How Much Does Outsourcing Accounting Services Cost for Practices in the UK?

The outsourcing accounting services cost for accounting practices based in the UK can range from approximately £8 to £50 per hour or £150 to £1,000+ per month, depending on the engagement model.

But the real cost is not the price of outsourcing accounting services; it’s about profitability, scalability, efficiency, and whether your practice can grow without overloading your accounting team.

Right now, accounting practices are facing increasing client demands, more compliance requirements, and staff shortages. Hiring out additional accountants is not an option because it is increasingly expensive and difficult.

According to the Deloitte Global Outsourcing Survey 2024, 80% of executives are planning to maintain or increase investment in third-party outsourcing. That’s why outsourcing is being preferred by many accounting practices as a strategic growth model in 2026.

But outsourcing is not a one-size-fits-all solution. To get a deeper understanding, we have prepared this guide.

What Factors Affect the Cost of Outsourcing Accounting Services?

The outsourcing accounting services cost is influenced by multiple factors, and we have listed some of the important ones that need your attention.

Scope of Services

The more accounting functions you want to outsource, the higher the outsourcing accounting services cost.

For example:

• Bookkeeping only → lower cost
• Bookkeeping + payroll + VAT + reporting → higher cost

Many practices prefer to outsource only repetitive tasks because they are time-consuming and resource-intensive, while some prefer to outsource complex accounting tasks because of the risk of errors involved.

Transaction Volume

If your practice processes 200 invoices per month, it will certainly cost you less than one that processes 5,000 invoices per month. Large transaction volumes mean more staff, automation and review processes to be dedicated by your outsourcing partner.

Complexity of Client Work

Handling simple bookkeeping tasks is easier than handling:

• Multi-entity accounting
• Ecommerce reconciliation
• International VAT
• Construction industry schemes
• Recruitment payroll

Complex workflows require experienced professionals and additional quality checks.

Turnaround Expectations

Quick turnarounds mean dedication of more capacity, which will lead to an increase in outsourcing accounting services cost.

For example:

• Same-day bookkeeping updates
• Rapid month-end closing
• High-frequency reporting

Technology Integration

Prefer to choose an outsourcing partner that offers its accounting outsourcing services using the best accounting software and other tools, such as:

• Xero
• QuickBooks
• Sage
• Dext
• Hubdoc

Firms with disconnected systems or manual processes usually experience higher operational costs.

Level of Expertise Required

For doing bookkeeping support, you will need less experienced outsourcing services, which will cost you less. On the other hand, specialised advisory services or those of a senior accountant will cost you more.

Services involving:

• Management reporting
• Forecasting
• Compliance reviews
• Audit preparation

typically require more experienced professionals.

Outsourcing vs In-House Accounting: Cost Comparison for Practices

Many accounting practices make the mistake of comparing outsourcing accounting services cost only with their employee salaries. Instead, you will have to widen your comparison.

In-House Hiring Costs

Hiring internally includes expenses such as:

• Salaries
• Employer NIC contributions
• Pension costs
• Recruitment fees
• Software licenses
• Office equipment
• Training costs
• Sick leave and holidays

Outsourcing Costs

With outsourcing, you will typically pay only for:

• Work completed
• Required capacity
• Agreed service scope

Cost Comparison Table: In-House vs Outsourced Accounting Support

Cost Area	In-House Accounting Team	Outsourced Accounting Support
Salary Costs	Fixed annual salaries	Flexible monthly/service-based fees
Employer NIC & Pension	Additional employer expense	Usually included in outsourcing fee
Recruitment Costs	High recruitment and onboarding costs	No recruitment expense
Training & Development	Ongoing investment required	Managed by outsourcing provider
Office Space & Equipment	Additional desks, systems, hardware	No additional office overhead
Software Licenses	Separate user licenses required	Often included/shared through provider
Staff Absences	Productivity affected by holidays or sick leave	Backup resources typically available
Scalability	Hiring needed for growth	Easily scale support up or down
Seasonal Workloads	Overtime or temporary staff needed	Flexible support during busy periods
Turnaround Time	Depends on internal capacity	Dedicated teams improve efficiency
Operational Risk	Staff turnover impacts workflow	Reduced dependency on single employees
Typical Annual Cost	£50,000–£70,000+ per employee	Often significantly lower depending on scope

Common Pricing Models in Accounting Outsourcing

The UK accounting market is filled with multiple outsourcing providers that use different pricing models to handle different service types and workflow complexities.

Fixed Monthly Pricing

A predictable monthly fee based on the agreed service scope.

