- Vehicle number and type
- Prices differ for a hatchback, a sedan, an SUV and a bike. Recording the number and type ties the bill to the vehicle and supports customer complaints later.
- Wash or detailing package name
- Basic foam wash, premium wash and full detailing include different steps. The package name helps customers see what they paid for.
- Add-on services
- Engine bay cleaning, odour treatment or headlamp restoration are priced extras. Show each one separately so discounts on the package do not hide them.
- Membership or prepaid wash balance
- Monthly plans and 10-wash cards are paid in advance. The bill should show the plan used and balance left, so tax on the advance is not charged again.
- Coating warranty details
- Ceramic and graphene coatings come with a warranty period. Printing the product and period on the invoice supports a claim if the coating fails.
- Retail products sold
- Shampoo, polish and microfibre cloths sold off the shelf are goods with their own HSN codes. List them separately from the services.
- Staff or bay number
- Busy studios run several wash bays. Recording the bay or washer on the bill helps trace complaints about scratches or missed areas to the right shift and improves quality checks.
