One of the first questions new eCommerce clients ask us is: "Should I use QuickBooks or Xero?" It's a fair question — both are excellent accounting platforms, both integrate with Amazon and Shopify via A2X, and both can produce the financial reports you need. But they're not identical, and the right choice depends on your specific situation.
Having set up hundreds of eCommerce accounting systems for sellers across Amazon, Shopify, eBay, and Etsy, here's our honest, hands-on comparison.
The Short Answer
If you're a US-based seller or primarily selling in the US market, QuickBooks Online is generally the better choice due to its superior US sales tax features and wider US accountant familiarity. If you're a UK, EU, or internationally focused seller, Xero edges ahead for its VAT handling, Making Tax Digital compliance, and multi-currency features.
If you're unsure, choose based on your accountant's preference — consistency matters more than the platform you use.

QuickBooks Online — Deep Dive
Strengths for eCommerce
- US Sales Tax Centre: QuickBooks has built-in nexus tracking, automated rate calculation, and can prepare multi-state sales tax returns directly — invaluable for US sellers navigating economic nexus obligations.
- Widespread US adoption: The vast majority of US-based accountants are QuickBooks certified, making it easier to find local professional support.
- Robust reporting templates: Dozens of pre-built reports including P&L, balance sheet, cash flow, and ageing reports available out of the box.
- Payroll integration: QuickBooks Payroll is tightly integrated for sellers with US employees.
Weaknesses for eCommerce
- Multi-currency requires the Plus plan ($85/mo) or higher — costly for international sellers
- Bank feeds can be unreliable with some international banks
- Interface is busier and less intuitive than Xero for new users
- Storage limits on lower plans can be restrictive for sellers with large transaction volumes

Strengths for eCommerce
- Multi-currency on all plans: Essential for sellers dealing in USD, GBP, EUR, AED, and PKR simultaneously. Xero handles currency conversion and revaluation automatically.
- Making Tax Digital native: Xero has had MTD-for-VAT compliance baked in since 2019. Direct HMRC API connection, no third-party bridging software required.
- Superior bank feeds: Xero's direct connections with banks are generally more reliable and auto-update more consistently.
- Unlimited users: Unlike QuickBooks, Xero doesn't charge by user — great for growing teams with VAs, bookkeepers, and accountants all needing access.
- Cleaner interface: Most new users find Xero's dashboard easier to navigate, especially for reviewing reports and reconciling transactions.
Weaknesses for eCommerce
- US sales tax features are basic — needs TaxJar or Avalara for multi-state compliance
- Fewer US-based accountants are Xero-certified (though this is changing)
- Early plan limits invoices to 20/month — fine for B2B but check if you send invoices
The A2X Factor: Why It Matters More Than Platform Choice
For Amazon and Shopify sellers, the most important factor isn't QuickBooks vs Xero — it's whether you're using A2X. A2X integrates equally well with both platforms and is the single most impactful tool for eCommerce bookkeeping accuracy. Without A2X (or equivalent), you're manually reconciling settlement reports — a process that takes hours and introduces significant error risk.
At TSA & COO, we use A2X with both QuickBooks and Xero clients. Our recommendation is always: set up A2X first, then choose the accounting platform that best fits your geography and accountant preference.
Our Recommendation by Seller Type
- US Amazon FBA seller, no international sales: QuickBooks Online Plus
- UK Amazon FBA or Shopify seller: Xero
- Multi-country seller (UK + US + EU): Xero (superior multi-currency)
- Pakistan-based seller with international operations: Xero or QuickBooks depending on primary market
- Etsy or eBay only, small volume: Either — Xero's Starter plan is slightly simpler
✓ Migration tip: If you're already on one platform and considering switching, think carefully. Migration is possible but involves exporting historical data and re-mapping accounts. Unless you have a strong reason to switch, it's usually better to optimise your current setup with proper A2X configuration and accounting structure.
