Contract management after signature: obligations, changes, price reviews and renewals
A sourcing project ends with a signature, and that is usually where attention moves elsewhere. Yet the savings, service levels and protections negotiated during the tender only exist if someone makes them happen over the life of the contract. Contract management is that work: knowing what each party promised, checking that it is delivered, handling change in a controlled way, and deciding in good time what happens when the contract ends.
Contract management is not contract administration
The two are often confused. Contract administration covers the paperwork: storing the signed document, recording key dates, raising purchase orders against it and processing invoices. Contract management is broader. It covers the relationship and the outcomes: whether the supplier performs, whether the contract still fits the need, whether risks are under control and whether the expected value is reached. A contract can be perfectly administered and still badly managed, with every renewal date recorded and nobody checking that the service is any good.
In the procurement cycle, contract management is the long final step that runs from award to exit. For a multi-year service contract it can last far longer than the sourcing that preceded it.
1. Plan the handover before award
The people who negotiated the contract are rarely the people who will live with it. Before signature, plan a handover meeting between the sourcing team, the future contract manager and the budget holder, and then a kick-off meeting with the supplier. The handover should cover:
- what was bought and why, including the requirements that were traded away during negotiation;
- the commercial model: prices, indexation, volume commitments, discounts and payment terms;
- the points the supplier pushed back on hardest, which are the clauses most likely to be tested later;
- the risks identified during sourcing and the mitigations agreed;
- who on each side has authority to approve changes, accept deliverables and sign off invoices.
2. Turn the contract into an obligations register
A signed contract is written to be legally complete, not to be used day to day. The most practical tool in contract management is a register that extracts every obligation, deadline and right into a list someone can work from. A simple spreadsheet is enough for most contracts; contract lifecycle management software helps when there are many.
| Type | Examples | Owner |
|---|---|---|
| Supplier obligations | Service levels, delivery dates, reports, insurance certificates, audits | Contract manager checks; supplier delivers |
| Buyer obligations | Forecasts, access to sites or systems, approvals, timely payment | Budget holder or user department |
| Dates | Price review windows, notice periods, renewal and expiry, warranty end | Contract manager, with calendar alerts |
| Rights and remedies | Service credits, step-in, audit rights, termination for convenience | Contract manager and legal |
The buyer's own obligations are easy to forget and often explain poor supplier performance: late forecasts, slow approvals and late payment all affect what a supplier can deliver. Payment obligations deserve particular care because statutory limits and late payment interest apply in many countries; check the statutory payment terms and late payment rules that apply to the contract.
3. Assign roles and tier the contracts
Not every contract needs the same effort. Most organisations tier contracts by value, risk and complexity. A low-risk catalogue agreement may need little more than an annual check and a renewal reminder. A critical outsourced service may need a named contract manager, monthly operational meetings, quarterly business reviews and an annual strategic review with senior people on both sides.
Whatever the tier, write down who does what. A common split is: the contract manager owns the relationship and the register; the user department confirms delivery and quality; finance pays against the agreed terms; legal is consulted on disputes, changes to terms and termination. Name a counterpart at the supplier for each of these.
4. Review performance against what was agreed
Performance management works when it measures what the contract actually requires, with definitions both sides accept. Use the KPIs and service levels written into the contract, collect the data on a fixed schedule and review trends rather than single incidents. Our guide to supplier evaluation scorecards covers how to choose, define and weight indicators.
Where the contract provides remedies such as service credits, apply them consistently. Waiving them every time weakens the contract and can, depending on the law that applies and the wording, make them harder to enforce later. If a remedy no longer makes sense, change the contract formally rather than ignoring it.
5. Control change
Almost every contract changes during its life: volumes move, specifications evolve, new sites are added, legislation changes. Uncontrolled change is where value leaks away, through extra work ordered informally and invoiced later at prices nobody negotiated. A simple change control procedure prevents most of this:
- Any change request is made in writing and describes the change, the reason and its urgency.
- The supplier states the impact on price, timing, service levels and risk.
- Someone with delegated authority approves or rejects it, within limits set in advance.
- Approved changes are recorded as a formal variation, and the register and purchase orders are updated.
Check the contract's own variation clause first: many require changes to be in writing and signed by authorised representatives.
Changes to public contracts
In the public sector, changing a contract after award is regulated, because a large enough change can amount to a new contract that should have been competed. In the EU, Article 72 of Directive 2014/24/EU lists the cases in which a contract may be modified without a new procurement procedure, including clear review clauses written into the original documents and small changes below set value limits; substantial modifications require a new procedure. In the UK, the Procurement Act 2023 sets out permitted modifications and requires a contract change notice to be published before many modifications. The Act also requires contracting authorities, before entering into a public contract worth more than £5 million, to set at least three key performance indicators, subject to exceptions, and to publish them (see section 52, and our guide to the UK Procurement Act 2023). Public buyers should take legal advice before agreeing significant variations.
6. Manage prices over time
Long contracts usually include a mechanism to adjust prices: indexation to a published index, a fixed annual review, or a reopener if a cost driver moves beyond a band. Each needs active handling. Put the review windows in the calendar, check which index the contract names and how the formula works, and verify the supplier's calculation rather than accepting it. If the contract has no adjustment mechanism, a supplier's request for an increase is a negotiation, not an entitlement; weigh it against the risk of the supplier exiting or cutting quality.
Price is only part of the cost. Track the spend actually incurred against the contract, including variations and extras, and compare it with the business case that justified the award. The total cost of ownership method is as useful after award as before it.
7. Handle issues before they become disputes
Most contracts set out an escalation path: operational managers first, then senior managers, then mediation or another dispute resolution step before court or arbitration. Use it early. Record issues in writing with dates and evidence, keep minutes of review meetings and agree actions with owners. A clear record is what protects both parties if a disagreement does escalate, and it often prevents escalation in the first place.
8. Decide on renewal and exit in good time
The end of a contract is a decision, not an event. Well before the notice period for renewal or termination opens, review whether the need has changed, how the supplier has performed, what the market now offers and what it would cost to switch. Then choose deliberately between renewing, renegotiating, re-tendering and ending the contract.
If you are leaving, plan the exit as carefully as the start. Check what the contract says about transition assistance, return of data and assets, transfer of knowledge and any staff transfer rules that apply to outsourced services. A supplier who knows it is losing the business has little incentive to help, which is why exit obligations belong in the contract from the beginning.
Common pitfalls
- No single owner, so every party assumes someone else is watching the contract.
- Signed contracts stored where only the legal team can find them.
- Automatic renewals that nobody noticed until the notice period had passed.
- Informal changes agreed by users and discovered only when the invoice arrives.
- Reviews that look only at the supplier and never at the buyer's own obligations.
