The verdict
For a small team that sends proposals every week and wants the signature and the first payment in one link, I'd pick Better Proposals. The value is the follow-up loop: you see what was read, nudge at the right moment and close. If you run a sales team where several reps send proposals and someone has to approve prices and terms, I'd pick Proposify.
Check the plans on both before you commit. Better Proposals keeps CRM integrations and API or Zapier access off the entry plan. Proposify limits the number of sends on each plan and keeps approvals on the Business plan. Count your proposals and name your CRM first.
