Wondering about the average cost for payroll services? Discover the impact of employee numbers, payment intervals, and more on your business' payroll costs.
Factors Affecting Payroll Service Costs
Several factors influence the cost of payroll services, including the number of employees, payment frequency, and the level of automation required. Businesses with larger workforces often pay more, as do those requiring weekly rather than monthly payroll processing.
Additional features such as tax filing, direct deposits, and compliance management can also increase costs. The choice between in-house payroll software and outsourced payroll providers plays a significant role in pricing, with outsourced services typically costing more but offering greater convenience.
Industry-specific requirements, such as managing contractor payments or handling pensions, can further impact pricing. Understanding these factors helps businesses select the most cost-effective payroll solution suited to their needs.
Different Types of Payroll Services
Payroll services range from basic software solutions to full-service providers. Basic payroll software enables businesses to manage payroll in-house, handling employee wages, tax deductions, and payslips. More advanced software includes tax compliance and integration with accounting systems.

Outsourced payroll providers take care of the entire process, from salary calculations to tax submissions, reducing administrative work. Some businesses opt for hybrid solutions, using software for routine payroll and outsourcing tax filing and compliance tasks.
Cloud-based payroll services offer flexibility and automation, allowing remote access and integration with HR management systems. The choice depends on budget, company size, and the complexity of payroll needs.
Average Costs for Small Businesses
Small businesses with fewer than 50 employees typically pay between £20 and £100 per month for basic payroll software. Outsourced payroll providers charge around £5 to £10 per employee per month, with additional fees for tax filings, pensions, and compliance services. Some providers offer flat monthly fees, ranging from £50 to £200, depending on features included.
One-off setup costs may apply, particularly for businesses transitioning from manual payroll systems. Small businesses can minimise expenses by choosing software with essential features or outsourcing payroll only for tax submissions. Comparing providers and selecting scalable options helps control costs while ensuring accurate payroll management.
Costs for Medium and Large Businesses
Medium and large businesses typically require more advanced payroll solutions due to greater workforce size and compliance needs. Payroll software for businesses with 50 to 250 employees costs between £100 and £500 per month.

Outsourced payroll services charge around £8 to £15 per employee, with additional costs for tax filing, pensions, and reporting. Large businesses with over 250 employees may pay over £1,000 monthly for full-service payroll providers.
Costs vary depending on payment frequency, the number of locations, and integration with HR and accounting systems. Investing in a comprehensive payroll solution ensures compliance, accuracy, and efficiency at scale.
Comparing In-House and Outsourced Payroll Costs
Managing payroll in-house typically involves software costs, staff salaries, and time spent on administration. Payroll software subscriptions range from £20 to £500 per month, while hiring payroll professionals adds significant expenses. Outsourcing payroll removes administrative burdens, with fees based on employee numbers and service levels.
While in-house payroll can be cost-effective for smaller businesses, outsourcing ensures compliance and reduces errors. Larger businesses often find outsourcing more efficient due to the complexity of tax laws and payroll regulations. Comparing costs involves assessing software expenses, staff time, and risk factors associated with errors or non-compliance.
