Selling a SaaS: What to Prepare Before You List

Most founders who decide to sell a SaaS product underestimate how much the preparation phase affects the outcome. The difference between a deal that closes at asking price and one that stalls or closes at a significant discount often comes down to what happened in the weeks before listing.

The Most Common Mistakes

Listing before the metrics are ready. If churn is high or MRR has been declining, buyers will see that. A focused period of improvement before listing, even just a few months, can meaningfully change the multiple you can justify.

No documentation. A buyer who cannot figure out how to run the product without you from day one is not going to close. Write down how the business runs before you list, not after someone asks.

Talking to only one buyer. Single-buyer negotiations almost always end at a lower price. The goal is to have multiple buyers engaged at the same time.

Hiding problems. Buyers do due diligence. They find things. When they find issues that were not disclosed, deals either fall apart or reprice dramatically.

The Pre-Sale Checklist

Financials: MRR trend for the past 12 to 24 months, monthly churn rate, average revenue per user, refund rate, and revenue evidence from the actual payment platform.

Technical: Tech stack documented, hosting and service costs itemized, deployment process written down.

Operational: Standard operating procedures for support, billing, and recurring tasks. A list of any contractors or external dependencies.

Legal: Proof of ownership of the domain, code, and any intellectual property. Any contracts with customers or vendors that will transfer.

The Listing Strategy

Set a listing price based on your ARR multiple and the quality of your metrics. Back it with specific data. To get to a defensible number, walk through our SaaS valuation calculator guide or the broader SaaS business valuation methodology. Engage multiple buyers at the same time and give each offer proper consideration rather than responding to whichever arrived first.

On Sidemarket, your key metrics are verified through integrations before you list, so buyers are already working with trusted data from the first conversation. Less time proving numbers means more time focused on the deal itself. For the end-to-end flow once you’re ready, see our guide to selling a SaaS business.
