When you start working for yourself, “bookkeeping” can sound like a whole second job. For a sole proprietor, a few repeatable habits can keep business numbers separate, current, and easier to explain. Consistency can reduce later cleanup.
Here is a beginner’s system you can set up this week. It is general information, not tax or accounting advice — for anything specific to your situation, check the CRA or a qualified professional.
Step 1: Separate business from personal
The single most valuable habit is keeping business money apart from personal money. A dedicated bank account (and card) for the business means your records are not tangled with groceries and Netflix.
This one decision can make later review easier: statements become a rough map of business activity, mixed-use purchases stand out, and personal spending is easier to separate from items that may need business-expense review.
Step 2: Track money in and money out
Bookkeeping comes down to two questions: what came in, and what went out. As a sole proprietor you want a running record of:
- Income — what you invoiced and were paid, with dates and clients.
- Expenses — what you spent to earn that income, with receipts.
You do not need enterprise accounting software on day one. What you do need is a system where nothing falls through the cracks. The most common failure is not bad math — it is a missing receipt or an uncategorized charge that nobody can explain six months later.
Step 3: Capture receipts the moment you get them
Receipts are the evidence behind every expense. Thermal-paper receipts fade, paper gets lost, and email receipts disappear into an inbox. The fix is to capture them immediately, as a clear image, with the merchant, date, total, and tax legible.
For each business receipt, get into the habit of capturing:
- a legible image,
- a category (so it is sorted while the context is fresh),
- the GST/HST line if you are registered, and
- a short note for anything where the business purpose is not obvious.
If you drive for work, treat mileage as part of the same routine — log trips as they happen rather than reconstructing them later. The CRA mileage deduction guide covers records that can support later review.
Step 4: Decide whether GST/HST applies to you
The CRA’s $30,000 small-supplier test uses this calculation for a sole proprietor. The calculation totals revenue before expenses from worldwide taxable supplies across all of the proprietor’s businesses. It includes zero-rated supplies and revenues of associates that were associated at the beginning of the particular calendar quarter. It excludes GST/QST amounts themselves, supplies of financial services, sales of capital property, and goodwill from the sale of a business. If a business exceeds $30,000 in a single calendar quarter, small-supplier status ends on the supply that crosses the threshold, registration is effective no later than that supply, and GST/HST must be charged on that supply. If it exceeds $30,000 over the previous four or fewer consecutive calendar quarters, but not in a single calendar quarter, small-supplier status ends at the end of the month following the crossing quarter, registration is effective no later than the first later supply, and charging starts on the effective date. Taxi and commercial ride-sharing operators generally must register from the start, and voluntary registration may be possible.
In Quebec, Revenu Québec administers GST/QST where applicable. Confirm your registration timing and obligations with the CRA, Revenu Québec, or a qualified professional. If you are registered, preserve the tax shown on relevant receipts for review. Input tax credit eligibility depends on registration, eligible commercial use, required evidence, and time limits; a captured field does not establish eligibility or filing accuracy.

Step 5: Set a review cadence
Bookkeeping fails when it becomes a once-a-year archaeology project. The antidote is a small, regular review:
- Weekly (5–10 minutes): scan any receipts you missed, categorize new items, add notes.
- Monthly: confirm income recorded matches what you were paid, and check nothing is uncategorized.
- Quarterly: review before any GST/HST or instalment dates so there are no surprises.
This rhythm can reduce later cleanup. If you want a starting routine, see how to organize receipts for taxes in Canada.
Step 6: Keep records you could hand over tomorrow
Good bookkeeping is records you could explain if someone asked. That means legible receipts, sensible categories, notes on unusual items, and the ability to export PDF and CSV reports for later review by your accountant or the CRA.
Knowing your deadlines closes the loop: see self-employed tax deadlines in Canada so you know when these records need to be ready.
PKTD is designed for this beginner workflow. On-device OCR reads receipt text, and consent-gated optional AI can suggest structured fields for review. PKTD also keeps business-mileage records and exports CSV/PDF reports. You can download PKTD on the App Store.
The takeaway
Sole proprietor bookkeeping is not a second job — it is six habits: separate your money, track income and expenses, capture receipts immediately, handle GST/HST if it applies, review on a cadence, and keep records you could hand over tomorrow. Start small, stay consistent, and the books stay quiet.
