If you are an e-invoicing solution provider and want to integrate your solution with e-FACT, you need to follow the steps detailed in the e-FACT integration documentation

If during the integration process you have doubts or need any clarification in relation to the integration, you can transfer them to us through the Support to the integration form .

IMPORTANT: This information is for electronic invoicing solution providers. Public Administration suppliers do not need to integrate into the e-FACT service, as you can use the delivery box to deliver your electronic invoices. Learn more at How to invoice electronically if I'm a supplier.

In case the volume of invoices you manage is very high, you can integrate your tool with the e-FACT in order to automate the sending and receiving. Since AOC we recommend integration for companies or organizations with a volume of invoices to be generated for Public Administrations exceeding 100 monthly invoices.
