Garage Software: Job Cards, Parts and Getting Paid

The job card is the whole system. It starts as a complaint, becomes an estimate, gets approved by a customer who is not present, collects labour and parts as work proceeds, and ends as an invoice. Software that treats each of those as an unrelated document guarantees the three will disagree.

This guide covers the job card lifecycle, the parts problem, bay and mechanic capacity, and the service history that turns a one-off repair into a returning customer.

One job card from complaint to invoice

The customer describes a noise. You inspect and produce an estimate. They approve some items and decline others. Work starts, and halfway through you find something else that needs approval. Parts are issued. The vehicle is delivered and billed. All of that is one job card with a history, not five documents.

The approval step is the one most systems handle badly and the one that causes the most disputes. You want the approved amount recorded with a timestamp and how it was obtained, and any addition after that treated as a fresh approval. A garage that cannot show what was approved and when will lose the argument at delivery every time.

• Complaint, inspection, estimate, approval, work, delivery as one record
• Approval captured with time and method, not assumed
• Additional work after approval treated as a new approval
• Declined items retained on the card for the next visit
• Final invoice built from the card, not typed separately

Parts are the leak

Parts issued to a job must reduce stock and appear on the bill in the same action. When issuing and billing are separate steps, some parts get issued and never billed, and both your stock and your margin drift. Nobody notices until an annual count is short by an amount nobody can explain.

Ask about returns too, because they are common: a part fitted and then found faulty, or ordered and not used. Both need to go back into stock as a recorded movement rather than being quietly re-shelved.

• Parts issued to a job card reduce stock and bill in one action
• Returns to stock recorded as movements with a reason
• Purchase rate and selling rate both held for margin
• Parts ordered specially against a job tracked to arrival
• Consumables handled sensibly rather than counted individually

Bays and mechanics are your real capacity

Promising delivery by evening is a capacity calculation, and most garages make it by instinct. Software that shows which bays are occupied, which mechanics are assigned and what is queued turns that guess into an answer, which is the difference between a customer told the truth and one told what they wanted to hear.

You also want time recorded against jobs, at least roughly. Not for micromanagement - for knowing whether the labour you charged reflects the labour you spent, which is the only way to know if your rate card is right.

• Bay and mechanic allocation visible for the day
• Job status - waiting, in progress, awaiting parts, awaiting approval, ready
• Time against job captured at least at start and finish
• Promised delivery time recorded and compared to actual

Service history is what brings the vehicle back

A garage that knows this vehicle had its brake pads changed nine months ago at 42,000 km has a reason to contact the owner. One that does not is waiting for the phone to ring. Vehicle-wise history, keyed to the registration number, is what makes service reminders possible.

The reminder itself is straightforward once the history exists: due by date or by odometer, whichever comes first, producing a call list. This is the single highest-return feature in garage software and the one most often left switched off after installation.

• History by vehicle registration, across owners
• Odometer captured at every visit
• Service due by date or distance, whichever comes first
• Reminder list with a record of what was sent
• Previous declined work surfaced at the next visit

The shortlist checklist

Take this to any vendor, ours included. If a question cannot be answered with a straight demonstration rather than a promise, treat it as unanswered.

1. Create a job card, produce an estimate, approve part of it and add work later.
2. Check the approved amount and time are recorded, not just the final bill.
3. Issue a part to a job and confirm stock reduced and the bill updated together.
4. Return an unused part to stock and find the movement.
5. View the day's bay and mechanic allocation.
6. Look up a vehicle by registration and read its full history.
7. Generate a service-due list by date and by odometer.
8. Ask who can change a job card after the invoice is raised.
