Dear Sir,

I want to open small business like General Store, but I want to acquire software for the purpose where should I have to obtain from and how much cost will be required?

There are a number of sites on the following link offering software for free or that you can purchase that you can use for a small business.

Small Business Free Software - Google Search

If you have specific questions about your small business, I am sure that there are people on this site who could also help you with that.

As far as paid software goes, a lot of small businesses use Quickbooks for accounting (200USD to 400USD depending on the version). Microsoft Dynamics - Point Of Sale will provide the POS functionality you need at counter (671USD, doesn't include cost of hardware).
