What does Popapi do?

Popapi is an e-commerce invoicing tool designed for European businesses. It generates XML invoices and sends them directly to national exchange systems and tax authorities such as Italy's SdI and the Pan-European Peppol network. The goal is to reduce errors and save time on compliance.

It works as a plugin for WooCommerce and Shopify, and also integrates with WordPress. You set it up in minutes, configure tax information, and choose a plan. The tool automatically creates structured XML invoices when customers place orders and transmits them to the required networks. It also collects invoicing data at checkout, validates VAT numbers, and handles credit notes within the same workflow. For automation, it offers webhook delivery to connect with ERP and back-office systems.

Popapi is for e-commerce store owners, accountants, and anyone managing invoices across multiple European countries. It simplifies compliance with different national standards without managing each system separately. The free plan covers basic XML generation and checkout fields, while paid plans add transmission, credit notes, and VAT validation.
