The government platform created to help firms navigate UK trade in light of Brexit will be supported by a new tech supplier, following a procurement process to replace incumbent Fujitsu
HM Revenue and Customs has picked Danish tech outfit Netcompany as its chosen partner for the digital service enabling trade between Great Britain and Northern Ireland – replacing Fujitsu as the platform’s core provider
Newly published commercial information reveals that, on 16 December, the department entered into an initial five-year agreement with Netcompany to serve as the “service provider for the Trader Support Service (TSS)”. The deal – which is valued at about £294m, inclusive of VAT – can potentially be extended for a further two years, which would take the ultimate end date to late 2032.
During the duration of the contract, the supplier will support a service that is comprised of “two key elements”, including “a digital platform system to enable traders to submit information to meet requirements under the Windsor Framework”. This online system is accompanied by a “customer support service, providing information and guidance for businesses on how to submit compliant declarations and the steps they need to take to comply with regulations”, according to a commercial notice released on GOV.UK.
In winning the deal to support HMRC in delivering these offerings, Netcompany beat off two other bidders, the notice indicates. The procurement process was launched nine months ago to identify a replacement for the incumbent providers: a consortium led by Fujitsu, and also featuring consultancy McKinsey and outsourcer HGS.
These firms have been under contract with HMRC since 2021, in a deal that has been incrementally extended to run until the end of this year. Since first being signed, the value of the deal has more than doubled to a total of over £600m.
Bids to replace the Fujitsu-led arrangement were limited to firms or consortia with at least £50m in annual turnover.

TSS was first launched in 2020 and provides firms with training and support in adapting to the post-Brexit Windsor Framework measures that now govern trade between Northern Ireland – which remains in the EU single market for goods – and the other three countries of the UK. The free-to-use GOV.UK-based service can also automatically complete customs declarations and other requirement documents on behalf of users.
Headquartered in Copenhagen, Netcompany has become a major government digital supplier in recent years, with one of its first significant engagements being its work to help develop and support the health service’s contact-tracing app rolled out during the Covid pandemic.
Since the start of the 2020s, the firm has won about £600m in public sector deals, online procurement records on GOV.UK indicate. As well as a number of other NHS contracts, this includes some other major recent wins with HMRC, encompassing a £135m arrangement last year for the delivery of “professional services to allow for the creation of multiple disciplinary and agile delivery teams across HMRC’s digital delivery centres”. This was followed in November 2025 with a potential £20m-plus engagement to help deliver a “new computerised transit system” for the department.
The company was also recently chosen to work with the Scottish Government to develop a national app to support proof-of-age processes and the delivery of public services.
