This is a non-accounting voucher and the entries made using it will not affect your accounts. That is, Tally.ERP does not post these entries to ledgers but stores them in a separate Memorandum Register.
Some uses for Memo Vouchers
Making suspense payments
For example, the company gives an employee cash to buy office supplies, the exact nature and cost of which are unknown. You could enter a voucher for the petty cash advance, a voucher to record the actual expenditure details when they are known, and another voucher to record the return of surplus cash. However, a simpler way is to enter a Memo voucher when the cash is advanced, and then turn it into a Payment voucher for the actual amount spent, when known.
Vouchers not verified at the time of entry
It sometimes happens that you do not understand the details of a voucher you are entering. Enter it as a Memo voucher and amend it when you get the details.
Items given on approval
You will normally only enter completed sales into the books. Suppose items are given “on approval”. You can track them with a Memo voucher and convert it into a proper Sales voucher, or delete the memo voucher, depending on the outcome.
View all memorandum vouchers through Display > Exception Reports > Memorandum Vouchers. View them from the Day Book as well.
You can alter and convert a Memo voucher into a regular voucher when you decide to bring the entry into your books. Use Scenarios to see the effect of Memo entries on reports and statements.
