How much can my business save by having our payroll processed by an external partner?

The savings you derive from  outsourcing your payroll function will depend on how many employees you have. Many full service payroll service providers will charge a few pounds per pay slip, which makes this a relatively inexpensive option as long as your payroll is small. On the other hand if you have hundreds of employees this type of fee structure will be quite costly. You should bear in mind however that using internal staff to process pay slips can also be pretty expensive (in terms of salary, health insurance and other benefits). Why not seek out price quotes from outsourced payroll specialists? If you provide them with the actual numbers involved at your business they can give you a relatively precise quote as to how much you should expect to pay.
