Create Professional Invoices Online
Build invoices in seconds with our free invoice generator. Add customers, products and services, apply VAT and discounts, then send a polished PDF to your customer.
Creating invoices should not take all evening
You finish a job, get home, and now you have to create an invoice. You open a template, type in the customer details, list the work you did, work out the VAT, calculate the total — and by the time you are done, you have spent twenty minutes on something that should take two.
Most invoice generators stop there. They produce a document but do not help you track whether it was paid, remind you when it is overdue, or connect the invoice to the quote and the mileage that led to it.
The result is invoices that look fine but exist in isolation — disconnected from your quotes, your appointments and your mileage records.
An invoice generator that does the hard work for you
MileageCalendar includes a free invoice generator that lets you create a professional invoice in under a minute. Select a customer, add your line items, and the subtotal, VAT and total are calculated instantly. You see a live preview as you type.
When you are ready, you can download a polished PDF or send the invoice directly to your customer. The invoice is saved in your account, so you can track its status — sent, viewed, paid — without opening a spreadsheet.
And because MileageCalendar connects your whole workflow, you can convert an accepted quote into an invoice with one click, add mileage and expenses to the same document, and record the payment when it arrives.
