Billing and stock rules in Al Rayyan
Al Rayyan businesses do not charge VAT, because Qatar has not yet brought a VAT law into force. When it does, SalesMake can switch tax on for the products and outlets concerned, and earlier invoices stay as they were issued. An e-invoicing law has been approved without set dates, and invoices are already stored as structured records. Collections are recorded in Qatari riyals, and card payments made through the local NAPS network can be noted as receipts against the right invoice. Excise applies to some drinks in GCC states, so those packs can be flagged in the product list. Friday and Saturday form the weekend in Al Rayyan.
