The template trap
Most agencies have a folder of templates with names like 'Proposal FINAL v3'. Someone copies one, edits for 45 minutes, and sends it.
Why static templates fail
The issue is not templates themselves, it is that they are static. They cannot adapt to each client's needs, budget, or industry without manual work.
A living proposal library
A better approach is a living library. Your team defines services, pricing rules, and tone once. AI assembles the right pieces for each client so proposals stay consistent without repetitive editing.
