Scope of Supply — definition
Contractual description of the equipment, services, deliverables and responsibilities a supplier is obligated to provide under an agreement.
Scope of supply and CAPEX approval
Short answer: define the scope of supply before you ask for CAPEX approval. The approved budget is only as reliable as the scope behind it: anything outside the supplier's scope (civil works, utilities to battery limits, permits, freight and duties) must appear as a separate buyer cost line, and contingency should reflect how well that scope is defined.
Scope of supply typically clarifies boundaries such as mechanical, electrical and civil interfaces, installation responsibility, spare parts included, training, and documentation. Ambiguous scope boundaries are a common source of change orders and cost overruns.
Buyer checklist: scope of supply before CAPEX approval
Confirm each point before the budget goes for internal approval.
- Inclusions listed: design, manufacture, transport, installation or supervision, commissioning, training, documentation
- Exclusions listed and each one assigned to the buyer with its own budget line
- Interfaces defined: mechanical, electrical, control and civil battery limits
- Spare parts and consumables included in the price are stated
- Incoterm stated, with freight, insurance, duties and taxes budgeted
- Acceptance tests (FAT/SAT) and their criteria are part of the scope
- Contingency rate is shown separately and matches scope maturity
- Every quote being compared covers the same scope
Why it matters to industrial buyers
Clear scope boundaries prevent disputes about what is included in the contract price and who bears responsibility for interfacing works.
Key reference points
Common inclusions
Often covers design, manufacture, transport, installation supervision, commissioning support, training and documentation.
Common exclusions
Civil works, utilities up to battery limits, and local permits are frequently excluded and allocated to the buyer.
Commonly confused with
Technical specification
Scope of supply defines contractual responsibility and deliverables; the technical specification defines performance and design requirements.
How it is used in practice
The scope of supply for a packaging line specifies that the supplier delivers, installs and commissions the equipment, while the buyer provides utilities to the machine's connection points.
Frequently asked questions
What happens if scope of supply is not clearly defined?
Undefined boundaries commonly lead to change orders, schedule delays and cost disputes during execution.
Is scope of supply the same as a bill of quantities?
No, a bill of quantities itemises quantities and unit costs, while scope of supply describes contractual deliverables and responsibilities.
