Know-how for the small company.

ood.bg is an online program for invoices, stock and reports, built for Bulgarian small and medium companies. Issuing documents is free on every plan, and one account can hold an unlimited number of companies.

Sign up to ood.bg on the Start plan (€0), enter your company ID — the company details are filled in from the registry — and issue your first invoice in under a minute. No card, nothing to install.

In ood.bg, EUR is the default currency since 1 Jan 2026. Old documents stay in BGN, the rate is applied automatically and numbering continues without a break.

Ask D.O.B.I., the ood.bg AI assistant, “Who is late with payment?” — you get a list with amounts and days overdue and ready reminder drafts to send.

Yes. ood.bg allows an unlimited number of companies in one account, with separate data, rights and numbering for each and quick switching between them.

ood.bg handles sales, deliveries, transfers and stocktakes across several warehouses with FIFO, LIFO or average cost — stock updates with every invoice issued.

In ood.bg you send the document with a secure link, and the client signs on screen and confirms with a one-time e-mail code. When it was opened and signed is recorded in the audit log.
