Your Store Runs 24/7.
Your Books Should Too.
Shopify, WooCommerce, Amazon, Etsy — running an e-commerce business in Canada means thousands of transactions, multi-province tax rules, and payment processor reconciliation that never stops. MaxRefund handles your books, GST/HST, and taxes entirely online so you can focus on growing your store.
What E-Commerce Owners Deal With
High Transaction Volumes
A store processing 500 orders per month generates thousands of line items across platforms, payment processors, refunds, and chargebacks. Manual reconciliation is unsustainable. We automate the feeds and reconcile every transaction — so your books close cleanly every month regardless of volume.
Multi-Province GST/HST
When you ship to customers across Canada, the place-of-supply rules determine which tax rate applies: 5% in Alberta, 13% in Ontario, 15% in Nova Scotia, 14.975% in Quebec. Applying the wrong rate on thousands of orders creates real CRA exposure. We ensure every sale is taxed correctly at source.
Payment Processor Reconciliation
Shopify Payments, Stripe, PayPal, and Amazon each settle on different cycles, net fees before depositing, and issue 1099/T4A-style reports in different formats. Matching deposits to orders to fees is one of the most time-consuming tasks in e-commerce accounting — and the most error-prone if done manually.

E-Commerce Questions — Answered
Yes. Once your total Canadian revenue exceeds $30,000 in any rolling 12-month period, GST/HST registration is mandatory. The rate you charge depends on where your customer is located, not where you are: 5% in Alberta and BC (GST only), 13% in Ontario, 15% in Nova Scotia, New Brunswick, PEI, and Newfoundland, and 14.975% for customers in Quebec (GST + QST). Shopify can be configured to apply the correct rate automatically — we help you set this up correctly from the start.
We consolidate all your sales channels into a single, clean set of books. Whether you sell on Shopify, Amazon Canada, Etsy, or your own website, each platform's transactions, fees, refunds, and settlement reports are imported and reconciled against your bank and payment processor statements. The result is one accurate picture of your business, not five fragmented spreadsheets.
Yes. Shipping costs to customers, packaging materials, product photography, Amazon and Meta advertising fees, Shopify subscription fees, and warehouse or storage costs are all deductible business expenses. Shipping costs paid by customers and reimbursed to you count as revenue — the matching outbound shipping cost is then deducted. We track these throughout the year so your deductions are complete and documented at filing time.
Payment processors like Stripe, PayPal, and Shopify Payments deposit net amounts — after deducting their fees — and on different settlement schedules than your actual order dates. We reconcile every deposit back to individual orders, separate the fees, match everything to your bank statement, and record it all correctly in your books. This eliminates the most common source of errors in e-commerce accounting.
Incorporation becomes financially attractive when your net profit consistently exceeds $80,000–$100,000 per year. At that point, the federal Small Business Deduction drops your corporate tax rate to 9% on the first $500,000 of active business income — well below the top personal marginal rate. Below that threshold, the added cost of corporate accounting, T2 filing, and record-keeping often outweighs the tax savings. We maintain clean books for both structures and can help you model the numbers when the time is right.
