Reviewing and Improving Finance Processes and Controls

Finance processes and controls are the infrastructure of a well-run business. When they work properly, they are largely invisible — transactions are processed accurately, approvals happen in the right sequence, management information is reliable, and cash moves in and out of the business as intended. When they fail, the consequences range from embarrassing errors in management accounts to significant fraud losses to audit qualifications that can derail a fundraise or acquisition. A fractional Finance Director reviews your existing finance processes and controls systematically, identifies the gaps that create the greatest risk, and implements practical improvements that strengthen the business without creating unnecessary bureaucracy.

For many SMEs, this process review is one of the first things a fractional FD undertakes when joining a business. It establishes a baseline understanding of how the finance function actually operates, identifies quick wins that can be delivered immediately, and creates a prioritised improvement plan for the medium term.

What a Finance Process and Controls Review Covers

A comprehensive review of finance processes and controls examines every area where financial transactions occur or financial information is produced. The scope typically includes the following areas.

Purchase-to-pay: How supplier invoices are received, authorised, coded, and paid. Who has authority to commit the business to expenditure, at what levels, and with what documentation. How the accounts payable ledger is maintained, aged, and reviewed. Whether payment runs are properly authorised and whether bank details for new suppliers are verified before any payments are made.

Order-to-cash: How sales are captured, invoiced, and collected. Whether credit checks are performed on new customers, whether credit limits are enforced, and whether the collections process is consistent and timely. How the accounts receivable ledger is aged and reviewed, and what escalation process exists for overdue accounts.

Payroll and expenses: How payroll is authorised and processed, whether the payroll authorisation chain is segregated from the payroll preparation function, and how new starters and leavers are handled. How employee expenses are submitted, authorised, coded, and processed, and whether the expense policy is clearly documented and consistently enforced.

Month-end close: The process by which financial transactions are cut off, accounts are reconciled, and management accounts are produced. How long the close process takes, which reconciliations are performed and by whom, and what review and sign-off steps occur before accounts are issued to management.

System access and segregation: Who has access to the accounting system and at what permission level. Whether the fundamental principles of segregation of duties are respected — particularly that the person preparing payments is not the same person authorising them. Whether access levels are reviewed when staff change roles or leave the business.

The Most Common Control Weaknesses in UK SMEs

Across many SME finance function reviews, certain control weaknesses recur with significant frequency. Recognising these patterns allows a fractional FD to investigate the highest-risk areas first and address them before they result in a loss.

Absence of Segregation of Duties

In small finance teams, it is common — and sometimes unavoidable — for one person to have end-to-end control of a financial process. The same individual sets up suppliers, processes invoices, and makes payments. This is the single most significant fraud risk in SME finance, because it means there is no independent check on any transaction. A fractional FD designs compensating controls that reduce this risk even where full segregation is not possible — for example, requiring the business owner to authorise payment runs above a certain threshold, or implementing automated duplicate payment detection in the accounting software.

Inadequate Invoice Authorisation

Many SMEs lack a formal purchase order or invoice authorisation process. Supplier invoices arrive and are paid without any documented check that the goods or services were actually received, that the price matches what was agreed, or that the expenditure was authorised by someone with appropriate authority. This creates risk both of fraud and of error — overpayments, duplicate payments, and payments for goods or services never received. Implementing a simple three-way matching process — purchase order, goods receipt note, and supplier invoice — eliminates the vast majority of accounts payable risk.

Bank Reconciliation Delays

Regular, timely bank reconciliation is the most fundamental financial control in any business. When bank reconciliations are performed infrequently or are consistently behind, errors and anomalies in the financial records accumulate undetected. Cloud accounting platforms have made daily bank reconciliation straightforward through automated bank feeds, and a fractional FD ensures that this basic control is operating consistently.

"The controls review was uncomfortable — there were things we hadn't thought about for years. But addressing them was straightforward once they were identified, and we all felt more confident in the business afterwards."

Implementing Improvements Without Creating Bureaucracy

A common concern when business owners hear about finance controls improvement is that the result will be an impractical bureaucratic process that slows the business down. This is a legitimate concern — poorly designed controls are worse than no controls because they get circumvented, and the false sense of security they create is actually more dangerous than acknowledged absence of control. A fractional FD designs controls that are proportionate to the risk, practical to operate, and consistent with the size and culture of the business.

For a £2m turnover business, appropriate controls look very different from appropriate controls for a £20m business. The FD calibrates the control framework to the business's actual risk profile and operational reality, not to a theoretical best practice benchmark that would be impractical to implement. The goal is not to pass an audit — though well-designed controls make audits straightforward — but to run a reliable, fraud-resistant finance function that produces trustworthy management information.

Documenting Processes for Resilience and Growth

An often-overlooked benefit of a finance process review is the documentation it produces. Most SME finance functions operate on institutional knowledge — processes exist in people's heads rather than in written procedures. When a key member of the finance team leaves unexpectedly, the disruption this causes is significant. Process documentation creates resilience: a new or temporary member of staff can understand how the finance function works and operate it effectively without extended handover time. It also creates the foundation for improvement — you cannot systematically improve a process that is not documented.

A fractional FD produces clear, practical process documentation as part of the review engagement — not dense policy documents, but working-level procedures that describe exactly how each finance process should be performed, by whom, with what authorisation, using which system, and with what output. For businesses approaching an audit or preparing for due diligence, this documentation is particularly valuable.