This pricing model follows a predictable monthly fee structure based on an agreement between the service provider and the accounting practice.

The model is ideal for:

• Stable workloads
• Recurring bookkeeping
• Long-term support arrangements

Pay-As-You-Go Pricing

Under this Pay-As-You-Go model, the charges will be based on the actual work done or hours spent on the work.

Ideal for:

• Expanding practices
• Seasonal workloads
• Firms needing flexibility

This model is highly popular among practices because it avoids paying for services they don’t want.

Per-Transaction Pricing

Charges will be based on:

• Number of invoices
• Payroll runs
• Reconciliations
• Client accounts managed

This model is ideal for:

• High-volume transactional work

Dedicated Resource Model

There are service providers that dedicate an entire team to work exclusively for a practice.

Such a model serves better for:

• Practices with large, ongoing workloads or outsource entire accounting tasks
• Practices needing consistent operational support

Hidden Costs Accounting Practices Should Be Aware Of

It is accurate that outsourcing reduces a considerable amount of operational costs, but there are potholes in the form of hidden expenses that can ruin your experience if not taken into account.

Poor Transition Planning

When the transition of accounting tasks from your accounting team to your outsourcing partner is badly managed, then it creates issues like:

• Duplicate work
• Operational delays
• Inconsistent reporting
• Client disruption

This is why structured onboarding is critical.

Inconsistent Communication

Some unprofessional service providers will lack proper communication mechanisms, leading to:

• Missed deadlines
• Unclear reporting
• Quality concerns

The lowest bidder provider is not always the most cost-effective long-term option.

Lack of Standardised Workflows

Without proper procedures in place, you will find yourself spending additional time just reviewing the outsourced work internally. This defeats the entire purpose of outsourcing, time saving and reduction of workload.

Technology Gaps

Some providers might still use outdated systems, which will create integration challenges with your latest accounting systems. Therefore, place emphasis on technology integration while choosing your outsourcing partner.

Is Outsourcing Accounting Services Worth the Cost for UK Practices?

Outsourcing is worth a shot because of the wide-ranging benefits it puts on the table. It has enabled multiple practices to reduce their workload and provide insights to make better decisions.

Saving Time

Managing accounting tasks take time and outsourcing saves that time by taking over the task. This enables you to focus on other important aspects like advisory services or strategic planning.

Saving Costs

Outsourcing prevents you from spending on:

• Salaries
• Employer NI
• Pension contributions
• Training costs
• Software fees
• Recruitment

For many accounting practices, outsourcing costs less than hiring even one junior bookkeeper.

Access to Experts

Through a professional outsourcing provider, you will get access to experts, such as:

• Bookkeepers
• Payroll specialists
• Tax experts
• VAT advisers
• Finance managers

Instead of recruiting multiple staff, you will have access to trained professionals without incurring hiring costs.

Improving Operational Efficiency

Your outsourcing partner will keep your clients’ books in order and in compliance.

Based on that, you will receive:

• Clean records
• Clear reports
• Better cash flow tracking
• Accurate invoices and payments

These clean records and reports can provide insights to your clients during their decision-making process.

Accuracy and Compliance

Professional accountants of service will ensure that:

• VAT is filed correctly
• Payroll follows HMRC rules
• Deadlines are met
• Year-end accounts are accurate
• Tax savings are not missed

This reduces errors and helps avoid penalties.

Tax Efficiency and Savings

Good outsourcing providers will try to save taxes for your clients through tax efficiency by:

• Claiming all allowable expenses for your clients
• Using the correct VAT scheme
• Improving cash flow
• Planning taxes in advance
• Reducing your overall tax liability legally

These savings often cover the cost of outsourcing.

Better Financial Insight

Outsourcing provides access to monthly or weekly reports that help you understand:

• Profit
• Cash flow
• Costs
• Sales trends
• Budget performance

This gives you insights into your client’s performance and allows you to guide them towards clearer decision-making.

Peace of Mind

Knowing that trained professionals are handling your clients’ accounts reduces stress.

You do not have to worry about:

• Missed deadlines
• Incorrect VAT
• Late payroll
• Tax errors
• Missing receipts

When Should Accounting Practices Consider Outsourcing?

Many practices wait until the end when it comes to outsourcing, but this must be prevented at all costs. Therefore, look at the common signs which will indicate to you that it’s time to outsource. These signs are.

• Staff burnout
• Missed deadlines
• Rising client complaints
• Recruitment struggles
• Month-end backlogs
• Inconsistent quality
• Inability to scale profitably

If your team is spending more time on error corrections and managing operational pressure due to expansion, then it’s time to outsource
