Service firms have an intake, not a goods problem
A trading business thinks of goods receipt and order reference with e-invoicing. A service firm does not have that. What it has: many small incoming invoices — software subscriptions, freelancers, cloud tools, subcontractors.
Precisely this multitude of small invoices is the stress point. Not one big supplier invoice a month, but thirty small ones from ten sources, often as XRechnung.
The ERP you don't have, you don't need either
Service firms often work with lean accounting and a tax advisor. Introducing an ERP to accept e-invoices would miss the point.
What counts is an orderly intake that collects the many small invoices, validates, approves and passes them on cleanly. The existing accounting stays — it just gets cleaner input.
Don't lose the project reference and reverse charge
Two things easily get lost with service firms: the assignment to the project and the correct treatment of EU services.
A cloud invoice from Ireland, a freelancer invoice from the EU — reverse charge wants to be detected cleanly. And internally every invoice wants to be assigned to the right project or customer, otherwise the calculation is off. A structured intake makes both traceable instead of leaving it to memory.
Approval that fits the working day
Consultants and agency people do not sit in the office sorting mail. They are at the client, in a meeting, on the road. An approval process that assumes a fixed desk gets ignored.
What makes sense is approval that works in between: check briefly, approve, move on. The process must adapt to the working style, not the other way round — otherwise the intake jams until month-end.
A lean changeover in practice
For most service firms this path is enough:
- A central invoice address for all intakes instead of scattered mailboxes.
- Automatic format detection so XRechnung, ZUGFeRD and PDF are handled correctly.
- Project or customer assignment already at intake, not only in accounting.
- Mobile, fast approval for on the road.
- Clean export to the existing accounting or tax advisor.
