We are developing accounting / book keeping software.
For this purpose we like to collect different data from multiple sources.
For example:
Import Export Data From Point of Sale Cash Register.
We will like to do so for following cash registers: Saphire & Ruby.
After you look through this, let us know what else you can do.
We may also consider other brand cash registers too (or other point of sale systems).
Provide complete detail about the programming language, time needed and amount.
Data can be exported in csv format or to mysql.
