Invoicing for tile installers

Invoice Koi is an invoice app for tile installers, where the sq ft is the quote and the leveling and the tanking are lines of their own rather than an unexplained increase.

The iPhone app is coming to the App Store.

Tiling is priced per square foot right up until it is not: the floor that needed leveling, the wet room that needed tanking, the fifteen cuts around a window. The invoice has to show that work or it looks like the price went up for no reason.

02Why tile installers use it

Three things that
save the evening.

A rate per square foot, kept

Wall and floor rates in the price book with sq ft as their unit. Type the area, the line does the rest, and the totals resolve underneath.

Prep that shows on the document

Leveling and tanking under their own heading with a subtotal, so the extra day reads as work rather than as a bigger number.

Quoted then billed, once

The estimate converts to the invoice with the lines and the terms intact, so what you bill is what was agreed.

03 · Questions

Asked by tile installers.

Can I invoice per square foot?

Yes. A price-book line carries its own unit, so sq ft sits alongside hourly labor and per-job materials on the same invoice.

How do I bill for unexpected preparation?

Add it as its own grouped section with a subtotal. The customer sees what the extra day was, not just a larger total.

Does the customer need an app?

No. They get a PDF, by email or through any messaging app. There is no portal and nothing for them to sign up to.
