I focus on integrations that survive daily operations, not just demo environments. The most important part is stable product sync and clear ownership of truth for pricing, stock, and product attributes.

The second layer is process discipline: error handling, monitoring, and practical recovery routines. If one sync fails, the workflow should recover cleanly without creating duplicate or inconsistent records.

My rule is simple: choose predictable flows over clever flows. It keeps teams faster in the long run and protects operations when order volume grows.
