Why GST Compliance is Crucial for Modern Repair Businesses in India
Electronics service centers frequently face billing confusion because a single customer job involves two distinct taxable components:
- Physical Goods (Spare Parts): Replaced LCD screen, battery, or charging port (Taxed under specific HSN codes, typically 18% GST).
- Services (Repair Labor Charges): Technical diagnostic and chip-level soldering labor (Taxed under SAC code 998713 / 9987, typically 18% GST).
Attempting to create these split invoices manually on generic retail billing software leads to accounting discrepancies and GSTR-1 filing headaches.
---1. Automatic HSN & SAC Tax Splitting
With CRMSaathi Repair, when an invoice is generated from a completed job sheet:
