I want to know whether you have any software for checking data entry accuracy. If you have that, please send me the details about it with the price of software and with your contact info.
There is an application called Entrypoint i4 which provides data entry accuracy on all types of businesses. On the official website you have a DEMO section and various pages to find out about the available features offered within the program.
You can also request a trial using the following link: http://www.entrypoint-idc.com/trial.htm
Unfortunately, the price will be available upon contact. I believe the price is different from customer to customer due to type of business, needs, budget, etc.
