What should I do if the supplier has changed the terms without highlighting them?

Request a 'redline' or 'mark-up' version from the supplier that shows every change made since the last version. If they refuse, you must perform a side-by-side comparison yourself to ensure you aren't agreeing to unfavourable terms by default.

Can I negotiate terms in a standard renewal agreement?

Yes. A renewal is a new contract negotiation. If you find clauses that have changed to your detriment, you have the right to request they be reverted to the original terms or amended to a new middle ground before signing.

Why do suppliers change terms during a renewal?

Suppliers often update terms to account for rising operational costs, changes in law, or to standardise their client base onto a single, newer set of terms that simplifies their own administration and reduces their risk.

Comparing Terms in a Renewed Supplier Agreement

11 September 2026 · 3 min read

When a supplier sends over a renewal contract, it is rarely a simple carbon copy of the previous version. Even if the salesperson claims the terms are the same, the fine print often reveals adjustments to pricing structures, service level agreements, or liability limits. Comparing terms in a renewed supplier agreement is a critical step in protecting your business from 'contract creep'—the gradual erosion of value over time. This guide outlines a systematic approach to identifying these changes before you sign.

Prioritise Financial and Commercial Variations

The most obvious changes are financial, but they are not always presented as a simple price hike. Suppliers may maintain the base price while adjusting the underlying fee structure or introducing new service charges. Look closely at how the renewal handles volume discounts and tiered pricing, as these are frequently recalibrated to the supplier's advantage during a renewal cycle.

Check the payment terms specifically. A shift from 30-day to 14-day terms can significantly impact your cash flow. If the renewal includes an automatic annual increase tied to an index like the RPI or CPI, ensure the cap on that increase remains reasonable and consistent with your original agreement.

Audit Service Levels and Deliverables

Operational terms are often where subtle 'downgrades' occur. A renewed agreement might broaden the definition of 'excused downtime' or lengthen the response window for technical support. If your business relies on specific performance metrics, you must verify that these benchmarks have not been diluted in the new version.

Pay particular attention to the following areas where terms often shift:

Response times for critical support tickets and general enquiries.
Uptime guarantees and the compensation structure for service failures.
The scope of included services versus those now classified as 'add-ons'.
Termination notice periods and the associated exit fees.

Watch for Legal and Risk Allocation Changes

Suppliers frequently update their standard terms to reflect changes in their own insurance requirements or legal advice. This often results in a shift of liability towards the customer. When comparing terms in a renewed supplier agreement, look for new indemnity clauses or changes to the limitation of liability cap.

Data protection and compliance clauses are also subject to frequent updates. Ensure the new agreement still aligns with your own regulatory requirements, particularly regarding how data is stored, processed, and deleted at the end of the contract term. Manual comparison can be difficult here, as legal teams often rephrase entire sections without changing the intent, or change a single word that fundamentally alters the meaning. Using a tool like Jittan DocumentChecker can help you compare documents and schedules to spot these mismatches and omissions quickly.

Reviewing every line of a renewal ensures that your business maintains the same protection and value it originally negotiated. Taking the time to compare terms properly prevents unexpected costs and service issues later in the contract term.
