    1. Karthik,
      Please Actually I missed to upload supporting files folder on the forum
      Please download the zip file again from the above link and also read the post again carefully which I edited yesterday.
      First go through the default logo you can see default tally logo there
      after that create your own logo in .TTF folder using font creator 5.5 etc. then rename it with default tally logo and copy paste it where the original tally default logo was installed from the supporting files.

      If face any problem, please do revert back at the support forum

  11. Dear Sir,

    My Tally SN is 7xxxxxxxxx my problem is that how can i use tdl & tcp file of tally 9 into Tally ERP 9 release 3 as I have converted tcp file but not working whereas it is working fine in tally 9 becoz on loading it shows to solve this problem

    1. Hello Suresh,
      Thanks for contacting us.
      The TDL made prior to Release 3 of Tally.erp 9 may or may not work as TDL definition has been changed to enhance the functionality of the software.
      You have to modify the TCP TDL coding only than it will work. Please contact the person who developed your TDL file. It will require some minor changes and then it will work fine.

    I wish to inform you that, in the previous version of tally release 4.5, when a cash sales voucher was made, there is an option to include the buyer’s details like name etc. This name is visible in tally only until the voucher is printed. The details of the buyer is not saved in tally. Hence if the sales voucher made towards a particular party has to be checked, I have to check the entire set of the printed sales vouchers, which is tedious and time consuming.

    I wish to explain our requirement as below:

    It is not possible to create a ledger for every buyer paying cash on sales.

    Therefore I am preparing cash vouchers with buyers name and details.

    Certain parties are being provided credit on cash sales. In such events, it is tedious to search the entire set of cash vouchers to find the particular buyer.

    Therefore my suggestion is to allow save the buyers details in the cash vouchers, in order to help search the buyer’s name instantly on tally.

    As per my suggestion:

    Option for Columnar Register Alteration [for sales]. Here one more Option may be provided for Buyer’s Name.

    If this option can be made available, then the list of cash voucher will show an additional column with the name of the buyer against the cash sales voucher. The list of all cash sales voucher would appear in the detailed columnar. This option will help us save a lot of time. This is just a suggestion;

    Any other suitable layout is up to you.

    Appreciate if you can try and make a TDL for the same in tally, so that all of my other tally friends can also use it and save more times.

      In Item analysis, you can see that types of reports. However if you have a specific requirement, then better to send me the format of the report to assist you better
