Digitise your postal invoice mailing.

With Pingen you send invoices digitally and we take care of professional printing and dispatching via bpost – from 1,15 € per letter.

Get started

Faster payment

Stand out of the crowd by sending invoices by post. Physical invoices are more likely to capture your customers’ attention and encourage quick payment.

Show appreciation

As a company, you acknowledge your clients by investing time and money into postal invoicing. You strengthen customer relationships and loyalty.

Personal preference

Many people still prefer receiving invoices by post. Physical invoices provide a tangible, easy-to-file hard copy for archiving and record-keeping.

Avoid email chaos

Postal invoicing avoids issues like spam filters and overlooked emails, reducing the risk of missed invoices due to full inboxes or other email problems.

Send postal invoices, the Pingen way.

Forget printing, folding and mailing yourself. With Pingen, sending invoices by post is fully automated and handled via bpost.

Use existing invoices

Upload your PDF invoices through the WebApp, email, API or integration – we’ll print and send them for you.

Document validation

Pingen automatically validates your invoices and recipient addresses to ensure optimal print results and avoid cost for undeliverable letters.

Catch attention

Postal invoices show your business is professional and reliable. Unlike digital invoices, they get noticed by clients, feel more personal and help encourage faster payments.

Local print and delivery

We print and send locally via bpost – ensuring fast, reliable and environmentally friendly delivery across Belgium.
