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 client EU VAT live (VIES), applies cross-border reverse-charge automatically, and generates compliant e-invoices in one click — ZUGFeRD, Factur-X, Peppol UBL, FacturaE, ebInterface, FatturaPA. Plus recurring billing, time tracking, expenses with DATEV export, and GDPR data export. Built for EU freelancers and micro-studios who want proposals, signatures, invoices, payments and expenses in one place instead of four separate tools.
