What happened
The UK's HMRC awarded Capgemini a £37 million contract to migrate its Enterprise Tax Management Platform from SAP ECC 6.0 to S/4HANA, potentially extending a supplier relationship that began in 2004 to 28 years. The system handles over £800 billion in annual tax revenue and serves 40,000 users; the original Aspire contract cost £7.9 billion and generated £1.2 billion in combined profit for Capgemini and Fujitsu.
Why it matters
SAP ECC end-of-life is forcing large enterprises and governments into expensive, multi-year S/4HANA migrations—anyone working with SAP-dependent clients should expect prolonged consulting demand and budget pressure around these migrations, though this specific UK procurement story has little direct impact on Malaysian builders.
Discussion angle
Use this as a cautionary tale on vendor lock-in: HMRC has been with Capgemini for 22 years and counting, with contract costs ballooning far beyond original estimates—what does that tell us about evaluating lock-in when choosing enterprise platforms?
