Updated November 2026. An oil change customer is worth far more than one bill. The same car needs oil, a filter and often tyre work again and again for years. The shops that grow are the ones that remind customers before they drift to the shop down the road.
Quick answer. Record the car, its current kilometres and the next change due on every bill. Remind customers on WhatsApp a few days before the change is due, by kilometres or date, whichever comes first, and follow up once after it is overdue.
What to record on every oil change bill
- Customer name and phone number
- Car make, model and number plate
- Current kilometres
- Oil brand, grade and quantity
- Filter changed or not
- Next change due by kilometres and by date
A simple reminder routine
- Every morning, look at the list of cars due this week.
- Send a short WhatsApp reminder with the customer name, the car and your shop name.
- Offer a reason to come back, for example a free filter check or tyre pressure check.
- Call the overdue customers personally once a week.
- Thank every customer after the bill, so your number is saved on their phone.
Stock that matches your reminders
Reminders bring cars back, so the oil and filters must be on the shelf. Track cans and loose oil by the litre, keep separate counts for the shop and the godown, and set low stock alerts for the grades you sell most.
Frequently asked questions
How often should a car get an oil change in Pakistan?
Follow the oil maker’s and car maker’s interval. Many mineral oils are changed around every 3,000 to 5,000 km and many synthetic oils at longer intervals, but dusty roads and city traffic often mean changing sooner. Your shop should record the interval on every bill.
Should reminders go by kilometres or by date?
Both. Some customers drive a lot and reach the kilometres first, others drive little and reach the date first. Remind on whichever comes first.
When should I send the reminder?
A few days before the change is due. A second message after the due date catches the customers who forgot.
Is WhatsApp better than SMS?
For most Pakistani customers, yes. WhatsApp messages are read more often and can include your shop name and location.
Can software work out when each car is due?
Yes. The Oil & Tyre POS saves the car, its kilometres and the next change on every bill, estimates how far each car drives and lists who is due by km or date.
Let the app remind for you
