VAT/GST transaction mapping: rates, place of supply, exemptions

Map transactions to VAT/GST treatments for {country_or_region}.

Inputs:
- Transaction list: {transactions}  # date, customer/vendor, country, item/service, amount, tax charged
- Product/service taxability notes: {taxability_notes}
- Customer types (B2B/B2C) and VAT IDs: {customer_info}
- Incoterms/shipping terms (if relevant): {shipping_terms}

Output:
1) Mapping table: transaction type, place of supply, VAT rate, exemption/reverse charge, evidence required.
2) Exceptions list: missing VAT IDs, wrong rate, incomplete evidence.
3) Recommended ERP tax codes and validation rules.
4) Compliance checklist for return preparation (output VAT, input VAT, adjustments).

Be explicit about assumptions; flag where local advice is needed.
