Procurement for Manufacturing
How Odoo purchase and replenishment rules supply manufacturing: reordering rules, MTO buy, vendor lead times, and MO-driven component demand.

Procurement for manufacturing covers how bought components reach the stock locations MOs reserve from — via reordering rules, make-to-order purchase triggers, or manual POs tied to planner review.
Vendor lead times, minimum order quantities, and purchase UoM must align with BoM UoM or MOs confirm with theoretical stock that never arrives in usable units.
Subcontract service POs are a special case: components resupply separately from the processing fee. Purchase and manufacturing must coordinate both legs.
MOs fail for missing parts even when purchase insists they ordered everything — often because POs hit the wrong location, wrong UoM, or arrived after the MO confirmation window.
This article ties purchase behavior to manufacturing demand generation.
Component need originates from confirmed MOs (BoM explosion), reordering rules on components, or MTO purchase routes on sales-driven demand. Each path creates purchase proposals or RFQs according to product configuration.
Planners need one view of what MOs in the next two weeks require versus what POs already cover — native procurement reports or custom dashboards fill this gap.
- ▸MO component requirements
- ▸Orderpoints (min/max) on components
- ▸MTO Buy on SO-driven need
- ▸Manual PO for spot buys and substitutes
Orderpoints suit MTS component buffers — raw materials you want on shelf before MOs drop. Set min/max per warehouse and review after seasonal demand shifts.
Overstocking every component ties cash; understocking stops the line. Tune rules using shortage history from the first live production month.
Vendor pricelines, lead times, and vendor delay statistics feed planned PO dates. Blanket agreements and call-off POs help high-volume parts without duplicate manual entry.
Alternate vendors need explicit planner rules — Odoo does not always auto-switch on shortage without configuration or Customization.
Receipts must post to locations MOs reserve from. Quality holds on incoming inspection delay availability even when PO shows received.

- ✓Align purchase UoM and BoM UoM with conversion factors tested on top ten components.
- ✓Review orderpoints monthly during the first production quarter.
- ✓Tie PO expected dates to MO planned start for critical path parts.
- ✓Separate subcontract service PO training from component PO training.
- ✓Use vendor lead time buffers for imported long-lead items on MTO orders.
- ✓Expose component shortage list to buyers daily during peak season.
- !Buy route on finished goods when only components should be purchased.
- !Receipt to transit location not linked to manufacturing stock.
- !MO confirmed before PO placed for long-lead exclusive components.
- !Vendor MOQ forcing overbuy without planner adjustment of orderpoints.
- !Ignoring partial receipts on multi-line POs tied to one MO.
- !Duplicate POs from both orderpoint and MO procurement without merging.
Procurement keeps MOs fed — lead times, locations, and UoM are as important as vendor price.
Next, reconcile open MO component shortages against open PO lines for your top product family.

Frequently asked questions
Does Odoo auto-create POs from MOs?
When components use buy routes or MTO procurement, confirmation can generate RFQs or POs according to rules. Planners often review proposals before send depending on configuration.
How do I buy for a specific MO only?
Use MO-linked procurement or manual PO with destination link to the MO need. Avoid blanket overstock if the part is single-use for one job.
What about consignment vendor stock?
Model with dedicated locations and ownership rules. Manufacturing reservation must pull from consignment location when that is the commercial arrangement.
Can purchase see future MO component demand?
Manufacturing reports and procurement schedules show planned needs. Custom reports help when standard views lack horizon filters buyers need.
