For ecommerce we lift the weight on inventory and multichannel integrations, since the work is reconciling marketplace payouts to orders and tracking cost of goods, not typing invoices. See the full rubric →

Xero
Best for ecommerce overall
Xero is the favorite of ecommerce bookkeepers because it pairs tidy inventory with the cleanest bank reconciliation, and it connects to A2X to turn Shopify and Amazon payouts into accurate journal entries. Unlimited users come on every plan. Multi currency, which most cross border sellers need, sits on the Established tier.
For a US store, QuickBooks Online brings the deepest reporting and the sales tax engine most accountants expect, plus inventory and commerce connectors. Inventory tracking lives on the Plus tier, so plan for that cost. It is the safest choice when you will hire a US accountant who works in QuickBooks daily.
A high volume or omnichannel brand running its own warehouse can unify inventory, orders and the ledger in NetSuite, with SuiteCommerce and strong stock control built for scale. It removes the connector patchwork. The base platform, per user fees and a real implementation budget make it a serious commitment.
Zoho Books bundles inventory and sales tax at a price that undercuts the leaders, and it plugs into the wider Zoho commerce and inventory tools for multichannel sellers. A free tier under fifty thousand dollars helps early stores. The deepest value assumes you live in the Zoho ecosystem.
A brand scaling past a single ledger gets multi entity finance and dimensional reporting from Sage Intacct, with inventory through its order and stock modules. It bridges the gap below full ERP. The price and setup only make sense once you have a finance team and real volume to justify them.
For a tiny shop or a side hustle, Wave keeps the books for free with real double entry and invoicing, which is enough before volume arrives. It is the lowest cost starting point. There is no inventory tracking and no marketplace connectors, so you will outgrow it as soon as orders and stock pick up.
