Sales tax and VAT software for Xero
Xero calculates sales tax on invoices in the states you tell it you are registered in, and reports on tax in one country. Registering, measuring your exposure, and filing US returns sit outside it. Commenda does those from the same Xero data, across all 50 states and 70+ countries.
Trusted by global businesses
Monitor your global exposure
Xero calculates in the states you selected at setup. Commenda measures the same invoices against thresholds in all 50 states and 70+ countries, including the ones you have not registered in yet.
Calculate tax before the invoice goes out
Tax is calculated per line item and written into the invoice while it is still a draft, so your team reviews it and sends it as normal. Anything that should not be taxed can be excluded.
File, remit, and post it back
Returns are built from your Xero data and filed on each jurisdiction's own frequency. The liability posts back to the ledger, with US sales tax and UK VAT routed to separate accounts.
Coverage comparison
What Commenda covers that Xero does not
Xero calculates sales tax on invoices and quotes, in the states you select. Everything around that calculation is a separate job, and these are the seven that matter. Xero's figures come from its Xero Central articles on sales tax in Xero and auto sales tax and the Sales tax report, plus its tax management FAQ, checked on July 29, 2026.

Calculate taxes globally on Xero using Commenda
Tax is calculated on every Xero invoice, line by line, using the product code and the customer's exemption status. One invoice can carry a taxable line and an exempt line, and each is handled correctly. Your team reviews the invoice in Xero before it goes out, and anything that should not be taxed can be excluded. Calculation only runs where you hold a registration, so you never collect in a state you are not registered in.
Track your global exposure from Xero
Xero calculates in the states you told it you are registered in. Commenda reads the same invoices and measures them everywhere you sold, registered or not, against thresholds in all 50 states and 70+ countries. Connecting Xero backfills your history, so exposure you already carry shows up next to today's invoices. Alerts fire at 80% of a threshold, before you cross.
Automatically remit transactions around the world
Returns are built from the same synced data, so nothing gets exported or re-keyed. Commenda files on each jurisdiction's own frequency, tracks remittance, and files amended returns where a period needs correcting. The liability posts back to your ledger with the filing confirmation attached, and US sales tax and UK VAT route to separate accounts rather than one line.
Manage your customers and exemptions in one place
Xero lets you mark a contact or an invoice as tax exempt. Commenda handles getting the certificate behind that flag. Your customers upload through a portal, each one is validated on upload and stored against the customer, and it applies automatically in the states where it is valid. Expiries are tracked and chased.
Consolidation
Commenda consolidates multiple integrations in one platform
A cross-border business runs Xero, a storefront, a billing platform, and often a marketplace. Filing one return means pulling transactions from all of them, reconciling what was already taxed, and filing once. Xero reports on one country. Commenda solves the rest.
Your ledger is not your only source of revenue
Xero's auto sales tax runs on invoices and quotes. For everything else, Xero states that if you import sales from another platform it does not automatically recalculate sales tax on those sales. Revenue arriving from a marketplace has often already been taxed by the facilitator. Revenue arriving from your own checkout has not. The ledger holds both and cannot tell them apart.
Thresholds are assessed on all of your sales
Xero's own nexus guide puts the economic threshold at over $100,000 of sales in many states and $500,000 in others, with transaction thresholds of 100 or 200 where they apply. All 45 states with a sales tax have adopted nexus rules for remote sellers and marketplaces. Those tests run on your total sales into a state. No single system holds that number.
One tax account cannot describe every jurisdiction
Xero documents that it uses one sales tax account to record all sales tax, independent of state or jurisdiction, and that rates posted to a second account drop out of the Sales tax report. Meanwhile five states levy no sales tax at all and home-rule jurisdictions in Alabama, Colorado, Idaho, Illinois, and Louisiana set their own. One account, many answers.
