Fast Inventory keeps the stock accurate; the rest of the Fast Suite moves it. Fast Production issues and consumes material through the same engine, Fast Purchase & Billing feed receipts and valuation, and Fast Planning reads the same reorder levels. Because they share one platform, the links are native — no export file, no middleware, no reconciliation.
Stock changes in two directions, and the Fast Suite drives both through Fast Inventory's movement engine. Production consumes material and returns finished goods; Purchase and Billing feed receipts and valuation and reduce stock on dispatch. Whichever product acts, the balance it changes is the same one the inventory ledger holds — no product-side copy to reconcile.
Because Fast Inventory, Production, Purchase, Billing and Planning share one platform, each product writes to the same tables the next reads. There is no import, no reconciliation and no drift between what one product shows and what another shows.
Every link below is a native table-level connection on the shared platform — the item master, the movement engine, the stock balance and its valuation are the same records read from every product, not files passed between separate systems.
When production runs in one system and inventory in another, the two never quite agree. On the shared platform they can't disagree: a Fast Production work order issues and consumes raw material through the same movement engine Fast Inventory uses, and finished goods are received back to stock. The moment the floor books consumption, the raw-material balance and its valuation move — visible in the inventory ledger without an import.
The rest of the suite works from the same balance. Fast Purchase & Billing feed goods receipts and rates into the item master, so a GRN brings stock on hand with its value and a dispatch reduces the same stock. Fast Planning reads the same reorder levels and live stock and nets against them. What one product commits, the next reads — one valuation, one balance, across the suite.
Fast Inventory answers "how much do I have, where, and what is it worth?" When the operation also needs to tell an operator exactly which pallet to put where and which lot to pick next on a scanner, Fast WMS is the superset that adds it — directed putaway and picking, pallet and bin capacity optimization, and handheld execution — on the very same item master and movement engine. You don't switch systems; you switch on more capability over the same stock.
Every Fast product reads the same item master — one code, UOM, tax group and reorder level, with no duplicate catalogue to keep in step.
A Fast Production work order issues and consumes material and returns finished goods through the same movement engine Fast Inventory uses.
Fast Purchase and Fast Billing feed goods receipts and rates into the item master, so stock and valuation come from the source document.
Fast Planning reads the same reorder levels and live stock and nets against them to raise work orders and purchase requisitions.
Whichever product moves stock, the posting lands in the same immutable stock ledger — one balance and one trail, valued consistently.
When you need directed putaway, picking, bin optimization and handheld work, Fast WMS adds them on the same engine — the same stock, more capability.
In a 30-minute demo we'll receive stock in Purchase, consume it on a Production work order and net it in Planning — all reading one item master and one ledger, no re-keying.
