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

rechnungswandler.de is a browser-based e-invoicing tool for freelancers and small businesses, particularly in Germany. It converts invoice data entered in a form or extracted from PDF, Word, Excel and scanned PDF files into XRechnung or ZUGFeRD documents aligned with EN 16931. Users can review extracted fields and download the completed invoice; a viewer also opens and checks received e-invoices. Conversion and viewing run locally in the browser, so invoice files are not uploaded for these operations. Pro features include retaining the original document layout, batch conversion, saved customer details, reusable templates, payment reminders and validation reports. Optional AI assistance can suggest missing fields. Users can create invoices in the web form or adapt existing invoice files without installing desktop software. A free tier with usage limits and paid 24-hour, monthly and annual plans are available.
