E-invoicing for trades and repair businesses: what to do now

A PDF by email — for years that was the “electronic invoice.” Those days are over: a real e-invoice is a structured, machine-readable format that accounting systems read in automatically. And in B2B business it’s becoming mandatory step by step.

What is an e-invoice — and what isn’t?

An e-invoice is a structured data set following the European standard, not an image and not a simple PDF. The recipient’s system reads line items, amounts, and tax rates directly — without retyping, without text recognition.

Not e-invoices in the sense of the obligation are: paper invoices, scanned invoices, and plain PDFs.

Who does the obligation affect?

In Germany, since the start of 2025: companies must be able to receive e-invoices; the obligation to issue them in B2B business follows in stages over the coming years. In Austria, e-invoices to the federal government have long been mandatory — and in the B2B sphere the trend is moving in the same direction.

Relevant for repair businesses: as soon as you have business customers — company fleets, dealers, property managers — sooner or later you’ll be asked for an e-invoice. Whoever only starts looking for a solution then is looking under time pressure.

What small businesses should concretely do now

1. Review how you issue invoices. Are your invoices created in Word or Excel? Then there’s no way around a system that can output structured formats — you can’t build an e-invoice by hand.

2. Pay attention to clean fundamentals. E-invoicing requires what already applies anyway: sequential invoice numbers, correct tax rates, GoBD-compliant locking of records. A system that makes documents unchangeable once locked meets this automatically.

3. Connect your tax advisor. Handing over a collected export instead of individual emails saves time on both sides — and your tax advisor will thank you for it.

The real point: no separate process

The e-invoice shouldn’t be a second invoicing path alongside the normal one. Ideally it comes out of the same click as any other invoice: job completed, invoice generated — whether as a PDF for the private customer or structured for the business customer is decided by the recipient, not by your workload.

That’s exactly how it’s solved in SimpliServ: same invoice, same workflow, structured format in the background — including number ranges, record locking, and a batch export for bookkeeping.

Conclusion

The e-invoice is less a technical topic than an occasion to tidy up your own invoicing. Whoever switches today from Word to a system that thinks about jobs, invoices, and structured formats together has the obligation handled before it takes effect.
