How to do bookkeeping for a small business (Canada)
The actual monthly bookkeeping routine for a Canadian small business, step by step — plus the honest signs it’s time to stop doing it yourself.

Bookkeeping isn’t mysterious; it’s a routine. Do the same handful of things every month and your books stay current, your HST is ready, and tax season is boring. Skip a few months and it becomes the dreaded catch-up job. Here’s the routine.
Set it up once
- Separate the money. A dedicated business bank account and card. Mixing personal and business is the single biggest cause of messy books.
- Pick your system. Software you’ll actually keep up with — or a system that’s set up and run for you if you won’t. Be honest about which you are.
- Register for HST when you cross the line. $30,000 in revenue over four quarters — see how to get an HST number.
The monthly routine
- Record income. Every sale and invoice, with HST, matched to what actually landed in the bank.
- Record expenses. Every bill and receipt, categorised, with the image kept — that’s your input tax credits and your proof.
- Reconcile the bank. Match your books to the bank statement so nothing is missed or double-counted. This is the step people skip and regret.
- Check who owes what. Chase overdue invoices; note upcoming bills.
- Read one number. At minimum, know whether you made money this month. That’s the point of all of it.
If reading that list made you tired, that’s the honest signal — Pocket Ledger runs this routine for you so being current is the default. See what’s included or book a setup call.
When to stop doing it yourself
DIY works until it doesn’t. The usual tipping points: receipts pile up, reconciliation slips for a couple of months, or the bookkeeping is eating evenings you’d rather spend on the business. If you’re already behind, that’s catch-up bookkeeping — fixable, and worth doing before it compounds. We went deeper on the decision in do I need a bookkeeper?.
The set-up-for-you version
The same routine, without you running it: we set up a real accounting system around your business and run it for one fixed price, and you handle the everyday capture from a chat — send a receipt, invoice a customer, ask what you owe in HST. See our bookkeeping services or the price.
Questions
Can I do my own small business bookkeeping?
Yes, especially early on with a clean setup and the monthly routine above. The question is whether it’s the best use of your time as the business grows.
How often should I do my books?
A little and often beats a big catch-up. Weekly capture and a monthly reconciliation is a good rhythm for most owners.
What’s the hardest part?
Reconciliation and staying consistent. The mechanics are simple; the discipline is the work — which is exactly the part a set-up-for-you system removes.
