How Much Does Accounting & Invoicing Software Cost? A UK Small Business Pricing Guide
What You Can Expect to Pay for Accounting Software in the UK
For most UK small businesses, accounting and invoicing software costs anywhere between £0 and £120 per month, depending on the features you need and the size of your operation. The good news is that even entry-level paid plans now include essentials like bank feeds, VAT returns, and invoicing.
Pricing structures vary widely — some tools charge per user, others per feature tier. Understanding what drives the cost will help you avoid overpaying for tools you simply do not need.
Free vs Paid: Is Free Software Enough?
If you primarily need point-of-sale and basic invoicing, a free tool like Square POS is a genuinely capable starting point. It includes integrated card payments with transparent UK transaction fees, and you can be up and running the same day with no monthly subscription.
However, free tools rarely cover Making Tax Digital (MTD) compliance, VAT submissions, or detailed profit and loss reporting — all of which become critical as your business grows or once you are VAT-registered. For most small businesses trading beyond the hobby stage, a paid plan is the more practical long-term choice.
The Main Pricing Tiers Explained
- £0/month — Basic invoicing and POS tools (e.g. Square). Suitable for very early-stage businesses or sole traders with simple needs.
- £15–£20/month — Core accounting platforms with MTD compliance, bank feeds, and VAT filing. The sweet spot for most small UK businesses.
- £49–£119/month — Field service management platforms that include invoicing alongside job scheduling, quoting, and mobile team tools.
The jump from the mid-tier to the higher tier is largely about industry-specific functionality rather than accounting depth. If you run a trade or service business with mobile engineers or field workers, that premium often pays for itself quickly.
Recommended Software by Budget
Xero — £15/month
Xero is one of the most widely used accounting platforms among UK small businesses, and for good reason. It is fully MTD-compliant for VAT submissions, connects seamlessly with UK banks, and offers an intuitive interface that does not require an accounting background to navigate. At £15/month on the entry plan, it represents excellent value for limited companies, partnerships, and growing sole traders alike.
FreeAgent — £19/month
FreeAgent is particularly well-suited to UK sole traders and freelancers, with strong integrations across major UK banks including NatWest and Royal Bank of Scotland. It is fully HMRC Making Tax Digital compliant and handles Self Assessment, VAT, and payroll within a single dashboard. At £19/month, it is a compelling all-in-one option if you are a one-person operation wanting to stay on top of your tax obligations without an accountant doing the heavy lifting.
Sage Accounting — £15/month
Sage Accounting is a trusted name in UK business software and one of the most established MTD-compliant platforms available. It offers excellent UK bank integrations and is particularly well-regarded by businesses in sectors like trades and hospitality. Starting at £15/month, Sage is a solid choice if you want a familiar, reliable brand with strong local support.
Jobber — £49/month
Jobber is aimed squarely at field service businesses — think landscapers, cleaners, and electricians — and bundles invoicing into a broader job management platform. At £49/month, you also get quoting, scheduling, and polished mobile apps that keep field teams connected. It is not a pure accounting tool, so you would typically pair it with Xero or FreeAgent for full financial reporting.
Commusoft — £119/month
Commusoft sits at the premium end, tailored specifically for UK trades businesses such as plumbers, gas engineers, and heating installers. It includes robust job scheduling, mobile access, and invoicing built around the workflow of a busy trades company. At £119/month, it is a significant investment, but one that makes sense for established trade businesses processing high volumes of jobs each month.
Key Factors That Affect Your Total Cost
- MTD compliance — Essential if you are VAT-registered or preparing for Making Tax Digital for Income Tax (MTD for ITSA).
- Number of users — Many platforms charge extra for additional team members beyond the base plan.
- Payment processing — Tools like Square, Zettle, and SumUp charge per transaction rather than a monthly fee, which suits lower-volume sellers.
- Add-ons — Payroll, advanced reporting, and multi-currency support often cost extra on entry-level plans.
- GDPR considerations — Ensure any platform you choose stores data within the UK or EEA and offers a compliant data processing agreement.
What Most UK Small Businesses Should Budget
For a typical UK sole trader or small limited company, a budget of £15–£20 per month for a core accounting platform covers the vast majority of day-to-day needs. If you operate in a trade or field service industry, budgeting up to £50–£120 per month for a specialist platform can save considerable administrative time.
Start by confirming whether you need MTD compliance now or in the near future — that single requirement will immediately narrow your shortlist to the right tools and help you avoid the false economy of under-specifying your software.
