System & Custom Templates

Start from built-in templates, customize them for your firm, or write your own. A Source badge marks each one.

Universal or Country-Specific

Set an optional country on a template, or leave it blank to apply everywhere your firm works.

E-SIGNATURE

Clients Sign in Seconds — No Account Needed

Send a secure link and the client reviews and signs online. They draw or type their signature, agree to the terms, and you both get a confirmation — no printing, scanning, or PDF email attachments. The signed letter is filed alongside your other client documents.

Draw or Type

Clients sign the way they prefer, on any device, with an explicit agreement to the terms before accepting.

Reminders & Resends

Resend a reminder with one click if a letter goes unsigned, or cancel it if plans change.

Signed PDF Kept on File

The signed letter is stored with the engagement and a confirmation copy is emailed to the client automatically.

The signed letter is saved with the engagement and emailed to the client.

Frequently Asked Questions

You send a secure link by email. The client opens it without needing an account, reviews the letter, and signs by drawing or typing their signature after agreeing to the terms. A confirmation copy is emailed to them automatically, and the signed PDF is stored with the engagement.

Merge fields are variables like {{client_name}}, {{engagement_title}}, {{fee_amount}}, and {{letter_date}} that you insert into a template. When you generate a letter, CPA Buddy replaces them with the real values for that client and engagement, so letters are accurate and personalized without manual editing.

Yes. Each letter has a status — Draft, Sent, Viewed, Signed, Declined, Expired, or Cancelled — so you can see whether the client has viewed it and whether it has been signed. You can resend reminders or cancel a letter at any time.

No. You can start from built-in system templates, customize them for your firm, or create your own. Templates are organized by service type, so you reuse consistent language across tax, bookkeeping, audit, advisory, and other engagements.
