Invoicing for roofers

Invoice Koi is an invoice app for roofers, with the scaffold priced on a line of its own and an invoice that can be written one-handed in weather.

The iPhone app is coming to the App Store.

Roofing quotes are won or lost on how clearly the scaffold is priced, and roofing invoices are written in weather nobody wants to hold a phone in. Then a storm comes through and there are nine service calls in a week, all of them needing paperwork.

02Why roofers use it

Three things that
save the evening.

Scaffold priced where they can see it

Its own heading with its own subtotal, so the customer comparing three quotes can see what is access and what is roof.

Written on the roof, not at midnight

It all works with no signal, so the invoice is built while you are still looking at the job rather than reconstructed from memory that evening.

One nudge a day about what is late

At an hour you pick, the phone names what is overdue and what it comes to. Nothing goes to the customer unless you send it.

03 · Questions

Asked by roofers.

Can I quote scaffold separately?

Yes. Grouped line items give each part of the job its own heading and subtotal, so access, materials and labor read as three numbers.

Can I write an invoice with no phone signal?

Yes. Create invoices, estimates and PDFs offline on your phone. AI, cloud backup and payment collection need an internet connection.

Does it chase customers for me?

No, and it does not pretend to. It tells you once a day what is overdue, at an hour you choose. Anything that goes to a customer, you send.
