It removes the biggest unknown
Every buyer is trying to work out what happens to revenue after the founder leaves. Contracts and subscriptions answer that question before it is asked.
This is why maintenance agreements, monitoring, service plans and managed contracts have such a disproportionate effect on valuation.

Two identical businesses, one contracted and one not, can receive offers with the same headline and very different levels of certainty.
Building it before you sell
Convert informal repeat work into annual agreements. Add a service or support plan to what you already deliver for free. Move ad-hoc billing to monthly direct debit.
Even twelve months of this shows up clearly in the numbers — and in the offer.
