How to evaluate your Finance Function

Most CEOs and business owners form a view of their finance function’s performance based on a single indicator: whether the management accounts arrive on time. This is an important indicator but a narrow one. A finance function can produce management accounts within five working days of month-end every month and still be failing to deliver on its broader responsibilities — missing early warning signals on cash flow, producing technically flawed statutory accounts, leaving controls gaps that create financial risk, or failing to provide the commercial analysis that the business needs to make better decisions.

This guide provides a structured diagnostic framework for CEOs, owners and Finance Directors who want to assess whether their finance function is performing at the level the business needs. It covers the eight dimensions of finance function performance that matter most, the specific indicators that signal strength or weakness in each, and the actions that follow from an honest assessment.

Why Finance Function Assessment Is Difficult from the Inside

Assessing your own finance function is genuinely difficult for several reasons. The most important is that the CEO or owner who is not themselves a qualified finance professional typically lacks the technical framework to distinguish between a finance function that is performing well and one that is performing adequately — the management accounts arrive on time, the external accountant does not raise obvious concerns, and nothing has obviously gone wrong. The absence of visible failure is interpreted as evidence of strong performance, when it may simply be evidence of an absence of visible failure.

The second difficulty is that the Finance Manager or Financial Controller who is responsible for the finance function has an obvious interest in presenting it favourably. This is not necessarily dishonest — most finance professionals genuinely believe their function is performing well, and many are right. But the FC who tells the CEO that the management accounts are as good as they can be, the controls are as strong as they need to be, and the team is as capable as the business needs is not in a neutral position, and the CEO who takes that assessment at face value without a more structured review is missing the only perspective that is genuinely independent.

The solution is to use a structured diagnostic framework that covers the dimensions of finance function performance most relevant to the specific business at its current stage, and to obtain at least one external perspective — from the external auditor, from a fractional FD, or from a specialist finance recruiter who has visibility of comparable finance functions across many businesses — to supplement the internal assessment.

The Eight Dimensions of Finance Function Performance

1. Close Quality and Timeliness

The management accounts are the primary output of the finance function and the primary indicator of its technical performance. Assess: how many working days after month-end are the management accounts produced? Is that consistent month to month, or does the close time vary significantly? Do the management accounts include a prior-year comparative and a budget comparison? Is there a written commentary that explains the financial performance in commercial terms rather than simply presenting numbers? Are the balance sheet reconciliations completed as part of the close, with all material reconciling items explained?

Strong performance: management accounts produced within six to eight working days, consistently, with prior-year and budget comparatives and a clear written commentary. Balance sheet fully reconciled each month. Weak performance: management accounts taking twelve to fifteen days or more; significant variation in close time month to month; no or minimal written commentary; balance sheet reconciliations not completed monthly or containing unexplained items that carry over for multiple months.

2. Cash Flow Forecasting

The finance function’s cash flow forecasting capability is often the first thing to fail in a business under financial pressure — precisely when it is most needed. Assess: does the finance function produce a rolling cash flow forecast, and how far forward does it look? Is the forecast at a level of granularity that allows the business to identify cash pressure before it becomes critical — showing inflows and outflows at a weekly level for the next four to six weeks, not just a monthly average? How accurate has the forecast been against actuals in recent months?

Strong performance: rolling thirteen-week cash flow forecast produced weekly, with accuracy within 5–10% on a four-week horizon. Cash flow surprises are flagged by the finance function before they appear, not discovered by the CEO or bank. Weak performance: no rolling forecast; monthly P&L used as a proxy for cash management; cash surprises regularly discovered late and communicated reactively.

3. Financial Controls

Financial controls are the mechanisms that prevent errors, detect fraud and ensure that the financial records accurately reflect the transactions of the business. They include: segregation of duties (different people authorise, process and reconcile transactions); payment authorisation limits and dual approval for payments above a threshold; purchase order matching; payroll reconciliation; bank reconciliations completed and reviewed by someone other than the person who processes transactions.

Strong performance: documented control framework covering the key transaction types; segregation of duties in place for payments; bank reconciliations reviewed by a senior person; payroll reconciliation performed monthly. Weak performance: one person authorises and processes payments without secondary review; bank reconciliations performed irregularly or reviewed by the same person who processes transactions; no documented control framework; material control gaps identified in audit management letters that have not been addressed.

