The Business Proposal Letter template takes a warmer, letter-first approach: it opens with a personally addressed letter instead of a formal overview, then backs it up with an offer summary, a three-phase delivery plan, an investment table with a computed total, and an acceptance page with inputs and signatures — five pages in all.
Edit the letter in your own voice in Bonsai, and let merge fields address it to the right contact automatically. The offer, duration, and validity stat cards keep the commercial details scannable, and the built-in signature blocks turn a good letter into a signed deal.
Everything below comes pre-configured. Turn sections on or off, edit the copy, or add your own — Bonsai remembers your choices for next time.
Can I edit every section? Yes — every heading, paragraph, stat, table row, and signature block is fully editable in Bonsai.
Can I add more pages? Yes — add, reorder, or duplicate pages once the template is open.
Do merge fields auto-fill? Yes — Sender, Receiver, and Date pull from your client contact and the current date automatically.
How is this different from a standard proposal? It leads with a personal letter rather than a formal overview — better for warm introductions and smaller engagements where tone matters as much as scope.
