A Monthly Bookkeeping Routine for a One-Person Business
Most bookkeeping problems don’t start on a busy week. They start on a quiet one — the week you tell yourself you’ll catch up on receipts later, and later becomes a shoebox you’re afraid to open before you file, usually right around March.
A monthly bookkeeping routine for a one-person business doesn’t need to be elaborate. It needs to happen on the same handful of days every month, whether the business is quiet or not.
Capture receipts the day money moves
The habit that matters more than any app or spreadsheet is capturing the receipt the day the money moves. A photo taken at the till, filed into a folder by month, beats a pile of paper sitting in a jacket pocket for six weeks. If you’re using accounting software, most let you snap and attach a receipt to the transaction in seconds — do it before you’ve left the parking lot, because that’s the moment you still remember what it was for.
Reconciling against the bank statement
Once a month, sit down and match what your books say against what your bank statement actually shows. This is where errors surface — a duplicate entry, a payment that never went through, a subscription you forgot you were still paying. Reconciliation is the single check that catches small mistakes while they’re still small, instead of compounding for eleven more months.
Keeping business and personal expenses apart
Separate the personal from the business from day one — a dedicated business bank account and card, even before you’ve formally set anything up, saves hours later trying to remember which coffee was a client meeting and which one wasn’t. Categorise expenses consistently — the same handful of categories every month — and note who or what a purchase was for while it’s still fresh, directly on the receipt or in the transaction memo.
When the till slip fades
Thermal till slips fade within months, sometimes weeks, and a faded receipt with no visible amount is close to useless as a record. The fix is simple and worth doing the same day you get the slip: photograph it, or staple it to a plain sheet with the amount and vendor written by hand alongside it. Don’t wait until year end to discover the ink is gone and the transaction is now unprovable. That’s what to do about a faded till slip — act on it the same day, not months later.
A checklist short enough to actually use
A short, repeatable list beats a long one you never finish: - File every receipt from the month, digital or photographed - Reconcile the bank and credit card statements against your books - Confirm every expense has a category and a note - Set aside the estimated tax portion of anything you’ve earned, so it isn’t a surprise later - Back up your records somewhere other than the device they were created on
None of this replaces an accountant or bookkeeper who knows your specific situation — GST/HST registration and what counts as a deductible expense are areas where a Canadian accounting professional earns their fee, and getting that relationship started early is worth more than trying to learn Canadian tax rules from scratch while also running a business.
The payoff
A business that reconciles monthly walks into tax season with an answer already prepared, instead of a scramble. That’s the entire case for the routine — not that it’s exciting, but that it turns a dreaded annual task into twelve small ones you’ve already done.
