The cost of a payroll system for a small business depends on the size of your team and the features you need. Most systems charge a monthly fee and may increase slightly as your business grows. Many small business owners choose to have their accountant manage payroll, which can work out more efficient and cost-effective in the long run.
The best payroll service is one that saves you time, keeps you compliant with HMRC, and fits your business size. Some prefer cloud software they can manage themselves, while others find it easier to outsource payroll to an accountant. If you value peace of mind and flexibility, working with someone who understands your business can make all the difference.
Absolutely. An accountant can help you stay on top of tax deadlines, keep your finances organised, and offer advice to help your business grow. Many small business owners find they save time, reduce stress, and often save money too. Whether you’re just starting out or already growing, having someone in your corner is a real benefit.
Payroll costs vary depending on whether you do it yourself or get support. Many business owners use Xero with help from their accountant, which can be both affordable and efficient. The real value is in saving time and avoiding costly mistakes, especially when managing pensions and HMRC submissions.
Gusto and QuickBooks offer different payroll features, but it really comes down to what suits your workflow. For many small businesses, Xero is the better fit — especially if your accountant works within it. It keeps payroll, bookkeeping, and compliance all under one roof, which can be more efficient overall.
QuickBooks payroll pricing depends on the package and number of employees. That said, many small businesses prefer Xero because it combines payroll and accounting in one place. It works smoothly when managed by your accountant, helping you stay compliant without the usual back and forth.
