Inventory usage in Field

Technicians can record parts used on a visit when plan feature inventory is on and the job/type allows it. Office stock lives under Inventory → Stock.

Field Stock used writes an ACTUAL line (often billable) and a Consumption movement in one transaction. That is not an invoice by itself.

Workflow

1. Office keeps catalog items (Product + Track inventory for this product) and stock at locations (warehouse, van).
2. Technician default default_stock_location_id (if set) is a van/warehouse pointer — not GPS.
3. On the Field job, record Stock used against the visit.
4. Movements appear in Movements. Parts requests are a separate request workflow, not silent consumption.

Interactive consume with require_sufficient refuses when on-hand is too low. Field offline replay can still post a consumption that goes negative.

What does not consume

Appointment Closeout, office work-order Complete, issuing an invoice, approving a parts request, or creating a PO. Closeout without Stock used does not change on-hand.

Limits

• This is not available-to-promise promising. There is no reserved quantity.
• Customer equipment is Assets, not inventory.
• Usage on the visit is not an invoice by itself. Office still issues invoices if you bill parts (Actual lines).
• Killing the browser tab does not guarantee outbox delivery.

If Stock used is missing: inventory entitlement off; item is a Service; tracking unchecked; no default location and no location picked.
