Aging is a process of categorizing the accounts receivable by all customers into separate time. It tells you how long you've had an asset or how long a bill has gone unpaid.

Imagine that you sold a product to John and Kate. John will pay you in two installments and Kate at once.

The first thing you have to do in Bkper to Aging is:
​ 
 1) Create a Receivable Account.

2) Record the products/services you sold.

3) Then the payments at the dates you expect to receive.

4) Check if you received or not all the payments.
