Top Poshmark sellers share their secrets to making thousands of dollars on the popular clothing app

"For a beginner on the app, start off with building your brand: color scheme, consistent photography, and a catchy brand name. You want to make your closet a memorable experience," Cynthia Mendoza told Business Insider.

Mendoza is a full-time teacher and part-time seller who has made almost $35,000 in sales on the app.

Top sellers say it's wise to take current trends into account and see what is selling well by checking the top-selling categories and the number of likes on different items.

"Pay attention to what buyers want," Kristin Bachman said. "You have all that information at your fingertips."

Bachmann initially started out selling her own clothing from her closet, but she now has her own boutique on the app. If customers respond well to a particular style of clothing or fabric, she stocks more of it.

"See what products have hundreds of likes," she said. "You can see what buyers are gravitating towards."

"Unfortunately, it doesn't matter what the item is worth to you, shoppers most often will not pay for the sentimental value," Hill said.

This means it's wise to work out how much similar items are selling for in advance.

Part of the success of Poshmark comes down to the fact that it offers a social shopping experience. Canon said she has a loyal community of customers — 75% of her sales come from repeat buyers, many of whom she has gotten to know on a personal level.

"Be a customer service queen (or king!)," Ivy Mattio, a part-time seller based in Chicago, told Business Insider.

"Be helpful and answer questions promptly in a kind and courteous way, and always help buyers with any problems that arise."

"The more listings you have for sale, the better your chances are to sell," Mattio said.

If you list items more frequently and re-share your closet, they will stay in the app's algorithms.

"It can be very chaotic," Bachman said.

Being organized is crucial if you have lots of orders and new inventory coming in. She advises sellers to keep good records so they can review previous sales whenever they need to.

Sharing other sellers' closets could help get the attention of more potential buyers.

"It's a favor for a favor," Amber Aaron, a mother and full-time entrepreneur, told Business Insider.

This means there is more room for negotiation, and you can lure customers in with price drops, Aaron said.

"It's not going to be easy," Canon told Business Insider.

If you want to make this into a full-time job, you need to put in the hours. Successful sellers say their days are made up with sending out packages, sourcing products, photographing and uploading new items to the app, responding to customers' messages, and building up their community.

"It requires the dedication of a job. This experience is truly one where you get out of it as much as you put into it," Aaron said.
