FAQ

Frequently asked questions about business invoicing

Which tools help test a French B2B invoice?

Use VAT Calculator, French VAT Number Validator, SIRET/SIREN tools and fake RIB data.

What is the difference between SIREN, SIRET and VAT number?

SIREN identifies the company, SIRET identifies an establishment and the VAT number adds tax-specific structure.

Does the VAT calculator replace accounting software?

No. It is for quick checks and estimates, not official accounting.

How do I create realistic invoice test data?

Combine a fake company, SIRET, VAT number, net/gross amount and fake banking details.
