A practical guide to understanding what HMRC really wants and how to build a winning response.

The complexity behind cryptoassets

This tender isn't just about providing software.

It's about tackling sophisticated crypto-enabled crime.

HMRC needs robust solutions that can help trace, investigate and prevent the misuse of cryptoassets linked to criminal activities.

The contract covers two separate lots, one focusing on larger volumes and the other on smaller.

Each lot requires licenses for tracing solutions, forensic investigative support, API calls and training for HMRC's team.

Don't just sell software. Sell capability.

Every bidder can offer licenses and API calls.

What HMRC really wants is capability.

They need solutions that empower their investigators to effectively combat financial crime.

That means more than just tools.

It's about integrating those tools into HMRC's workflow to enhance their investigative power.

If I were writing this tender, I'd focus on how my offering translates into real-world impact for their investigations.

Think about what HMRC worries about

HMRC is tasked with fighting complex crimes that evolve rapidly.

They need partners who can keep pace.

If I were evaluating bids, I'd look for evidence that a supplier understands the fast-paced nature of crypto crime.

Consider these questions:

  • How quickly can your tool adapt to new threats?
  • What measures do you have in place to ensure compliance and security?
  • How does your training programme equip HMRC investigators to stay ahead?

These are the concerns I'd address head-on in my submission.

Pay attention to what they say

HMRC is clear about the need for forensic capabilities and courtroom-grade evidence.

They need solutions that can handle everything from automated triage to advanced visualisation.

This isn't just about providing data.

It's about delivering insights that lead to successful prosecutions.

I'd ensure to highlight how my solution supports each of the capabilities HMRC is looking for, with concrete examples.

Evidence always beats promises

One thing I noticed when I worked in the public sector was that very few bidders backed up their claims.

If you have evidence, use it.

I'd include:

  • Case studies demonstrating successful investigations using your tools
  • Testimonials from other law enforcement agencies
  • Metrics on the accuracy and reliability of your solutions
  • Examples of how your training has upskilled other investigative teams

That's what I'd focus on to differentiate my bid.

Navigating the Lot strategy

With two lots available, each bidder has to decide where they can genuinely deliver.

HMRC has made it clear that no supplier will be awarded more than one lot.

That means you need to carefully consider where your strengths lie.

If your solution is better suited to higher volumes, target Lot 1.

If you excel in more niche, tailored support, Lot 2 might be your best bet.

Don't spread yourself too thin by bidding for both without a clear strategy.

Consistency over the contract term

Winning the contract is just the first step.

The real challenge is delivering consistently over the two or three years.

I'd want to know how you'll maintain service levels amidst staff changes, technological updates and evolving threats.

Think about:

  • Your approach to recruitment and training
  • How you handle updates and upgrades to your software
  • Your protocols for ensuring compliance and data security

These are the details that reassure a buyer over the long term.

One thing I'd keep reminding myself

Remember, this isn't just about selling a service.

You're contributing to a national effort to combat financial crime.

I'd keep asking myself, "How does my offer make HMRC's job easier?"

Every part of your submission should answer that question.

Common mistakes

Avoid submissions that:

  • Focus solely on the technical specs of the software
  • Ignore the need for forensic-grade evidence
  • Neglect the importance of training and upskilling
  • Lack concrete examples of past success
  • Don't address security and compliance concerns
  • Overlook the specific requirements of each lot
  • Fail to show understanding of HMRC's operational needs
  • Promise more than can be realistically delivered

My Final Thoughts

HMRC is looking for partners who bring more than just technology.

They need solutions that integrate seamlessly and support their investigative efforts.

With a total estimated value of £3,933,000 over the contracts, the stakes are high.

Given the two-year duration with the potential for extension, consistency and capability are key.

Your written submission carries significant weight — focus on how your offering meets HMRC's complex needs and supports their mission long-term.

Thanks for reading.

I hope this guide has helped make public procurement feel a little less daunting. If it has, then it's done its job.
