Drop Cover. a replenishment principle stating that a delivery rhythm is proven by what actually arrived, never by what the system is configured to expect. Supplier cadence is derived from the store’s own receiving history, and each order covers the true gap to the next drop, as the receipts prove it, not as the schedule promises it.
The idea
Every ordering system holds a belief about how often the truck comes. Weekly, twice a week, fortnightly. That belief is configuration, typed in once and trusted forever. The receiving history tells the truth, and the truth churns: routes change, reps change, a fortnightly line quietly becomes monthly. A store bank we studied showed hundreds of sustained delivery-day switches in under two years. Order to the configured rhythm and every switch silently starves or floods the shelf.
The law in practice
Cadence is read from receipts, per supplier per store, and re-read continuously so a regime change resets the read. The order then buys the gap the evidence supports. When the gap to the next drop is long, depth goes up. When the truck comes twice a week, depth comes down and the capital goes to work somewhere else, per Capital Velocity.
The month-end connection
Drop cover is how Community Rhythm lands in practice. The busy window is built on the last deliveries before it. Delivery days anchor the timing, so the stock lands as the money arrives, not after it has been spent somewhere else.
What it replaces
Configured lead times nobody re-checks, fixed order days that ignore what arrives and the quiet stockouts caused by a schedule the supplier abandoned months ago.
