstream on behalf of the agency's leadership — closing the accounting gaps, building the data room, coordinating with legal and tax advisors, and acting as the main point of contact once the acquirer's diligence team arrived.
The pattern we've seen consistently: agencies that engage a CAS partner six to twelve months before a transaction close close cleanly, on time, and at their asking valuation. Agencies that start pre-diligence work three weeks before diligence begins — usually don't.
If a transaction is on your horizon
Whether it's a growth investment, a strategic acquisition, or a founder liquidity event — pre-diligence is not the kind of work that can be scoped a month before it needs to be done. Start early.
If you're at that inflection point and want to talk about how pre-diligence should look for your specific agency, we'd be glad to hear from you. Black Ink Business Services has led the diligence workstream for exits at multiple scales, from consumer-electronics acquisitions to growth-equity investments in professional-services firms.
