    About this skill

    What it does

    The Nex Invoice Bot Pattern is a specialized tool for Belgian freelancers and agencies to automate their billing without the overhead of a traditional database. It generates a complete, JSON-backed invoicing system that handles client management, project tracking, and compliant PDF generation.

    Supported tools

    • Data Management: Flat-JSON storage for clients, projects, and invoices.
    • Compliance: Belgian-specific VAT logic and sequential invoice numbering.
    • PDF Generation: ReportLab integration for professional, ready-to-send invoices.
    • Front-end: Optional integration with Telegram for invoice creation on-the-go.

    Why use this skill

    Prompting an AI to "write an invoice" often results in illegal numbering or missing legal mentions. This skill enforces strict Belgian compliance rules: a global, gap-free numbering sequence (YYMMDD + 3-digit counter) and a toggle for "Kleine Onderneming" (0% VAT exemption) including the mandatory legal footer or standard 21% VAT calculations.

    What the output looks like

    You receive a modular Python codebase including a data store CRUD layer, a dedicated numbering engine, and a PDF generator. It ships with sample JSON schemas so you can start billing immediately by just filling in your IBAN and VAT number in the config file.
