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.

About

Facturwise is an invoicing platform for EU freelancers and small businesses with ZUGFeRD and Factur-X e-invoicing compliance built into every plan — including free. Germany mandates e-invoicing from 2027, France from September 2026. Most tools charge extra for compliance or don't support both standards. Facturwise generates fully compliant ZUGFeRD 2.4 and Factur-X 1.0.8 invoices automatically — no plugins, no configuration, no extra cost. Every invoice is a hybrid PDF/A-3 document with structured CII XML embedded inside — human-readable for your client, machine-readable for their accounting software. Beyond compliance: multilingual invoices in 6 languages, 30 currencies, SEPA QR codes for zero-fee bank transfers, automated recurring billing, payment reminders, expense tracking, client management, quotes, credit notes, and a financial dashboard. Start free, no credit card required.
