Invoicr: Invoicing App for UK Tradespeople with Offline Capability
Invoicr is a mobile invoicing app built for UK tradespeople, plumbers, electricians, and sole traders, with offline capability to create and manage invoices anywhere, even without internet.
What Invoicr does for tradespeople
Invoicr by MRVL is a free invoicing app designed specifically for UK self-employed workers and small tradespeople. You can create invoices, send them to clients, and get paid direct to your bank account using UK open banking instead of card processors. The app runs natively on your phone, so you work from site, van, or home. Unlike traditional invoicing software, Invoicr keeps costs low: on a £500 invoice, bank-to-bank payments cost around £4 instead of £12.50 with card fees. The Free tier gives you 5 invoices per month and space for 3 customers. As of 2026, Invoicr is used by builders, plumbers, electricians, gardeners, handymen, mobile mechanics, tilers, decorators, and cleaners across the UK.
Offline invoicing and mobile-first design
Invoicr is designed to work on the go. The app is mobile-first, meaning it's built around your phone or tablet first, not as an afterthought. You can draft invoices, add line items, and calculate totals offline. Once you reconnect to the internet, the app syncs your data and lets you send invoices via email or WhatsApp (on Pro and higher plans). This matters for tradespeople who move between job sites and can't rely on consistent connectivity. Your client portal works via a secure URL token, so clients can view invoices and pay you without needing an app themselves.
Bank-to-bank payments and lower fees
The core feature that sets Invoicr apart is bank-to-bank payment collection via UK open banking. Instead of asking clients to pay by card (which triggers 2.5% to 3% fees), you share a unique payment link. Clients pay you directly from their bank account to yours. The fee to you is a flat, low amount per transaction, not a percentage cut. For a tradesperson processing £2,000 in invoices monthly, this saves roughly £30 to £50 compared to card processing. The Free plan lets you use bank-to-bank payments right away. No card details required, no risk of chargebacks.
Plans and features that scale with you
Invoicr's Free tier (£0/month) includes 5 invoices per month, 3 customers, and bank-to-bank payments. 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 and CIS compliance, and direct export to your accountant. Most sole traders and small teams start on Free or Pro. The Business plan suits tradespeople hiring help or growing fast enough to need payroll and tax features.
UK compliance and tax readiness
Invoicr is built specifically for UK tradespeople, not as a global afterthought. It handles VAT compliance for registered traders and CIS (Construction Industry Scheme) deductions if you work in construction. The Business plan includes accountant export, so you can send your invoicing data straight to your accountant for year-end accounts. If you also manage client relationships on the go, linking to a mobile CRM like Konnect for Business lets you track jobs and invoices together. The app focuses on UK sole traders and small business owners; it does not cater to US or multi-currency invoicing.
When to choose Invoicr
Choose Invoicr if you are a sole trader or small tradesperson in the UK who wants to invoice and get paid from your phone without card fees eating your profit. It is not enterprise accounting software and does not replace full bookkeeping. If you need advanced reporting, project costing, or time tracking, you may outgrow it. Invoicr is for people who want a simple, cheap, phone-first way to invoice clients and collect payments via bank transfer. The Free tier lets you test it risk-free on 5 invoices per month.
