About

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.

About

Coretool is a browser-based invoicing application for German businesses, freelancers, sole traders, tradespeople, and small service businesses. Users can create and manage quotes and invoices, including XRechnung and ZUGFeRD e-invoices, track customers, send payment reminders, and organize appointments. The app supports GiroCode QR codes, digital quote signatures, and validation of e-invoice documents through its REST API. API-based workflows can connect with automation tools such as Make, Zapier, and n8n; availability of some platform-specific modules may depend on approval. Calendar feeds can be added to Google, Apple, or Outlook calendars. The optional Kalkulations-Assistent supports project estimates, material and labor calculations, and quote creation. Coretool runs in a web browser without local installation. Its free plan allows three invoices per month; Solo costs €9/month plus VAT and can be canceled monthly.
