Independent treasury technology advisory informed by implementation and operational reality.
Lumin Treasury Consulting supports CFOs and treasury leaders who need confidence that treasury systems will remain effective in live operation, producing reliable visibility, robust controls and decision-ready reporting.
Lumin Treasury Consulting is led by Bisi Tishe, an independent treasury technology advisor focused on treasury systems, post-go-live environments and how systems behave in real operations.
The firm brings experience from treasury system implementation and live production environments, helping organisations align design decisions with long-term operational performance.
About Bisi Tishe
Bisi Tishe is the founder of Lumin Treasury Consulting, an independent advisory practice built around a problem most treasury teams recognise but few talk about openly: systems go live, projects close, and then the real operational work begins.
With over 20 years in treasury operations and direct experience across five full life-cycle FIS Quantum implementations and upgrade projects, Bisi has spent the majority of her career on the operational side of treasury technology. Not just delivering systems, but working in them, stabilising them, and helping teams build genuine confidence in how they run day to day.
Her hands-on experience spans FIS Quantum, FIS Integrity, and OpenLink Findur, across implementation programmes, live operational support, controls design, reporting, data structures, interfaces, reconciliations, and post-go-live process challenges. Over time, a clear pattern emerged: the problems that create the most operational risk are rarely present at go-live. They surface later, in audit findings, in manual workarounds that quietly become permanent, in reporting that works but cannot be explained, in teams that are cautious about touching a system that is technically live but not fully understood.
That pattern is the focus of Lumin's work. Rather than approaching treasury systems from a project or technical perspective, Bisi's focus is on how treasury technology behaves in real operational environments, where accounting deadlines, audit scrutiny, data quality, and operational pressure intersect with the controls and configurations inherited from implementation.
This operational perspective shapes both the advisory work delivered through Lumin and the practical insights shared through Lumin's published resources and training content, including a free corporate treasury course on ISO 20022, now attended by professionals across 26 countries, alongside published training content focused on treasury system implementation risks.
When treasury systems are live, but effectiveness is under pressure.
Lumin is often engaged after implementation, when responsibility transitions into operational ownership and real-world complexity begins to affect reporting confidence, control integrity or system reliability.
Operational effectiveness challenges
- Recurring operational incidents or inconsistent system behaviour
- Unclear ownership across Treasury, Finance and IT
- Manual workarounds increasing operational risk
- Reporting confidence weakening as operational volume grows
Implementation decisions under review
- Design choices not aligning with day-to-day treasury processes
- Testing outcomes not translating into stable production performance
- Interfaces or automation processes lacking resilience
- Control gaps becoming visible after programme completion
How Lumin views treasury technology
Treasury system effectiveness rarely deteriorates through a single failure event. More often, performance declines gradually as configuration complexity grows, ownership becomes fragmented or operational practices evolve without corresponding system alignment.
Treasury operating model first
Effective treasury technology begins with clear policy, governance and operating model alignment. System configuration, workflows and reporting structures should reinforce treasury practice, not shape it.
Practitioner-led judgement
Lumin’s advisory is informed by experience inside live treasury environments, not just project documentation. This means recommendations are shaped by how systems behave under real operational pressure: month-end deadlines, audit requests, data changes, interface issues and day-to-day treasury ownership.
Improving system effectiveness without creating dependency.
Clarify expected system behaviour
- Align treasury policy and operating model with system configuration
- Assess workflows, controls and reporting against operational demands
- Define ownership structures and decision governance
- Establish pragmatic improvement roadmaps
Strengthen live operational performance
- Diagnose root causes of recurring operational issues
- Improve interface reliability and process resilience
- Enhance reporting confidence and reduce manual dependency
- Introduce sustainable governance and monitoring practices
A focused diagnostic followed by structured advisory.
Engagements typically begin with a targeted diagnostic to identify key risks and improvement priorities across treasury system configuration, interfaces, controls or reporting. Advisory then proceeds through clearly defined scopes designed to strengthen long-term operational effectiveness.
For FIS Quantum environments, the standard entry point is the Quantum Health Check , a structured review designed to assess whether the system is operating with the confidence, control and resilience expected after go-live.
