To motivate the salespersons, you need to understand them well. To understand them well, you need to go along with them for the sales call. For the time being, stop all your work and go with them for the sales calls for a week or so. Thereafter, you should reserve one day per week for field visits.
Your field visits will help you in understanding the competencies required for selling. Your quality of recruitment will improve as you will know well what kind of manpower you require. Your field visits will also help in training.
Field visits will help you in understanding the language they speak or the phrases they use. This will bring you on equal footing with the salespersons, and you will be able to get close to them mentally.
Field visits will also help in designing the sales incentives.
