Outsourcing your accounting is a big move—especially in eCommerce, where the pace is relentless, the data is fragmented, and every percentage point in margin counts. You’re not just hiring someone to manage books. You’re trusting them to give you visibility, help you avoid tax trouble, and support smarter business decisions. That’s a pretty enormous responsibility. The wrong accountant will slow you down or leave gaps. The right one will quietly become one of the most valuable parts of your back office.
One of the first things to check is whether they truly understand platform mechanics. Not just how to read Amazon or Shopify’s dashboard—but how to reconcile what Shopify says you earned with what actually hit your bank account via Stripe or PayPal. Many generalist accountants miss the nuance of marketplace fees, delayed payouts, chargebacks, and returns that distort your actual numbers. A true eCommerce specialist accountant knows how to cleanly reconcile all those moving parts.
Inventory and cost of goods sold (COGS) are where many inexperienced firms slip. Your margins are only as accurate as your inventory valuation and COGS tracking. If those are off, you’re making decisions based on fiction. An accountant with eCommerce experience will know how to calculate landed cost, manage inventory flows across 3PLs, and show you product-level profitability with confidence. They should also understand how tools like inventory apps or ERPs feed into your accounting system and where manual errors tend to creep in.
Sales tax is another silent killer. With marketplace nexus laws constantly evolving, you might owe taxes in more states than you realize. An e-commerce tax accountant should understand multi-state tax obligations, how platforms handle collections, and when you need tools like TaxJar or Avalara. More importantly, they’ll make sure you’re not sitting on unpaid liabilities or misreporting collected tax as income.
Speed and clarity matter. Founders can’t afford to wait weeks for basic answers. You need real-time reporting—or close to it—especially when you’re running ad campaigns, managing inventory restocks, and making high-stakes pricing decisions. A great accountant will set up tools and dashboards that let you track:
- Channel-level profitability
- Product or SKU margins
- Ad spend vs. revenue returns
- Real-time cash flow
- Refund and return impact on earnings
These aren’t bonus features—they’re must-haves for any business making real decisions off financial data.
It’s also important to pay attention to how the accountant communicates. Are they just delivering numbers? Or are they asking smart questions about your business? The best outsourced accountants behave like internal team members. They notice things. They flag inconsistencies before they become problems. They explain—not just report. You should feel like you’ve gained a financial ally, not a spreadsheet vendor.
Equally important is experience at your level of complexity. An accountant who’s only worked with freelancers or local businesses probably hasn’t handled multi-channel, high-velocity transactions. Look for a firm that has supported Shopify sellers, Amazon FBA brands, or DTC stores doing $1M+ in annual revenue. Bonus points if they’ve worked through scaling phases, international expansion, or fundraising.
Because in eCommerce, the financial challenges aren’t theoretical—they’re right there in your returns, your inventory log, your ad account, and your cash flow. You don’t need a bookkeeper who’s figuring it out as they go. You need someone who’s already built systems that work—and knows how to fix them when they break.
