Thinking about buying a startup or selling your own? In the world of mergers and acquisitions (M&A), especially for tech companies, the deal lives or dies in diligence.
We’ve seen fantastic products stumble at the finish line because the numbers didn’t back up the story or because basic records were messy. At ShayCPA, our job is to make sure your financials are crisp, your tax posture is understood, and your metrics hold up when a buyer (or their Quality of Earnings-QoE firm) pulls the thread.
Why Diligence Can Make or Break a Deal
Tech deals often move quickly, but diligence slows things down on purpose. Buyers want proof that your growth is durable and that cash flows behave the way your deck suggests. Sellers want to keep valuation intact and avoid last-minute re-trades. That only happens when data is complete, consistent, and easy to verify. Founders routinely underestimate this phase; dashboards and bank PDFs won’t cut it. Diligence is a window into how you run finance, not just what you report.
Even with shifting markets, strategic acquirers and roll-ups continue to shop for efficient growth, strong teams, and products that complement existing platforms. That dynamic makes process quality a competitive advantage. Clean books, standard KPIs, and tight tax work don’t just “pass” diligence; they shorten timelines and protect price.
A Common Mistake: Underestimating the Lift
A scattered data room, inconsistent exports, or unexplained variances signal risk. Buyers respond with larger escrows, tighter reps and warranties, or a lower number. Treat “diligence-ready” as a capability you build well before you run a process. The earlier you invest, the fewer surprises later.
Key Financial Documents Buyers Expect
Historical financials (monthly). Provide since inception or at least three years of:
- Income statement, balance sheet, cash flow statement, and trial balance
- Bank, AR/AP, and payroll reconciliations
- Cash vs. accrual view, with clear revenue recognition and deferred revenue treatment
Revenue detail & SaaS metrics. Expect to share:
- MRR/ARR by month with a bridge (new, expansion, contraction, churn)
- Gross and net dollar retention (GRR/NRR), logo churn, cohort behavior
- Revenue by product/plan/channel, contract term, and renewal cadence
- A deferred revenue roll-forward tying bookings → billings → GAAP revenue
Gross margin clarity
Break out hosting, third-party data, payment processing, support/success, and any pass-through costs. If support is in OpEx, disclose recasts so buyers can compare apples to apples.
OpEx and headcount
Include a headcount roll (titles, start dates, base/variable comp, contractors) and your capitalization policy for software and commissions. Inconsistent capitalization is a common adjustment.
Unit economics
Share your LTV/CAC framework, CAC payback, and attribution assumptions. Label your inputs, churn, discounting, and cohort window, so a QoE firm can replicate the math.
Forecasts and pipeline
Provide a bottom-up model driven by pricing, win rates, ramp curves, churn/expansion, and hiring. Tie it to a scrubbed pipeline categorized as committed/best case/upside, and document pipeline hygiene rules.
Tax Considerations During M&A
Stock vs. asset structure
- Asset purchase: Buyers typically prefer the step-up in tax basis and flexibility to exclude liabilities.
- Stock purchase: Often cleaner for sellers and may preserve contracts, licenses, and certain attributes.
Structure affects purchase price allocation, future amortization, and cash taxes. Align deal, legal, and tax advisors before the LOI so you’re not renegotiating after diligence uncovers something material.
NOLs (Net Operating Losses)
Carryforwards can be valuable but limited (e.g., by ownership changes under Section 382). Keep pristine records of equity issuances and cap table history. Buyers should model both with and without NOL utilization to avoid overvaluing a benefit that’s capped.
Red Flags That Derail Deals
- Unreconciled books: If GL accounts don’t tie to bank, AR/AP, and payroll, the diligence scope (and skepticism) expands.
- Inconsistent SaaS definitions: ARR that doesn’t reconcile to billings and GAAP revenue, or changing churn math across decks, triggers credibility issues.
- Cap table ambiguities: Unapproved option grants, missing board consents, or unclear SAFE conversions can halt closing.
- Revenue recognition errors: Multi-year contracts, discounts, and implementation fees need ASC 606-consistent treatment.
- Tax exposure: Sales tax nexus, misclassified contractors, and payroll tax issues often lead to price chips or escrows.
How Sellers Can Prepare, Starting Now
Work 12–18 months ahead
Close monthly on a schedule. Reconcile every balance sheet account. Lock prior periods. Adopt a clean chart of accounts that maps to SaaS norms.
Standardize reporting
Ship a monthly package that includes: P&L, balance sheet, cash flow, KPI dashboard, ARR/MRR bridge, cohort views, bookings vs. billings vs. revenue, and a deferred revenue roll-forward. Add a short metric glossary so definitions don’t drift.
Build a purposeful data room
Organize folders for Corporate, Finance, Tax, HR/Payroll, Legal, Product, and Customer. Include key contracts (customer and vendor), MSA/SOW templates, compliance and security docs, and state tax registrations. Use consistent naming (YYYY-MM) and track versions. Assign owners to respond to buyer requests quickly.
Tighten tax and equity
Confirm all federal/state returns are filed, sales tax registrations are right-sized, and intercompany/transfer pricing is documented if applicable. Make your cap table the single source of truth and align it to approvals and 409A history.
Validate the forecast
Run sensitivity cases (e.g., +2 pts churn, slower sales ramp, pricing pressure). Tie hiring to pipeline and cash runway. Realistic plans build trust and often speed up confirmatory diligence.
How Buyers Should Evaluate Targets
Commission a quality of earnings (QoE)
A buyer-side QoE tests revenue recognition, normalizes margins, separates one-time/founder-dependent expenses, and clarifies working capital needs. It’s your foundation for negotiations and day-one planning.
Rebuild the drivers
Don’t just accept the forecast, recreate it. Pressure-test win rates, ramp times, renewal assumptions, upsell potential, and hiring timelines. Model downside/base/upside and link each to runway and cash needs.
Prove the “recurring” in recurring revenue
Tie ARR to actual contracts: terms, renewals, price escalators, and termination rights. Sample invoices and cash receipts. Strip out pilots and one-off services from “recurring” claims.
Concentration and timing
Quantify top-10 customer exposure and renewal cliffs. For early-stage companies, one non-renewal can change the story; adjust valuation or structure accordingly.
Tax and structure check
Estimate NOL usability, review sales tax compliance, examine 409A and equity records, and choose a deal structure (stock vs. asset) that supports post-close cash tax efficiency.
Plan the first 100 days
Integration realism wins. Map accounting system migration, KPI definitions, capitalization and revenue policies, and your month-end close timeline. Decide who owns what and when.
Bottom Line
Diligence rewards discipline. Sellers who invest early in clean books, consistent KPIs, and tight tax and equity records move faster and negotiate from strength. Buyers who validate drivers and dig into contract-level revenue make better decisions and avoid unpleasant surprises after closing.
