Before you choose, sanity‑check these:

  • Do you need a client portal or just internal workflows?
  • Do you need approvals/sign‑offs (and an audit trail)?
  • Which integrations are non‑negotiable (email, accounting, calendar, Slack)?
  • How fast do you need to be live (today vs. next week)?

Retainer proposals fail for boring reasons: version chaos, slow approvals, unclear scope, and weak follow‑ups. These picks optimize for speed to signature and clean handoff.

If you just want a fast answer:

  • Best overall: Proposify — proposal-first workflow with good structure for agencies.
  • Best docs + signing combo: PandaDoc — solid templates plus e‑signature.
  • Best lightweight option: Better Proposals — simple proposals when you want less process.

  • Prioritized low-friction setup and sane permissions (so you actually adopt it).
  • Checked reporting and “share with clients” realism (not just feature checkboxes).
  • Included a clear watch-out for each option to avoid bad fits.

We refresh guides when pricing/features shift. Always verify current terms on the vendor site.

  • Helps reduce “which version is final?” chaos.
  • Works well when proposals are a core part of your growth engine.

FAQ

What’s the fastest way to improve close rate?

Reduce friction: clear scope, clear next step, and a simple signing flow.

Should proposals live in Google Docs?

Docs work early on, but tools help once you’re collaborating, tracking views, and managing versions.

How do I keep retainers from drifting?

Include scope boundaries and a change process in the proposal — then reference it during onboarding.
