E-Invoicing

Global e-invoicing compliance from a single integration

What is Fonoa E-Invoicing

Connect once and meet every mandate in 50+ countries, all from a single API. Fonoa E-invoicing turns fragmented global rules into one standard model so you can catch errors early and keep invoices moving.

Capabilities

Increase your markets, not your workload

Integrate once, add markets without limits

Use our single standard data model to standardize data inputs and expand into new markets with minimal effort.

Full visibility across every submission

Track every invoice in one place. Errors flagged, rejections logged, and resolutions triggered automatically to keep rejection rates low.

One input handles every local format

Submit transaction data once, and Fonoa translates and delivers it in the format each jurisdiction requires.

Accredited connections to tax authorities

Direct government connections in every mandated market, built for high throughput with automated retry logic.

AR and AP E-invoicing both covered

Validate, standardize, and submit outgoing invoices automatically. Receive, validate, and share incoming invoices from suppliers.

Connects to the rest of your tax stack

E-Invoicing shares one data model with the Fonoa platform. Invoice data flows directly into return preparation when Returns is connected.

How teams use E-Invoicing

Meeting a new mandate deadline

When a country you operate in introduces a new mandate, Fonoa absorbs the change. No rebuilding, no re-integration. Rules are kept current automatically as requirements evolve.

Faster market entry

When the business expands into a new jurisdiction with e-invoicing requirements, your team adds the market to an existing integration rather than starting a new project.

Keeping tax data current

Full integration with the Fonoa Platform

Keeping payments moving

When invoice rejections are causing cashflow delays, Fonoa catches errors before they reach the tax authority so invoices are accepted first time and payments stay on schedule.
