What does the Replenishment module decide?

For every product at every store, it recalculates the optimal stock level each day (the Dynamic Buffer) and turns the gap between that target and what the store holds into a store order from the central warehouse, within your local and global constraints. Assortment, new products, new stores, time events and promotions, merchandising pushes, and online/wholesale allocation all adjust that same daily calculation.

Do I need the Forecasting module to use Replenishment?

No. Replenishment, Forecasting, and Buy Plan are licensed independently. Replenishment covers stock movement from the central warehouse to stores and channels; Forecasting covers what the central warehouse should purchase from suppliers.

How long does a Replenishment rollout take?

At Bath & Body Works (Delta Israel Brands), the initial deployment took two months and went live in two markets, Israel and Germany, with about 70% of the replenishment process automated. Every rollout starts by scoping your data feed: one row per SKU per day with date, sku, and units sold is the minimum. See the Integrations page for detail.

How is Replenishment priced?

Per store per month, in declining brackets with a 5-store minimum: $175 per store for stores 1–10, $125 for stores 11–30, $75 for stores 31–60, and $25 for every store beyond 60. The pricing page has an instant calculator.

Replenishment module

AI-Powered Retail Replenishment

Built forReplenishment, allocation and merchandising teams that ship from a central warehouse to a chain of stores, and the store managers who'd rather not build orders by hand.

Capabilities

Nine capabilities, one daily store order

Every capability feeds the same decision: the right quantity of each product for each store. Launches, store openings, holidays, promotions and online demand adjust it instead of being planned in separate spreadsheets.
