What gets in your way — and how OP Software fixes it
Accounting software assumes you sell goods.
The Services business type turns stock off, and service items start with a blank quantity.
Clients pay late.
Receivables and interest show every client's dues; bills go out by e-mail or WhatsApp.
The CA needs everything at year-end.
Give your CA a login: GST checks, TDS details and the balance sheet are already there.
What you get
- Service items and a Service invoice design

- GSTR-1 and 3B checks against the portal
- Receivables with interest
