How can I put my sales skill into good use?

Hi guys, let me tell you a bit about myself. The main job that I'm currently running is an online store with my sister selling Cosmetic Products. In which I'm the one handling Social media ads, SEO & some web development stuff. I used to be a top salesperson at my previous company but decided to pursue the entrepreneur dream so I quit my job and started this company.

My question here is, if I'm good at sales how can I utilize my sales skill to drive more revenue to my online store which I've just started. I just felt like my skills are being wasted sitting behind the PC doing backend stuff. I meant sales as in face to face.

Any recommendations are welcomed.
