What Wave says about users outside the US and Canada
Wave’s help article on users outside the United States and Canada says that, following its November 2020 decision to focus on those two countries, product and customer support for other users was discontinued. It says these users can no longer send invoices or reminders through Wave, that accounts remain active but this may change, and that compliance could not be guaranteed outside supported regions. Wave suggests these users move to its partner, Zoho Books.
Wave’s home page describes accounting, invoicing, payments, payroll and receipts for small business owners. It does not mention VAT. For a UAE business that is registered for VAT, that is the gap: no 5% treatment per line designed for the FTA, and no VAT 201 preparation.
