Illustrative scenario: a Halifax solo CPA getting every engagement letter signed
A solo Halifax CPA carrying roughly 120 clients has the same documentation obligation as a hundred-person firm: provincial CPA codes of professional conduct require the terms of an engagement to be in writing. The practical problem is not drafting the letter — it is getting it back, signed, before the work starts.
The firm in this scenario
An archetype, not a client. The figures below describe the shape of the practice being modelled — they are inputs to the scenario, never results.

The problem
Letters are drafted in Word, printed, and sometimes never returned. Work starts anyway, because the client is waiting and the deadline is not.
Scope creep then has nothing to push against. Without a signed scope, every 'I thought that was included' conversation is a negotiation, and at renewal the documentation gaps are visible all at once.
The workflow, step by step
- 1
Build the letter from the services catalogue
Pricing lines load from the client's assigned services or from last year's letter, so the scope and the fee are written from the same source.
Services-based engagement letters
- 2
Send a branded, no-login link
The client opens the letter on the firm's own letterhead and branding. No account, no password, no portal invitation to ignore.
Public client portal
- 3
Let the client sign the way they want
Signature by typing, drawing or uploading — the three options that cover the client who is on a phone and the client who insists on a scanner.
E-signature
- 4
Keep the signed PDF on the record
The executed letter lands on the client record, where it is findable at renewal and at practice inspection without searching an inbox.
Client record archive
- 5
Prompt the renewal
The letter is flagged annually and whenever scope changes, so the file does not run for three years on a two-year-old scope.
Reminders
What this changes
A solo practitioner in this position typically ends up with a signed, priced scope on file for every active client. That artifact is what scope-creep conversations and practice inspections both come down to, and it is far easier to produce before the work than after the invoice.
