What Is a Mobile Invoicing App?
A mobile invoicing app is software that runs on your phone to create, customise, and send invoices to clients without needing a computer or office. Invoicr: Invoice & Billing App is a UK invoicing platform built specifically for sole traders, plumbers, electricians, gardeners, and other self-employed professionals who need to bill clients on the move.
How Mobile Invoicing Works
Mobile invoicing apps let you draft an invoice, add your client's details and line items, and send it instantly from your phone. Most apps let you track payment status and send reminders when invoices are overdue. Invoicr is built for the UK and focuses on making payment collection easier for tradespeople and freelancers. Instead of using card processors that charge 2 to 3 percent per transaction, Invoicr uses UK open banking for bank-to-bank payments, which costs significantly less. On a £500 invoice, you pay around £4 instead of £12.50.
Key Features of Invoicr
Invoicr offers mobile-first invoicing designed for UK sole traders. The free tier includes 5 invoices per month and space for 3 customers, with no credit card required to start. The Pro plan (£9.99 a month or £79.99 a year) unlocks unlimited invoices, automated payment reminders, the ability to send invoices via WhatsApp, and quote templates. The Business plan adds 5 team seats, VAT and CIS tax compliance features, and export tools for accountants. Every tier includes a client portal where your customers can pay you directly via their bank account.
Who Should Use Invoicr
Invoicr is built for UK freelancers and tradespeople who work on site or move between clients. Plumbers, electricians, gardeners, handymen, mobile mechanics, decorators, and cleaners all benefit from issuing invoices straight from their phone. The app is also suited to consultants, contractors, and small business owners who bill clients regularly and want to reduce payment processing costs. If you're a UK sole trader who currently loses money to card-processor fees, mobile invoicing can help you keep more of what you earn.
Mobile Invoicing vs. Desktop Invoicing
Desktop invoicing tools require you to sit at a computer or log in via a web browser. Mobile invoicing apps are optimised for small screens, touch input, and offline use, so you can issue an invoice from a client's driveway or site. Invoicr is iOS and Android native, meaning it's built directly for phones rather than adapted from a web tool. This makes it faster to open, quicker to use, and more reliable when your internet connection is weak. For UK tradespeople who spend most of their day away from an office, this difference matters.
Why Bank-to-Bank Payments Matter
Most invoicing apps integrate with card payment processors like Stripe or Square. These processors charge a percentage of every transaction, typically 1.5 to 3 percent. Invoicr's flagship payment method is UK open banking, which lets your clients pay you directly from their bank account. The fee is fixed and much lower than card processing, so you keep more of the money your clients owe you. This approach is particularly valuable for tradespeople who handle invoices of £200 to £1,000, where card fees quickly add up.
