Invoicing Software for British Columbia Accounting Firms

How does invoicing software work for firms in British Columbia?

The CRA administers the GST; the BC Ministry of Finance administers the PST under its own registration and return. British Columbia clients file two separate sales-tax returns — a CRA GST return and a provincial PST return — where an HST province files one.

A British Columbia firm bills its own fees with the federal tax, and whether the provincial 7% tax applies to professional services depends on the province's own rules — check them for your service mix rather than assuming. What does not vary is the value of a priced, signed scope: the fee argument happens at the letter, not at the invoice.

Which CRA deadlines apply?

These rules are federal and apply in every province and territory. Where a due date falls on a weekend or public holiday, the CRA treats the next business day as on time — compute the shifted date each year rather than carrying the calendar forward.

What is different about running a practice in British Columbia?

Four things a firm working British Columbia files should be able to state without looking them up. Each is verified against a primary source, linked at the foot of this page.

Chartered Professional Accountants of British Columbia (CPABC) is the provincial body; 170,512 of British Columbia's 173,246 employer businesses were small businesses as of December 2024.

• Two sales-tax filings, not one — British Columbia businesses register for and file GST with the Canada Revenue Agency and PST with the BC Ministry of Finance separately. A BC bookkeeping client therefore carries two sales-tax cadences on a firm's deadline board, not one.
• CPABC also regulates Yukon — CPABC provides regulation, administration, practice review and licensing for CPA Yukon under agreement, so a BC firm expanding north deals with a familiar regulator.
• Third-largest business base in Canada — British Columbia had 173,246 employer businesses as of December 2024, of which 170,512 were small businesses with 1 to 99 employees.
• 2% provincial small-business rate — British Columbia taxes the first $500,000 of active business income of an eligible CCPC at 2% provincially, on top of the 9% federal small-business rate.

Managing invoicing software across a client book in British Columbia

A firm's billing problem starts before the invoice: unless scope and price were agreed in writing, every bill is a negotiation.

A two-partner Vancouver firm with 90 incorporated clients runs two sales-tax calendars: CRA GST returns on each client's assigned reporting period, and BC PST returns for the retail and services clients that carry a PST registration. Half the corporate clients have non-December year-ends, so the six-month T2 filing clock and the earlier balance-due clock fire in different months than the GST work — which is exactly why one shared board beats two spreadsheets.

How SpidNums handles it

SpidNums models the firm as clients, services and work. Assigning a typed service to a British Columbia client is what generates the recurring projects, the stages and the reminders — the cadence is recorded once rather than remembered each period.

Every open obligation is then ranked by how close its due date sits and coloured accordingly, so the morning question — what is late, what is close, what is fine — is answered by looking.

• Services catalogue with per-service pricing lines
• Engagement letters built from assigned services or prior-year history
• Firm letterhead and branding on every client-facing document
• Client e-signature by type, draw or upload on a no-login page
• Signed PDF stored on the client record
• Annual renewal prompts when scope changes

Where this goes wrong

Billing failures start upstream of the invoice. By the time a fee is being argued about, the mistake was made months earlier.

• The engagement letter is a copy of last year's, so this year's expanded scope is unpriced.
• A client is asked to create an account to sign, and simply does not sign.
• Out-of-scope work is agreed by email and never makes it into the fee schedule.
• Renewals are not prompted, so a three-year-old letter is the only signed scope on file.

What SpidNums does not do

SpidNums is practice management with an invoicing workflow, not an accounts-receivable ledger. It produces the priced, signed engagement that your billing runs from — it does not process payments or age receivables.

If your firm already runs a tracking system it trusts, the honest answer is that you do not need this one. The pages on this site are written to help you decide, not to pretend every firm has the same problem.
