    About this skill

    What it does

    This skill acts as an automated audit assistant for VAT filing periods (specialized for Belgian VAT logic). It analyzes financial exports—such as sales journals, purchase journals, and general ledgers—to identify discrepancies, tariff errors, and missing data before the final tax return is submitted.

    Why use this skill

    Manual VAT reconciliation is time-consuming and prone to human error. This skill performs a mechanical plausibility check at scale, catching issues that humans might miss. It is more effective than standard prompting because it follows a structured multi-step audit protocol, ensuring no checks (like invoice sequencing or reverse-charge consistency) are skipped silently. It bridges the gap between raw accounting data and a final, clean tax return.

    Supported Tools & Formats

    • CSV/Excel exports from accounting software (Exact Online, Yuki, Octopus, Silverfin, etc.)
    • Sales and Purchase Journals
    • VAT trial balances and Ledgers

    Output format

    The skill generates a structured Markdown report featuring a checklist with status indicators (✅, ⚠, or NOT CONTROLLABLE). It provides a detailed list of exceptions at the transaction level and a prepared questionnaire for the end-client to resolve missing information.
