AI invoicing tools for roofers in the UK

Roofing invoices mix householders, insurers and main contractors, each with different rules. Householders pay on completion, insurers pay against a claim, and contractors deduct CIS and use the VAT reverse charge. An accounting app set up properly keeps all three straight.

Prices were re-checked on each provider's own page; the date is next to each one. Rules and figures from GOV.UK are linked where they're used.

Working for main contractors

As a subcontractor, you'll usually have CIS deducted at 20% if you're registered, 30% if not (GOV.UK). If you're VAT registered, your invoices to VAT-registered contractors normally use the reverse charge. Your invoices to homeowners don't (HMRC).

Insurance jobs

Put the claim reference, policyholder name and any excess on every invoice, and ask early whether the insurer pays you directly or pays the customer.

Chasing

For business customers, statutory interest on late payment is 8% plus base rate (GOV.UK). Put your terms on the quote so it isn't a surprise.

Questions

Which apps handle CIS?

QuickBooks lists CIS calculation and submission in all plans, and Xero lists CIS features on its pricing page. Checked 15 October 2026.

Can I charge a homeowner late payment interest?

Statutory interest applies to business customers. For homeowners, only if your terms say so.

Are these prices in pounds?

Not all. Where a provider only publishes US dollar prices we show dollars, so check the price in pounds at checkout.
