Description

Coretool is an online invoicing platform designed specifically for freelancers, sole traders, tradespeople, small service businesses, and other enterprises in Germany. With this application, users can generate and oversee quotes and invoices, including compliance with XRechnung and ZUGFeRD e-invoicing standards, manage customer relationships, issue payment reminders, and schedule appointments. The software integrates GiroCode QR codes, facilitates digital signatures for quotes, and enables e-invoice document validation through its REST API. By utilizing API-based workflows, users can link Coretool with automation platforms like Make, Zapier, and n8n, though access to certain specialized modules may require approval. Additionally, it allows users to incorporate calendar feeds into Google, Apple, or Outlook calendars. An optional Kalkulations-Assistent feature aids in estimating projects, calculating materials and labor, and producing quotes. Coretool operates entirely within a web browser, eliminating the need for any local software installation. The free plan permits the issuance of three invoices each month, while the Solo plan is available for €9 per month plus VAT and offers the flexibility of monthly cancellation. Furthermore, the intuitive interface makes it easy for users to navigate through the various functionalities and enhance their invoicing experience.

Description

InvoiceXML serves as an API-centric platform tailored for achieving e-invoice compliance across Europe. Its REST API is capable of generating, validating, and converting a wide array of formats that fall under EN 16931, including Factur-X, ZUGFeRD, XRechnung, UBL, and CII. The generation process takes in clean JSON data and produces either a compliant XML document or a PDF/A-3 hybrid invoice, complete with embedded XML following specific formatting guidelines. Validation is conducted using the official Schematron rulesets, which not only deliver structured results but also provide accessible explanations in plain language alongside the raw outputs of the rules. For format conversion, the API endpoint (POST /v1/convert/{from}/to/{format}) allows the transformation of any supported format into another via a unified internal representation. Additionally, a dedicated namespace, /v1/transform/, facilitates AI-driven extraction from older PDF invoices into organized XML. Moreover, No-Code integrations enable users without programming skills to access core functionalities seamlessly. The MCP server supplies a robust compliance toolkit designed for AI-assisted workflows, ensuring that the platform is consistently aligned with the latest standards, requiring no ongoing maintenance for users. This approach not only simplifies the compliance process but also enhances efficiency for businesses navigating the e-invoicing landscape.
