Which should you choose?

BUSY Accounting: Desktop accounting and inventory software widely used by Indian SMEs for GST, MIS reports and multi-location stock.

Invoice Ninja: Open-source invoicing, quotes, time tracking and client portal; can be self-hosted.

The best way to decide is to run the same week of real work through both — most offer a free plan or trial — and compare how long tasks take, what your team prefers, and the total cost for your number of users including renewal pricing.
