The Phases of a Winning Sales Call There are seven phases for the call with a prospect and eight for an existing customer. 1. Build rapport and identify the buyer’s style. 2. Share the agenda (get buy-in, seek input). 3. Clean up their issues (only with existing customers). 4. Deliver the power statement (three minutes maximum). 5. Ask probing questions (also known as discovery). 6. Sell. 7. Determine the fit and seek out objections.
