Reference: Heinen Delft Blue – Classroom Field Service Training
For the iconic brand Heinen Delfts Blauw, I trained the Field Account Manager during an intensive classroom sales training course . In the world of luxury retail and international trade, it's essential not just to sell a product but to take full control of the customer's purchasing process.
During this session, we applied the 12 sales techniques to the specific challenges of field sales. We delved deeply into the 11 scientific topics , focusing on lead filtering and converting "goodwill" into a technically advanced sales process.
The result for Heinen Delfts Blauw is an account manager who approaches the market with greater authority and structure. By applying the Graham Hulsebos Method, sales at this wonderful Dutch brand are no longer a coincidence, but a predictable system for growth.
