How Do I Know If My Accountant Actually Understands E-Commerce?
Ask your accountant to explain how they reconcile Shopify payouts against actual sales, and how they handle Amazon's marketplace facilitator rules for Canadian GST/HST. If they look confused — or confident in the wrong answer — they're guessing.
The Problem: Most Accountants Have Never Seen a Shopify Payout File
A traditional accountant sees revenue as money landing in your bank account. That works fine for a plumber. It does not work for an e-commerce business.
Your Shopify payout isn't your revenue — it's your revenue minus fees, minus refunds, minus adjustments, deposited days after the sales actually occurred. Amazon is even messier: it bundles FBA fees, storage charges, reimbursements, and advertising credits into a single settlement that can span two different tax periods.
An accountant who doesn't know this will almost certainly overstate or understate your income, mistime your GST/HST remittances, and hand you financials that feel vaguely wrong even if you can't explain why.
Five Questions That Separate the Real From the Guesswork
These aren't trick questions. They're basic if you actually work in this space.
1. "How do you reconcile a Shopify payout to actual sales?" The right answer involves mapping the payout back to individual orders, accounting for the timing gap, and separating fees from gross revenue. "I import the bank deposit" is the wrong answer.
2. "How do you handle Amazon's bi-weekly settlement statements?" A real e-commerce accountant will mention that Amazon remits GST/HST as a marketplace facilitator on eligible sales — meaning you don't collect or remit that portion yourself — and that FBA fees paid to Amazon's Canadian entity have their own GST implications. Blank stares are a red flag.
3. "How do you track COGS when inventory moves between FBA warehouses and my own 3PL?" This is a multi-location inventory problem. The answer should include landed cost tracking, not just what you paid on the invoice.
4. "How do you treat the difference between a refund and a chargeback in the books?" They're not the same. A refund is a revenue reversal; a chargeback often involves a fee and a dispute window. Mixing them up distorts your true sales and margin picture.
5. "Can you show me a platform-level P&L — Shopify vs. Amazon vs. Etsy — separately?" If your accountant produces one blended income statement and calls it done, you have no idea which channel is actually profitable. That's not accounting; it's a number soup.
What the Right Answers Sound Like
You don't need your accountant to recite the answers verbatim. What you're listening for is fluency — the kind that comes from doing this dozens of times, not from Googling it the night before your call.
They should be able to talk about platform payout timing, marketplace facilitator rules under Canadian GST/HST, multi-platform fee structures, and channel-level margin without you having to explain what any of that means.
If you find yourself educating your accountant on how your business works, that's a signal worth taking seriously.
Why This Matters Beyond "Clean Books"
The real cost of an accountant who doesn't understand e-commerce isn't a messy balance sheet. It's the decisions you make based on financials that don't reflect reality.
You might cut your best-performing channel because the numbers make it look unprofitable. You might underpay or overpay GST/HST because the timing on marketplace remittances was handled wrong. You might miss input tax credits on platform fees you're paying in Canadian dollars to Canadian entities.
Multi-platform e-commerce reconciliation is a genuinely specialised skill. It's the kind of problem SGML Accounting was built to solve — not as a niche curiosity, but as the core of what we do for Canadian e-commerce owners every day.
The Short Version
You should not have to explain your business model to your accountant. If you do, the engagement isn't working in your favour.
Frequently asked questions
What's the biggest accounting mistake e-commerce accountants make with Shopify?
Treating Shopify payouts as revenue. The payout is a net settlement — it arrives after fees, refunds, and timing delays. Booking the deposit as revenue inflates or distorts your income and can throw off your GST/HST remittances.
Does my accountant need to know Amazon's marketplace facilitator rules for Canadian taxes?
Yes. Under Canadian GST/HST rules, Amazon acts as a marketplace facilitator for certain third-party sales, meaning Amazon collects and remits the tax — not you. An accountant who doesn't know this could have you double-remitting or misreporting your taxable sales.
Should my accountant give me separate P&Ls for each sales channel?
Absolutely. A blended P&L across Shopify, Amazon, and Etsy hides which channel is actually making you money after fees, shipping, and returns. Channel-level reporting is the minimum standard for making sound growth decisions.
How do I know if my current accountant's e-commerce mistakes are costing me money?
Start by asking for a breakdown of gross sales vs. net payouts by platform for one recent month. If your accountant can't produce it quickly — or the numbers don't reconcile to your platform dashboards — there's likely money leaking somewhere in the books.
Can a general accountant learn e-commerce accounting, or do I need a specialist?
A sharp generalist can learn it, but it takes time — and you're the one funding that education. Multi-platform reconciliation, marketplace tax rules, and inventory costing across fulfilment channels are specialised enough that an accountant already fluent in the space will cost you less in errors and missed opportunities than a generalist getting up to speed.
Every business's tax situation is different — platform rules, registration status, and filing obligations vary. Talk to a qualified accountant about what applies to yours.
