Name the source of truth
A useful inventory connection starts by naming the system that owns each fact. Product identity, on-hand quantity, online availability, reserved stock, and fulfillment status may not all come from the same place.
Design for timing and exceptions
Even connected systems update on a schedule or through events. Decide what the storefront should do when a source is delayed, an item is reserved at the counter, or an online order arrives during a busy period.
- Document sync frequency and ownership
- Keep missing data distinct from a true zero
- Test refunds, cancellations, and partial fulfillment
- Give staff a visible exception queue
Measure accuracy before expanding
Start with a defined set of products and compare what the storefront shows with what staff can actually fulfill. Expand when discrepancies have an owner and a repeatable resolution path.
