Invoices & e-invoicing

Invoicing software — Write invoices — fast, correct, e-invoice ready.

B2B e-invoicing (XRechnung / ZUGFeRD) is mandatory in Germany from 2025. We build invoicing that handles this from day one.

For freelancers, SMEs and agencies invoicing from their desk.

What we hear every day

Do you know these problems?

Word or Excel invoices — manual, error-prone, no number sequences

Accountant prefers structured data over PDFs

No automatic reminders, no payment reconciliation

What your MVP can do

Typical building blocks for Invoicing software.

You pick the blocks that really matter for your first version. We build the rest package by package, with the development capacity of your chosen package.

Why web?

Invoices are rarely created on the road — almost always at a desk. A web invoicing tool is the right choice here.

  • Quote → order → invoice → credit note in one flow
  • XRechnung (BT standard) and ZUGFeRD PDF out of the box
  • Number sequences, recurring invoices and partial invoices
  • Dunning with reminder stages and interest
  • Bank integration for payment reconciliation
  • Tax keys, reverse charge, OSS for EU business
  • Accounting export and compliant archival
  • Multi-tenant for multi-company setups
