DocsInBox is an electronic waybill exchange system. The supplier, using special 1C processing, sends invoices. And in a couple of minutes they are in iiko. The automated invoice entry system minimizes the chance of errors. The latest versions of DocsInbox added support for EGAIS. Now the acceptance of goods is done using a mobile phone directly upon receipt. Integration with iiko occurs by installing the Docsinbox plugin, which adds a button to the main iikoOffice menu.
