Truss engagement letter workflow

Build your templates once, then send personalized agreements to every client in minutes. Merge fields pull in client names, return types, and fees automatically. Your season starts moving.

Bulk engagement letter send across projects

Send hundreds in one bulk action.

Pick the projects, pick a template, and Truss generates a personalized engagement letter for each one.

Merge fields that resolve per entity type

Merge fields that know your entity types.

Placeholders like [all_full_names], [first_name], [nickname] and [entity] resolve per project — including joint-filer households where two names need to appear on the same letter. You write the template once and trust it across 1040s, 1120-S's, and 1065s.

Template edits push to every unsigned letter

Edit a template, refresh every unsigned letter.

Find a typo at 9pm? Update the template and Truss pushes the new version to every pending letter that hasn't been signed yet. The already-signed ones stay locked exactly as they were sent.
