Exchange 1C documents with Diadoc without manual processing

Data exchange with Diadoc from 1C is built either on the operator's standard module or through integration via its API. The difference is not quality, but scope of applicability.

Kontur.Diadoc module for 1C An external processing tool or a configuration extension. Installed in local or server-based 1C, it supports standard configurations and covers the standard workflow: creating, sending, receiving, and signing documents directly in the accounting system interface. If you have a standard configuration and one operator, this is the shortest path, and you do not need to invent another integration instead.

Integration via API is needed where the module is not suitable or is not enough: cloud 1C, where an external processing tool cannot be installed; a custom configuration; custom approval routes; multiple operators at once and the need for a unified exchange log; high volume, where batch processing and automatic matching with contracts matter.

We implement both options and do not sell the second where the first is enough. How the module itself works, its versions, and platform requirements are covered in the article "Diadoc module for 1C".

The job does not end with the connection itself: the document must be posted correctly in accounting, otherwise finance will keep reconciling it manually.

Match incoming documents with counterparties, contracts, and orders according to your rules, not default ones. Structured formats such as UTD, invoices, acts, and delivery notes are checked for required fields. Signing with a machine-readable power of attorney. Statuses are returned to 1C: signed, rejected, canceled, so the document status is visible in the accounting system, not in the operator's portal. Roaming with counterparties from other operators. An exchange log with the history of each document, including where it stopped and why.

If counterparties use different operators, the same setup can be built for SBIS, Taxcom, and Astral: only the adapter changes, while the matching rules remain yours. Comparison of operators for 1C - in a separate breakdown.
