Finance Operating Model Friction: Why Growing Businesses Outgrow Their Finance Function
Merixa Insights · Finance Transformation & Team Build
Why growing businesses outgrow their finance operating model — and how misaligned outputs, expanding scope, and unclear ownership reduce the finance function’s commercial contribution.
In practical terms, institutional friction forms when the finance function is still organised around the reporting needs, decision cycles, and ownership model of an earlier version of the business. The team may be capable, and the data may be accurate, but the operating model no longer produces financial information in the form, timing, or governance structure that leadership now requires.
When a growing business finds that finance is producing accurate information but not quickly enough, completely enough, or in the form leadership needs, the first response is often to question the team or the technology. In many cases, the deeper issue is neither.
The deeper issue is often the operating model: the architecture of how financial work is structured, sequenced, owned, and reviewed. It may have been designed for a smaller, simpler business and never formally redesigned to match what the organisation has become.
This is primarily an architectural problem, not only a control or process-efficiency problem. It operates at the level of how the function is structured to deliver its outputs, not at the level of whether individual controls within it are proportionate or whether individual processes are appropriately automated. Two structural issues at this architectural level most consistently produce a finance function whose commercial contribution falls short of what the business's scale now demands.
Issue one — output architecture misaligned with commercial decision cycles
The finance operating model determines not only what the function produces, but when those outputs are available, who owns them, and whether they match the decision cycle of the business.
In many organisations, the sequencing of financial outputs — record-to-report, management reporting, cash flow visibility, and board reporting — was calibrated to a business with lower revenue, fewer entities, simpler decisions, and fewer external reporting demands.
The commercial consequence is specific and observable. Management information that takes fourteen elapsed days to produce may be too slow for a business making active monthly resource-allocation decisions.
A cash flow position refreshed monthly from accounting data alone may not provide the liquidity visibility required by a lender-monitored business. A reporting architecture built around entity-level statutory outputs rather than commercial-unit contribution analysis is not answering the questions the leadership team is asking when it meets to make capital decisions. These are not necessarily capability failures. They are often operating-model failures — and the distinction matters because the intervention they require is a redesign of how the function is structured to produce its outputs, not an improvement in how efficiently it executes the structure it already has.
The finance operating model sits between the data the business generates and the information leadership needs. When that model was designed for an earlier version of the business, team capability alone cannot close the gap.
Issue two — finance scope expanding without governance redesign
The second issue operates at the boundary of the finance function rather than at its internal architecture. As businesses scale, the scope of what the finance function is expected to contribute expands — from statutory compliance and management reporting to business partnering, investor relations support, treasury management, and strategic financial analysis. Each expansion may be commercially rational. What seldom accompanies it is a deliberate redesign of the operating model to accommodate the new scope — a structured decision about what the function's capacity will be redirected from, what new capability it needs to develop, and how the governance boundaries between its expanding responsibilities will be maintained.
The consequence is a finance function that is under-resourced for its expanded scope while remaining over-committed to activities that could be automated, delegated, redesigned, or removed.
The higher-value contribution of senior finance professionals is usually found where financial expertise is applied to commercial judgement: interpreting performance, testing decisions, explaining risk, and translating financial information into usable management insight. An operating model that consumes senior finance capacity in work below that contribution threshold is not only inefficient. It is commercially costly because the analysis leadership needs is produced by the same capacity that operational overload is consuming.
Questions that identify the friction
- At the current scale of the business, does the finance function produce management information in the timing, format, and ownership structure required by leadership decisions?
- When finance scope last expanded — through a new entity, reporting requirement, funding relationship, or board expectation — was the operating model redesigned, or was the additional work absorbed into existing capacity?
- What proportion of senior finance time is spent on work requiring financial expertise and commercial judgement, and what proportion is consumed by work that sits with them only because the operating model has not allocated it elsewhere?
- If you were designing the finance operating model today for the business as it currently exists, what would you build differently, and why has that change not yet been made?
The gap between the current operating model and the model the business now requires is the measure of the friction being created. The diagnostic work begins at that architectural level. Individual process efficiency and control calibration may still need attention, but they are separate questions from whether the finance function is structured correctly for the business it now serves.
