What problem does it solve? Issuing legally valid invoices in Israel requires choosing the correct document type, calculating 18% VAT correctly, validating 9-digit TINs, and obtaining SHAAM allocation numbers above progressive thresholds—mistakes make invoices invalid for tax deduction. ## Core Features & Use Cases - Invoice Type Selection: Guides users through Israeli document types 300 (tax invoice), 305 (tax invoice/receipt), 310 (credit invoice), 320 (receipt), and 330 (proforma) with required fields per type. - Compliance Validation: The bundled Python script checks TIN check digits, VAT calculations, invoice dates, and allocation number requirements against date-based thresholds (25,000 NIS down to 5,000 NIS from June 2026). - SHAAM API Guidance: Reference documentation covers allocation number requests, authentication, and error codes for the Israel Tax Authority API. - Use Case: A user asks to create a 15,000 NIS B2B tax invoice; the Skill calculates VAT (2,700 NIS), determines an allocation number is required, and produces a compliant invoice document. ## Quick Start Ask the assistant to create an Israeli tax invoice for a specific amount and client, providing seller and buyer business details.
