    • Compiled the nex-invoice-bot-pattern

    I've generated your invoicing system

    • config.py: Set to Kleine Onderneming (0% VAT).
    • numbering.py: Implements YYMMDDXXX sequential logic.
    • pdf_generator.py: Includes mandatory Belgian exemption footer.
    • data_store.py: JSON-based CRUD for your records.

    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.

    • Not a full accounting tool: lacks VAT return filing.
    • JSON storage: not for high-volume enterprise data.
    • Specific to Belgian VAT: requires manual adjustment for other countries.

    Frequently Asked Questions

    This skill provides a structured Python-based framework that enforces Belgian tax regulations, such as sequential numbering and specific VAT exemption footers, which standard AI prompts often ignore or hallucinate.

    Yes, the bot includes a 'Kleine Onderneming' toggle that automatically applies the 0% VAT exemption and injects the mandatory legal citation required by Belgian law into your PDFs.

    The skill is a modular Python codebase designed to bridge with any LLM that supports function calling or code execution, providing the stable logic layer for an AI agent to handle your billing.

    Upon purchase, you receive the full Python source code for the numbering engine, PDF generator, and data management layer, along with sample JSON schemas and a configuration template.

    No database is required; the system uses flat JSON files for easy version control and portability, making it lightweight enough to run on local environments or small cloud instances.

    The code allows you to easily input your company details, IBAN, and branding in a central configuration file, which the PDF engine then uses to brand all generated invoices.
