Sales orders
Stock is committed when you invoice.
In short
Tracked products reduce on-hand when you post an invoice (and increase when you post a bill). Estimates do not reserve stock. There is no live reservation or available-to-promise figure against a sales order in this login.

FAQ
Stock and invoices: common questions
Does accepting a quote reserve stock?
No.
Can I see committed vs available?
You see on-hand. There is no committed-by-SO figure.
Which plan includes this?
Inventory on Business and above.
Can I adjust stock without an invoice?
Yes — inventory adjustments in Catalog → Inventory.
On-hand is the truth
Reserve nothing until you raise the invoice.
That matches InventoryService: stock in from purchases, stock out from sales invoices.
