How modern retail chains unify brick-and-mortar boutique POS registers, warehouse dispatch hubs, and online e-commerce storefronts with millisecond atomic stock locks.
Available-to-promise inventory across outlets
Maintain sku_locations, stock_reservations, stock_movements and channel_versions. Available-to-promise equals on-hand minus active reservations and a configured safety buffer. Release reservations using an idempotent expiry job.
Workflow and data ownership
Storefront order → stock reservation → fulfilment → channel reconciliation
Confirm each system of record, the event owner and the recovery path before implementation. The sequence above is a proposed design for discussion, not measured production performance.

Failure cases and acceptance checks
Race online and till sales for the last unit. Replay returns and cancellations. Measure inventory divergence and stale-channel age instead of promising universal zero overselling.
Scope, measurement and handover
Agree the first release, test data, permissions and acceptance evidence in writing. Record the current operating baseline before setting targets. Hand over the accepted code, configuration and runbook under the project agreement; hosting, external APIs and maintenance remain separate budget items. Review the related service or guide.
