Rulee vs Vider ATOM
We make Rulee. Everything about Vider ATOM below comes from its own website as it read on 19 October 2026; "not stated" means its site did not say, not that the feature is missing. If anything is wrong, write to support@rulee.in and we will correct it.
The short answer
Choose Vider ATOM if pulling data and notices from the Income Tax, GST and MCA portals matters most (with ATOM Pro for income-tax e-proceedings and demands), or if you need a client portal and a UDIN register. Choose Rulee if you want published prices for the whole firm, GST invoicing that settles with TDS, each client's fee set against the hours worked, client GST reconciliation, letters and engagement letters, and no client documents kept by your software.
