Presales means the activities before closing the deal.What is the future growth of SAP Pre-Sales i-e career wise?
Presales is definitely an exciting career and depending upon your background, you could choose between technical and non-technical presales. Another classification is Products or Services sales. Generally for product sales, experienced people having expert knowledge of the product tend to land into such careers. Services sales is a but different and product-specific knowledge is not required much.
I believe a person is a better judge of his/her capacity for such a role as in case of professional firms, its not only about going to firms and delivering presentations. Although this is where you might start, you have to be a part of the overall sales strategy, go-to-market strategy, budgeting, marketing campaigns etc. as in the end, it is about the revenue you have generated for the firm. It is definitly a promising and exciting career path for the RIGHT person.
SAP Presales is a good career path but doing presales is much more about knowing SAP, the product. You will have to understand the firm's business goals and how to best position the firm against its competitors. In the long run, you must be able to depict an insight into the overall market and how to capitalize upon the opportunities that exist.
Hope this helps.
