Stock Reservations
Understanding how orders reserve inventory
Stock Reservations
Reservations hold inventory for a sales order so it can't be used by other orders or transfers.
How Reservations Work
Manual Reservation
Reserving stock is an explicit action — stock is not reserved automatically when an order is approved. To reserve:
- Open the sales order (the order must be Open)
- In the products table, choose Reserve on a product
- Select the warehouse(s) and the quantity to reserve per warehouse
- Confirm
The system validates each reservation:
- You can only reserve for orders in the Open status
- You cannot reserve more than the product's pending quantity on the order
- Each warehouse must have enough available stock
Stock Quantities
| Quantity | Definition |
|---|---|
| On Hand | Physical stock present |
| Reserved | Held for orders and stock transfers |
| In Transit | Stock currently being moved |
| Available | On Hand - Reserved - In Transit |
Reservation Status
Order Line Quantities
Each order line tracks fulfillment quantities:
| Quantity | Meaning |
|---|---|
| Reserved | Quantity currently reserved |
| Picked | Quantity picked from stock |
| Shipped | Quantity shipped |
| Delivered | Quantity delivered |
| Returned | Quantity returned |
| Cancelled | Quantity cancelled |
| Pending | Quantity still to be reserved/fulfilled |
A product can be partially reserved — for example 75 of 100 units reserved, with 25 still pending until more stock is available.
Managing Reservations
Viewing Reservations
Reservations are shown on the sales order, grouped by warehouse (stock site).
Releasing Reservations
To free reserved stock:
- Cancel (part of) a reservation directly on the order
- Cancelling the order or cancelling products releases their reservations
Reservations that are already assigned to a picklist cannot be cancelled directly — cancel the picklist first.
From Reservation to Picklist
Reserved stock is fulfilled through picklists. From the order you create a picklist out of reserved stock in three steps:
- Select the warehouse
- Select the reserved stock to pick
- Confirm the picklist
See Fulfillment for the rest of the process.
Best Practices
Reserve Early
- Reserve stock as soon as an order is approved
- Reserved stock cannot be taken by other orders or transfers
Keep Reservations Accurate
- Release reservations for quantities you no longer expect to ship
- Cancel picklists separately when reserved stock is already assigned to one
