Job Cards for Tradespeople: From Quote to Sign-Off

What a job card is, what goes on it and how it keeps the work between an accepted quote and the invoice organised, signed off and billed.

The quote is accepted. Now the real work starts, and so does the admin nobody talks about. You have to find a day that suits the client, tell whoever is doing the job what was agreed, remember the extra bits the client mentioned on the phone, and at the end, prove the work was done before you send the bill.

In most small trade businesses, all of that lives in WhatsApp chats, a diary and somebody's memory. A job card brings it together in one place. This guide explains what a job card is, what should go on it, and how it saves time, arguments and unbilled work between the accepted quote and the invoice.

What is a job card?

A job card is the working record of a single job. Where the quote says what you will do and for how much, the job card tracks how it actually gets done: when, by whom, what was finished, what changed on the day and whether the client was happy at the end.

Paper job cards have been around for decades in workshops and on building sites. A digital job card does the same job but lives on your phone, so the whole team sees the same version, photos attach to it straight from the camera, and nothing gets lost under the seat of the van.

What to put on a job card

A useful job card answers every question someone might ask about the job, without phoning the office.

• The client, their phone number and the site address.
• The date and time of the booking, and how long it should take.
• Who is doing the job.
• The tasks to complete, ideally copied straight from the accepted quote.
• Notes for the team, such as access codes, parking or a dog in the yard.
• Photos from before, during and after the work.
• Any extra work agreed on site, with the price.
• The client's sign-off when the job is done.

If the job came from a quote, start the card from the quote rather than typing it again. The line items become your task list, the client details and address carry across, and the person on site works from exactly what the client agreed to.

Scheduling and briefing the team

Once a job has a date, put it on a shared calendar. A calendar view shows at a glance who is busy, who is free and where the gaps are, which makes it far easier to slot in a call-out without double-booking someone.

When you assign the job, the person doing it should get the card with everything on it, not a voice note and a pin on a map. That matters most for builders, where a single project can involve several people and visits over weeks. See how quotes and invoices for builders link the quote, the work and the final bill.

Send the client the booking too, and ask them to confirm it. A confirmed booking means fewer wasted trips to a locked gate and an empty house.

On site: the checklist and the photos

On the day, the job card becomes a checklist. Tick off each task as it is done, so anyone looking at the card can see progress without asking. Take photos before you start, as the work goes in and when it is finished.

Photos are cheap insurance. They show the condition of the site before you touched it, they record work that ends up hidden behind walls or under floors, and they give the client proof of a job well done. If a question comes up months later, the answer is already on the card.

Keep internal notes on the card too, separate from anything the client sees. A note such as "Geyser isolator is behind the washing machine" or "Client prefers a call, not a message" saves the next person on that site from finding out the hard way, and builds a history of every property you work on.

Handling extra work without losing money

Almost every job grows a little. The client asks for an extra plug point, you find a corroded valve that needs replacing, or the wall behind the old units is worse than expected. This is where small businesses quietly lose money, because extra work agreed in a hurry often never makes it onto the invoice.

Record every addition on the job card as it happens, with a description and a price, and get the client to approve it before you do the work. A quick approval on their phone is enough. Our guide on handling variations and change orders goes deeper on pricing and wording, and the same principle applies to every trade in quoting for construction and building trades.

Client sign-off before the invoice

When the work is done, ask the client to sign off. A typed name and a signature on their phone confirms that they accept the work as complete. It takes the client thirty seconds and gives you a clear record that the job was finished to their satisfaction.

Sign-off also makes the invoice easier to pay. A client who has just confirmed the job is done, with the photos and the approved extras in front of them, has no reason to dispute the bill. Send the invoice straight away, while the job is fresh, and include every approved extra so nothing is forgotten.

How QuoteGenio handles job cards

In QuoteGenio, one tap turns an accepted quote into a job, with the client, address and line items copied into a checklist. Schedule it on the jobs calendar, assign it to your team and send the client a booking to confirm. On site, tick off tasks, add photos and record extra work the client approves from a link, then get their signature on their phone. Finish by creating the invoice in one tap, with the approved extras already on it. See how job cards with client sign-off work from quote to invoice.
