Protecting Your IBM Z Investment: Why Third-Party Software Renewals Should Never Be Left Until the Last Minute
27 July 2026 - 3 Minute Read
For decades, IBM Z has been the platform organisations have trusted to run their most business-critical applications. It remains unmatched in terms of resilience, security, performance and availability, continuing to power banks, insurers, retailers and governments around the world.
Yet today, one of the biggest threats to that investment isn't the platform itself.
It's the cost of renewing third-party software.

A Changing Commercial Landscape
Over the past few years, we've seen significant changes in the way some enterprise software vendors approach licensing and renewals. Following acquisitions and changes in ownership, many customers are finding that longstanding commercial agreements no longer deliver the value they once did.
For organisations running IBM Z, this can result in unexpected and substantial increases when renewal time arrives.
We're currently helping a customer prepare for a major third-party software renewal that is still more than twelve months away. Early analysis suggests that, without careful planning, annual licensing costs could increase from approximately £3 million to almost £18 million.
Every organisation's licensing position is different, but one thing is becoming increasingly clear:
Leaving renewals until the last minute is no longer an option.
Procurement Can't Solve This Alone
Most procurement teams are highly skilled negotiators.
However, very few are specialists in IBM Z software licensing.
Mainframe software estates are often the result of decades of investment, acquisitions, upgrades and changing business requirements. Understanding exactly what is deployed, what is actually being used, what contractual rights exist and what alternatives are available requires specialist technical and commercial knowledge.
By the time a renewal quotation reaches the procurement team, many of the opportunities to influence the outcome have already passed.
Protect Your Existing Investment
One of the biggest concerns we have is seeing organisations question the future of their IBM Z platform because of a software renewal.
That's the wrong conversation.
IBM Z continues to provide exceptional reliability, scalability and long-term value. Replatforming business-critical applications purely because of a third-party software renewal can introduce years of risk, disruption and significant cost.
Migration projects often involve:
- Replacing proven applications
- Rewriting decades of business logic
- Data migration and testing
- Staff retraining
- New infrastructure
- Increased operational risk
The total cost of replatforming frequently exceeds the savings organisations hope to achieve.
Protecting your existing investment should always be the first consideration.
Start Planning Early
The most successful renewals don't begin when the quotation arrives.
They begin 12 to 18 months beforehand.
Early planning allows organisations to:
- Understand their software estate
- Review actual product usage
- Validate licensing positions
- Identify commercial options
- Build a negotiation strategy
- Reduce unnecessary expenditure
- Avoid being forced into last-minute decisions
Time creates options, waiting removes them.
