Invoicing for flooring fitters

Invoice Koi is an invoice app for flooring fitters, splitting the supply from the fitting and the uplift from both, on a document the customer can follow.

The iPhone app is coming to the App Store.

Supply and fit is one price to the customer and three to you: the floor, the underlay, and the day it takes to lift what was there and get rid of it. Splitting those on the invoice is the difference between a quick payment and a phone call.

02Why flooring fitters use it

Three things that
save the evening.

Supply-and-fit and fit-only, both kept

Two lines in the price book, each with its own m² rate, so a customer supplying their own floor is priced correctly in one tap.

Uplift shown as work

The old carpet and the skip get their own heading and subtotal instead of vanishing into a rate the customer thinks is high.

A document that looks like your business

Nine templates, your logo and your accent colour, all on the one subscription, and the preview is the PDF, so there are no surprises.

03 · Questions

Asked by flooring fitters.

Can I quote supply and fit separately from fitting only?

Keep both as price-book lines with their own square-metre rates and pick the one the job needs.

Can I turn a measure-up into an invoice?

Write it as an estimate. When it is accepted it converts to an invoice carrying the lines, the client, the tax and the terms.

Does it work offline?

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