Refrens is a business management platform focused on Indian freelancers and small businesses, providing GST-compliant invoicing, accounting, expense management, and project management in a unified solution. Founded in Bangalore in 2018, Refrens has grown rapidly in the Indian market by addressing the specific needs of Indian businesses including GST billing, e-invoicing compliance, and Indian accounting standards.

The invoicing quality—professional templates with accurate GST compliance—has made Refrens popular with Indian designers, developers, consultants, and agencies serving both domestic and international clients. Accounting reports provide P&L, outstanding receivables, and tax summaries. Multi-currency support handles invoicing for foreign clients with Indian tax compliance for service exports. Refrens' understanding of Indian regulatory requirements—GST, TDS, PAN, and professional invoicing standards—makes it a more suitable choice for Indian businesses than generic international platforms.
