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.

Swiss QR invoices

By sending Swiss QR invoices by postal mail on perforated paper, you enable customers to pay invoices even faster and more conveniently.

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.

No more printing, folding, stamping or trips to the post office. With Pingen, sending invoices by postal mail via Swiss Post is fully digital and automated.

Use existing invoices

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