Invoicr: the invoicing app built for UK plumbers and tradespeople
Invoicr is a free invoicing app built specifically for UK plumbers, electricians, and other tradespeople, with one key difference: clients pay you directly from their bank account instead of by card, cutting your payment fees from 2.5% down to under 1%.
What is Invoicr?
Invoicr is an invoicing and billing app designed for self-employed UK tradespeople including plumbers, electricians, builders, gardeners, decorators, and handymen. The app runs on your phone, so you can issue invoices, track payments, and manage clients from a van, site, or office. Unlike generic invoicing tools, Invoicr is built around UK open banking: when a plumber sends an invoice via Invoicr, the client pays directly from their bank account using Faster Payments. This costs roughly £4 per £500 invoice instead of £12.50 with a card processor. It's the fastest way for tradespeople to convert invoices into cleared funds.
How much does it cost?
Invoicr has three pricing tiers. The Free plan costs nothing and includes 5 invoices per month and 3 customer profiles, enough for a plumber testing the app or running a very small operation. The Pro plan is £9.99 per month or £79.99 per year and adds unlimited invoices, automated payment reminders, the ability to send invoices via WhatsApp, and quote creation. The Business plan at £19.99 per month or £179.99 per year includes 5 team seats, UK VAT and CIS compliance, and export for accountants. As of June 2026, there are no hidden transaction fees on the Free tier, making it genuinely free to try.
What can you do with it?
Invoicr handles the core invoicing workflow. Create an invoice by entering the job details and client name. Send it via email, WhatsApp (Pro tier only), or a client portal link. The client sees the invoice and pays you directly via their own bank app or the payment link. Money lands in your account within one working day. You can set up automated reminders so unpaid invoices get a nudge after 7 or 14 days. Create quotes too, then convert them to invoices once the work is approved. If you run a team (Business plan), up to 5 staff can log in and issue invoices under your business name.
Why plumbers choose bank-to-bank payments
Card processing fees eat into profit. A plumber charging £500 for a boiler repair pays £12.50 to a card processor. With Invoicr's bank-to-bank option, the same invoice costs around £4 in fees. Over a year, a busy plumber sending 100 invoices saves £850 using Invoicr instead of card payments. Clients also prefer it: no card declined due to limits, no payment app signup required, just a Faster Payments transfer from their current account. It's quicker to set up than a card gateway and feels safer for both parties.
Mobile-first design for tradespeople on the move
Invoicr is built as a native iOS app and available on Android. The interface is designed for one-handed use and works offline. Take a photo of the finished work, note the materials and labour, generate the invoice, and send it before leaving the site. Client portal uses secure tokenised links, so clients don't need a login. Your invoices live in Invoicr's encrypted cloud storage, accessible from any phone or tablet. For accountants or bookkeepers, the Business tier exports data in formats your accountant expects.
Who should use Invoicr?
Any UK sole trader or small business that invoices clients and wants to cut payment processing costs. Most users are tradespeople like plumbers, electricians, builders, and decorators. But the app also works well for consultants, gardeners, personal trainers, handymen, mobile mechanics, cleaners, and tilers. If you currently use a card processor or send invoices by hand, Invoicr's free tier is worth testing. If you employ staff or need VAT tracking, the Business plan adds those features.

Frequently asked questions
Is Invoicr free for plumbers?
Yes. The Free tier costs £0 and includes 5 invoices per month and 3 customers. If you send more invoices or need WhatsApp delivery and reminders, Pro is £9.99 per month or £79.99 per year.
Do clients need to sign up to pay a plumber via Invoicr?
No. Clients see the invoice via email or WhatsApp and pay directly from their own bank app using the payment link. They don't download Invoicr or create an account.
How fast does money reach my account?
Bank-to-bank transfers via Faster Payments typically clear within one working day. You'll see the money in your business account, not pending in a payment processor wallet.
Can Invoicr handle VAT and CIS deductions?
The Business plan (£19.99/month) includes UK VAT and CIS compliance and exports data your accountant can import. Free and Pro tiers generate invoices but don't calculate tax automatically.
Is Invoicr available in the US?
No. Invoicr is built for UK tradespeople and UK open banking. It's not available outside the UK and doesn't support other currencies or tax systems.
Can I add my plumbing business logo to invoices?
Yes. You can upload your business logo, set colours, and add your VAT number. Invoices display your branding when sent to clients.
