About

Built by Appicorn, for people who would rather be working

Invoice Maker started with a familiar frustration: the work is done, the client is happy, and the invoice still hasn’t been sent. We built the app that removes that gap — a professional invoice in about a minute, from the phone already in your hand.

Our approach

Invoice Maker is an easy invoice and estimate maker for iPhone. It creates professional PDF invoices, converts estimates into invoices, tracks paid and unpaid amounts with simple reports, and saves your clients and products for reuse. It is made by Appicorn, an independent app studio, for freelancers, trades and small businesses.

We are not accountants and we do not pretend to be. Our hope is simply that the app helps you send the invoice while the job is still fresh — and that you always know what you are owed.

What we value

Four things we hold to

Fast beats fancy

An invoice exists to get paid. We optimise for the moment you finish a job and want the admin over with.

Your data stays yours

No login, no cloud account, no client list sitting on a server you do not control. The app is a tool on your device.

Clarity over features

We would rather do invoicing, estimates, tracking and reports really well than bolt on a full accounting suite.

Honest about limits

Invoice Maker is not accounting software or legal advice. We say so plainly and point you to the right tool when you need one.

Privacy, plainly

An invoice holds your rates and your customers’ details. We think you deserve a plain answer about what happens to it, not a wall of legalese. Read the privacy policy for the full detail of what is and is not collected.
