Clozo

Clozo is an EU-first billing tool for freelancers: send a professional proposal with a legally-binding e-signature, collect a deposit, and get paid in one link via Stripe (card / iDEAL / Bancontact) or SEPA. It validates your client's EU VAT number live against VIES, applies cross-border reverse-charge automatically, and turns every invoice into a compliant e-invoice in one click — ZUGFeRD, Factur-X, Peppol UBL, FacturaE, ebInterface and FatturaPA. It also handles recurring/retainer billing, time tracking that exports into an invoice, expense tracking with DATEV (GoBD) export, and full GDPR data export. Available in English, German, Dutch, French, Spanish and Polish.