4. Statutory Accounts and Audit Management

The annual statutory accounts and the audit that accompanies them (where the business is audit-eligible) are the most technically demanding outputs of the finance function. Assess: are the statutory accounts filed on time and without extension? Does the audit management letter contain material control or accounting weaknesses? Has the time taken to complete the audit increased in recent years? Are the statutory accounts technically accurate under FRS 102 or IFRS, including the disclosures required for the specific entity type?

Strong performance: statutory accounts filed within three to four months of year-end; clean audit opinion; audit management letter containing only minor points; audit completed within four to six weeks of fieldwork commencement. Weak performance: statutory accounts filed close to the nine-month deadline; qualified or emphasis of matter audit opinion; audit management letter containing material control weaknesses or accounting adjustments required by the auditor.

5. Commercial Financial Analysis

Beyond the monthly management accounts, the finance function should be producing the commercial financial analysis that supports the decisions the management team is making. Assess: when a significant commercial decision is being made — a new product launch, a market expansion, an acquisition, a pricing change — does the finance function provide financial modelling that quantifies the financial impact and the risks? Does the management team regularly use financial analysis produced by the finance function to inform commercial decisions, or do they make commercial decisions and then ask finance to confirm the numbers afterwards?

Strong performance: finance function proactively provides financial analysis for commercial decisions; management team habitually uses finance function modelling as an input to major decisions; budget and forecast reflect the commercial strategy. Weak performance: finance function produces historical reporting but does not proactively contribute to forward-looking commercial decisions; commercial decisions made without financial modelling; budget prepared as a projection of last year rather than as a financial translation of commercial strategy.

6. Team Capability and Development

The finance team’s collective capability — the qualifications, experience and development trajectory of the people in it — is the primary determinant of finance function performance over the medium term. Assess: what qualifications does each member of the finance team hold, and are those qualifications appropriate for the scope of the role? Are the team members developing — progressing toward qualification, taking on increasing scope, being developed for the next level? Is the turnover in the finance team higher than in the rest of the business?

Strong performance: senior finance professional (FC or above) is ACA, ACCA or CIMA-qualified; team members below FC level are studying or have studied; turnover in the finance team is at or below the business average; the FC has a clear view of each team member’s development and provides regular structured feedback. Weak performance: senior finance professional is not professionally qualified; high turnover in the finance team; no structured development programme; team members are in roles above their capability with no plan to close the gap.

7. Technology and Systems

The finance function’s technology stack — the accounting software, the reporting tools, the payroll system, the purchase ledger platform — should be fit for the current scale and complexity of the business. Assess: is the accounting software appropriate for the business’s current transaction volume, entity structure and reporting requirements? Is the finance team using spreadsheets to compensate for gaps in the accounting system? Has the technology been reviewed within the last three years?

Strong performance: accounting software appropriate for current scale (Xero, Sage, NetSuite, SAP depending on size); minimal manual data entry; consolidation tool in place where the business has multiple entities; payroll managed through integrated or well-reconciled payroll software. Weak performance: outgrown accounting system requiring significant manual workaround; consolidation performed in spreadsheets; significant time spent by qualified staff on data entry tasks that should be automated or handled by system integrations.

8. Strategic Financial Support

At businesses of £15m and above, the finance function should be providing strategic financial support that goes beyond monthly management accounts — input to the annual strategic planning process, long-range financial modelling, capital allocation analysis, scenario planning for major strategic decisions. Assess: is the finance function involved in the strategic planning process, or does it receive the completed plan and produce a financial translation of it? Does the FD or FC present the strategic financial position to the board, or does the CEO present it without finance input?

Strong performance: FD leads the finance input to the strategic plan; long-range financial model maintained and used in board-level strategic discussions; finance function proactively challenges strategic decisions where the financial model does not support them. Weak performance: finance function receives strategic plan and produces a budget from it; no long-range financial model; FD not present at or not contributing substantively to strategic planning discussions.

Scoring Your Finance Function

Count your Strong, Needs Development and Weak scores. A finance function with five or more Weak ratings has structural issues that represent material risk to the business and require urgent attention — either through recruitment to address capability gaps, investment in technology, or management intervention to address the process failures. A function with three or more Needs Development ratings is performing adequately but below what the business is capable of with modest investment in the right areas. A function with six or more Strong ratings is performing well and the investment priority should be ensuring the current team is compensated and developed to maintain that performance.

What to Do With the Assessment

An honest assessment of your finance function against these eight dimensions will typically reveal one of three situations. The first is a capability gap — the finance function is failing in one or more dimensions primarily because the most senior finance professional does not have the skills or experience to deliver at the level the business needs. The solution is almost always a recruitment decision: either replacing the current senior finance professional or adding a more senior person above them who can provide the capability that is missing. See the Financial Controller and Finance Director recruitment pages for the relevant roles.

