Selling in Europe? VAT is handled.

Getting VAT wrong is a legal problem, not a bug. Most starters ignore it. This one ships with it switched on, and you can turn it off with one setting if you sell outside the EU.

VAT number validation through VIES
Reverse charge for B2B customers
PDF invoices with the right fields
English and Polish included, more through one translation file

Questions

Do I need to know JavaScript?

No. The frontend uses Jinja templates and HTMX, so everything is Python and HTML.

When does it ship?

About 4 weeks after pre-orders open. If it doesn't ship, you get a full refund.

How do I get the code?

After payment you get access to a private GitHub repository, including every future update.

Can I use it for client projects?

Yes, with the Unlimited plan.

I'm not in the EU. Is it still useful?

Yes. The VAT modules switch off with one setting, and everything else works the same.

Who made this?

A solo developer in Iceland who needed EU billing done right for his own products, then packaged it.
