eCommerce Bookkeeping Services for Ontario Sellers
AccTax helps Shopify, Amazon, Etsy, eBay, WooCommerce, and multi-channel sellers organize platform payouts, fees, inventory, GST/HST records, and tax-ready books.
A bank deposit is not the same as platform revenue
A Shopify payout and a bank deposit are rarely the same number, and that gap is where most seller bookkeeping goes wrong. The deposit already has fees, refunds, and processing charges subtracted before it lands, so the books need to separate revenue, refunds, and fees as three distinct entries, not one lump sum.
Every platform, product, and currency adds a new layer
Multi-platform reporting
Selling across more than one platform multiplies the problem. Shopify, Amazon, Etsy, and eBay each generate different report formats and different payout timing, and reconciling them the same way produces numbers that look organized but aren't accurate.
Inventory and COGS
Inventory adds a second layer entirely. Cost of goods sold and stock valuation directly shape what your actual profit looks like, and sellers who skip that tracking often discover at tax time that their reported margin has little to do with what they actually kept.
GST/HST registration timing
GST/HST registration timing catches sellers off guard too. Once taxable revenue crosses $30,000, registration is required, but the deadline depends on how you crossed it. Hit the threshold within a single quarter and registration is immediate. Cross it gradually across four quarters and the deadline shifts to the end of the following month instead.
USD and multi-currency sales
USD sales bring their own wrinkle. Revenue has to be reported in Canadian dollars, and CRA generally accepts conversion at the exchange rate on the transaction date, with certain average-rate methods accepted in specific circumstances, provided the method stays consistent year to year.
Keep the source records behind the numbers
CRA generally requires business records to be kept for six years from the end of the last tax year they relate to.

Cross-border legal matters and US state sales tax obligations fall outside that scope and generally need a specialized advisor familiar with the specific state or platform involved.
