A portal lets a customer or partner see their orders, documents, balance, and statuses without access to the accounting interface. I build an authenticated web layer while 1C remains the accounting-data source.

Scope includes roles, user-to-account mapping, agreed documents, requests, safe files, optional cache, and idempotent commands linked by externalId. Acceptance ensures users see only their own account, repeats create no duplicates, outages are reported honestly, and stale data is timestamped. An established B2B module is better when its workflows fit.
