Numbers tells all. You are applying as a sales person and it matters if you write down the numbers you achieved from your former job. Highlight the quota you handled and the percentage it increased since you managed it. Moreover, the number of clients you generated and maintained and any numbers that will foretell what a good sales person you are and this should be seen on your resume. Don’t be afraid to show off all your achievements because you have to bear in mind that you’re selling yourself and nobody else. But, be sure to tell the real and not the reel numbers.
