The short answer
Evaluate the whole bargain: guaranteed payment, scope, exclusivity, permitted uses, liability, effort and timing. A headline number is insufficient.
Compare like for like
Seek a second proposal for the same scope where appropriate and permitted. Ask each provider to make conditions and deductions explicit.
Keep unknowns visible
Use the offer worksheet to list missing clauses and questions. It intentionally does not score a deal or invent a market price.
What to record before deciding
Keep the written scope, official provider source, unresolved questions and the person responsible for each check. Treat a marketing claim as a claim until it is reflected in the agreement. A directory entry does not approve the transaction or establish your rights to share the records.
