Why ecommerce breaks generic accounting tools
Selling physical goods online creates accounting complexity that service businesses do not face. The transaction volume is higher. Each platform (Shopify, Amazon, Etsy, eBay) deposits net amounts after fees, refunds, and chargebacks, and reconstructing the gross sales, fees, refunds, and tax components from a single deposit is genuinely hard without tooling. Multi-currency adds foreign exchange gain/loss accounting at month end. Sales tax adds nexus tracking and state filings.
The result is that the choice of accounting tool for ecommerce is much more about integration depth than about the accounting software itself. Two sellers with identical revenue can have completely different setups depending on where they sell, what currencies they bill in, and whether they hold inventory.
The integration layer
Sitting between your sales platform and your accounting software is the integration layer. The four main players in this space are A2X (the dominant tool for Shopify and Amazon, works with Xero and QuickBooks), LinkMyBooks (UK-strong, expanding US), Synder (broader sales-channel coverage), and Bookkeep (Shopify-focused). For most US sellers on Shopify or Amazon, A2X is the default choice.
What A2X-class tools do is summarise platform payouts into accountant-readable journal entries. Instead of seeing a single $4,200 deposit from Shopify on March 15, you see $5,800 in gross sales, $400 in refunds, $180 in payment processing fees, and $1,020 in sales tax collected. That is what your accountant needs to see for accurate books and tax filings.
Candidate tools, ordered by ecommerce fit
Candidate 1
Xero + A2X
Xero $20-50/mo plus A2X $20-200/mo depending on volume
$50-150/moLast verified April 2026
Best for: Multi-channel sellers, multi-currency, international expansion
The strongest combination for ecommerce sellers operating across channels and currencies. Xero handles multi-currency natively at a low tier and the global accountant network is large. A2X sits between Shopify or Amazon and Xero, summarising payouts into clean journal entries that match the actual deposit, separating sales, fees, refunds, and chargebacks. The result is books that reconcile cleanly without manual transaction-by-transaction entry.
Strengths
Strongest multi-currency support in the candidate set
A2X integration is the gold standard for Shopify and Amazon accounting
Large global accountant network

Trade-offs
A2X adds meaningful cost on top of Xero
Smaller US accountant network than QuickBooks
Setup is more complex than single-vendor solutions
QBO Plus $50-150/mo plus Shopify or A2X integration
$50-150/moLast verified April 2026
Best for: US-focused single or dual channel sellers
QuickBooks is the dominant US small-business accounting tool and has multiple integrations into Shopify and Amazon. The native Shopify connector is acceptable for single-channel single-currency operations. For multi-channel or higher volume, pairing QBO with A2X (yes, A2X works with QuickBooks too) is usually cleaner. Multi-currency is included from the Essentials tier upward. Sales tax automation is the strongest in the category.
Best for: Small to mid sellers already in the Zoho ecosystem
If you already use Zoho CRM, Zoho Inventory, or Zoho's broader stack, Zoho Books integrates tightly into the rest of your tools. The price point is aggressive across all tiers. Multi-currency is included at moderate tiers. The trade-off is that Zoho's US accountant network is smaller and the integration ecosystem with non-Zoho ecommerce tools (third-party Shopify connectors, A2X for Zoho) is thinner.
Best for: Single-channel single-currency micro-sellers
Wave is acceptable for very small ecommerce operations selling on a single platform in a single currency, with a US or Canadian bank. For anything beyond that scope (multi-channel, multi-currency, inventory, international banking) it breaks. The free price point makes it tempting but the migration cost when you outgrow it is the most common Wave-related expense ecommerce sellers encounter.
Multi-currency support means three things. First, you can invoice clients in their local currency. Second, you can record payments in that currency. Third, the software handles the conversion to your home currency for reporting, with foreign exchange gain or loss recognised at month end (the difference between the rate when invoiced and the rate when paid).
Xero handles this natively from a low tier. QuickBooks Online adds it at the Essentials tier and above. Zoho Books has it at moderate tiers. Wave does not really support multi-currency, full stop, because Wave's bank feeds are US and Canada only. If you are billing any international clients, Wave is not on your candidate list.
The non-obvious cost of multi-currency is the FX gain/loss reconciliation at month end. Some tools (Xero) automate this cleanly. Others require manual journal entries every month. For high-volume international sellers this is a real bookkeeper time sink and a reason to weight Xero more heavily.
