As you have done B.Tech and is much more experienced as you have worked in the service sector, sales & service engineer and sales manager, so it will be quite easy for you to understand the online course.
Some online courses for sales are:
1. Online Sales and Marketing Management Courses of Credit-Study.com's. These courses offer an affordable and effectual path to college credit. They offer in-depth training through the engaging video lessons taught by marketing and sales professionals.
2. Free Online Non-Credited Sales and Marketing Management Courses-These free online courses don't require students to enrol or register, but they also don't typically award any college credit. Students may need to obtain special software, such as document readers or media players, in order to access course materials.
3. Kutztown University of Pennsylvania-Identifying Your Sales strategy which includes discussions on client needs, product/service differentiation, targeting and sales talent acquisition. A slide presentation with audio guides the student through sales forecasting, budgeting and presentation skills.
4. The Open University-It also provides online courses on Marketing Communications as a Strategic Function. The Market-Led Organisation and Social Marketing.
5. Sales Strategies: Mastering the Selling Process-This is a sales course created by University of Chicago.
