Invoice Koi

Invoicing for handymen

The problem is not that any one job is complicated, it is that there are six of them and the paperwork for all six lands at once, in the evening, when the details have gone. An invoice written in the drive is an invoice that is right.

What handymen
put on an invoice.

These go in your price book once, with your own prices against them. After that a line is one tap: the item, the description, the unit and the price fill themselves, and the totals resolve underneath.

Prices are yours. Invoice Koi ships a handful of round placeholder lines to start from and never fills your book with figures you did not set.

02Why handymen use it

Three things that
save the evening.

Hours tracked, then billed

Track time against a client and turn it into a line on the invoice, instead of writing the same figure down twice and trusting the second copy.

Sent from the drive

A PDF out through your own mail or any messaging app, before you have started the engine. The mail sheet opens and you press send.

No signal, no account, no wait

It all works on the phone before you have made an account, and keeps working in a cellar with no bars.

03 · Questions

Asked by handymen.

How fast can I send an invoice?

Pick the client, tap the rates you already charge, send. The address, the terms, the tax and the next number come with the client, so the only thing you choose is the work.

Can I send it by WhatsApp instead of email?

Yes. The PDF goes out through the share sheet, so any messaging app on the phone can carry it.

Is it really free?

Free covers a hundred invoices a year and uncapped estimates, clients and reports. Pro lifts the count and adds what leaves the phone: your photographs on a server, the reading, and the paperwork a client signs or opens.
