The document discusses the voucher tally (VTL), which is a record of all guest transactions at a hotel on a given day. It includes guest names, room numbers, items purchased, and totals. At the end of each day, the VTL is sent to accounting to track weekly and monthly sales. Advantages include seeing all guest information and daily sales in one place, while disadvantages include it being difficult to manage due to size and possibility of errors when manually entering and tallying transactions. The document also discusses the guest weekly bill, which itemizes transactions for individual guests and is presented at checkout for settlement.
