Finance and accounting (F&A) interim support provides temporary capacity to help finance functions fill urgent needs for personnel. Most often, these requirements are only for a short term. Interim support adds skilled F&A specialists to your existing team on a very short notice, for a defined period or as ongoing capacity, without carrying them as domestic full-time employees. This simple and straightforward consulting engagement model ensures that complete control over the finance function rests with you – the CFO, Controller or accounting managers at the company.Â
Interim staff are highly qualified and experienced professionals, who can directly integrate into your team, work in your ERP, follow your close calendar, adhere to your KPIs, and stay in the same escalation path as everyone else in your team. Â
One of the larger benefits of interim finance and accounting support is that it enables improved capacity planning, especially for rapidly growing businesses whose finance functions are struggling to keep up with expansion across product/service lines, geographies and entities. CFOs are able to proactively decide what finance work stays in-house, what gets sourced, and how that mix should evolve as the business grows. In this blog, we delve deeper into why F&A interim support is suitable for businesses in the UK and how they can choose suitable solutions.Â
What are the capacity challenges facing finance teams in the UK?
Finance and accounting talent is in demand in the UK. In a recent survey, 40% UK CFOs stated that lack of diversity of experience within finance teams in areas such as data is responsible for finance seen as either an enablement function supporting day-to-day operations and transactions, or as a stewardship and control function, within their organization. Â
In another Q2 2026 survey of UK finance leaders, ‘wider business impetus for cost control’ was said to be a key factor behind reduced hiring of graduates. AI and outsourcing play a major role in reducing the need for permanent hires in companies. Â
For CFOs, talent shortages are a critical concern. It could potentially derail strategic decision-making, capital allocation, hiring and expansion, and agility. Â
What is interim finance support?
Interim finance support is the temporary engagement of finance and accounting professionals who bring hands-on expertise and leadership for a definite period, without long-term permanent salary overheads. At DBSL, we provide experienced, qualified and business-ready professionals who can fit into your ERP and processes and start delivering from day one. From our experience, this is highly helpful for organizations during a transition, crisis, restructuring, or specific project.Â
As businesses mature and challenges become more sophisticated, most finance leaders identify a need to deliver faster insights, tighter controls, and better visibility. However, this cannot come with a complimenting increase in fixed costs and hiring time to build a capable team. This is where interim finance support plays a crucial role. Â
Interim support is full-time resources, deployed temporarily, that fully embed into client ERPs and workflows, work on their systems and software, follow client specified SLAs and KPIs, and are placed in the same escalation path as internal finance team members. There is no distinguishable difference between internal resources and interim support other than that the payroll, recruitment, onboarding, HR, and IT of the temporary staff rests with the provider. When you partner with globally trusted flexible resourcing providers, they ensure the temporary staff work from secure, SOC 2-compliant sites.Â
What roles are suitable for interim finance support?
Interim support in finance and accounting is accessible across function and seniority levels.Â
The range of roles available through interim finance support is wider than most finance leaders realize. Most think of interim finance as covering a gap at the top – an interim CFO or Finance Director while a permanent hire is recruited. In practice, the roles most commonly engaged on an interim basis sit in the middle of the finance function, where specialist skills like group consolidation, revenue recognition, or AP automation are needed for a defined period without justifying a permanent hire. Â
Interim management roles like CFOs and Finance Directors are typically engaged during leadership transitions, pre-IPO preparation, or periods of significant financial restructuring.Â
Financial Planning and Analysis (FP&A) fills the planning and analytical capability gap during restructuring or rapid growth phases.Â
Other roles that are favoured by UK CFOs in the flexible resourcing model include:Â
- Management Accountant – monthly close, management accounts preparation, and variance commentaryÂ
- Group Consolidation Accountant – multi-entity consolidation, intercompany elimination, and group reportingÂ
- AP Specialist / Accounts Payable Clerk – invoice processing, three-way matching, and supplier query managementÂ
- P2P Process Improvement Specialist – project-based engagement for AP automation or ERP implementation supportÂ
- Cash Application Specialist – payment matching, remittance processing, and unallocated cash managementÂ
- Billing Specialist – invoice generation, billing dispute resolution, and customer account managementÂ
- Interim Tax Manager – corporate tax compliance, VAT returns, and tax provision preparationÂ
- VAT Specialist – multi-jurisdiction VAT compliance, particularly for European cross-border businessesÂ
- Transfer Pricing Analyst – intercompany pricing documentation and complianceÂ
- Cash Flow Forecasting Specialist – short-term liquidity forecasting and working capital analysisÂ
- Internal Audit Analyst – risk assessment, control testing, and audit report preparationÂ
- Audit Support Specialist – audit preparation, workpaper organization, and auditor query managementÂ
- Finance Process Improvement Specialist – process mapping, SOP documentation, and workflow redesignÂ
- Finance Automation Analyst – RPA deployment, workflow automation, and intelligent document processingÂ
Benefits of interim finance support
The UK finance talent market remains one of the tightest in Europe. Competition for qualified finance professionals is intense, salary expectations have risen significantly, and the average time to fill a senior finance role has stretched to three months or more in most markets. For CFOs managing a finance function that needs to perform regardless of what is happening in the recruitment market, interim finance support has become a practical and increasingly common solution.Â
Interim finance and accounting professionals contribute from day one without the onboarding curve of a permanent hire, and they leave without the cost and disruption of redundancy when the requirement ends.Â
Key benefits for UK CFOs:Â
- Speed of deployment – experienced interim professionals can typically be in place within two to four weeks, significantly faster than the three to six month timeline for permanent hiringÂ
- No long-term overhead – interim support adds capacity without adding permanent headcount, keeping the cost structure flexible in an uncertain economic environmentÂ
- Specialist skills on demand – access capabilities like group consolidation, transfer pricing, IFRS transition, or ERP implementation finance that most mid-market teams do not maintain permanently in-houseÂ
- Business continuity – cover unexpected departures, parental leave, or sickness absence without disrupting the close cycle, audit preparation, or board reporting scheduleÂ
- IR35 compliance managed – a reputable interim finance provider handles the employment, compliance, and IR35 assessment obligations, removing a significant administrative burden from the client organizationÂ
- Immediate contribution – interim professionals are experienced enough to understand a new environment quickly and deliver without the extended ramp-up period that junior permanent hires requireÂ
- Flexibility to scale – extend, reduce, or end the engagement as requirements change without the employment law obligations that govern permanent headcount decisionsÂ
How to choose a partner?
Choose an interim finance support partner based on capability, speed, governance, and flexibility, not simply availability. The best partner for a financial close project may not be the best partner for FP&A or transformation support. Filling in for temporary leave coverage is different from providing qualified talent for specialized capability gaps. It is important that you choose a partner that solves the problem you are facing, while fitting into your finance function with minimal disruption.Â
You must verify ISO 27001 certification, SOC certifications where relevant, and GDPR compliance where applicable.Â
The best partners do more than fill vacancies. They help finance leaders bridge capacity gaps, execute transformation initiatives, and determine whether the challenge requires temporary support or a more fundamental operating model change. Â

Conclusion
Interim finance professionals bring specialist expertise that many permanent teams do not carry in-house – whether that is group consolidation experience for a year-end audit, IFRS 15 revenue recognition capability for a new contract structure, or FP&A modelling depth for a fundraising process. They are available just for the required time, and do not result in long-term, fixed overhead for companies. Ultimately, it is easy to see that the benefits go far beyond covering a vacancy.Â
