The headline figure on the HMRC contact center deal is hard to ignore.
A $670 million contract, awarded to Capgemini with NiCE CXone as the CCaaS engine, covering eight years of service delivery for one of the UK's most politically exposed public sector organizations.
When you include VAT, that number climbs closer to $814 million.
Beneath the headline, though, is a more interesting story; one about how enterprise CCaaS procurement actually works at the highest level, who gets in the room, and why the same names keep coming out on top.
The context that made this deal necessary is about as stark as procurement context gets.
A 2024 National Audit Office report found that HMRC's customer service had deteriorated badly, with taxpayers facing average telephone wait times of nearly 23 minutes in the first 11 months of the 2023-24 tax year.
More damaging still, an estimated 72% of those calls were driven by failure demand: people calling because a process had broken down, not because they needed genuine assistance.
The NAO's conclusion was that taxpayers were being “let down.”
For HMRC, in many ways, this is as much about repairing the company’s reputation, as it is about implementing fresh technology.
A Field of Thirteen, Down to Two
According to the UK government's official tender notice, the procurement process drew significant interest before narrowing sharply, with the final decision coming down to two vendors: NiCE and Genesys.
That outcome is, by now, fairly familiar in mega-enterprise CCaaS procurement. Despite the entry of AWS, Microsoft, and Salesforce into the contact center market – and the genuine momentum each has built – deals of this complexity tend to resolve down to the same two names.
Blair Pleasant, President and Principal Analyst at COMMfusion, is careful not to overstate what that means for the wider market:
“I think there's still room for others. HMRC had some very specific requirements for what it was looking for, and I think NiCE and Genesys were the only real options.”
“But in general, I think there's still more players in the market who can serve large enterprises.”
Pleasant is right that the CCaaS market isn't a closed shop. Five9, Talkdesk, and Content Guru are all landing larger deals than they were a few years ago.
However, at the tier HMRC was operating in, the procurement criteria alone did a lot of the filtering.
According to the contract notice, bidders were required to carry at least $190 million in annual CCaaS revenues, and the contract couldn't account for more than 10% of a supplier's total CCaaS business.
Those conditions eliminated most of the market before a presentation was made.
The analyst validation that underpins both vendors' positions at that tier is well documented.
Both NiCE and Genesys were named Leaders in the 2025 Gartner Magic Quadrant for Contact Center as a Service, for the 11th consecutive year each.
The Forrester Wave for CCaaS Platforms Q2 2025 tells a similar story, with NiCE ranked first in Strategy (4.14/5), and Genesys first in Current Offering (3.98/5).
At procurement committees where getting the decision wrong carries real political consequences, that kind of sustained, third-party validation carries more weight than it might in a lower-stakes technology purchase.
Where the Hyperscalers Stand
The HMRC process is also a useful reference point for where AWS, Microsoft, and Salesforce actually sit in the enterprise CCaaS market right now, which is somewhat short of where their overall scale might suggest.
Despite these hyperscalers making big CCaaS plays in recent times, there are still obvious shortcomings
Salesforce only launched native voice for its contact center offering at Enterprise Connect 2026, while Microsoft failed to appear in the 2025 Gartner Magic Quadrant evaluation at all.
AWS, however, is seemingly breaking the mold. The vendor is named a Leader in both the Gartner MQ and the Forrester Wave, recognized for its GenAI capabilities and consumption-based pricing.
Pleasant provided her own views on the reasons behind the varying fortunes of these would-be CCaaS powerhouses:
“Microsoft doesn't have the same level of capabilities [as NiCE and Genesys], and it certainly doesn’t have the experience... HMRC was looking for the company to have a certain amount of revenue.
“Both Microsoft and Salesforce have the required revenue that HMRC was looking for. But if you're looking just at the CCaaS piece, then they certainly don't."
What's missing for most of the hyperscalers is reference deployments.
