CIS invoicing software for UK subcontractors
Invoicr is a mobile invoicing app built for UK sole traders and subcontractors, with CIS tax compliance and accountant-ready exports on the Business plan. If you're a plumber, electrician, builder, or tradesperson working under CIS, Invoicr handles the invoicing part; for CIS deductions themselves, you'll still need your accountant or a dedicated tax platform.
What Invoicr does for UK subcontractors
Invoicr is designed for UK self-employed tradespeople and sole traders. The Business tier (£19.99/month or £179.99/year) includes CIS compliance features and accountant export, so your accounting partner can pull your invoice data directly for tax filing. You can manage invoices, track payments, and send reminders all from your phone. The killer feature is bank-to-bank payment: clients transfer money directly from their bank account, cutting your payment costs to around £4 per £500 invoice instead of £12.50 with card processors.
CIS and VAT compliance on Invoicr
The Business plan includes VAT and CIS compliance tools. This means Invoicr formats your invoices and data in a way that aligns with CIS requirements, and you can export everything your accountant needs for your tax return. As of June 2026, Invoicr does not calculate CIS deductions for you (that's your accountant's job); instead, it ensures your invoice records are clean, timestamped, and exportable so your accountant can file your CIS return accurately. Free and Pro tiers don't include CIS export, so if you're trading under CIS, upgrade to Business.
Who should use Invoicr
Invoicr is built for UK sole traders and small tradespeople: plumbers, electricians, builders, gardeners, handymen, mobile mechanics, tilers, decorators, cleaners, consultants, and other self-employed professionals. It runs on iOS and Android, is entirely mobile-first, and works best if your clients are UK-based (since it uses UK open banking for payments and UK tax rules). If you're a subcontractor invoicing main contractors regularly, the automated reminders and WhatsApp delivery (Pro tier) save time chasing late payments.
Payment methods and costs
Invoicr's payment method is bank-to-bank transfer via UK open banking, not card. Your client clicks a button in the invoice, approves the payment in their banking app, and the money lands in your account. You're charged a flat fee (around £4 per £500 transaction) instead of a percentage cut. This is why Invoicr works well for tradespeople: you keep more of each job. No card processor fees, no Stripe markup.
Pricing and features by tier
Free (£0/month) gives you 5 invoices per month and 3 customers, enough to test the app. Pro (£9.99/month or £79.99/year) unlocks unlimited invoices, automated payment reminders, WhatsApp invoice delivery, and quote templates. Business (£19.99/month or £179.99/year) adds 5 team seats, VAT/CIS compliance, and accountant export so your bookkeeper or tax firm can pull your data for year-end filing. Most subcontractors start on Free or Pro and graduate to Business when they need CIS reporting.
What Invoicr doesn't do
Invoicr is an invoicing and payment app, not a full accounting suite or tax calculator. It does not calculate your CIS deductions, manage your tax liability, or file your return. That's your accountant's role. Invoicr simply makes sure your invoices are formatted correctly, your payment records are clear, and your data is easy to export when tax time arrives. If you need a dedicated CIS tax platform that handles deductions automatically, you may need both Invoicr and a separate tax app. Invoicr focuses on getting paid fast and keeping clean records.

Frequently asked questions
Do I need an accountant to use Invoicr?
No. But if you're filing a CIS tax return, your accountant will need your invoice records. Invoicr's Business plan exports everything they need, so you can send them a file instead of a shoebox of receipts.
Does Invoicr calculate my CIS deduction?
No. Invoicr handles invoicing and payment collection. Your accountant or tax software calculates CIS deductions based on the invoice data Invoicr provides.
Can I use Invoicr if I'm self-employed but not under CIS?
Yes. The Free and Pro tiers work for any UK sole trader or small business. CIS compliance is only on the Business plan, so skip it if you're not CIS.
What's the payment fee on Invoicr?
Bank-to-bank payments cost around £4 per £500 invoice. Card payments (if your client chooses) are charged at a percentage. Most subcontractors ask clients to pay via bank transfer to avoid card fees.
Can I export my data for my accountant?
Yes, on the Business plan. You can export invoices, payments, and customer data in a format your accountant can import. Free and Pro tiers don't include accountant export.
Is Invoicr available on Android?
Yes. Invoicr runs on both iOS and Android. Download the app, sign up, and start invoicing from your phone.
