I need someone who is well versed in TDL to fulfill following requirements: 1)Using TDL make a voucher entry system that would allow multiple voucher entries pertaining to different dates and ledgers from single screen. There can be separate screens for payment, receipt, purchase and sales vouchers. The required fields should be made available in the entry forms. 2)This voucher entry system should be installed in the licensed tally version. Support should be provided if there is any problem. Also the method of installing these TDL modules should be explained. Please feel free to ask if you have queries. Work should be delivered in time.