One ledger behind every channel
Every source connects to one ledger. Each transaction carries its origin, product code, and any tax already collected, so marketplace revenue stays separate from revenue that still needs tax. The result is one exposure figure per state, one return per period, and every line traceable back to the invoice it came from.
Cost of growth
What cross-border tax costs on top of Xero
Auto sales tax comes with every Xero subscription. The pieces a cross-border business needs sit outside it: multi-currency on a higher plan, automated US filing with Avalara, and a second organisation for a second tax country. Commenda is priced as a subscription that covers all of it.
| What you need | Where Xero puts it |
|---|---|
| Where auto sales tax is included | Every US subscription. Early is $25 a month, Growing $55, Established $90 |
| Where multi-currency starts | Excluded from Early and Growing. Included on Established only |
| Same split in the UK | Excluded from Ignite at £16 a month and Grow at £37. Included on Comprehensive at £50 and Ultimate at £65, all excluding VAT |
| Automated US filing | Not part of a Xero subscription. Customers sign up for it separately with Avalara |
| Entry-plan volume caps | 20 invoices and 5 bills on Early, and transactions initiated by app partners can count toward the invoice limit |
| Cost of a second tax country | A second Xero organisation. The country an organisation pays taxes in cannot be changed after it is created |

Frequently asked questions
No, and Xero says so itself: Xero doesn't file sales tax returns directly. What Xero does is produce a Sales tax report per state, which you mark as complete to track your filing periods, and record the payment against your sales tax liability. Automated US e-filing is a separate sign-up with Avalara. Commenda files the return instead, across all 50 states on each state's own frequency, tracks remittance per jurisdiction, and files amended returns where a period needs correcting. The UK is different: Xero submits VAT returns to HMRC itself.
No. Registration is the input. You tell Xero where you are already registered. Xero's documentation is explicit that to use its sales tax features your business must already be registered to collect in one or more states, and that setup asks you to select those states. Anything you sell into a state you did not select is calculated at zero. Commenda measures the same Xero invoices against economic and physical thresholds in all 50 states, every EU member state, and 70+ countries, and alerts you before you cross rather than after.
Yes. Tax is calculated while the invoice is still a draft and written straight into it in Xero, per line item, using the product code on each line and the customer's exemption status. Your team reviews the invoice and sends it as normal. Nothing goes out untaxed, and nothing goes out unreviewed.
Yes. Xero documents that it uses one sales tax account to record all sales tax, independent of state or jurisdiction, and that rates posted to a second account are excluded from the Sales tax report. Commenda routes multi-region tax types to separate accounts, so US sales tax and UK VAT do not aggregate into one line your finance team then has to unpick. Account routing is mapped against your chart of accounts during implementation.
Yes. Xero states that sales imported from another platform are not recalculated, and its auto sales tax covers invoices and quotes. So Commenda connects your other channels directly rather than relying on the Xero import. Native connectors cover NetSuite, QuickBooks, and Sage Intacct alongside Stripe, Chargebee, Recurly, and Zuora, and there is a REST API for a custom stack. Marketplace facilitator rules keep marketplace revenue separate from direct-channel revenue, so you are not filing on tax someone else already remitted.
Yes, with some scoping. Where data sits in a warehouse rather than a supported system, we work from structured exports or a custom data connection, with the right permissions on sensitive fields like customer location. We are explicit about what a custom source needs versus a native integration.
No. Your registrations, exposure history, product tax codes, and exemption certificates live in Commenda, so the compliance record survives the move. We have onboarded customers who connected Xero while a migration to a larger ERP was already planned, and scoped the second integration alongside the first. When the accounting system changes, the compliance record does not reset.
Custom integration support for your business
Every business runs its accounting differently, and those processes exist for good reasons. We map how yours works and build the integration to match, rather than asking you to work around ours.
Indirect Tax
Monitor nexus exposure, register, file, and remit sales tax and VAT in one platform. Commenda keeps you compliant across 100+ jurisdictions.
