A 1C–CRM integration connects sales and accounting: the CRM manages leads and communication, while 1C manages contracts, invoices, and fulfilment. The two systems should not compete for the same customer record.
Scope covers entity mapping, duplicate keys, status ownership, CRM webhooks, 1C APIs, transformation, queues, and sync logs. Full sales-pipeline configuration or CRM migration is separate. Acceptance ensures one account per repeated deal event, permitted status flow, visible conflicts, and externalId on both sides.
