Invoice Koi

Invoicing for plasterers

It is a trade that prices fast and bills slowly. The quote is worked out on a wall in two minutes, the job takes two days, and the invoice waits a week because writing it means sitting down with a laptop you do not own.

01On the document

What plasterers
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 plasterers use it

Three things that
save the evening.

Written on site, not on a laptop

The whole document is built on the phone, with no signal and no account, so the invoice goes out the day the job finishes.

Square-metre rates you set once

Skim, board-and-skim and render each with their own m² rate. Type the area and the line fills itself.

Tax worked out per line

Per-line tax and discounts, and reports that tell you what you owe by period without a spreadsheet.

03 · Questions

Asked by plasterers.

Can I write the invoice on my phone on site?

That is what it is for. Pick the client, tap your rates, send the PDF, with no signal if that is what the site has.

Can I price by the square metre?

Yes. Every price-book line carries its own unit, so m² and hourly labour sit on the same invoice.

What does it cost?

Nothing, up to a hundred invoices a year, with estimates, clients, all nine templates and every report uncapped.
