When to Bring in External Treasury Implementation Resource

Every organisation that undertakes a treasury management system implementation faces the same question at some point: do we have the right people to deliver this, or do we need external help? The answer is rarely straightforward, because the question is usually asked too late — after the programme is already in difficulty — rather than at the planning stage when it is most useful. Getting the resource model right before the programme starts is one of the highest-return decisions a CFO or Group Treasurer can make.

What Internal Resource Can Realistically Deliver

Most corporate treasury teams have the domain knowledge to define what they need from a treasury management system. They understand their cash management processes, their FX exposure, their payment flows, their reporting requirements. That knowledge is essential and irreplaceable — a TMS implementation that is configured without it will not serve the business.

What internal treasury teams typically do not have is the system-specific implementation experience to translate that knowledge into correct TMS configuration, manage the technical integration work, design and execute UAT, and manage the bank connectivity process. These are specialist skills that come from having done this before on multiple programmes — they cannot be acquired on a single implementation without significant risk to the programme.

Signs That External Resource is Needed

The need for external implementation resource is clearest in four situations. First, where no one on the internal team has implemented this specific system before. The learning curve on a complex treasury management platform is measured in months, not weeks, and it is an expensive learning curve to run on a live programme.

Second, where the internal team's capacity is constrained by BAU responsibilities. TMS implementations require sustained, focused effort over an extended period. Treasury teams that are also running day-to-day operations, managing month-end close, and handling the organisation's live treasury requirements do not have the bandwidth to also drive a complex implementation to a high standard.

Third, where the programme has specific technical requirements — ERP integration, bank connectivity, SWIFT configuration — that sit outside the treasury team's technical expertise. These are areas where errors are expensive and where the wrong configuration can create problems that persist long after go-live.

Fourth, where the programme is in trouble and the internal team does not have the diagnostic experience to identify root causes and drive recovery.

What to Look for in External Resource

The most important question when evaluating external treasury implementation resource is not which firm they work for. It is how many implementations of this specific system they have personally delivered. Treasury implementation is a skills discipline, not a credentials one. A consultant who has delivered three or four full TMS implementations will outperform a more junior consultant from a larger firm who has been on programmes but has not held primary delivery responsibility.

Relevant experience means: they have done the configuration, managed the UAT, resolved bank connectivity issues, and been present at go-live on programmes of comparable complexity. Not that they have been on a team where someone else did these things.

Speed of availability matters. TMS programmes frequently identify resource gaps mid-programme, when the immediate need is someone who can start within days, not someone who can be onboarded in six weeks. External resource that requires a lengthy procurement process or a long notice period does not solve the problem.

Engagement Models

External treasury implementation resource is typically engaged in one of three ways. As a direct interim placement — a consultant embedded in the programme team for the duration of a defined phase or the full programme. As specialist advisory resource — brought in for specific technical challenges such as bank connectivity or ERP integration rather than end-to-end delivery. Or as project rescue resource — senior implementation experience deployed at short notice to diagnose and resolve a programme in difficulty.

The appropriate model depends on where the gap is. For programmes that have not yet started, full-programme resource from the beginning is the most efficient approach. For programmes already underway with specific identified gaps, targeted specialist resource is usually more appropriate than bringing in a full additional team.

Day Rates and What to Expect

Senior treasury implementation consultants are priced at £850–£1,100/day in the current UK market, reflecting the scarcity of the skills and the seniority required to deliver complex programmes. This is materially below the equivalent resource through a Big 4 or large consulting firm, where the day rate reflects firm overhead as much as the consultant's experience.

RG Treasury provides senior interim treasury implementation consultants for every stage of a TMS programme. Our consultants are available within one to two weeks of engagement confirmation. Contact Sales@rgtreasury.com to discuss your requirement.
