The invoicing infrastructure
for global businesses

E-invoicing is issuing and receiving invoices in a structured, machine-readable format that tax authorities and other software can process automatically, and in many countries reporting that data to the government, often through government-approved platforms, rather than emailing a PDF. A growing number of countries now mandate it. Invopop generates each country's required format, sends and receives invoices, and reports to the right tax authority for you in 30+ countries.

With e-invoicing, the government sets the format you must use to send invoices and requires a copy. With e-reporting, you invoice your customers in your own format, but the tax authority requires you to report some of that data, often in real time (for example, Spain's SII system). Many countries require one or both. Invopop supports e-invoicing and e-reporting, generating the required formats and filing the required reports with each tax authority.

Invopop is an e-invoicing, e-reporting, and tax-compliance API. It lets global companies and platforms send, receive, and report compliant invoices across 30+ countries from a single integration, with workflows you configure to match your own process. Invopop converts each invoice into the local legal format, files it with the right tax authority, and stays current as the rules change, so you never build or maintain it in every country you operate in.

An API is simply a way for two systems to connect and pass data automatically. With Invopop, your system sends each invoice in one standard format (called GOBL), and Invopop turns it into the exact format the destination country legally requires, sends it to the right tax authority or network, and returns a compliant invoice, so no one on your team has to learn or maintain each country's rules.

A growing number of countries now require e-invoicing or e-reporting, from Spain (VERI*FACTU), Italy (SdI), France, and Poland (KSeF) to Mexico (SAT), Saudi Arabia (ZATCA), and Colombia (DIAN), as governments move to close VAT gaps and get real-time visibility into transactions, with more added each year. Invopop supports e-invoicing and e-reporting in 30+ countries including the Peppol network, and maintains each connection so you stay compliant as the rules change. With Invopop as your single provider across every market, a new mandate never means a new vendor or integration, so your business stays future-proof.

There are two ways to use Invopop, depending on whether you invoice for yourself or for your customers. To invoice for your own business, connect Invopop to your billing or ERP, or build directly on our API. You can also offer compliant invoicing to your customers under your own brand by embedding Invopop in your product (white-label) through the API. Either way, set it up yourself with our developer docs, or our team can help.

Yes. Invopop connects to billing and ERP tools like Stripe, Chargebee, and NetSuite (with more coming soon), so invoices flow straight from the systems you already use, and you can build the workflows that best fit your processes. Invopop converts each invoice into the local legal format and sends it to the right tax authority or network automatically.

Yes. POS, ERP, marketplaces, and vertical SaaS embed Invopop through the API to offer compliant e-invoicing to their own customers under their own brand, onboarding customers programmatically and adding new countries without a separate build each time.

On average, implementation takes 3 to 6 weeks, depending on your setup. Because you work with one format (GOBL) and a single integration, adding each new country afterward is a configuration change, not a new build. You can start building and testing in the sandbox immediately, no sales call required.
