Experience is a wonderful teacher, but only if you pay attention and draw the right lessons from your experience. It pays to document certain portions of your company’s sales process—and the most successful practices that you and your fellow salespeople have found for handling common challenges. Salespeople who do this maximize the use of their time, shorten sell cycles, make more sales, and cash bigger paychecks.

To learn from what works, document what works.

What parts of your sales process should you document?

First, identify the milestones in your sales cycle. What are the necessary steps that lead from your initial contact with a prospect to a completed sale? What commitment must you gain from the customer at each milestone that will lead to the next step? For example, does your sales cycle usually require an initial meeting with several decision makers followed by another meeting at which you present a formal proposal? Both of those meetings are milestones.

Write down your 10 strongest sales features—the features of your products or services that have the strongest appeal to most customers. Include a benefits statement for each feature. Remember that benefits usually have dollar signs attached.

Next, write down the expected customer needs associated with those 10 features and benefits. Customers will only buy if a benefit represents a solution to a perceived need. So what needs must you look for? Write some open-ended questions that help you draw out needs for which your 10 strongest features offer solutions.

Write the best questions that you can use to determine what your sales strategy must be for a particular client. Your sales strategy is determined by the competition you face, the buyer’s time frame, and the buying influences that will play a role in the sale. What are the best questions with which to draw out information about those factors?

Document a crisp (30-second) and powerful company story that you can tell in all first-call selling situations.

Ask your peers about each of these topics, and compare their approaches with yours. If somebody else has a great question for drawing out needs, for example, by all means write it down and use it. Create reminder lists for yourself, and review them before every sales call. Then you can stop making the same expensive mistakes.
