A receipt system for sole proprietors that actually sticks

Every sole proprietor has built a receipt system at least once: a folder, a drawer, a camera-roll habit. Most of them were abandoned by week three. The problem isn't discipline. It's that most systems demand work later, and later is exactly when you're busiest. Here's what you actually need to keep, why systems fail, and a version that survives contact with real life.

What you actually need receipts for

The deductions Canadian sole proprietors claim most, and the evidence each one needs:

• Home office: a reasonable share (usually workspace area ÷ home area) of rent or mortgage interest, utilities, insurance, property tax (CRA: business-use-of-home). Evidence: the household bills themselves.
• Vehicle: the CRA expects a logbook (date, destination, purpose, kilometres) to establish your business-use percentage, and every fuel, insurance, and repair receipt to establish the costs (CRA: motor vehicle records). The log without receipts, or receipts without the log, is half a claim.
• Meals: deductible at 50%, tips and taxes included (CRA: line 8523). Auditors ask who and why. Note it when you save the receipt, not eight months later.
• Phone & internet: the business-use portion, on an allocation you can defend.
• Supplies and everything else: the general test is simply that the expense was incurred to earn business income and is reasonable, backed by a document.

What counts as that document? A receipt showing the date, the seller, and what was bought. When there's genuinely no receipt (parking meters, market stalls), the CRA itself says to record the seller, date, amount, and details in an expense journal (CRA: business records). Card statements alone prove payment, not purchase. Keep both.

Why your last system failed

Because it deferred the work. The envelope, the drawer, the "I'll sort them monthly" folder: they all separate the moment you get the receipt from the moment you deal with it. Every deferred receipt is a small loan against April, and April always calls it in: a pile of half-faded thermal paper, a camera roll where receipts hide between family photos, and a bookkeeper charging by the hour to archaeology through it. Bookkeepers even have a name for it: shoebox clients.

The fix is behavioural, not organizational: capture at the moment of purchase, or it doesn't happen. Any system that requires a second touch has already failed. The receipt's job should be finished before you leave the counter.

The four-rule system

1. Snap it at the counter. Ten seconds, before the receipt enters a pocket. The photo is also the preservation step: thermal print is at its most legible the moment it's printed, and the CRA accepts proper images as permanent records.
2. One place, not three. All of it goes to a single dated list, not camera roll + email + glovebox. Findability in year six is the whole point.
3. Note the context that fades faster than ink. For meals: who and why, typed at capture. For odd expenses: one line about the job it served.
4. Ten minutes at month-end, then share. Skim the month's list, fix anything the scanner misread, and give your bookkeeper access during the year, not a shoebox after it. If your tool exports a clean CSV with the photos attached, year-end becomes an email, not an excavation.

And keep it all for six years

Whatever you capture has to survive: the CRA can ask for support six years after the end of the tax year it relates to. Paper won't make it that far; a well-kept photo will.
