It is not the case of only IT companies, but almost all are maintaining the registers in soft form. However, there is one difference: IT firms maintain the registers in soft form as a matter of their right, while others follow this practice after obtaining due approval from the labor department. Certainly, you need not keep the registers in hard form, but you can have a computerized system for all your dealings with the employees, provided you take approval from the concerned person of the labor department after submitting a specimen of each register and returns which you generate through the system.
Under the Labor Acts, salary has the same meaning as wages, and all employees who do not possess any managerial rights come under the purview of these Acts. Therefore, just by saying that your company does not pay wages but pays only salaries, or you do not employ workers but only employ professionals, the labor laws will not become inapplicable to you. You have to establish that all are managers and there is nobody to work! At least to the extent of the employees engaged through a contractor (for the service of housekeeping, etc.), you will come under the Labor Acts!
There is nothing wrong with meeting the Labor Officer and discussing the matter in person. If you discuss the matter, it can be solved. However, you should be realistic and not show that nothing in the labor laws is applicable to you just because you employ some professionals only.
