Service Business
Generate professional service invoices, manage recurring billing, and track client payments easily.
Problems we understand
Project-based billing
Billing for hours or milestones — hard to track with simple billing software
TDS deduction
Which clients deduct TDS? How much? Tracking this is complicated
Professional invoice format
Service invoices need different fields — SAC codes, place of supply, TDS
How we solve them
Service items with SAC codes
Pre-configured SAC codes for common services. GST correct automatically.
TDS tracking
Mark clients who deduct TDS. Track TDS receivable separately.
Recurring billing
Monthly retainer clients? Set up recurring invoices — auto-generated on schedule.

TDS tracking records which clients deduct TDS and the expected receivable. Recurring invoices auto-generate for monthly retainer clients. WhatsApp sharing gets invoices to clients in seconds.
