2. Tally Prime — Best for Complex Accounting

3. Zoho Books — Best for Service Businesses

Price: ₹2,499/month | Platform: Web + Mobile

Excellent cloud-based GST billing with strong invoicing features. No offline mode makes it risky for shops. Best for consultants, agencies, and service businesses with stable internet.

For complex accounting needs: Tally Prime — worth the cost if you need full statutory compliance.
