For many accounting firms, growth is no longer limited by demand. It is limited by capacity.
In 2026, firms continue to face a challenging combination of talent shortages, rising employment costs, increasing compliance requirements, and growing client expectations. As a result, outsourcing has evolved from a cost-saving tactic into a strategic way to access skilled talent, create capacity, and support sustainable growth.
One of the most common questions firms ask, however, is:
“How much does it cost to outsource accounting services?”
The cost of outsourcing accounting services typically ranges from £1,500 to £3,000 per month under a dedicated Full-Time Employee (FTE) model, depending on the experience and seniority of the resource.
However, understanding accounting outsourcing cost requires looking beyond the monthly fee. Pricing can vary based on factors such as the scope of work, level of expertise required, engagement model, and support structure provided by the outsourcing partner.
In this guide, we’ll break down the most common accounting outsourcing pricing models, explain the factors that influence costs, and compare the true cost of hiring in-house versus accounting outsourcing services in 2026.
The cost of outsourcing accounting services varies approximately between £1,500 to £3,000 per month for the FTE Model based on the seniority and expertise of the resource.
What does £1,500-£3,000 per month typically include?
This helps justify the price before readers reach the comparison table.
In order to understand how accounting outsourcing companies price their services, it is important to comprehend the important factors and engagement models that determine the real cost of the outsourcing association.
The real outsourcing accounting cost UK can vary depending on several factors.
An experienced accountant or manager will generally command a higher monthly fee than a junior resource. Firms often choose resources based on the complexity of work and level of client interaction required.
The broader the scope of work, the greater the investment. Firms may choose support for bookkeeping and compliance tasks alone or extend outsourcing to accounts preparation, tax, payroll, management reporting, and advisory support.
Pricing differs based on whether a firm requires a dedicated full-time resource, onshore support, or a more comprehensive practice outsourcing solution that includes additional management and technical support.
The systems and workflows used by a firm can influence onboarding requirements and the level of specialist expertise needed. Experience with specific accounting software, tax platforms, and practice management solutions may impact pricing.
Some firms need support only during peak periods such as self-assessment season or year-end accounts preparation, while others require dedicated year-round capacity. The level and duration of support can influence overall costs.
Basic bookkeeping work requires a different skill set from management accounts, tax planning, audit support, or advisory work. More specialised work typically requires more experienced resources.
An engagement model is a strategic set of guidelines that define the association between an outsourcing provider and its client. It determines the roles and responsibilities of each firm, their obligations and commitments, and the duration of the association.
These regulations and terms and conditions are systematically written down in an outsourcing contract, which both parties sign.
Each accountancy practice has diverse outsourcing requirements. Top accounting outsourcing companies, therefore, provide custom pricing to clients based on their exact needs.
However, there are certain engagement models for UK accounting outsourcing that accountancy firms widely prefer. Let’s look at some of them.
In this blog, we will cover the following engagement models that QXAS offers:
The Managed Full-time Employee (MFTE) model is a proven, most effective engagement model for accountancy outsourcing.
In this model, as the name suggests, the outsourcing company provides a dedicated employee and a dedicated manager or team leader to a practice at a fixed fee per month.
The outsourced accounting services pricing for the FTE model ranges approximately from £1,500/month to £2,000/month for an accountant/ senior accountant, based on the experience of the resource.
For a more senior resource such as a manager, the pricing approximates from £2,500/month to £3,000/month.
The fixed amount is billed to the accounting practice at the end of each month. Under this model, the outsourcing company scopes the number of hours to be completed within the monthly fee.
Outsourcing is mostly about offshoring. However, some practices prefer having an onshore manager for quick discussions, meetings, and resolution of queries.
To cater to this requirement, many leading accounting outsourcing companies like QXAS offer the onshore support model.
The pricing for the onshore support model depends on accountancy firms’ particular requirements and can be deduced by requesting an outsourcing firm for a custom pricing quote.
The Practice Outsourcing Solution is a more comprehensive model blending offshoring and onshoring to deliver a seamless outsourcing experience.
In this model, the outsourcing company provides a dedicated individual working exclusively on your project along with complete client, admin, and technical support.
In addition, you get specialized assistance on intricate accounting matters that can help you scale your practice effectively.
Here’s a quick summary of all the engagement models.

Although expanding an in-house team is often viewed as a natural step for growing accounting firms, the true cost of hiring in 2026 extends far beyond salary alone.
