How to Sell a Micro SaaS With Verified Revenue

Updated 2026-07-17 · ShowMRR Team · showmrr.com

Selling a small SaaS is mostly a trust problem. A buyer needs to decide whether the revenue is real, whether the asking price is reasonable, and whether the founder is serious enough to complete a transfer.

This guide explains the exact funnel we built and tested on ShowMRR: verify revenue, calculate a comparable multiple, publish profit margin, and accept only email-verified buyer inquiries.

1. Verify revenue before asking buyers to trust it

Screenshots can be stale or edited. A marketplace listing is more credible when revenue is synced from a payment provider. ShowMRR supports revenue verification through Stripe, LemonSqueezy, and Polar and shows the result alongside the startup.

Founders can verify one startup on the Free plan. The paid decision happens when the founder wants acquisition distribution, not before the revenue is proven.

2. Set an asking price buyers can compare

A raw asking price is not enough. ShowMRR calculates the valuation multiple from the asking price and annualized verified MRR:

Valuation multiple = asking price / (verified MRR × 12)

For example, a startup with $1,200 MRR and a $24,000 asking price has a 1.7x annualized revenue multiple. The server calculates this value so it cannot drift away from the verified revenue shown to buyers.

3. Add the last 30 days profit margin

Two products with the same MRR can have very different economics. ShowMRR requires a profit margin between 0% and 100% and places it next to MRR, price, and multiple on the marketplace card.

4. Keep the buyer funnel short, but verify the email

Requiring an account before an initial offer adds friction. Accepting every anonymous message creates spam. ShowMRR uses a short offer form followed by a six-digit email code.

An inquiry remains pending for ten minutes and reaches the founder only after verification. Invalid or expired codes are rejected, and codes are stored as hashes rather than plaintext.

5. Charge for the outcome, not the database row

Revenue verification is free. The Sell tier is a $49 one-time purchase that unlocks the acquisition listing and verified buyer inquiries. Payment is tied to the founder outcome: reaching a credible buyer.

What we tested end to end

1. A verified seller creates a listing with asking price and profit margin.
2. The server calculates the multiple from verified MRR.
3. A buyer submits an offer without creating an account.
4. An incorrect verification code is rejected.
5. The correct code delivers the inquiry to the seller dashboard.
6. A seller without access sees a direct $49 Sell upgrade path and returns to listing after checkout.
