eCommerce & Online Retail Accounting & CPA Services

Selling online opens up vast markets-but it also creates complex accounting challenges that traditional retailers don’t face. From cross-border tax obligations and marketplace facilitator compliance to inventory valuation across multiple warehouses and digital goods taxation, eCommerce businesses operate in a financial environment that demands specialized expertise. At Insight Accounting CPA Professional Corporation, we provide comprehensive accounting solutions for eCommerce and online retailers generating between $500,000 and $25 million in annual revenue across Ontario and beyond.

eCommerce-Specific Accounting Solutions

Cross-Border Tax & GST/HST Compliance

Selling across provincial and national borders creates layered tax obligations. We help eCommerce businesses understand their Canadian GST/HST registration requirements, US sales tax nexus thresholds, and VAT obligations in European markets. Our team structures your tax collection systems to ensure compliance while avoiding double taxation through proper use of treaties and registration strategies.

Marketplace Facilitator Compliance

The rise of Amazon, eBay, Etsy, and other marketplace platforms has transformed how online sellers manage tax compliance. Marketplace facilitator laws shift tax collection responsibility to the platform for certain transactions-but sellers remain responsible for their own income tax reporting, business registration requirements, and understanding when platform-collected taxes create obligations versus when they remain the seller’s responsibility. We navigate these complex arrangements to keep you compliant.

Digital Goods & Services Taxation

The taxation of digital products-including software, ebooks, online courses, and streaming services-varies by jurisdiction and continues evolving. We ensure your digital goods are properly classified for HST purposes, manage the distinction between taxable digital services and exempt educational content, and handle the specific rules around electronically supplied services to international customers.

Multi-Channel Inventory & Cost of Goods Sold

eCommerce businesses often sell through multiple channels-direct website, Amazon FBA, wholesale to retailers-each with different fulfillment costs and revenue recognition timing. We implement inventory tracking that supports your business model, whether you’re holding stock in Canadian warehouses, using Amazon FBA in multiple countries, or operating drop-ship arrangements. Accurate COGS tracking by channel helps you understand true profitability across your sales mix.

AI & Automation for eCommerce Accounting

The volume of transactions generated by eCommerce businesses-often thousands of sales per month across multiple platforms-makes manual accounting impractical. Our Accounting Intelligence platform leverages AI to fully automate the integration of data from Shopify, WooCommerce, Amazon Seller Central, Etsy, and dozens of other platforms directly into your accounting system.

Machine learning algorithms categorize transactions automatically, distinguishing between product sales, refunds, shipping income, and platform fees while matching them to appropriate general ledger accounts. AI-powered reconciliation compares platform payouts against bank deposits, instantly identifying discrepancies that require investigation. For businesses selling across borders, automation handles currency conversions using historical exchange rates and identifies transactions requiring special tax treatment.

Predictive analytics provide eCommerce sellers with powerful forecasting capabilities-projecting cash flow based on seasonal trends, identifying optimal inventory reorder points, and modeling the impact of promotional pricing on profitability. Natural language processing reads supplier invoices and automatically extracts line items, matching purchase orders to receipts and identifying pricing discrepancies without manual review.

The result is real-time financial visibility into your eCommerce operation. Instead of waiting weeks after month-end to understand performance, you have accurate financial data updated daily-enabling faster decisions about inventory investments, marketing spend, and pricing adjustments.

Frequently Asked Questions

Do I need to collect GST/HST on sales to customers in other provinces?
Generally, yes-if you’re registered for GST/HST, you must collect the appropriate tax rate based on the customer’s province of residence. We help eCommerce businesses manage multi-rate tax collection in their shopping carts and ensure proper remittance to CRA regardless of where your customers are located.

How do marketplace facilitator laws affect my tax obligations?
When selling through platforms like Amazon or eBay, the marketplace may collect and remit tax on your behalf for certain transactions-but you’re still responsible for income tax reporting and may have obligations for sales made outside the marketplace or for sales below facilitator thresholds. We clarify exactly what the platform handles versus what remains your responsibility.

What tax issues arise when selling digital products internationally?
Digital products sold to international customers have specific tax treatment depending on the destination country and the nature of the product. Some jurisdictions require VAT registration at relatively low revenue thresholds. We help identify where your international sales create tax obligations and structure compliance accordingly.

How do I calculate true profitability when selling through Amazon FBA?
Amazon FBA profitability requires understanding not just the obvious fees but also the hidden costs: storage fees, removal fees, long-term storage penalties, and referral fees that vary by category. We build detailed profitability models that show true contribution margins by product and help identify which SKUs are actually profitable after all costs.

Should I incorporate my eCommerce business or operate as a sole proprietor?
The right structure depends on your revenue level, risk exposure, and growth plans. Incorporation offers liability protection and potential tax advantages but comes with compliance costs. We analyze your specific situation to recommend the structure that maximizes after-tax income while considering exit planning and scalability.

How do drop-shipping arrangements affect my tax obligations?
Drop-shipping creates particular complexity because you may never touch the inventory you sell. Depending on your supplier’s location and your customer’s location, you may face different tax obligations than traditional inventory-holding retailers. We help drop-shippers understand their tax collection responsibilities and ensure proper reporting of these transactions.
