AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
The CRA expects a record of every sale, supported by original documents such as cash register tapes, sales invoices, receipts and bank deposit slips, plus a daily record of income and expenses kept for at least six years. For a grocery that takes cash, the key is a daily close: the till's end-of-day total, a cash count, card and e-transfer totals that agree with it, and the bank deposit. Where records are missing, the CRA says it may determine your income by other methods and disallow expenses you cannot support.
Why cash businesses are looked at closely
A shop that sells ponmo, palm oil, yam and phone credit takes a lot of small cash sales. The CRA's T4002 guide asks every business to keep records of all transactions to support income and expenses, and says that where the information is missing and there is no other proof, the CRA "may have to determine your income using other methods". For a grocery, that usually means the auditor works out what you must have sold from what you bought, using markups, and taxes the result. Good daily records are what stop that estimate replacing your own figures.
The records to keep
T4002 says to keep a daily record of income and expenses, a separate set of records for each business, and duplicate deposit slips, bank statements and cancelled cheques. For income, record the date, amount and source of each amount, supported by original documents such as:
- sales invoices
- cash register tapes
- receipts
- bank deposit slips
- contracts (for example, supply agreements with restaurants)
For purchases, keep each supplier invoice or receipt showing date, seller, buyer, a full description and, for Canadian GST/HST-registered vendors charging $100 or more before tax, their business number. If a till slip has no description, the guide says to write what the item was on it or in your records. Imported stock from Nigeria needs its own trail: supplier invoice, customs entries and freight bills (see CRA receipts for Nigerian supplier costs).
The daily close
One routine covers most of what an auditor asks for. At the end of each day:
- Print or save the point-of-sale end-of-day report (often called a Z report) showing total sales and the split by payment type.
- Count the cash in the drawer, take off the opening float, and write the count on a daily sheet.
- Match card and debit totals to the terminal's settlement report, and e-transfers received to the bank.
- Record any difference (over or short) with a note, not a silent adjustment.
- Deposit cash regularly and keep the deposit slip with the day's sheet.
Worked example (illustrative)
| Line | Amount |
|---|---|
| POS total sales | $2,340.00 |
| Card and debit (terminal settlement) | $1,580.00 |
| E-transfers received | $150.00 |
| Cash expected ($2,340 − $1,580 − $150) | $610.00 |
| Cash counted (after removing $200 float) | $605.00 |
| Short | $5.00, noted on the daily sheet |
A $5 shortage recorded every so often looks like a real shop. Days that always balance to the cent, or cash that is never deposited, are what invite questions.
Things that cause trouble
- Sales rung up as "no sale" or voided after the customer leaves.
- Cash used to pay suppliers or staff straight from the till with no record: pay from the bank, or record each one with a voucher.
- Personal shopping from stock: record it as drawings at cost.
- Phone credit, money transfer or courier agency sales mixed into grocery sales: keep agency commissions separate.
- Software or settings that edit or delete sales history: keep the POS audit trail intact and switch off any option to purge past sales.
Weekly and monthly checks
The daily close catches mistakes; a short weekly and monthly review catches patterns. Once a week, compare the total of the daily sheets with the deposits that reached the bank. Once a month, compare purchases with sales: if you bought 40 cartons of stockfish and sold 25, the remaining 15 should be on the shelf or in the storeroom. A rough stock count at month end, even of only your top twenty lines, gives you the same view an auditor would build, before the auditor builds it. Write down the gross margin you expect on your main lines; a month far off that figure is worth explaining while you still remember why (a price change, spoiled stock, a bulk order for an event).
Keep staff and family use of stock on a simple list that is entered as drawings or staff benefits. Unrecorded "we took some yam home" is a small leak in the shop and a large gap in a markup-based estimate.
How long and where
The CRA says records must generally be kept for six years from the end of the last tax year they relate to, at your place of business or residence in Canada unless it gives written permission to keep them elsewhere. Electronic records are acceptable; if your POS is cloud-based, make sure you can export the full sales history for the six years, not just the last few months, and keep a copy in Canada. Destroying records early without permission can lead to prosecution.
Starting out? The licence side is in licensing an African food store in Toronto, and registering for GST/HST in GST/HST registration for a new business.
Where Pryme fits
For a grocery with suppliers in Nigeria, a Pryme Business Account can pay those suppliers in naira, with a receipt for each payment that goes straight into your purchase records. Statements and receipts can be generated as verifiable documents through VerifyDoc.ai (receipts), which helps when an auditor asks you to prove a foreign purchase. Your Canadian till, card terminal and bank stay as they are.
Questions people ask
What sales records does the CRA expect from a small shop?
A daily record of income supported by originals such as cash register tapes, sales invoices, receipts and deposit slips, kept for at least six years.
What happens if my cash records are incomplete?
The CRA says it may determine your income using other methods and may disallow expenses you cannot support.
Do I need to keep POS end-of-day reports?
Yes. They are the daily summary of sales by payment type and the starting point for reconciling cash, cards and deposits.
Can I keep my shop's records only in the cloud?
Electronic records are acceptable, but they must be kept or accessible in Canada and cover the full six years; export and keep a copy.
