The Diligence File Every App Founder Should Keep (Long Before a Sale)

Most app deals don’t fall apart on price. They fall apart on transferability — the discovery, six weeks into diligence, that something the buyer assumed was simple is not. Almost all of it is preventable, and the prevention is unglamorous: a diligence file, kept current, long before any sale is on the table.

1. The accounts that actually transfer

App Store and Google Play accounts, and everything hanging off them: certificates, signing keys, admin access. Buyers check what transfers, on what terms, and who has to consent. An app sitting inside a personal developer account tangled with unrelated projects is a solvable problem — but it’s a problem better solved a year early than mid-deal.

2. IP ownership, on paper

Did every contractor who touched the code sign over their work? Is the trademark registered, and to the right entity? Buyers’ counsel will ask for chain-of-title on the IP, and “it was all handshake deals with freelancers” is the answer that turns a clean deal into an escrow-heavy one.

3. Code and infrastructure documentation

The buyer’s technical reviewer wants to know: can someone who isn’t you run this? Documented build processes, a current dependency list, third-party SDK inventory (and their license terms), crash and refund rates, and infrastructure that isn’t secretly held together by a personal account or an unpaid-tier service.

4. The analytics buyers always request

Revenue by product and channel, exportable from the systems of record — RevenueCat, Stripe, AdMob, the app stores themselves. Cohort retention. Acquisition mix, organic versus paid, by period. When the numbers in your deck reconcile cleanly to the numbers in the systems, diligence accelerates. When they don’t, everything you’ve said gets re-verified — and re-priced.

The takeaway

A diligence file is not paperwork for a sale you haven’t decided on. It is proof your business can operate without you — which happens to be the exact thing buyers pay premiums for. Founders who keep it current sell faster, at better terms, to buyers who trust the numbers.
