Voucher ledger
As with most financial ledgers you will be able to track all vouchers that have been sold, redeemed and refunded as well as summaries of an opening / closing balance, voucher revenues and voucher redemptions. You will then see the list below of when the vouchers were bought, sold and refunded within the date range.
The voucher ledger can be found by heading to Reports > under the header labelled Finance you will see the Voucher Ledger > once selected you will be taken to the voucher ledger page as seen in the photo.
A date range is shown in the top left corner which will allow you to filter the voucher ledger by a specific date or through a various number of dates.