Sales tax automation
Since the Supreme Court's 2018 Wayfair decision, ecommerce sellers can owe sales tax in any state where they have economic nexus, which is typically more than $100,000 of sales or 200 transactions in a calendar year. Tracking this manually across forty states is not realistic for an active seller. Automation tools (Avalara, TaxJar) handle the calculation, filing, and remittance.
QuickBooks has the strongest built-in sales tax handling among the major accounting tools. Xero typically pairs with Avalara or TaxJar. Smaller tools (Zoho Books, Wave) have weaker native sales tax handling and rely on third-party integrations. For US ecommerce sellers with multi-state nexus, sales tax automation is essentially mandatory once you are above the entry tier.
Inventory tracking
Inventory matters when you stock physical goods and want accurate cost of goods sold (COGS). The accounting consequence of not tracking inventory is that COGS is wrong, which makes gross margin wrong, which makes profitability analysis wrong. The IRS also requires inventory accounting for businesses above $25 million revenue and many businesses below that threshold benefit from doing it correctly anyway.
QuickBooks Plus has solid inventory built in. Xero has it natively but less depthful. For higher volume sellers, dedicated inventory tools (Cin7, Dear, Katana) integrate with QuickBooks or Xero and handle multi-location, kitting, and assembly more cleanly than the accounting software's built-in module. Below 500 SKUs the built-in modules are usually enough.
Dropshippers do not need inventory tracking. The supplier ships, you never hold stock, and your COGS is just the cost paid to the supplier per order. A2X-class tools handle this cleanly without needing inventory tracking on top.
Decision flow
The honest decision flow for ecommerce is roughly:
Single channel, single currency, USD only, low volume: Wave, or Zoho Books Free if outside the US/Canada.
Single channel, single currency, growing: QuickBooks + native Shopify connector or Zoho Books.

Frequently asked
Questions buyers ask
Why does generic accounting software fail ecommerce?+
Three things break. First, the sheer transaction volume of an ecommerce store overwhelms manual reconciliation. Second, the difference between gross sales, refunds, fees, and net deposit needs to be split into separate accounts and most generic tools do not do this without an integration. Third, multi-channel selling (Shopify and Amazon and Etsy) creates timing differences between when revenue is recognised and when the deposit lands. Without an integration like A2X, the books drift quickly out of reality.
What is A2X and do I need it?+
A2X is the dominant integration tool for Shopify and Amazon sellers using either Xero or QuickBooks. It pulls payout data from the sales platform, splits it into sales, fees, refunds, taxes, and adjustments, and posts a single clean journal entry that matches the actual deposit. The result is reconciliation that takes minutes rather than hours. For a Shopify or Amazon seller doing more than $10,000 a month in sales, A2X almost always pays for itself in saved bookkeeper time. Below that, manual entry is workable.
How does sales tax automation work?+
Sales tax automation calculates the correct tax rate for each transaction based on the buyer's location and the seller's nexus, tracks where you have nexus (the threshold for owing sales tax in a state), files returns, and remits the tax. The two big providers are Avalara and TaxJar. QuickBooks has built-in sales tax handling that is acceptable for US-focused sellers. Xero typically pairs with Avalara or TaxJar for the same job. The complexity comes from the Wayfair decision (2018) which lowered the bar for out-of-state sales tax obligations.
Do I need inventory tracking?+
Yes if you sell physical goods you stock and want accurate cost of goods sold and gross margins. No if you dropship (the supplier ships and you never hold inventory). Inventory tracking records what you bought, what you sold, what you have on hand, and the cost when sold. Without it, your cost of goods sold is inaccurate and your gross margin numbers are misleading. QuickBooks Plus and above has inventory built in. Xero has it natively. For higher volume, integrating with a dedicated inventory tool (Cin7, Dear, Katana) usually beats relying on the accounting software's module.
What about international VAT and GST?+
If you sell to customers in the UK, EU, Canada, or Australia, VAT and GST handling become real concerns. The thresholds for registration vary by country and are below the typical Wayfair-equivalent state threshold in the US. International sellers often pair Xero (which has stronger native VAT support than QuickBooks Online) with country-specific tax services. Specialist tax services like Avalara handle international VAT and GST registration and filing.
Can I just track everything in Shopify?+
Shopify reports are fine for a quick check on store performance. They are not accounting. Shopify does not produce a P&L that includes your non-Shopify expenses (rent, software, advertising, contractor payments), it does not produce a balance sheet, and it does not handle the tax filing forms your accountant needs. Use Shopify for store-level analytics, then push the data into accounting software for the actual books.
