Exclusive VPN corporation wants to automate their offering of complete B2B services and realizes that...

Large B2B order stability improves when Order Management uses Platform Events processing and when the commercial transaction is segmented into manageable site-based units before submission. Event-based orchestration avoids the tighter Batch Apex concurrency model, while site grouping or enterprise-sales capabilities reduce the number of lines and technical records processed in one transaction. Together they lower heap, CPU, and orchestration-plan pressure. This approach is preferable because it uses the platform feature designed for the exact lifecycle stage involved, rather than forcing the requirement into a neighboring layer. Simply requesting larger governor limits is not a sustainable design, and placing all lines into one oversized order preserves the underlying transaction-size problem. The workload should be scaled by both processing mode and transaction segmentation. In Communications Cloud, that separation materially affects maintainability, performance, and the accuracy of future MACD or order-processing behavior. The solution should therefore preserve parent-child and inventory dependencies, use standard qualification or orchestration semantics, and ensure that downstream systems receive only the information relevant to their responsibility. The same design also simplifies regression testing because the business rule is expressed in one authoritative place and can be validated independently from unrelated product or integration behavior.
