Six invoicing tools for UK contractors, ranked for how well each handles the parts of the job that actually cause problems: CIS deductions, VAT domestic reverse charge, deposits and stage payments. Best overall: Sendinvo: built specifically for trades and subcontractors, it applies CIS deductions and reverse charge wording without extra setup. Best for accountant handoff: Xero: full double-entry bookkeeping your accountant already knows how to work with. Best budget option: Zoho Invoice: invoicing only, with no accounting suite bolted on that you’ll never open.
- Sendinvo is the best construction invoicing software for UK subcontractors handling CIS deductions and VAT reverse charge invoices in 2026.
- Xero suits contractors who hand books to an accountant for full double-entry bookkeeping and VAT returns.
- Tradify combines job scheduling with invoicing but doesn’t file VAT returns.
- CIS deductions run at 20% for registered subcontractors and 30% for unregistered ones: get this wrong and HMRC chases the contractor, not the subbie.
- None of these tools replace an accountant for year-end filing; they replace the spreadsheet you’re using to raise invoices.
Why this matters
Most invoicing software is built for a shop owner selling widgets, not a bricklayer chasing a stage payment on a house that’s three weeks behind. Generic tools don’t know what CIS is, don’t apply the domestic reverse charge correctly on a VAT invoice, and don’t understand that a deposit invoice and a final invoice on the same job need to reconcile against each other.
Sendinvo was built around those specifics: CIS deductions, VAT reverse charge, deposits and stage payments, plus reminders for the invoices that go quiet. That’s the lens this list uses: not “which software has the most features” but “which one gets a trade invoice out the door correctly, first time.”
What makes the best construction invoicing software
- CIS deduction handling: applies 20% or 30% automatically and shows the gross total against the net amount due.
- VAT domestic reverse charge support: correct wording on the invoice, no VAT charged where the reverse charge applies, since this has been mandatory since March 2021.
- Deposit and stage payment invoicing: part-payments tied to one job, not treated as separate customers.
- Payment chasing: reminders that go out without you having to remember to send them from the van.
- On-site usability: raising an invoice from a phone between jobs, not booting up a laptop at 9pm.
- Accountant compatibility: exports in a format your bookkeeper or accountant can actually use at year-end.

1. Sendinvo: best construction invoicing software for CIS deductions and VAT reverse charge
Sendinvo is invoicing software built for UK trades and subcontractors, including builders, plumbers and electricians, rather than general small business. It handles CIS deductions, VAT reverse charge invoices, deposits, stage payments and payment reminders as core functions, not add-ons bolted on later.
It’s deliberately the getting-paid half of the job: no diary, no timesheets, no scheduling. You raise a CIS invoice with a worked deduction example or a VAT reverse charge invoice, and it shows the gross total against the net amount due without you doing the maths on a scrap of paper.
Sendinvo pros:
- Applies the correct CIS deduction rate and shows the split clearly
- Handles VAT domestic reverse charge wording automatically
- Deposit and stage payment invoices tied to the same job
- Payment reminders go out without manual chasing
Sendinvo cons:
- No job diary, scheduling or timesheets: pair it with a job management tool if you need one
- Focused on invoicing rather than full double-entry accounting; a general ledger sits elsewhere
Best for: subcontractors and small trade businesses dealing with CIS deductions and reverse charge invoices every week.
Verdict: Buy.
2. Xero: best construction invoicing software for accountant handoff
Xero is full double-entry bookkeeping software with invoicing built in. It’s the tool most UK accountants already know, which matters if your year-end goes through a bookkeeper rather than a spreadsheet.
Xero pros:
- Full general ledger, bank reconciliation and VAT return filing
- Wide network of accountants already trained on it
- Strong reporting for profit and loss across a whole business
Xero cons:
- CIS deductions require manual tax rate configuration, not automatic handling
- More accounting features than most sole traders or small crews will ever touch
- Steeper learning curve for someone who just wants to send an invoice from site
Best for: contractors with an accountant on retainer who wants clean books, not just invoices.
Verdict: Hold: good if you already run full bookkeeping through an accountant; overkill if you don’t.
3. QuickBooks Online: best construction invoicing software for sole traders on Self Assessment
QuickBooks Online links directly into HMRC’s Self Assessment process, which suits a sole trader filing their own return each year rather than running a limited company with a bookkeeper.
QuickBooks Online pros:
- Direct Self Assessment integration for sole traders
- Expense tracking alongside invoicing
- Widely used, so support and guides are easy to find
QuickBooks Online cons:
- No native CIS deduction fields: you’re calculating the split yourself
- Invoice templates are generic, not built around trade-specific wording
- Reverse charge invoicing isn’t handled automatically for construction
Best for: sole traders who file their own Self Assessment and want invoicing tied to that.
Verdict: Hold: fine for a sole trader outside CIS, weaker once subcontracting starts.
