How to Do Accounts Receivable for a Small Business in Canada

You sent an invoice two weeks ago and the client still hasn't paid. Meanwhile, you are chasing them by email, your bank feed is a mess of uncategorized deposits, and you are not sure if you accounted for the GST/HST correctly on that last sale. If this sounds familiar, you need to know how to do accounts receivable for a small business in Canada the right way. Accounts receivable (AR) is the money your customers owe you for goods or services you have already delivered. Getting AR right is not just about sending invoices. It affects your cash flow, your tax filings, and your relationship with clients.

Small business owners in Canada face specific challenges: different provincial sales taxes, CRA remittance deadlines, and the need to track payments accurately for year-end. This guide walks through every step of the AR process, from setting up invoices to handling late payments, with practical tips and Canadian context. Whether you are a solo freelancer or run a growing team, these practices will keep your receivables under control.

The Basics of Accounts Receivable for Canadian Small Businesses

Before diving into process, it helps to understand what accounts receivable is and why it matters differently in Canada. AR is an asset on your balance sheet. It represents sales you have made but cash you have not yet collected. For a Canadian small business, this includes sales with GST/HST, QST (Quebec), or PST (British Columbia, Saskatchewan, Manitoba). You must remit these taxes to the CRA (or Revenu Quebec) on time, regardless of whether your customer has paid you yet. That mismatch creates a cash flow squeeze if your AR is slow.

Another Canadian nuance: many small businesses operate on net 30 terms, but in practice, payments often stretch to 45 or 60 days. Meanwhile, CRA expects GST/HST remittances quarterly or annually depending on your revenue. If you use the quick method of accounting for GST/HST, your remittance rate is lower, but you still need accurate records of your taxable sales.

Key Accounts Receivable Terms

• Invoice: The bill you send to the customer requesting payment.
• Credit Note: A document issued to reduce an invoice amount due to returns or adjustments.
• Aging Report: A report that groups unpaid invoices by how long they have been outstanding (e.g., 0-30 days, 31-60 days, 61-90 days, 90+ days).
• Days Sales Outstanding (DSO): The average number of days it takes to collect payment after a sale. Lower DSO means healthier cash flow.
• Bad Debt: An invoice that is unlikely to ever be paid. In Canada, you can claim a bad debt deduction on your GST/HST return and income tax return, but you need to write it off properly.

Setting Up an Effective AR Process: From Invoice to Payment

A reliable AR process starts before you send the first invoice. If you do not define your terms and procedures upfront, you will chase payments forever. Here is a step-by-step framework adapted for Canadian small business owners.

Step 1: Define Your Payment Terms

Be specific about when payment is due. Common terms in Canada are net 30, but many businesses shorten to net 15 or even due on receipt for smaller amounts. Include late payment penalties. For example, you might charge 1.5% per month on overdue balances (18% annually). Note that provincial interest laws vary, so check your province's rate limits.

Step 2: Create Professional Invoices

Your invoice must include your business name, address, GST/HST registration number (if applicable), the customer's name and address, a unique invoice number, the date, a description of goods or services, the amount, the tax charged, and the total due. For Quebec customers, you also need your QST number and the customer's QST number if they are a registrant. A clear invoice reduces disputes and speeds up payment.

Step 3: Send Invoices Promptly

Do not wait until the end of the month. Send the invoice immediately upon delivery of goods or completion of services. The sooner the invoice arrives, the sooner the customer can process it. For recurring invoices, set up a schedule.

Step 4: Track Payments and Follow Up

Use an accounting system to record when you send invoices and when payments arrive. Run an aging report weekly. When an invoice approaches its due date, send a friendly reminder. If it becomes overdue, escalate: a phone call after 7 days overdue, a formal demand letter after 30 days, and then consider collections or small claims court after 60-90 days. Remember that in Canada, you can add interest and collections costs to the amount owed if your terms allow.

Step 5: Reconcile Payments to Invoices

When a payment arrives, match it to the correct invoice(s). If the customer pays short (e.g., deducts a discount without authorization), resolve the discrepancy. This step is where many businesses slip, leading to misapplied cash and inaccurate aging reports.

Managing GST/HST and Other Taxes in Your AR Workflow

Canadian sales taxes add complexity to accounts receivable. You must track which rate applies to each sale: 5% GST in Alberta, 13% HST in Ontario, 15% HST in Nova Scotia, 5% GST plus 9.975% QST in Quebec, or 5% GST plus PST in BC, Saskatchewan, and Manitoba. If you sell to customers in different provinces, your invoicing system must handle multiple rates.

