In a busy workshop, the job card is the single source of truth about a car. When it is missing or incomplete, you get disputes over the bill, parts that never get charged, and mechanics arguing about who did what. Choosing the right workshop job card software, or even a better paper card, fixes most of that.
What is a job card, and why does it matter?
A job card follows one vehicle from the moment it arrives until it leaves. It answers four questions anyone in the workshop should be able to answer in seconds:
- What did the customer ask for?
- What has been done, and by whom?
- What parts were used?
- When will it be ready, and how much will it cost?
If your team cannot answer these without walking to the bay and asking, the system is not working.
What should every job card record?
At arrival
- Plate number, make and model
- Customer’s name and phone
- Odometer reading and fuel level
- The customer’s complaints, in their own words (“noise from front left when braking”)
- A walk-around checklist: scratches, dents, lights, tyres, spare wheel, items left in the car
- Bay and promised time
During the work
- Parts used, with quantity and the rack they came from
- Labour lines, each with the mechanic’s name
- Findings that need the customer’s approval (“brake pads at 2 mm, recommend change”)
Before delivery
- Estimate given, approved or declined
- Final parts and labour
- Who checked the work
The walk-around checklist is the one most workshops skip and later regret. It protects you when a customer says a scratch “was not there before”.
How should estimates and approvals work?
Most billing disputes in workshops come from work done without clear approval. A simple rule prevents them:
- Inspect, then give a written estimate of parts and labour.
- Record whether the customer approved or declined it, and how (in person, by phone or by message).
- If the work grows or the amount changes, ask again before continuing.
- Print the final bill from the same job card, so the numbers match.
Customers do not mind paying for work they agreed to. They mind surprises.
How do you track jobs across bays?
A job board shows every vehicle in the workshop by status:
| Status | Meaning |
|---|---|
| Open | Car has arrived, job card started |
| In progress | Mechanic is working on it |
| Ready | Work done, waiting for the customer |
| Done today | Billed and delivered |
At a glance, the owner sees which bays are busy, which cars are waiting for parts, and which customers should be called to collect. A whiteboard can do this for a small workshop; software keeps it in step with the job cards automatically.
How should parts and labour turn into a bill?
The biggest money leak in workshops is parts that were fitted but never billed. It happens when the job card and the bill are separate pieces of paper.
A good system:
- takes parts from stock when they are added to the job;
- carries every part and labour line into the bill without retyping;
- keeps the mechanic’s name on each labour line;
- marks the job as delivered when the bill is saved.
If you still bill by hand, at least staple the job card to your copy of the bill and check them against each other at day close.
How should you handle parts the customer brings?
Some customers buy their own parts from the market and ask you only to fit them. Note this on the job card as “customer’s part”, with the part name and condition, and bill only the labour. If the part fails, the card shows it was not supplied by your workshop. Many workshops also print a line on the estimate saying parts supplied by the customer carry no warranty from the workshop.
How do you pay mechanic commission fairly?
Commission on labour is common and motivating, but only if it is clear. Record each labour line against the mechanic who did it. At the end of the week or month, total the labour by mechanic and apply the agreed percentage. When the figures come straight from job cards, there is little to argue about.
What should you look for in workshop job card software?
Use this checklist when you compare options:
- Start a job from the plate number in a few keystrokes
- Records odometer, fuel, complaints and a walk-around checklist
- Parts linked to stock, with rack locations
- Labour lines per mechanic
- Estimate status: given, approved, declined
- Printed job card for the workshop and printed estimate for the customer
- A board showing every job’s status
- One step from job card to bill
- Mechanic commission and a labour-by-mechanic report
- The vehicle’s full service history, so you see what was done last time
- Works when the internet or power is down (with a UPS)
- Your staff can learn it in an afternoon
The last point matters more than any feature. A system your team does not fill in is worse than paper.
How do you get mechanics to actually use it?
- Keep it short at arrival. Plate, km, complaints, checklist. Details can be added later.
- Put a screen near the bays, or print the job card for the mechanic.
- Make the job card the only way to get parts. No card, no part from the store.
- Pay commission only from job cards. This motivates complete entries quickly.
- Review the board every morning with the team for five minutes.
How does service history help you sell better?
Every job card you keep becomes part of the vehicle’s history. After a few months, that history is valuable:
- When a regular arrives, you can see what was done last time and what was recommended but declined.
- You can remind the customer about the brake pads you flagged at the last visit.
- You can spot repeat faults that point to a deeper problem, or to a weak part from one supplier.
- You can show a customer selling their car a full record of the work your workshop did.
Customers trust a workshop that remembers their car. Make it a habit to look at the history before quoting.
What should the printed job card and estimate show?
Print two different papers. The job card is for the workshop: plate, complaints, checklist, parts with rack locations, mechanic and promised time. It goes on the car or the bay board. The estimate is for the customer: parts and labour with prices, the total, and a line for approval. Keep the estimate free of internal notes. Mixing the two papers is how customers end up seeing your purchase prices.
How does RMS handle job cards?
RMS has workshop job cards built in. On the job board, press N and type the plate to start a job: odometer, fuel, the customer’s complaints, the walk-around checklist, parts, labour per mechanic, bay and promised time. The estimate can be marked given, approved or declined, and if an approved estimate’s amount changes it goes back to waiting for approval. You can print the job card (with rack locations) for the workshop and the estimate for the customer, and Ctrl+I turns the job into a bill at the counter; saving the bill marks the job delivered. The owner sets mechanic commission on labour. See job cards and the auto workshop page.
