Invoicing for UK CIS subcontractors: Invoicr
Invoicr is a free invoicing app built for UK sole traders and subcontractors including those under the Construction Industry Scheme, letting you issue invoices and receive payments direct to your bank account with minimal fees.
What Invoicr does for CIS subcontractors
Invoicr is purpose-built for UK tradespeople and subcontractors working under CIS rules. The app lets you create and send invoices from your phone in seconds, then get paid via direct bank transfer instead of card processing. That matters for CIS work: on a £500 invoice, bank-to-bank costs around £4 compared to £12.50 with a card processor. The free tier includes 5 invoices per month and 3 customers. If you need more, the Pro plan (£9.99 monthly or £79.99 yearly) unlocks unlimited invoices, automated payment reminders, and WhatsApp delivery. The Business plan (£19.99 monthly or £179.99 yearly) adds CIS compliance features, VAT handling, and accountant export for your tax return preparation.
CIS compliance and tax reporting
Invoicr's Business plan includes built-in CIS and VAT compliance, which means the app formats your invoices and records according to HMRC Construction Industry Scheme rules. This matters because CIS subcontractors face specific invoicing and deduction certificate requirements. The app's accountant export feature lets you send your invoice records directly to your accountant or bookkeeper in a format they can use for your self-assessment return. As of June 2026, this feature removes the need to manually collate your invoices or copy data into a spreadsheet before tax time. For subcontractors handling multiple clients or projects, this automated export saves hours each year.
Bank transfer payments instead of card fees
The core reason Invoicr exists is to cut payment processing costs for UK tradespeople. Instead of asking clients to pay by card (which costs 2.5% or more), Invoicr uses UK open banking to let clients pay direct from their bank account to yours. Your client taps 'pay now', authenticates with their bank, and the money arrives the same day or next working day. You pay a flat fee per transaction (around £1.50 per invoice on average) rather than a percentage. For subcontractors issuing dozens of invoices monthly, this compounds: £500 invoices processed 10 times a month saves you roughly £40 to £80 every month compared to a standard card processor.
Mobile-first invoicing for tradespeople on site
Invoicr runs natively on iOS and Android, so you can issue an invoice from your van or job site without logging into a laptop. Create an invoice, attach a photo of work completed, add materials or labour line items, and send it via WhatsApp or email within a few minutes. Your client receives a link to a secure portal where they can view the invoice, download a PDF, and pay immediately if they have the bank transfer method enabled. The app stores all invoices in a timeline, so you can search and resend past invoices or check payment status anytime.
Free invoicing with no credit card required
Getting started with Invoicr costs nothing. The free tier gives you 5 invoices per month, 3 customer profiles, and full access to bank-to-bank payments. Many sole traders and part-time subcontractors stay on the free plan indefinitely. If your invoicing volume grows beyond 5 per month, or you need WhatsApp delivery and automated reminders, you can upgrade to Pro (£9.99/month) with no lock-in contract. The Business plan is designed for teams or subcontractors working across multiple projects with shared access and full VAT and CIS reporting.
Not a deduction certificate generator
If you are searching for a tool that auto-generates HMRC deduction certificates (the documents CIS contractors issue to main contractors), Invoicr is not that tool. Invoicr is an invoicing and payment collection app for the subcontractor side: it helps you issue invoices, receive payments, and track what you've billed. Deduction certificates and CIS tax treatment are handled separately through your accountant or tax software during self-assessment. What Invoicr does provide is clean, compliant invoice records and payment data that your accountant can use to calculate your tax position under CIS rules.