Tax on Credit Notes and Adjustments

If you issue a credit note or refund, you must adjust the tax accordingly. For example, if you refund a $100 sale that had $13 HST, you issue a credit note for $100 plus $13 HST, reducing both your revenue and your HST remittance. Keep clear records of these adjustments because the CRA may ask.

When to Collect Tax

You must charge GST/HST on most sales to Canadian customers unless the customer provides a valid exemption certificate (e.g., for supplies to status Indians, agricultural goods, or medical devices). If you are a small supplier (revenue under $30,000 in a quarter), you do not have to register or charge GST/HST, but you may choose to voluntarily register. Once you register, you must charge tax on all taxable sales and remit it.

Input Tax Credits (ITCs) and AR

When you pay an invoice from a supplier that includes GST/HST, you can claim an input tax credit (ITC) on your GST/HST return. But if you are using the quick method, your ITCs are limited. The key point for AR: you need to track which invoices you have paid to claim ITCs timely. A good AR system helps you manage both sides.

Common AR Challenges Canadian Business Owners Face and How to Avoid Them

Challenge 1: Slow Payments and Cash Flow Gaps

Many small businesses operate on thin margins. Waiting 45 days for payment strains cash flow. To combat this, consider offering a small discount for early payment (e.g., 2% off if paid within 10 days, net 30). Or require a deposit before starting work. For ongoing contracts, bill monthly rather than waiting until the project ends.

Challenge 2: GST/HST Mismatch When Clients Pay Late

You invoice a client in March for $1,000 plus $130 HST. The client pays in June. You must remit the $130 HST to the CRA by April 30 (if quarterly filer). So you pay tax on income you have not yet received. To manage this, maintain a cash reserve or use a line of credit. Alternatively, consider using the quick method of accounting, which lets you remit a lower percentage of your taxable sales (but you cannot claim ITCs).

Challenge 3: Mixing Personal and Business Payments

If your business is a sole proprietorship, it is tempting to use personal accounts for business. But that makes AR tracking impossible. Open a dedicated business bank account and use a separate credit card for business expenses. For AR, use a business invoicing tool that integrates with your bank account.

Challenge 4: Not Using an Aging Report

You cannot manage what you do not measure. An aging report shows exactly who owes you money and how old the debt is. Review it weekly. Flag customers who consistently pay late and adjust their terms accordingly. For example, you might require prepayment from a customer who has paid 60 days late three times.

How to Automate Accounts Receivable (and Why It Matters)

Manual AR processes are error-prone and time-consuming. Automation reduces the risk of missed follow-ups, incorrect tax calculations, and delayed payments. A good accounting platform like Awditify can handle the heavy lifting.

What Automation Looks Like

• Automatic invoicing: Create recurring invoices for regular clients and send them via email automatically.
• Payment reminders: Set up automatic email reminders before and after due dates.
• Bank feed integration: When a payment arrives, the system matches it to the invoice, reducing manual reconciliation.
• AI categorization: Awditify uses AI to classify transactions, so you do not have to code each deposit manually.
• Real-time aging reports: See your AR dashboard updated instantly.
• E-signature on invoices: If you need client approval, Awditify allows e-signatures within the platform.

Manual vs. Automated AR: A Comparison

Real-World Scenario: A 12-Person Contractor Firm in Ontario

Consider a construction firm in Ontario with 12 employees. They send 30-40 invoices per month, each with HST at 13%. Before automation, the owner spent 8 hours per week on AR: creating invoices, tracking payments, and following up. With Awditify, they set up recurring invoices for regular clients and use the bank feed to match payments. The system automatically generates aging reports and sends reminders. The owner now spends 2 hours per week on AR and reduced DSO from 45 to 28 days. The time saved allows them to focus on bidding new contracts.

When to Escalate: Handling Late Payments and Bad Debts

Despite your best efforts, some customers will not pay. You have a few options in Canada. Start with a polite phone call. If that fails, send a formal demand letter with a clear deadline. If still unpaid, you can file a small claims court case (up to $35,000 in most provinces). Many provinces have simplified procedures for small businesses. Alternatively, use a collection agency, but they take a percentage (typically 25-50% of the amount collected).

Writing Off Bad Debts

If you determine a debt is uncollectible, you can write it off. For GST/HST purposes, you can claim a bad debt deduction on your GST/HST return, reducing the tax you owe. For income tax, you deduct the bad debt as a business expense. To do this, you must have included the amount in your taxable income previously. Keep documentation: the invoice, collection attempts, and a note explaining why you believe it is uncollectible.

Preventing Bad Debts

Screen new customers before extending credit. Check their payment history with other suppliers. For large orders, ask for a deposit or progress payments. Use contracts that allow you to charge interest and collection costs. If a customer has a history of slow pay, shorten their terms or require prepayment.
