The last part of a job is the money and the paperwork: an invoice with parts, labour and warranty, the deposit used up, the car handed back, and a history you can look up when the car returns.

## Before you start

- The job is **Ready for pickup** ([step 4](https://docs.smartposhub.com/business-types/auto-shop/step-4-run-job-cards/)).
- The cashier's role has **Convert job sheet to invoice** and a POS sale permission.

## Convert the job to an invoice

1. Open the job and choose **Actions › Convert to invoice**.
2. The POS opens with the customer, every part and labour line and any surcharge. Check quantities and prices.
3. Take payment: choose **Store credit (advance)** for the deposit, then cash or card for the rest. For a fleet account press **Credit Sale**.
4. Save. Parts are taken out of stock now, and the invoice prints the vehicle, VIN, faults and warranty if your invoice layout shows them.
5. Back on the job, click **Mark as delivered** and record who collected the car.

*Repair › Repair invoices: every invoice created from a job card, with repair and payment status.*

## Parts-only and walk-in sales

Customers who only buy parts or a quick service (wipers fitted, bulb replaced) don't need a job card. Sell them in **Sell › POS** like any shop sale; add a labour product if you fit the part.

## Warranty and comebacks

- Warranties chosen on parts print on the invoice; the job's warranty covers the work.
- When a car comes back, create a new job and tick **Warranty claim / re-repair (comeback)**. The **Comebacks** tab of the job list shows them, and **Repair › Reports** shows the re-repair rate per technician.
- If a part is faulty, return it on the original sale (**Sell › All sales › Actions › Sell Return**) and fit a new one on the comeback job.

## Vehicle history

- **Repair › Repair status lookup** searches job number, customer phone and name, alternate phone and VIN.
- The job list filters by status, technician, priority and date.
- The customer page shows every sale and payment, including repair invoices.

## Tips and mistakes to avoid

- Always convert from the job. A separate sale breaks the link between the car, its parts and its warranty.
- Don't leave delivered cars in **Ready for pickup**; the dashboard counts them as waiting.

## Frequently asked questions

### How do I bill a finished job?

Open the job and choose Actions › Convert to invoice. The POS opens with the customer, the parts and labour and any surcharge already in the cart. Take payment and save.

### How is the deposit used?

In the payment window choose Store credit (advance) for the deposit amount and take the rest in cash, card or on account.

### Can a fleet customer pay at the end of the month?

Yes. Give them a pay term and credit limit, finish the converted invoice with Credit Sale, and collect later with Add payment.

### Where do I see all repair invoices?

Repair › Repair invoices lists every sale created from a job card with its repair status, payment status and balance due. They also appear in Sell › All sales.

### The car came back with the same problem. What do I do?

Book a new job card and tick Warranty claim / re-repair (comeback). It shows in the Comebacks tab and in the re-repair rate in reports. Charge 0 for covered work.

### How do I find a car's previous jobs?

Use Repair › Repair status lookup with the job number, customer phone or name, or the VIN, or filter the job sheet list by customer.