The second situation is a structural gap — the finance function has the right people but the wrong structure, so the capable FC is spending time on tasks that should be handled by a junior team member, or the strategic financial planning dimension is not being delivered because the FC’s time is consumed by the close and the audit. The solution is a structural change: adding a Management Accountant to free up the FC’s time, or adding an FD or Fractional FD to take the strategic financial leadership dimension from the FC. See the Finance Team Structure guide for the recommended structures at each revenue stage.

The third situation is a resource gap — the finance function has the right structure and the right people, but they are operating without the technology, the time or the organisational support to perform the way their capability would allow. The solution here is an operational investment rather than a people change: upgrading the accounting system, investing in reporting tools, reducing the non-finance demands on the finance team’s time, or increasing the budget for external advisory support where the in-house team needs it.

The External Auditor’s Perspective

If your business is subject to statutory audit, the external auditor’s management letter and the conduct of the audit itself provide valuable evidence about finance function performance. Auditors who spend more fieldwork time than expected, raise more queries than in previous years, or produce a management letter with material points are signalling finance function weakness — often more clearly than the internal assessment. The management letter is particularly valuable because it reflects the auditor’s professional assessment of the control environment and accounting quality, drawn from a systematic review of the financial records.

Review the last three years of audit management letters and assess whether the points raised are: new and significant (indicating deterioration in the control environment or accounting quality); the same as the previous year (indicating that prior points have not been addressed); or resolved and not recurring (indicating improvement). A finance function that generates the same audit management letter points year after year, without addressing them, is a finance function whose internal assessment of its own performance is significantly more generous than the external auditor’s.

If your business is below the audit threshold — currently £10.2m turnover, £5.1m balance sheet total and 50 employees (two of three must be exceeded to require audit) — the external accountant’s feedback on the year-end accounts preparation is the closest equivalent. An external accountant who consistently requires significant adjustments to the accounts, or whose preparation time has increased relative to previous years, is providing an implicit assessment of finance function quality that the CEO should take seriously.

Benchmarking Against Comparable Businesses

One of the most useful frames for finance function assessment is comparison with comparable businesses — those at a similar revenue stage, in a similar sector and with a similar ownership structure. What does the finance team at a comparable business look like? How many people, at what seniority levels, with what qualifications? What does the management pack look like — how many pages, how many working days after month-end, how much written commentary? What does the audit timeline look like?

Accountancy Capital places finance professionals across hundreds of businesses at every revenue stage each year. When a CEO asks us whether their finance function is structurally right for the business’s current scale, we can give a specific answer based on what we see across comparable businesses — not a generic benchmark from a survey, but a live market view from active placement data. This is the most valuable single input to a finance function assessment that most CEOs do not think to ask for, because they do not realise that a specialist finance recruiter has that comparative visibility. It is always available through a direct conversation with an Accountancy Capital consultant, with no commitment or cost.

The benchmarking conversation typically takes twenty to thirty minutes and covers: the current finance team structure and headcount; the close timetable and management accounts format; the audit management arrangement; the financial planning and analysis capability; and the technology in use. Against those inputs, we can give a specific view of where the current structure is appropriate for the business’s stage and where it is under-resourced, over-structured or misaligned to what businesses at the same scale are doing effectively.

Acting on the Assessment: A Prioritised Approach

Once the assessment is complete, the natural temptation is to address all the weaknesses simultaneously. This is rarely the right approach — it creates too much change too quickly, overloads the existing finance team and makes it difficult to attribute improvement to specific actions. A prioritised approach that addresses the most material weaknesses first, stabilises the function, and then moves to the secondary priorities is consistently more effective.

The priority order for most businesses is: financial controls first (a material control gap is the highest-risk weakness and the most urgent to address); close quality and cash forecasting second (these are the outputs the management team depends on most frequently); team capability third (the most sustainable quality improvement comes from having the right people in the right roles); and commercial financial analysis and strategic support last (these are high-value but require a stable operational foundation before they can be delivered consistently).

The most common mistake in acting on a finance function assessment is to start with the highest-profile or most visible weakness — often the management accounts quality — without addressing the underlying structural cause. Management accounts that are consistently late are almost never fixed by asking the FC to work harder. They are fixed by adding a Management Accountant to support the close, by upgrading the accounting system to reduce manual processing time, or by addressing the transactional processing backlogs that delay the close. Diagnose the root cause before implementing the solution.
