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.

The problem

Sound familiar?

The everyday headaches Saathi360 makes disappear for Professional Services.

How it works for you

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.

  • Recurring invoices
  • GST & SAC on every bill
  • WhatsApp reminders

A firm with clean books

Client ledgers, receivables and your own P&L stay current without a separate accounting tool.

  • Per-client ledgers
  • Receivables & advances
  • P&L and GST reports
Why it matters

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.
