Frequently asked questions
Does OP Software generate Form 3CD?
OP Software lays out the figures each Form 3CD clause needs, in nine views with Excel export. You review them and complete the form on the income-tax portal. It does not generate Form 3CB.
Can I import 26AS and AIS?
Yes. Import Form 26AS text files and AIS JSON files and OP Software compares them with the books to the rupee.
How do CAs handle many client firms?
One login can hold many companies. Quick search switches firm in a keystroke, and each firm has its own users, rights and financial year.
Is there a partner program for CAs?
Yes. CAs and accountants who bring firms to OP Software earn free months, and partner pricing is available on a call.
