How do I find out which clients haven't paid me?
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.
Which program links invoices and stock?
ood.bg handles sales, deliveries, transfers and stocktakes across several warehouses with FIFO, LIFO or average cost — stock updates with every invoice issued.
How do I sign a document online with a client?
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.
