Outsourced Bookkeeping: What It Is, and How It’s Priced
Outsourced bookkeeping is essentially the decision to hire someone outside your company to handle the day-to-day financial record-keeping duties. That can be things like sorting out your bank accounts, dealing with invoices, keeping your ledgers up to date and getting your tax records in order. In the UK for instance, there’s generally 3 different pricing models you’ll come across: paying by the hour, having a fixed monthly deal or shelling out an annual fee
For accounting firms, outsourcing is usually done on a ‘partner with us and pretend we’re you’ kind of basis. Your outsourcing partner will be working away behind the scenes using your systems, and as far as your clients are concerned, nothing much will have changed. The only differences they’ll notice are that the work is getting done somewhere else and is now a variable expense (a fee that goes up and down with the amount of work done) rather than a fixed salary for an employee.
Which engagement models do bookkeeping outsourcing providers offer?
UK outsourcing providers offer three main engagement models: the full-time employee model, the onshoring model, and the dedicated personal model. Each is priced differently, and the model you choose usually has a larger effect on your total cost than the hourly rate does.
Every accounting practice has its unique accounting requirements for this reason bookkeeping outsourcing service provider offer customised pricing that will meet their exact requirements. However, certain models are highly preferred by your competitors, these models are:
Full-time Employee Model
Under this model, an outsourcing service provider will provide a dedicated employee to you at a fixed price.
Onshoring Model
Some practices prefer to meet the outsourcing representative onshore to resolve queries or for a quick discussion. To address this demand, many outsourcing service providers are offering onshore support.
Dedicated Personal Model
Under it, the outsourcing service provider will assign a dedicated accountant who will only work for you and will provide all the required technical and admin support. In this model, you will also get specialised services to handle complex accounting matters which will help you in scaling up your accounting practice.

What is the cost of hiring a bookkeeper?
Hiring a bookkeeper involves more than just covering day-to-day bookkeeping tasks. Accounting practices also need to account for recruitment time, onboarding, training, software access, compliance responsibilities, and ongoing supervision. During quieter periods, in-house resources may be underutilised, while growing transaction volumes can quickly stretch internal capacity.
Because these internal demands increase as businesses scale, many UK accounting firms assess whether hiring remains sustainable in the long term. This is where outsourced bookkeeping becomes a practical alternative — offering skilled support, flexibility, and controlled overheads without the commitment and operational burden that comes with expanding an in-house team.
| Cost component | In-house bookkeeper | Outsourced |
| Gross salary or fee | Fixed, paid year-round | Variable, paid per hour or package |
| Employer National Insurance | 15% above £5,000 (2026/27) | Not applicable |
| Workplace pension | Minimum 3% employer contribution | Not applicable |
| Recruitment and onboarding | Agency fees plus manager time | Included in provider onboarding |
| Software licences | Paid by the practice | Usually provider-side or shared |
| Holiday, sickness and cover | Practice absorbs the gap | Provider maintains continuity |
| Quiet-period capacity | Paid regardless of workload | Scaled down |
What are the cost benchmarks for outsourced bookkeeping per hour, per month or per year?
Multiple factors influence the cost of bookkeeping outsourcing but none influence it more than the pricing models adopted by outsourcing service providers. These price models are as follows:
What are cost benchmarks for outsourced bookkeeping per transaction or per hour?
The three published benchmarks are roughly £13.33 per hour, £200 to £600 per month, and £1,200 to £5,000 per year. Which one applies depends on whether you buy time, capacity, or a full annual service.
- Hourly Rates: Currently, the average cost of a bookkeeper’s service will be £13.33 per hour (subject to change). However, this will increase if the bookkeeper possesses specialised skills.
- Monthly Fees: Small-sized accounting practices are offered monthly package by service providers. Such a package may will cost between £200 to £600 per month (subject to change).
- Yearly Fees: Many would prefer only to pay for yearly bookkeeping services. The cost for annual bookkeeping services could range between £1,200 to £5,000 or more but that could change based on your requirements.
Which factors influence outsource bookkeeping services cost?
Five factors set the price: the size of your client’s business, the services required, the experience and qualifications of the bookkeeper, the provider’s location, and how frequently you need the service. Transaction volume is the single largest driver.
It must be noted first that every outsourcing service provider has its own bookkeeping charges. Plus, many other factors will affect the bookkeeping charges you will pay. Many of these factors also affect the overall accounting outsourcing cost but more on that latter. We are going to focus on some of those important factors that impact outsource bookkeeping services cost first.
Size of Your Client’s Business
One of the major factors that influence bookkeeping charges is the size of your client’s business. The larger the business size of your clients more will be its transactions. Also, there will be a considerable number of complex transactions that will require expertise and time, leading to added costs. For example, if your client is a small sole trader then there will be a smaller number of monthly transactions which will require only a few hours of bookkeeping support. However, if your client is a medium-sized business then it will have hundreds or thousands of transactions which will lead to a lot of work for your outsourcing partner and more costs.
Services Required
The services you require from your bookkeeping service provider will also influence the cost. If you require only basic bookkeeping services such as banking reconciliations and data entry then the outsource bookkeeping services cost will be minimal. But if you require advanced bookkeeping services along with payroll and VAT then expect the cost to go up.
Experience and Qualification of the Bookkeeper
A bookkeeper’s experience and qualifications matter when outsourcing your bookkeeping task to a service provider. The higher the experience or certification of the bookkeeper more will be its service charge. An experienced bookkeeper comes with multiple professional certifications from the Institute of Certified Bookkeepers (ICB) or the Association of Accounting Technicians (AAT) and professional bookkeeping service providers like Corient hire such bookkeepers. Only those who are willing to shell out more money can get access to their expertise and experience. For further research we would advise you to study the case studies and website of service providers and compare them, it will give you a clear picture of their experience and qualifications of their staff.
Location
Location matters when it comes to determining the bookkeeping rates. If the outsourcing service provider is located in London and hires bookkeepers only from London then your bookkeeping charges will be high. On the other hand, those service providers based in semi-urban or rural areas and recruiting from those areas will charge less for bookkeeping services. This price difference is due to the cost of living which is higher in expensive cities like London.
Service Frequency
Whether you need bookkeeping services from a service provider daily or only on certain occasions will affect the bookkeeping cost. Some of your clients will need bookkeeping services on a daily, monthly, or yearly basis, while some will require them only on some occasions like tax seasons. Outsourcing bookkeeping service providers will offer various pricing models and based on the service demand frequency the per-hour rates will be decided. More the frequency of bookkeeping service less will be the hourly rates.
