Most pre-sale checklists are about the app: clean revenue data, cohort exports, account transfers, IP assignments. Those matter, and buyers will check every one of them. But the founders who come through a sale most satisfied have usually done a second kind of preparation, on themselves. They knew what they needed from the deal, who else had a say, and what they were willing to give after closing. Founders who skip that work tend to find the answers in the middle of a negotiation, which is the most expensive place to look for them.
1. Know the number you need, not just the number you want
The figure founders carry around is usually a headline price, often borrowed from someone else's exit. What lands in your account is different. Fees, taxes, any part of the price paid later through an earnout or held back in escrow, and the transition time you commit to all sit between the headline and your net. Work out the net number that would make selling worthwhile for you, and the structure you would accept to get there. A founder who knows that number can judge an offer in an afternoon. One who does not tends to anchor on the biggest headline, even when a smaller, mostly cash offer would leave them better off.
2. Get tax advice before the letter of intent, not after
How an app sale is structured can change what you keep. Whether the buyer purchases the assets or the company, how the price is allocated, how an earnout is treated, and whether the app sits in a company or in your own name all carry tax consequences. Those are questions for a tax professional, and the time to ask them is before you sign a letter of intent, while the structure is still open. Once the terms are agreed, the room to change them is small.
3. Find everyone who has a say
A co-founder, an early angel with a small stake, a developer who was promised a share of any exit, a partner on a revenue-share deal. Any of them can slow or complicate a sale if they hear about it late. List everyone with equity, a contractual right or a reasonable expectation, and have the conversation before a buyer is involved. A disagreement found in month one is a conversation. Found in diligence, it is a delay a buyer may not wait through.
4. Decide how much of yourself is for sale
Most app buyers want some transition support: walking them through the codebase, introducing them to key partners and vendors, answering questions while they learn how the app runs. Decide in advance how many months and hours you can give, and on what terms. Think about the non-compete as well. If your next idea is an app in the same category, a broad non-compete can rule it out for years. Know what you plan to build next before you agree to what you will not build.
5. Plan to keep running the app while it is for sale
A sale takes months, and buyers watch the numbers the whole way through. A founder who mentally checks out after the first offer often sees installs or renewals soften just as diligence starts, and the price follows. Decide how you will keep marketing, shipping updates and answering support while the process runs, and who, if anyone, needs to know about the sale. Contractors and users usually do not, at least not yet.
The takeaway
Buyers prepare carefully to buy your app. The founders who sell well prepare just as carefully on their own side: their net number, their tax position, the people with a say, their terms after closing, and a plan for running the app until the deal closes. None of it shows up in a data room. All of it shows up in the outcome.
