ONE JOB14 Oak Street

Same bathroom. Three pieces of paper.

Exhaust fan and four downlights. The quote is the offer. The estimate is what you send when the ceiling is still closed. The invoice is what you send when the money is due. Start with those documents, then the category, then the first week of a trade.

DOCUMENTSThe documents

The documents

Quote, estimate, work order, invoice. Four different jobs. Name the paper before you send it.

The documents

Invoice vs quote

A quote is an offer. An invoice is a bill. Sending the wrong one is how jobs sit unpaid, or get argued after the work is done.

The price

Quote vs estimate

An estimate is a range with assumptions. A quote is a price for a defined scope. Clients hear whichever word is printed at the top.

How to write a quote for a job

A quote that gets accepted already looks like the job on paper: scope, exclusions, line items, a validity date, and a way to say yes.

The instruction

What is a work order

A work order is what the crew opens after the quote is accepted: scope, site, materials, and when to stop and vary — not a second copy of the price.

The bill

How to write an invoice

An invoice is the quote lines plus approved variations, a due date, and a way to pay. Write it from the job, not from memory on Sunday.

CATEGORYThe category

The category

What the software is for, how job costing works, and how to price a job without guessing the hours.

The category

What is field service software

The system that keeps a quote, work order, schedule, time and invoice on one job — not a stack of apps that never talk.

Read the guide
The margin

What is job costing

Labour, materials and other costs against the price, so you see the job's margin before the invoice goes out.

Read the guide
The framework

How to price a job

Hours, materials, markup. A worked example — then check the margin before you send the quote.

Read the guide
The arithmetic

Markup vs margin

Markup is what you add on cost to get a price. Margin is what is left after cost as a share of the price. Mixing them is how a quote looks healthy and the job does not.

Check the margin before you send it

A clean quote still loses money if the labour hours are a guess. Run the numbers first.
