7 Due Diligence Red Flags That Kill Indie Acquisitions

Most founders assume the hard part of selling is negotiating the price. In reality, more indie deals collapse during due diligence than at the negotiating table. An agreed price means nothing until the buyer has verified the business behind it, and that's where deals quietly fall apart.

Here are the seven red flags that make experienced buyers walk, and how to clear each one before it costs you the deal.

1. Revenue That Doesn't Reconcile

The buyer cross-checks your stated MRR against Stripe, your bank, and your tax returns. If those three numbers don't match, trust evaporates instantly. Fix it early: reconcile all three yourself before listing, and be ready to explain any gap (refunds, annual plans, currency).

2. Aggressive Add-Backs

Inflating SDE with questionable "business expenses" (a personal car, vague consulting, home renovations) is the single fastest way to make a buyer doubt everything else. Fix it: only add back costs a new owner genuinely won't inherit, and document each one.

3. Hidden Customer Concentration

If your top customer is 30% of revenue and the buyer discovers it in diligence rather than your listing, the deal is already wounded. Fix it: disclose concentration up front and frame the mitigation (contracts, tenure, satisfaction).

4. Undisclosed Churn Trend

A business with a flat MRR headline can be hiding rising churn masked by a few large new customers. Buyers model the trend, not the snapshot. Fix it: show monthly churn and net revenue retention honestly. A stable business with disclosed 3% churn beats a "growing" one with a hidden leak.

5. Platform or Single-Channel Dependency

A business that lives entirely on one API, one ad account, or one viral channel is one policy change away from zero. Fix it: you may not be able to remove the dependency, but disclosing it and showing diversification efforts keeps the buyer at the table.

6. Messy or Missing Legal Ownership

Who owns the domain? The trademark? The code a contractor wrote three years ago? If ownership is unclear, the asset transfer itself is at risk. Fix it: confirm you legally own everything you're selling, and have the contractor IP assignments in writing.

7. Founder-Dependent Operations

If the business only runs because you personally do five critical things every week, the buyer isn't buying a business, they're buying your job. Fix it: document processes, automate what you can, and prove the business ran without you for at least a month.

The Pattern Behind All Seven

Every one of these red flags is really the same problem: a surprise that surfaces late. Buyers don't walk because a business is imperfect, every business is. They walk because something they weren't told about appears halfway through diligence and makes them wonder what else is hidden.

The antidote is radical transparency before you list. Put the warts in the listing. Build the data room. Reconcile the numbers. The deals in the FounderSold database that closed at strong multiples weren't flawless businesses, they were honest ones.
