Key takeaways

FreeAgent, Xero, QuickBooks, and Sage are the four most widely used accounting packages among UK contractors operating through limited companies.
All four platforms support Making Tax Digital for VAT, but only FreeAgent includes built-in IR35 status indicators as standard.
Monthly costs range from around 12 to 40 pounds depending on the plan, with most contractors choosing a mid-tier package that covers invoicing, expenses, and bank feeds.
Most contractor accountants have a preferred platform and can offer discounted licences, so check with your accountant before purchasing separately.
Cloud-based software with bank-feed integration reduces manual data entry and gives both you and your accountant real-time visibility of your company finances.

Software can go a long way in assisting businesses and accountants alike. Often an accountant will have a preferred software that they use which could be something bespoke they have developed themselves or something they love and trust off of the shelves.

Our accountants at Forma have tried and tested many different solutions with FreeAgent being the clear winner in the contractor accounting tool.

Frequently asked questions

Which accounting software do most UK contractor accountants recommend?

FreeAgent and Xero are the two most commonly recommended platforms by UK contractor accountants. FreeAgent is popular for its simplicity, built-in tax calculators, and automatic corporation tax estimates. Xero is favoured for its extensive app marketplace and multi-currency support. Your accountant may already have a preferred platform and could offer a discounted licence as part of their monthly package.

Do I need accounting software if I already have an accountant?

Yes. Accounting software gives you real-time visibility of income, expenses, and tax liabilities between accountant check-ins throughout the year. It also automates bank feeds, receipt capture, and VAT calculations, significantly reducing the manual work your accountant needs to do at each reporting period and often lowering their monthly fees as a result.

Is FreeAgent or Xero better for a contractor limited company?

FreeAgent is generally simpler and includes corporation tax estimates, dividend tracking, and IR35 tools out of the box without needing any add-ons. Xero offers a larger third-party app ecosystem and stronger multi-currency invoicing capabilities. If you trade internationally or need advanced integrations with other business tools, Xero is likely the better choice for your company.

How much does contractor accounting software cost per month?

Expect to pay between 12 and 40 pounds per month depending on the provider and plan tier you select. FreeAgent starts around 15 pounds per month, Xero from 17 pounds, and QuickBooks from 12 pounds. Some contractor accountants bundle software access into their monthly accounting fee at no additional cost to you.

Does contractor accounting software handle Making Tax Digital?

All major platforms including FreeAgent, Xero, QuickBooks, and Sage are HMRC-recognised for Making Tax Digital for VAT. They allow you to file quarterly VAT returns directly from the software, maintain the required digital records, and keep a complete audit trail without needing any additional tools or manual submission through the HMRC portal.

Can I switch accounting software mid-year without losing data?

Yes. Most platforms offer data import tools and your accountant can help migrate opening balances and historical transactions. The best time to switch is at the start of a new financial year, but a mid-year move is entirely possible with a clean trial balance and completed bank reconciliation at the changeover date. Allow two to three weeks for the transition.

What features should a contractor look for in accounting software?

Prioritise automated bank feeds, MTD-compliant VAT filing, expense receipt scanning, professional invoicing, and direct accountant access as your essential core requirements when evaluating platforms. Useful extras include corporation tax estimates, dividend tracking, mileage logging, and seamless integration with payroll software if you run a salary and dividend payment strategy through your limited company.
