Best App for Sending Invoices on the Go
Invoicr is a mobile-first invoicing app designed for UK self-employed people and small businesses who need to create and send invoices from anywhere. Built for your phone, not a spreadsheet or desktop software, it lets you invoice clients in minutes without leaving the job site.
Why Invoicr Works for On-the-Go Invoicing
Most invoicing solutions are built for office desks. Invoicr is built for your pocket. As a UK freelancer, sole trader, or tradesperson, you need to send an invoice from the van, the building site, or between client visits. The app handles quick invoice creation without fiddly navigation. You add your client details, set your rate, and send a payment link via Stripe in seconds. No waiting until you get home. No logging into a web portal on a tiny screen. Just invoice, send, and move on.
Everything Else Your Business Needs, Too
Invoicing alone isn't enough to run a business. Invoicr includes expense tracking with receipt capture, so you can snap a photo of your materials or tools as you buy them. The mileage logger records your business travel automatically for tax purposes. UK VAT calculations happen in the background based on your settings. You build a customer database so repeat clients are already set up next time. If you're quoting before invoicing, the quotation builder gets you there first. All of this stays on your phone, synced and accessible whenever you need it.
Payment Links That Work Immediately
When you send an invoice via Invoicr, clients get a secure Stripe payment link they can click from their phone or computer. You see payments arrive in real time. No chasing, no manual bank reconciliation, no invoices sitting unpaid for weeks. For tradespeople, plumbers, electricians, and builders, faster payment means better cash flow for your next job.
Free to Start, Pro When You're Ready
The free tier gives you enough monthly invoices to test how the app fits your workflow. When you're invoicing regularly and need unlimited sends plus advanced reports, the Pro tier unlocks everything. You're not forced into a subscription before you know if mobile invoicing works for you. Most UK self-employed users find the free tier covers their needs, while growing businesses move to Pro as their client list expands.
Works on iOS and Android
Whether you use iPhone or Android, Invoicr is available on both platforms. Download it once, and your business invoicing is in your pocket. Your customer database, expense records, and invoice history sync across devices, so you can switch between your phone and tablet without thinking about it.
Built for UK Self-Employed, Not Accountants
You'll notice Invoicr doesn't try to be QuickBooks or Xero. It's not an enterprise platform. It's an app designed specifically for UK freelancers, sole traders, and small business owners who work away from a desk. That focus means every feature serves the person in the field, not a back-office bookkeeper. If you need advanced payroll or company accounts, those tools exist elsewhere. If you need to send a professional invoice to a client from a building site, Invoicr was built for exactly that.

Frequently asked questions
Can I send invoices offline and sync later?
Invoicr is designed to work best with an internet connection so payment links generate immediately and clients receive invoices straight away. If connectivity is patchy on site, draft your invoice offline and send once you have signal.
Does Invoicr handle VAT automatically?
Yes. The app calculates UK VAT based on your settings and applies it to invoices. You can toggle VAT on or off per invoice depending on whether you're VAT registered.
What happens if I reach my free tier invoice limit?
Once you hit the monthly cap on free invoices, you can either wait for next month or upgrade to Pro for unlimited invoicing. Past invoices remain accessible in either tier.
Can I create quotes as well as invoices?
Yes. Invoicr includes a quotation builder so you can send clients a formal quote before converting it to an invoice once work is approved.
Do I need to log mileage manually every day?
The mileage logger in Invoicr lets you record trips as you make them, or add them in bulk at the end of the week. You control the granularity; many users log monthly to keep tax records clean and simple.
Is my invoice data secure on my phone?
Invoicr stores your data securely and syncs it across your devices. Your payment processing runs through Stripe, which is PCI compliant. Customer details stay on your phone unless you choose to share an invoice or payment link.
