Invoice Koi

Invoicing for electricians

An electrical job is rarely one line. There is a rough-in weeks before the trim-out, a panel replacement that is its own conversation, testing at the end, and a service call that may or may not turn into work. By the time the paperwork is written the invoice is the last thing anybody wants to be building out of a notes app.

What electricians
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 electricians use it

Three things that
save the evening.

Your rates, not a guess at them

The price book holds your hourly rate, your service call, your recessed light price. One tap puts the item, the unit and the price on the line, and the totals resolve underneath.

Rough-in and trim-out on one invoice

Group the lines under headings with their own subtotals, so a customer reading the document can see what the rewire cost and what the lights cost without asking you to break it down.

Written in the attic, sent from the truck

Everything is on the phone. You can build the whole invoice standing in a mechanical room with no bars and it is there, complete, when you get back to the road.

03 · Questions

Asked by electricians.

Can I turn an electrical estimate into an invoice?

Yes. An accepted estimate converts to an invoice with the lines, the client, the tax and your terms carried across, so a job that was quoted in March bills in April without being retyped.

Does it work without an internet connection?

Yes, entirely. Invoices are written, PDFs are drawn and the figures are worked out on the phone. Nothing waits on a server, and no screen needs a signal to open.

Do I need an account to use it?

No. Everything works before you make one. An account exists so a lost phone does not lose the books, and so a second device can pick them up. Nothing else is behind it.
