## Common Pitfalls to Avoid

1. **Storing payment data outside India** (RBI violation)
2. **Ignoring vernacular languages** (misses 80% of market)
3. **Skipping UPI** (losing 60%+ of potential transactions)
4. **Not integrating WhatsApp** (missing primary communication channel)
5. **Assuming English-only** (tier 2/3 cities are vernacular)
6. **Overlooking compliance** (CERT-IN, RBI, TRAI penalties)
7. **Poor mobile experience** (slow loading, data-heavy)
8. **High transaction fees** (users will abandon cart)
