Ecommerce and Online Business Accounting For Canadian Businesses

Ecommerce accounting tracks every dollar across your sales channels, revenue, platform fees, payment processing, COGS, refunds, and ad spend, so you see true profit. Most bookkeepers treat ecommerce like any other business. We don’t. We understand multi-channel payouts, FBA fees, Shopify settlements, GST/HST place-of-supply rules, and how to track landed costs in CAD for imported inventory.

What Makes Ledger Labs the Best Ecommerce Accounting Service in Canada?

See Your Real Profit, Channel by Channel

We reconcile bank deposits against true sales, strip out platform and gateway fees, and track COGS by SKU -so you know actual profitability by channel, not just topline revenue.

GST/HST and Provincial Sales Tax, Handled

Canadian ecommerce tax depends on where your customer is, not where you are. We manage GST/HST and PST/QST/RST on place-of-supply rules across every province, handle registration once you pass the $30,000 threshold, and keep your filings on time.

Marketplace Facilitator Rules, Decoded

Since 2021, marketplaces like Amazon have collected and remitted GST/HST on many third-party sales. We untangle what the platform handles versus what you still owe -so you don't double-remit or under-report.

Inventory and Landed Cost Done Right

We value inventory on a Canada-compliant basis (FIFO or weighted-average -never LIFO) and build duties, customs, and CAD landed cost into your COGS, so margins reflect reality.

Cross-Border Without the Headaches

Importing stock or selling into the US adds GST-on-imports, CARM obligations, US nexus exposure, and multi-currency complexity. We build it all into your books so cross-border growth doesn't create a compliance mess.

Fast, Real-Time Financial Visibility

No more 30–45-day closes or mystery ad spend ROI. You get a quick month-end close and live dashboards showing cash position, channel profitability, and marketing return.

Typical Ecommerce Accounting Problems We've Solved for Canadian Sellers

Over the years, we’ve met many ecommerce brands facing the same issues behind the scenes and helped them regain control when the finances got messy. Most bookkeepers make the same critical ecommerce mistakes, and they cost you thousands: recording bank deposits as revenue, expensing inventory when purchased, missing GST/HST obligations across provinces, not tracking COGS by SKU, ignoring payment gateway fees, and mixing business with personal expenses.

The worst part? Most owners don’t know these problems exist until tax season hits or they try to raise funding. If you’re nodding at any of these, you’re not alone.

Common Problems We Solve:

Month-end close dragging 30–45 days
20–30 hours a month lost to bookkeeping
Tax-season chaos and worry about CRA audits
Payment processor fees are quietly eating margins
Bank deposits that don't match sales reports across channels
Uncertainty about GST/HST registration and provincial sales tax
No visibility into true product profitability; COGS wrong or missing
Marketplace facilitator confusion (what Amazon remits vs. what you owe)

When to Bring in Ecommerce Accounting Support

You’ve crossed (or are about to cross) $30,000 in sales:
That’s the GST/HST registration threshold. Once you’re near it, registration, tracking, and provincial sales tax stop being optional -and getting them right from the start avoids penalties later.

You’re selling across multiple provinces:
Place-of-supply rules mean a sale to Ontario, BC, Alberta, and Quebec can each carry a different tax. We make sure you charge, collect, and remit the right amount everywhere your customers are.

You’re on more than one channel:
Amazon, Shopify, Walmart, eBay, and your own site all settle differently. When reconciling them by hand eats your evenings, it’s time to consolidate into one clean set of books.

You’re importing inventory or selling into the US:
Duties, GST on imports, CARM, US nexus, and multi-currency all complicate the picture fast. We build them into your accounting, so cross-border doesn’t become a liability.

Your close takes weeks, and your margins are a mystery:
If the month-end drags 30–45 days and you can’t say which products or channels actually make money, you’re flying blind. We deliver fast closes and SKU-level profitability.

In ecommerce, small errors compound across thousands of transactions. The earlier your books, sales tax, and inventory are handled properly, the more profit you keep and the faster you can scale.
