Software developer
Software developer invoice template 2026 — Free, EU VAT-ready
Software developers ship in different time-frames: hourly bug hunts, fixed-scope features, monthly retainers, on-call. The smart VAT engine especially shines for digital services across the EU, where B2C sales above €10 000/year trigger destination-country VAT via OSS — get it wrong and the back-tax hurts.
Smart VAT engine
Cross-border B2C supply within the EU. As you are not registered for OSS, your home-country VAT (20% in AT) applies. Once your annual EU-wide distance sales exceed €10 000, OSS registration becomes mandatory.
- ⚠ If your annual cross-border B2C sales in the EU exceed €10 000, you must register for OSS and switch to destination-country VAT.
- ⚠ The customer is marked as a business but has no VAT number. Treated as B2C unless a valid VAT number is provided.

Frequently asked questions
Short answers to the questions people most often ask before relying on the page.
- How does VAT work for SaaS sold to EU consumers?
- Once you cross €10 000/year in cross-border B2C digital services, you must register for the One-Stop-Shop (OSS) and apply the destination-country VAT rate to each consumer sale. This template's Smart VAT engine flips to OSS automatically when you toggle the OSS-registered checkbox and select a non-domestic B2C customer.
