Tracking expenses is less about entering every detail perfectly on day one and more about building a routine that keeps each transaction understandable. A useful record should tell you what happened, when it happened, which Business it belongs to and what evidence supports it.

The Canada Revenue Agency says businesses must keep records that support income and expense claims. Its guidance also says to keep separate records for each business you run. That makes separation and supporting documents the foundation of a dependable system.

1. Give every Business its own record set

If you operate more than one company or activity, do not combine their expenses in one undifferentiated list. Choose the correct Business before recording a purchase, and keep its receipts, notes, trips, invoices and bank activity together.

This prevents a common month-end problem: a transaction exists, but nobody can confidently say which Business used it.

2. Capture purchases while the details are fresh

For each expense, record:

• purchase date;
• supplier or plain-language description;
• amount and currency;
• expense category;
• payment source;
• Business purpose; and
• receipt or other supporting document, when available.

Avoid vague notes such as “supplies.” A short description like “printer paper for client packages” gives a future reviewer useful context without turning recordkeeping into an essay.

3. Separate payment method from Business purpose

A valid Business purchase can be paid from a Business account or personally by an owner. Record the expense once, then identify how it was paid. If the owner paid personally, track the amount that may need to be repaid instead of recording a second expense later.

That distinction keeps the purchase record and the repayment record connected while avoiding duplicate totals.

4. Attach evidence and flag exceptions

The strongest record combines the transaction with its receipt, invoice, agreement or other voucher. If evidence is temporarily missing, do not ignore the transaction. Record what you know, add a factual note and place it in a follow-up queue.

The CRA’s business-record guidance explains what expense receipts should contain and suggests writing transaction details in an expense journal when a supplier does not provide a receipt. Your accountant or tax professional can advise what support is appropriate for your circumstances.

5. Review weekly, close monthly

A short weekly routine keeps the backlog small:

1. Capture new receipts.

2. Categorize uncategorized purchases.

3. Confirm owner-paid expenses.

4. Follow up on missing evidence.

5. Check that each record belongs to the right Business.

At month-end, compare your expense records with relevant bank or card activity. Investigate unmatched items, review unusual amounts and note anything that still needs a decision. The goal is not to silently guess—it is to make open questions visible.

A simple expense record checklist

Before marking the month ready, confirm that:

• transactions are assigned to the correct Business;
• categories are reasonable and consistent;
• receipts are attached where available;
• missing evidence is acknowledged and followed up;
• owner-paid purchases are clearly identified;
• repayments do not exceed outstanding owner-paid amounts; and
• duplicate entries have been investigated.

SilaTrail helps keep expenses, receipts, owner repayments and review items together by Business. It organizes the recordkeeping workflow; it does not decide whether a cost is deductible or calculate tax payable.