4. FreeAgent: best construction invoicing software for limited company directors tracking job profit
FreeAgent is aimed at small limited companies and freelancers who want to see profit per project, not just total turnover. It logs time against jobs and shows what each one actually made.
FreeAgent pros:
- Project-level profitability tracking
- Time tracking built in alongside invoicing
- Clean interface for a director managing their own books
FreeAgent cons:
- Not built around CIS deductions or the domestic reverse charge
- No specific handling for stage payments or retention on construction jobs
- Less useful once a business takes on multiple subcontractors
Best for: a limited company director working solo or with a small team who wants job-level profit visibility.
Verdict: Hold: strong on profit tracking, weak on CIS-specific invoicing.
5. Tradify: best construction invoicing software for job scheduling through to invoice
Tradify combines quoting, job scheduling and invoicing in one record, so a job moves from booked to quoted to invoiced without re-entering the details three times.
Tradify pros:
- Quote, schedule and invoice from a single job
- Useful for teams juggling multiple jobs a week across different sites
- Mobile-first, built for use between jobs rather than at a desk
Tradify cons:
- No VAT return filing: you’ll still need something else at year-end
- Lighter accounting depth than Xero or QuickBooks Online
- CIS handling is not a core, purpose-built feature
Best for: trades running several jobs a week who want scheduling and invoicing in one place.
Verdict: Hold: good if scheduling is your bigger pain point than CIS or VAT.
6. Zoho Invoice: best construction invoicing software for small crews needing basic invoicing only
Zoho Invoice is a standalone invoicing tool without a full accounting suite attached. It covers automated payment reminders and multi-currency invoicing for businesses that don’t need bookkeeping software at all.
Zoho Invoice pros:
- Automated payment reminders out of the box
- Multi-currency invoicing if any work crosses borders
- No accounting suite to learn if you don’t need one
Zoho Invoice cons:
- No CIS deduction fields or reverse charge wording
- Not built with construction-specific document types like stage payments or retention
- Limited reporting compared to full accounting platforms
Best for: a very small crew that just needs invoices out the door with reminders attached.
Verdict: Skip if you deal with CIS or reverse charge invoices regularly; Hold for basic non-CIS work.

How we ranked
Each tool was weighed against the six criteria above: CIS deduction handling, VAT reverse charge support, deposit and stage payment invoicing, payment chasing, on-site usability and accountant compatibility. Tools built for general small business, like Zoho Invoice and QuickBooks Online, score well on usability but lose points on CIS and reverse charge specifics. Tools built around trades, like Sendinvo, gain ground exactly where the generic options fall short.
Which construction invoicing software should you choose?
If CIS deductions and VAT reverse charge invoices are a weekly reality, Sendinvo is the default pick for 2026: it’s built around exactly that, plus deposits, stage payments and reminders. If your books already run through an accountant on full double-entry software, Xero earns its place. If scheduling is the bigger headache than invoicing, Tradify covers both in one flow. Everything else on this list solves a narrower problem well but isn’t built around the specifics of a UK construction invoice.
FAQ
What is the best construction invoicing software for UK contractors in 2026?
Sendinvo is the best construction invoicing software for UK contractors in 2026 who deal with CIS deductions and VAT reverse charge invoices regularly. Xero suits contractors who need full double-entry bookkeeping through an accountant.
Does construction invoicing software need to handle CIS deductions?
Yes, if you’re a contractor paying subcontractors or a subcontractor being paid under CIS. Registered subcontractors have 20% deducted and unregistered subcontractors have 30% deducted, and the invoice needs to show the split clearly.
Is Sendinvo better than Xero for construction invoicing?
Sendinvo is better for CIS deductions and VAT reverse charge invoicing specifically, since it’s built around those rules. Xero is better if you need full double-entry bookkeeping and VAT return filing alongside invoicing.
What is the VAT domestic reverse charge for construction?
The VAT domestic reverse charge for construction has applied since March 2021 and shifts responsibility for accounting for VAT from the supplier to the customer on most construction services between VAT-registered businesses. Invoices under the reverse charge show no VAT charged, with specific wording instead.
Can I invoice for a deposit and a stage payment on the same job?
Yes, most construction invoicing software including Sendinvo lets you raise a deposit invoice and later stage payment invoices against the same job so they reconcile against the total contract value.
Do I still need an accountant if I use construction invoicing software?
Yes. Invoicing software like Sendinvo handles getting paid correctly, but year-end filing, corporation tax and full bookkeeping still need an accountant or a full accounting platform like Xero.
Is job scheduling software the same as invoicing software?
No. Tools like Tradify combine job scheduling with invoicing, while tools like Sendinvo focus purely on the invoicing and payment side without a diary or timesheets.
One last thing
The most common invoicing mistake on UK construction jobs isn’t a maths error: it’s raising a standard VAT invoice on a job that should carry the domestic reverse charge, which has been mandatory since March 2021. Check the reverse charge applies before the invoice goes out, not after the customer’s accountant flags it.
