Software built for Professional Services
Clients, engagements, retainers, recurring invoices and collections — for CAs, lawyers, consultants, agencies and studios that bill for expertise.
Meera runs a CA practice
Retainers on autopilot
Meera's monthly retainers invoice themselves, one-off engagements are billed in minutes, WhatsApp reminders chase the dues, and her own books stay clean — receivables, ledgers and GST included.

See it in action
Retainers on autopilot
Set a recurring invoice once — it raises itself every month with the right GST, and reminders go out on WhatsApp.

Bill like a firm, not a freelancer
Firms that bill for expertise lose the most money to un-billed and late-billed work — retainers that slip a month, engagements invoiced late, dues chased informally.
Saathi360 puts billing on rails: recurring invoices raise themselves, one-off engagements go from quotation to GST invoice in minutes, WhatsApp reminders do the chasing, and every rupee lands in client ledgers and your P&L automatically.
