A new module will need to be added for this to be possible. The module will be for managing Customers, which can then be made available on the transaction page. This feature may be added but cannot promise when.

I do appreciate your prompt respond and the excellent work done in this project. Managing customers, I believe will be an important module to be added to this project. Please kindly look into it. Thanks

me am about to add new feature like out-going transaction when the store manager buys something he/she might need to record that too and substract that money spent on expenditure from the total amount gained.

Thx for the helpfull project well designed and developed mr. @amirsanni
