My accountant is connected, he has everything he needs.

My PEPPOL-certified digital invoicing, made simple:

  • I create an invoice, with or without pricing, with or without items.

    • Invoice with my logo, a nice and modern design.

    • My invoice is sent to my client via the official European PEPPOL network (mandatory as of January 1, 2026) and by email for individuals.

  • I receive my supplier invoices through the official PEPPOL network.

    • I can view them anytime.

    • I can easily make the payment.

  • My accountant automatically receives all sales and purchase invoices.

I’m ultra mobile:

  • My Invoice works on PC and smartphone. An iOS (iPhone) or Android app can be downloaded.
  • I take a photo with my smartphone of my expense receipts or restaurant bills.

I’m starting out, evolving within the software:

  • Import your customer list via an Excel file to get started faster.
  • Enter your rates to be more efficient, and create invoice templates you can reuse anytime.
  • Credit notes can be created based on an invoice or directly.
  • Easily pay a supplier invoice with your smartphone and banking app using a QR code.

I analyze my activity:

  • Simple and dynamic charts show your billed revenue and expenses.
  • I know exactly where I stand — no blah blah.

I protect myself from hacking:

  • Against hackers: your clients’ and suppliers’ VAT codes are automatically verified on official European Union websites.
  • Against phishing: your suppliers’ IBAN bank accounts trigger an alert if they have changed since the previous invoice.

I want to customize:

  • Easy customization of your invoice layout.
  • Easy import of your data via an Excel sheet.

I’M GROWING,
I’M GOING FURTHER:

  • Upgrade your subscription to “My Business” to manage your quotes and orders.
  • Track your working time on orders directly from your smartphone.
  • Invoice your orders.
  • With the PONTO link, instantly see whether your invoices have been paid.
