Bookkeeping › Cash Book & Petty Cash
What is a two-column versus three-column difference in one line?
BeginnerAnswer
A two-column cash book has cash and bank money columns only; a three-column cash book adds a discount memorandum column on each side for discounts allowed (receipts side) and discounts received (payments side). The extra columns speed the recording and posting of settlement discounts.
Real-world example A business offering prompt-payment discounts adds discount columns, making its cash book three-column.
