E-Invoicing & Physical Mail

E-Invoicing and Physical Mail, Built In

Send compliant electronic invoices over the Peppol network, or drop a printed invoice in the post, without leaving Invoice My Clients.

What is e-invoicing?

E-invoicing delivers a structured, machine-readable invoice directly into your customer’s accounting system through a regulated network rather than as a PDF attachment. Invoice My Clients connects to the Peppol and DBNA networks so your invoices arrive in the standard format buyers and tax authorities expect.

For clients who still want a paper copy, the same invoice can be printed and mailed for you, with address verification and delivery tracking, so every recipient gets the format they prefer.

  • Send invoices over the Peppol and DBNA e-invoicing networks.
  • Validate a recipient’s network participant ID before you send.
  • Track delivery status with network webhooks as it progresses.
  • Print and post a physical invoice with address verification.

Reach every client, every channel

From regulated electronic delivery to a stamped envelope, invoicing meets clients where they are.

Peppol & DBNA delivery

Send structured electronic invoices over the standards-based networks that businesses and governments rely on.

Global reach

Reach recipients across the growing list of regions and tax authorities that mandate e-invoicing.

Participant validation

Confirm a recipient is reachable on the network before sending, so invoices do not bounce.

Physical mail

Have a printed invoice produced and posted for you when a client prefers paper.

Delivery tracking

Follow the status of an e-invoice through network webhooks and of physical mail through its mailing lifecycle.

Address verification

Mailing addresses are checked before anything is printed, reducing returned mail.
