GST Invoice Format for Auto Parts & Service Garages
Parts at 28%, labour at 18% — job-card billing that keeps both straight.
The motor trade lives with the top slab: most vehicle parts fall under HSN 8708 at 28%, tyres at 28%, while repair labour is a service at 18%. A garage invoice is naturally a mixed supply — the format must keep parts and labour as separate lines with separate rates, tied to the vehicle and job card.
What this invoice format must include
Parts and labour on separate lines
Parts at their goods rates (mostly 28%), repair labour under SAC 998714 at 18% — never a single blended line.
Vehicle identification
Registration number, odometer reading, and job-card number on the invoice — insurers and fleet customers require all three.
Correct part-level HSN
General parts 8708, tyres 4011, batteries 8507, lubricants 2710 — each with its own rate.
Warranty replacements
Free warranty parts move on delivery challans, not tax invoices — only billable work belongs on the invoice.
