How is master product data shared while stock is tracked per branch?

Product *details* are stored once as master data — name, description, type, attributes, images — and every branch shares that single catalogue, so product information is never re-entered per location. What differs per branch is stock: each branch maintains its own on-hand quantity (and optionally its own price override) for a product via per-branch stock records. So all branches sell "the…

Product *details* are stored once as master data — name, description, type, attributes, images — and every branch shares that single catalogue, so product information is never re-entered per location. What differs per branch is stock: each branch maintains its own on-hand quantity (and optionally its own price override) for a product via per-branch stock records.
