Why it fits

Three things accounting teams use most.

01

Bulk send for tax season

Upload your client list and every client gets their own engagement letter, filled in.

02

Reminders that respect clients

First nudge after a few days, then on your schedule, never on weekends.

03

Records for seven years

Retention rules keep signed letters as long as your professional body requires.

Can I send the same letter to 300 clients?

Yes. Save it as a template, then use Bulk send with a spreadsheet of names and emails.

Do signers pay?

No. The people you send to never pay, never sign up and never install anything.

Where is our data stored?

In Canada by default. Enterprise plans can choose another region.
