Understanding the Query
Can you mention the reason(s) for this query? Dinesh Divekar has hit the spot—'Your main challenge is the low strike ratio of the sales calls.'
Like Saikumar and Nathrao mentioned, relating/linking sales targets to conveyance allowance is not just 'not right' but also counter-productive. You are giving scope for new problems that you could find tougher to handle, including possibly revolt by the sales team, in the worst-case scenario.
Steps to Address the Situation
First and foremost, sit with the Sales Head and figure out the probable causes for this situation. Also, sit with the Sales team without the Sales Head's presence (this gives you the actual ground realities without any fear from the team).
Then collate the inputs you received and discuss with the Company/Division Head/CEO/MD. Only then can you begin to think of solutions.
While I know I am making assumptions here, my guess is that it's a very accurate assumption. If some work had gone into finding the causes for this situation, the 'relating/linking sales targets to conveyance allowance' wouldn't even have been considered as a possible solution at all.
Potential Causes
While one definite reason could be what Dinesh Divekar mentioned—poor/improper training—the other reasons could also be poor targeting of prospects, low motivation of the sales team (for whatever reasons), poor management style of the Sales Head, unreasonable sales targets, lopsided hiring of the sales team, etc. These are just possibilities. The real reason(s) is for you to figure out, and please be mentally prepared to discover that there could be multiple reasons.
If you have already done some groundwork, then it's better to mention the details here so that the members of this forum don't have to keep guessing each and every possibility.
And yes, please confirm the sector your company is in. Factors/reasons can vary widely between sectors.
