Effect on Payment Lag
The lag between purchase date and the date at which payment is due is known as the terms lag. The lag between the due date and the date on which the buyer actually pays is termed the due lag, and the lag between the purchase and actual payment dates is the pay lag.
Thus
Pay lag = terms lag = due lag
State how you would expect the following events to affect each type of lag-

b. A recession causes customers to be short of cash.
c. The company changes its terms from net 10 to net 20.
