Integrations for indirect tax

Connect the billing, commerce, and accounting tools you already use. Commenda calculates sales tax, value-added tax (VAT), and goods and services tax (GST) on every transaction.

Manage customer exemptions & certificates

Exempt customers stay exempt on every future transaction, with no manual flagging. During an audit the certificate is already on file and you save time.

Generate and file your returns

File without the prep work. Commenda turns your synced data into ready-to-file returns for every jurisdiction.

Flexible integrations, built for your setup

You decide what syncs, and we build around your system. Choose your countries and the transactions flow in.

Automate your indirect tax calculations

Get the right tax on every transaction, automatically. Commenda calculates sales tax, VAT, and GST the moment a sale happens. Rates apply per country, per state, and per product, so a digital service in Germany and a physical good in Texas are each handled correctly.

Sync your transactions, products, and customers

Your data flows into Commenda on its own. Commenda pulls transactions, products, and customers directly from your billing and accounting tools. Both payables and receivables sync at the transaction level, so nothing is missed and nothing is entered twice.

Track your global nexus exposure

Know where you owe before you cross the line. Commenda watches your sales against the thresholds in every market you sell to, and alerts you before you cross one, not the day after. You see it all in a single live exposure summary.

Consolidation

Commenda consolidates multiple integrations in one platform

Enterprise sellers run a storefront, marketplaces, a billing platform, and an ERP at once. Filing a return means collecting transactions from all of them, aggregating them, and then filing once. None of those platforms talk to each other. Commenda solves that.

Accounting systems do not talk to each other
Each platform's tax tooling reports only the transactions it processed. A storefront covers orders where you are the merchant of record. A marketplace covers what it facilitated. Your ERP holds invoices but cannot tell which orders a platform already taxed.
Exposure is never measured across systems
Economic nexus is assessed on your total sales into a state, not on one channel's share of them. Around 26 states count marketplace sales toward your threshold and about 20 exclude them (TaxJar), so the same marketplace revenue changes your position in one state and not the next. No single platform holds the figure that decision depends on.
Partial filings invite penalties
A state issues one permit per entity and expects one return covering every taxable sale into it that period. File on one channel's data and the return is wrong: direct sales, marketplace sales the platform already remitted, exempt wholesale revenue, and jurisdiction-specific shipping rules all have to reconcile. Understated returns draw penalties that have run 20% to 30% of the liability in cases we have cleaned up.
One ledger behind every channel
Every source connects to one ledger. Each transaction carries its origin, SKU, shipping amount, and any tax already collected, so platform-remitted revenue stays separate from revenue that still needs tax. The result is one exposure figure per state and one filing per period, with every line traceable back to the order it came from.
