Hello. My name is gevvoihorry, the developer of "Invoice Maker."

I was originally a one-man construction company, working in blue collar jobs, and I had been issuing paper invoices for nearly 10 years.

I didn't own a computer, had little interest in IT, and thought that was enough.

But paper invoices can be a real pain.

If I make a mistake, I have to rewrite them from scratch, and the hassle of mailing them and postage costs can be significant.

"I wish there was an easier way to issue invoices."
With that in mind, I created this app for my colleagues who are struggling with the same issues.

This app is not designed for creating complex reports.
But instead, I focused on designing it so that anyone can use it quickly and easily.

[App Features]
・Input data in the same way as a paper invoice
・Simple design that only requires you to enter the billing month, issue date, and details
・Add up to 26 details. Automatic two-page invoice handling
- Complete the process using only your smartphone. No computer or printer required.
- No membership registration required. Start using immediately after downloading.
- Send PDFs directly via LINE or email.
- Manage all created invoices in one app.

- All personal information is stored on your smartphone. No external transmissions required.

[Recommended for]
- Those who still create invoices by hand.
- Freelancers (sole proprietors) and solo contractors who are not good with computers.
- Those working in on-site jobs such as construction, interior design, electrical engineering, plumbing, and scaffolding.
- Those who want to easily create invoices using only their smartphone.
- Those who want to streamline the process from writing to sending to managing.

This app is designed to be easy to use, with only the essentials.
