What problem does it solve? Month-end closing often hides mismatches between accounting records and actual payment settlements, leaving uncategorized expenses, duplicate entries, and missing source documents that surface only months later. This Skill reconciles your books against acquiring and bank data, flags every discrepancy, and produces a ready-to-archive closing package. ## Core Features & Use Cases - Three-way reconciliation: Matches accounting entries (1C/MoySklad) against payment sources (YuKassa, Tinkoff, SBP, bank statements) by amount and date, classifying unmatched settlements, unmatched bookings, and amount mismatches. - Anomaly flagging: Detects transactions without a category, suspected duplicates, and entries over 5,000 RUB missing primary documents, recommending an action for each without auto-fixing anything. - P&L summary and closing package: Generates a plain-language profit-and-loss summary plus an XLSX workbook (reconciliation, flagged items, P&L, trial balance) and a one-page PDF summary. - Use Case: Tell the assistant to close March; it finds 3 YuKassa settlements missing from the books, 11 uncategorized transactions, and one duplicate supplier payment, then exports close-packet-2026-03.xlsx and close-packet-2026-03.pdf after your review. ## Quick Start Ask the assistant to close last month and reconcile my accounting with payment settlements, then export the closing package.
