ToR (Terms of Reference)
Terms of Reference, abbreviated as ToR, is a procurement document that defines the scope, objectives, deliverables, timeline, and other conditions of a contract. ToRs are particularly common in consulting, advisory, and professional services procurements where the buyer needs to communicate complex requirements clearly. International development agencies such as the World Bank, the European Investment Bank, and United Nations bodies use ToRs as their primary procurement specification format.

Purpose of a Terms of Reference document
A ToR document serves three main purposes. First, it communicates to potential suppliers exactly what the buyer wants delivered. Second, it forms the technical basis of the eventual contract. Third, it provides the framework against which performance will be measured during contract delivery. A well-drafted ToR reduces ambiguity, sets clear expectations, and creates a shared understanding between buyer and supplier.
ToRs are most commonly used for service contracts, advisory engagements, technical assistance, research studies, and capacity building. Goods contracts and works contracts more commonly use technical specifications rather than ToRs, although the boundaries are fluid and many buyers blend both formats depending on the contract type.
Standard sections of a Terms of Reference
A complete ToR typically includes the following sections. The background section explains the context, the buyer's organisational situation, and the rationale for the contract. The objectives section sets out what the contract is intended to achieve, usually in terms of outcomes rather than activities. The scope of work section describes the activities the supplier will perform, the methodology expected, and any specific approaches required.
The deliverables section lists the specific outputs the supplier must produce, with format, content, and quality expectations. The timeline section establishes when deliverables are due, including any phasing of the work. The team requirements section describes the staff the supplier must provide, including roles, qualifications, and time commitments. The reporting and management section explains how the supplier will report progress and how the buyer will manage the contract.
Additional sections may cover risk management, ethical standards, data protection requirements, intellectual property arrangements, and dispute resolution. Comprehensive ToRs in major contracts can run to 50 pages or more, although many ToRs for smaller engagements fit comfortably in 10 to 15 pages.
Reading a ToR for bid preparation
When preparing a bid, suppliers should read the ToR multiple times with different lenses. The first read is for understanding the buyer's situation and the contract's purpose. The second read is for identifying mandatory requirements and constraints. The third read is for spotting opportunities to differentiate, including any flexibility in methodology, team composition, or deliverable format that allows the supplier to propose a stronger approach.
Pay close attention to the deliverables list and the team requirements. These two sections drive most of the bid effort. The deliverables determine the technical proposal, and the team requirements determine the financial proposal because team time is usually the largest cost component in service contracts. Mismatch between proposed deliverables and proposed team is one of the most common reasons bids lose.
Common ToR mistakes to avoid in supplier responses
- Proposing deliverables that go beyond what the ToR requires, which inflates the price without scoring any extra points.
- Underestimating the time required for each deliverable, which leads to delivery problems and reputation damage.
- Ignoring buyer-imposed methodology constraints in pursuit of a more elegant proposed approach, which can result in technical disqualification.
- Proposing junior staff for senior roles to reduce price, which fails the team qualification check.
- Not addressing ethical, data protection, or other compliance requirements in the proposal, which can result in non-compliant scoring.
