    About this skill

    The problem

    Month-end reconciliation for small product businesses is often slow and error-prone. Developers and solo founders struggle to separate operating cash from tax set-asides without getting bogged down in complex ERP software.

    What it does

    • Generates a standardized docs/close.md checklist for one calendar month.
    • Calculates net sales, opex, and expected cash ending versus actual cash.
    • Computes tax set-aside memo balances based on buyer-defined rates and bases.
    • Identifies financial exceptions like non-zero deltas, missing exports, and out-of-month sales.
    • Strips sensitive house bank account numbers and processor IDs from generated reports.

    Why this beats prompting it yourself

    This skill enforces strict arithmetic rigor and prevents "delta plugging" where unexplained cash differences are hidden in opex. It maintains a hard boundary against providing unauthorized tax or legal advice, ensuring reports remain objective financial snapshots rather than risky recommendations.

    Use cases

    • Closing a month for a SaaS product using Stripe and hosting exports.
    • Calculating a tax set-aside memo for a solo developer business.
    • Identifying cash discrepancies between bank statements and sales reports.
    • Standardizing month-end documentation across multiple small software products.

    Known limitations

    Does not support multi-entity accounting, payroll, or inventory management. Requires buyer-supplied tax rates and cash totals as it cannot log into banks or tax portals.
