When a salesperson in the computer store asks a customer who is deliberating over a purchase, "Will that be cash or charge?" he has executed which stage of the selling process?

closing stage

Explanation:

When a salesperson in a store asks a customer who is deliberating over a purchase " will that be cash or charge" the sales person has executed the closing stage instead of the handling or followup stage and which is quite earlier at this stage of purchase for the buyer because the buyer is still deliberating the purchase and have not made up his/her mind yet on what to purchase.

The salesperson should be convincing the buyer at this stage to buy or make his/her mind on what to buy  instead of trying to close the deal that is not yet matured for closing.

not sure- but i guess?
