Why Sunday decided to use Invopop
In short
Sunday kept its own billing system and put Invopop behind it. PDF invoices now go out in four countries, Italy's e-invoicing format was met within weeks of opening there, and a country Invopop did not yet cover took a week to add.
What they achieved
- Integrated Invopop with Sunday's in-house billing with no major changes
- PDF invoices issued in France, Germany, the UK and the United States
- Opened in Italy and complied with the local e-invoice format within weeks
The case
Sunday, a payment solution for restaurants serving over 4,000 customers across five countries, sought an API to issue invoices in different countries as their transaction volumes scaled. Although they considered solutions like Stripe and Chargebee, they preferred to keep billing in-house and thus looked for a modular API invoicing solution.
We requested support for Germany when Invopop didn't have it. They launched it in a week
