TDL for Tally

I require a Tally Addon for Creating 3rd Unit working in both sales and purchase and customised Invoice according to it with 3rd unit field, batch no. field, mfg date field & expiry date field all in separate fields. Also it gives me a button on gateway of tally to check balance of a ledger immediately, to check stock item immediately and auto emailer to send invoice as they are created and email ledgers by click of a button. Also a button to auto whatsapp invoice, receipt, ledgers in pdf format on designated whatsapp no.
