I will connect KeyCRM to BAS Small Business with automatic order transfer. On the KeyCRM side, I will use a webhook for status change plus a polling reserve, on the BAS side, an HTTP service or COM automation for generating sales documents with the required details of the counterparty, nomenclature, and amounts. Question: Is BAS deployed locally or on a server with network access?

I have studied the technical specifications, the logic with the RTU and exchange is clear. To ensure everything works without failures, I will prepare an infrastructure diagram where I will show the application of important SaaS patterns:
Idempotence: to prevent duplicate orders or double payments in case of network failures.
Queues (Queue-Based): to ensure the system consistently processes any batches of orders without overloading the BAS.
Retry mechanisms: in case of temporary unavailability of the database.
Message me privately — I will send the diagrams and explain in detail what and why we will implement for maximum reliability.

✋ Hello! We are the IT company dZENcode.
We implement reliable integration between KeyCRM and BAS with two-way data synchronization (orders, clients, products, payments, and delivery statuses), supporting high loads, mechanisms for resending, and correct mapping of business logic (statuses, reserves, documents of the type RTU), relying on the team's experience, best practices, and our own developments.
Is BAS already published through HTTP services or does the API need to be set up from scratch?
Should the synchronization work completely in real-time through webhooks or is a queue/batch processing also needed for stability?

Good day!
We have experience in developing integrations between different systems, particularly between KeyCRM and BAS. We are implementing this project by creating a specialized service that will carry out automatic data transfer between these systems.
The service will perform the following functions:
- Tracking changes in orders in KeyCRM
- Automatic data transfer to BAS
- Generation of implementation documents and analytics
- Support for financial control
The execution of the project involves creating specialized code, integrating with existing systems, and conducting testing.
