Sales representatives also learn to recognise specific verbal and non-verbal cues that potentially signal the prospect's readiness to buy. For instance, if a prospect begins to handle the merchandise, this may indicate a state of buyer interest. Clients also tend to employ different types of questions throughout the sales process. General questions such as, "Does it come in any other colours (or styles)? indicate only a moderate level of interest. However, when clients begin to ask specific questions, such as "Do you have this model in black?" then this indicates that the prospect is approaching readiness to buy. When the sales person believes that the prospective buyer is ready to make the purchase, a "trial close" might be used to test the waters. A trial close is simply any attempt to confirm the buyer's interest in finalising the sale. An example of a trial close, is "Would you be requiring our team to install the unit for you?" or "Would you be available to take delivery next Thursday?"
