Three CRM ↔ F&O integration patterns that actually hold up

Dataverse Dual-Write is the default answer for synchronising accounts, products, and orders between Dynamics 365 Customer Engagement and Finance & Operations — and for a large share of programmes, it's the right one.

But three recurring scenarios push teams past it: high-volume transactional sync where near-real-time matters more than dual-write's table coverage, custom entities that Dual-Write doesn't map out of the box, and multi-F&O-instance topologies where a single CE environment needs to reconcile against more than one operations backend.

In those cases we reach for Azure Service Bus with Dataverse event publishing on one side and F&O's business events on the other, with a reconciliation job as a safety net — not a replacement for the event-driven path, but a way to catch what the events miss.
