Dear Swanand Batule,
If you have no process shop, fabrication shop, or the like to make prototypes and limit your activities only to paperwork, the unit will not come under the purview of the Factories Act. On the other hand, if you have any manufacturing process as under Chapter 1, (k), for sure it will be considered a factory, and you have to act accordingly.
Regards,
Kesava Pillai.
