The framework is law, the rollout dates are not published yet, and that gap is the most useful moment to understand it. Here is what changes about issuing an invoice, and what it means for a shop that sometimes loses its connection.
When stock goes missing, the instinct is to suspect people. Sometimes that is right. But the standard definition of shrinkage contains three causes, and only one of them is theft.
The full stock count is a ritual: shop closed, everyone in on a Sunday, a number at the end that nobody quite believes. There is a better way to spend the same hours, and there is published support for it.
Every argument for taking stock control seriously rests on one premise: that the number in your system is usually not the number on your shelf. That premise has been measured, by academics, at a retailer that already had a real system.
