How to set Voucher Numbers in Tally

In Tally, voucher numbers are automatically set by default. They start from 1, 2 and so on.

In almost every business, voucher numbers are not used like 1, 2, 3 and so on. They are used with some words or are of greater digits such as 101 or A-101 or TAX-101 and so on.

So you need to change the configuration voucher numbers in Tally which are set by default. Changing default configuration of voucher numbers in Tally is easy and simple.

Follow the steps below one by one and you can easily change the voucher number configuration in Tally.

Changing Voucher Number Configuration in Tally

First of all from Gateway of Tally, go to Accounts Info.


From Accounts Info., go to Voucher Types as shown in the below picture.

Accounts InfoFrom Voucher Types, go to Alter, because we want to edit the setup or configuration of voucher numbers in Tally.

Remember one thing, Alter is the option in Tally for whatever you want to edit in it.

Voucher Types in Tally

After pressing Enter on Alter, you will see a list of Voucher Types. From that list select the voucher type in which you want to change the method of voucher numbering.

Please note that whatever the voucher type you select, the procedure is same for changing the method of voucher numbering Tally.

You will see a list like as show in the picture below.


In this post we are going to alter the Contra voucher type. As I said earlier, the procedure is same for all voucher types. You learn from one of them and you can apply that to every other voucher type.

As soon as you go to Contra, a Voucher Type Alteration Screen as shown in the picture below will come up.

I have boxed out the option of Method of Voucher Numbering.


Change it to Manual from Automatic and you can easily enter whatever you want to while entering the voucher.

But remember, you have only changed the Contra voucher type and you need to change this setting in every voucher type you want to use.

It will not take more than 5 seconds per voucher type once you understand the process.

This is how you change the default voucher numbering in Tally.

On an important note, there are many more options than just Manual when you change the method of voucher numbering in Tally.

At the end…

If you find any difficulty in changing the method of voucher numbering, simple comment down below and I’ll solve all your questions.

            Hi, Sidhik!

            There is currently by default no method to prevent numbers from changing without switiching to manual numbering system.
            If you switch to manual numbering system, make sure you don’t change the previous voucher numbers otherwise every other voucher number will change too.

            For what you are asking can be done a customized add-on which you have to get developed by someone who knows TDL – programming language for Tally.

      For that you need to enable the Audit and Compliance mode.

      It can enabled in the Company Alteration Menu by pressing ALT+F3 from Gateway of Tally.
      Then, you need to alter the company and enable security.

    Leder of Bank not showing the all enteriesn after changing voucher number alteration in Tally (Account Info>voucher Type>Alter) previous enteries or enteries done after voucher type alteration.

    • Rishit Shah says:

      Hi, Raj!

      You cannot alter the Voucher Type for Bank because there is not voucher type called Bank in Tally.
      You have to alter the contra, payment and receipt voucher types as they are mainly used for banking entries.

  5. Saroj Sharma says:

    I have made entries in tally. Later, at the end of a month i requested bank statement. While verifying that i saw some transactions missing not entered in tally.
    So when i tried to enter missing transaction from bank statement which was backdated, all voucher numbers changes.
    So how can i enter the transaction to its original date without affecting other voucher number??

    • Rishit Shah says:

      Hi, Saroj!

      When you enter the transactions of earlier dates the voucher numbers for the following vouchers changes automatically so that each voucher is numbered chronologically.

      This cannot be changed in Tally.

    we use auto numbering for payment vouchers. we would like to implement PDC accounting in TALLY. i understand that the voucher numbers get altered once the PDC is accounted on due date. please advise how to overcome this problem.

  8. Sandeep says:

    If I add a new back dated voucher in tally I am getting an error that the voucher number already exists. It is not automatically updating the voucher numbers. This is happening for all vouchers where purchase, journal or otherwise. Please help.

    • Rishit Shah says:

      Hi, Sandeep!

      You cannot add the same voucher number again in Tally. If you want to enter the same voucher number again, you have to enable duplicate voucher numbering in Voucher Types in Tally.

      Hi, Raj!

      While passing POS entry, press F12 for Configuration.

      There will be an option called Allow modification of rate field during POS invoicing. Set that to YES.

      Now, you will be able alter the rate column and hence the amount column can changed as per what you like.

      Hi, Farheen!

      I am assuming you want to change the Voucher numbers. You can easily do that as I have explained in the post.
      You can do that right now too and it doesn’t matter what date it is.

  13. Vinod says:

    Hello, When I try to make one back dated invoice in tally it is showing an error as “duplicate voucher number”. However there is no other voucher with the same number. I have checked in many ways but cannot find any other voucher with same number. How can I clear this error? Please guide. Thanks in advance.

    • Rishit Shah says:

      Hi, Vinod!

      You can remove this error by doing the following.

      From Gateway of Tally, go to Accounts Info.
      Then go to Voucher Types and then select Alter.

      Now, select the voucher in which you are seeing duplicate voucher number error.

      There is an option of Method of Voucher Numbering. In there, select Automatic (Manual Override) and Prevent Duplicates to No.

      Now, you will not see the error.

    • Rishit Shah says:

      Hi, CMji!

      You need to pass a Purchase Voucher in Tally and while passing the voucher, you need to select that purchase order number.
      So, it will be against the purchase order.

      The Purchase Voucher will be Accounting Invoice and not Item Invoice.

  14. Thilini says:

    Hi Rishit Shah,

    We’ve set up automatic numbering of invoices, however, there has been an error made while entering in one of the invoices and this has upset the chronological numbering of all the invoices for that month.

    Is it possible for me to change the order to manual and fix the dates and numbers and then change it back to automatic so that it continues in that form?

    Thank you.

    • Rishit Shah says:

      Hi, Thilini!

      Can I know what was the error? Because that way I can help you in a much better way.
      Also, if you are not using any addon then if you change the voucher numbers from manual to automatic, Tally will change the numbers on it own, so please do not do this.
