Accounting Software That Stays Yours, Wherever You Do Business
WDI Billing is invoicing and accounting software built country by country, not retrofitted from a single market. Every country edition below follows that country's own VAT rules, e-invoicing mandates, and reporting formats -- and your data stays under your control, not locked into someone else's export format.
About WDI Billing
EDIT ME: two or three sentences here on the company itself -- who built it, why, and how long you've been running. This section currently has no real copy.
The principle is the same in every market we support: your books are yours. No forced cloud lock-in, no proprietary export formats, and compliance handled for the country you actually operate in.
