Terminology Glossary

Term	Category	Business Definition
Subcontracting Order (SCO)	Commitment Document	An authoritative authorization issued to a subcontractor specifying what finished goods to produce, which components to consume, expected yield, delivery terms, and tolling fees.
Packaging / Raw Materials	Component Asset	Company-owned physical inputs dispatched to a subcontractor, such as empty bottles, caps, labels, cartons, or active ingredients. These remain owned by the principal throughout the process.
Finished Goods (FG)	Output Asset	The completed product received back from the subcontractor, ready for inspection, quarantine release, and sale or internal use.
Bill of Materials (BOM)	Formulation Definition	A structured, versioned list of component quantities required to produce one unit of finished output, including scrap/yield assumptions and processing instructions.
Conversion Ratio / Yield Rate	Operational Term	The expected relationship between input components and finished output (e.g., 1,020 bottles + ingredients → 1,000 sellable units), used to plan and validate backflushing.
Subcontractor Virtual Location	Custody Concept	An on-book inventory location representing company-owned stock physically held at a third-party subcontractor’s premises. It is treated as an internal asset, not an external sale.
Component Transfer Note / Dispatch	Movement Document	The internal document recording the shipment of components from a company warehouse to a subcontractor virtual location. It transfers custody but not ownership.
Subcontracting Goods Received Note (GRN)	Receipt Document	The document recording the receipt of finished goods from the subcontractor, triggering quality inspection, quarantine, and backflushing.
Backflushing	Operational Term	The automated deduction of component quantities from the subcontractor virtual location based on finished-goods receipt and the approved BOM/yield assumptions.
Tolling / Service Fee	Financial Term	The amount payable to the subcontractor for processing, conversion, assembly, or packaging services, independent of the material value of the components consumed.
Setup Charge	Financial Term	A fixed fee invoiced per production run, batch, or campaign, often separate from the unit-based tolling fee.
Yield Loss	Operational Term	The acceptable difference between theoretical output and actual output due to process evaporation, breakage, or residue, captured within BOM tolerances.
Scrap	Operational Term	Material that is wasted, damaged, or otherwise unrecoverable during processing and must be reported for variance and accountability.
Quarantine Stock	Custody Concept	Finished goods or components physically received but held pending inspection, quality verification, or certificate review before becoming available for sale or use.
Subcontractor Return Note	Movement Document	A document recording the return of defective finished goods or unused components from the subcontractor virtual location back to the principal’s warehouse or to a disposal location.

Distinctions That Matter

Component Dispatch vs. Purchase

A Component Transfer Note is not a purchase. The company already owns the components; the movement merely changes their physical custody from an internal warehouse to a subcontractor virtual location. No expense, revenue, or accounts payable is recognized at dispatch.

Service PO vs. Subcontracting Order

The Procurement Service PO is the commercial commitment to pay the subcontractor for processing. The Subcontracting Order (SCO) is the operational authorization that governs what to produce, what to consume, and how much to expect. They are related through a polymorphic reference, but they belong to different bounded contexts.

Tolling Fee vs. Material Cost

The tolling fee is a service cost that must be capitalized into the value of the finished inventory. The material cost is the value of the components consumed. Together they form the total capitalized cost of the finished good:

$$ \text{Total Unit Cost} = \text{Raw Material Cost} + \text{Tolling Fee per Unit} $$
