Construction businesses carry accounting demands that trip up general purpose software: the Construction Industry Scheme with its deductions and verifications, subcontractor payments, retentions, and the need to cost jobs accurately when margins are tight. Getting CIS wrong means either overpaying subcontractors or facing HMRC penalties, so the right software matters more here than in most sectors.
We have ranked the accounting tools that handle UK construction and CIS best in 2026, weighing how cleanly they calculate and submit CIS against job costing, subcontractor management and price. For a builder, a contractor or a construction firm, these are the options worth your attention.
What to look for in UK accounting software
Start with Making Tax Digital. Any accounting software you choose should be recognised by HMRC for MTD for VAT, and increasingly for Income Tax too, so that you can keep digital records and file returns directly rather than through a workaround. This is now a baseline requirement rather than a nice to have, and every option we recommend clears it.
Beyond compliance, weigh four things. First, the real cost, which means the renewal price excluding VAT rather than a first year discount, and whether payroll is included or charged separately, because that single factor can flip which product is cheapest. Second, bank connectivity and reconciliation, since this is where you will spend most of your time and a good feed saves hours every month. Third, whether it handles any sector specifics you need, such as CIS for construction or multi currency for importers. And fourth, whether your accountant already knows it, because collaboration is far smoother when you both work in the same system.
How we assessed these tools
Every product here was judged on the things that actually decide whether software works for a UK business: the real published price excluding VAT, how it handles HMRC obligations such as Making Tax Digital, RTI or CIS where relevant, the depth of the core job it is bought for, how quickly a non specialist can get productive, and the quality of UK support. We read each vendor's own pricing pages rather than repeating third party figures, and we weight verified user ratings from people who run these tools day to day.
We also try to be honest about fit rather than crowning a single winner, because the right tool for a ten person business is rarely the right tool for a two hundred person one. Each entry below carries its real starting price, its current Assaylist rating and a clear note on who it suits and where it falls short, so you can match the software to your own situation rather than to an average. Where we earn a commission from an outbound link we say so, and it never changes the order of this list.

3. Sage Accounting
Sage Accounting handles CIS management and submission on its paid tiers, and with payroll bundled it covers both your subcontractor deductions and your employee PAYE from one place. For a construction business with staff as well as subcontractors, that consolidation is genuinely useful.
What you get: Sage's main cloud accounting product for small UK businesses. Payroll for one employee and the Sage Copilot assistant are now bundled into all three tiers. It holds a 4.0 out of 5 rating across 394 reviews on Assaylist.
Pricing: The plans run Start at £20, Standard at £43 and Plus at £59 per month, excluding VAT.

4. Sage 50 Accounts
Sage 50 Accounts suits an established construction business that needs serious job costing, stock control for materials and multi company reporting. Its depth outclasses the cloud tools, and for a firm running multiple projects and holding significant materials stock, that capability earns its higher price.
What you get: Sage's desktop accounting software for established small and medium UK businesses. Deep stock, project costing and multi company reporting that the cloud products do not match. It holds a 4.1 out of 5 rating across 462 reviews on Assaylist.
Pricing: The plans run Sage 50 Accounts Standard at £115 and Sage 50 Accounts Professional at £234 per month, excluding VAT.
Why we rate it:
- Advanced stock management
- Project costing
- Multi company reporting
- AI document capture
Bear in mind: the price is only justified if you use the depth.

5. FreeAgent
FreeAgent supports CIS and is built for the contractor and small limited company, with its tax timeline keeping every liability visible. For a construction contractor operating through a limited company, especially one banking with a qualifying group and getting it free, it is an excellent fit.
What you get: A UK accounting product owned by NatWest, aimed squarely at limited company contractors and sole traders. Free for as long as you bank with the group. It holds a 4.0 out of 5 rating across 497 reviews on Assaylist.
Pricing: The plans run Free with NatWest, RBS, Ulster or Mettle at free, Sole trader at £19 and Limited company at £33 per month, excluding VAT.
Why we rate it:
- Free with a NatWest, RBS, Ulster or Mettle account
- Built for UK limited company contractors
- Tax timeline showing what is owed and when
- Corporation Tax and dividend handling
Bear in mind: it does not scale to a larger firm with stock and many staff.

How much should you budget?
Cloud accounting for a UK small business typically costs between fourteen and sixty pounds a month excluding VAT, depending on the tier and whether payroll is included. Entry plans around fourteen to twenty pounds suit a sole trader or a simple limited company, mid tiers around forty pounds add multi user access, quotes, forecasting and CIS, and top tiers near sixty pounds bring inventory and multi currency. Free options exist for the smallest businesses, notably QuickFile and the free tiers of Zoho Books and Sage Sole Trader.
The figure to watch is the renewal price rather than the introductory discount, since several vendors advertise heavy first year savings and then step up sharply. Factor payroll into the comparison too, because a product that bundles it can undercut one that charges separately once you add a payroll subscription. Budget on the total you will actually pay in year two, not the headline you see at sign up.
Our verdict
For most UK construction businesses, Xero and QuickBooks Online are the strongest choices, both handling CIS well, with QuickBooks notable for including it from the entry tier and Xero for its job costing through Projects. Sage Accounting is the pick if you want payroll bundled alongside your CIS.
Larger construction firms with significant job costing and materials needs should consider Sage 50 Accounts for its depth, while contractors operating through a limited company will find FreeAgent an excellent fit. Match the tool to whether you are a contractor, a small firm or an established business, and make sure CIS submission is included at the tier you actually need.
The bottom line
For most UK construction businesses, Xero and QuickBooks Online are the strongest choices, with QuickBooks notable for including CIS from the entry tier and Xero for its job costing. Larger firms with real materials and job complexity should consider Sage 50 Accounts, and limited company contractors will find FreeAgent an excellent fit. Whatever you choose, confirm that CIS submission is included at the tier you actually need, because that is where the sector specific value lives.
Frequently asked questions
What accounting software handles CIS?
Xero, QuickBooks Online, Sage Accounting, Sage 50 Accounts and FreeAgent all handle the Construction Industry Scheme. QuickBooks includes CIS from its entry tier, while Xero handles it from Ignite upwards. Each calculates deductions and helps with subcontractor reporting to HMRC.
Does construction accounting software submit CIS to HMRC?
Yes. The leading tools calculate CIS deductions and support submission to HMRC, including subcontractor verification and monthly returns. This automation is one of the main reasons a construction business should use CIS aware software rather than a general accounting tool or spreadsheet.
What is the best accounting software for a small builder?
For a small builder, QuickBooks Online is a strong choice because it includes CIS from the entry tier, and Xero is excellent for its job costing through Projects. FreeAgent suits builders operating as a limited company contractor. All handle CIS deductions and Making Tax Digital.
Can accounting software track job costs?
Yes. Xero's Projects module and QuickBooks' project profitability tracking both let a construction business track costs and margin per job, which is essential when quoting fixed price work. Sage 50 Accounts offers deeper project costing for larger firms with more complex jobs.
Do I need special software for the Construction Industry Scheme?
You need software that is CIS aware, which most leading UK accounting tools now are. CIS involves verifying subcontractors, applying the correct deduction rate and filing monthly returns, and dedicated support for this avoids costly errors. General accounting software without CIS features is not sufficient for a construction business.
