Simple Invoicing Software for Small Businesses
Create, send and track professional invoices without the admin headache. Built for sole traders, freelancers, tradespeople, consultants and mobile workers who want to get paid faster.
Invoicing should not be a separate chore
If you run a small business, invoicing is just one of many admin tasks competing for your evening. You create the invoice, send it, wait for payment, chase it when it is late, record the payment when it arrives — and then do it all again next week.
Most invoicing software treats invoices as standalone documents. They do not connect to the quote that led to the work, the appointment in your calendar, the mileage you drove to get there or the expenses you incurred. You end up entering the same information in multiple places.
For sole traders and small businesses, this disconnected admin is not just annoying — it costs you time you could spend on paying work, and it increases the chance of mistakes and missed payments.
Invoicing connected to your whole workflow
MileageCalendar is invoicing software built for UK small businesses. It connects your invoices to the rest of your workflow — your quotes, your appointments, your mileage and your expenses — so you enter each detail once and it flows through automatically.
You can create an invoice from scratch, convert an accepted quote with one click, add mileage and expense lines to the same document, and send a polished PDF to your customer. When the payment arrives, you record it against the invoice and your records stay up to date.
The result is less admin, fewer mistakes and faster payment. You spend minutes on invoicing instead of hours, and nothing falls through the cracks.
