Course Description
Welcome to Poshmark Mastery, your complete guide to turning one of today’s fastest-growing resale platforms into a real, sustainable business.
Poshmark began as a fashion resale app—but it’s now one of the most trusted marketplaces for clothing, accessories, home goods, and more. Its community-driven model gives your listings visibility and engagement that other platforms simply can’t match. Millions of active buyers are already searching for great deals every month, which means the opportunity to stand out and profit has never been better.
What makes Poshmark especially powerful is its simplicity. The platform provides prepaid shipping labels, handles payments, and protects both buyers and sellers—so you can focus on what really matters: sourcing great products, creating high-converting listings, and growing your business.
In this course, you’ll learn exactly how to:
Set up and optimize your Poshmark account for success
Create SEO-friendly listings that actually get found and sell fast
Use the right shipping tools and supplies to save time and money
Leverage automation software to scale your store efficiently
Source free or low-cost inventory to maximize your profits
While platforms like eBay and Amazon are crowded and competitive, Poshmark still offers a wide-open lane for new sellers to succeed. The resale market is booming, and buyers are actively seeking pre-loved and discounted items—making now the perfect time to start.
Whether you want to earn a little extra income or turn Poshmark into a full-time business, this course gives you the roadmap to do it. You’ll learn the proven systems I’ve used and taught others to build profitable online stores from scratch.
You’re in the right place, and the timing couldn’t be better. Let’s dive in and turn your Poshmark hustle into a business that truly works for you.

Yes! I am not computer savvy and this is helping me to understand some of the functions and apps. However,I will be asking questions because I am not quite sure how to do some of the listings.

I liked that course was fast and to the point, not a lot of fluff. Everything mentioned was meaningful. I like that I learned some new information I didn't know was available, it gave me some new ideas for my business. Thank you so much Bryan for taking the time to put this lecture together. Well worth the time and money spent.

Loved this course! I knew nothing about Poshmark and have a Shopify shop that had no sales. I decided to try Poshmark, took this course, started yesterday with the basics and got my first sale this morning! Excellent info judging by my results so far!
By Rhonda Holt on 5/17/2019
The course was really good and showed a few ways to make sales that's not obvious and he gave some good ways to get items to sell and resources. He speaks a little fast, but it didn't bother me at all, it kept me listening.

This course is so impressive. Bryan really knows his stuff when it comes to Poshmark! I got so many great tips; I can’t wait to hop back on Poshmark tonight and put these to use. This course is so worth the money if you have any interest in making money on Poshmark!

Super basic, the subtitles are completely wrong, and there are some mistakes on shipping prices charged and USPS mailing info. My store made more $ than the instructors with about 3,000 followers in my first month, I was looking for information to take my store to the next level, that he didn’t supply. No discussion on styling pics, other than make them look good. Very little discussion on pricing other then to discuss likes. He discusses Bots at length but never addresses that your account could get banned by Poshmark for using them and how to get around that. Also never provides statistics like- using IG increased my sales by 47% etc. I was also interested in dropshipping on Poshmark but it’s never covered. I’m not sure if I will ask for a refund.

This course is designed for the beginner to Poshmark selling. This is not meant for anyone who has experience with their closet. I would have liked to have seen more information on how to keep a well-organized closet like you see some of the Poshmark Ambassadors have. I think it's important to go into detail about how the Seller ratings work, how you can get more information about becoming a Posh Ambassador or be listed as a Top Seller, how being an active seller may help, without having the use of bots.
By Stephanie Malette on 2/4/2018
What an excellent course! I like that it starts from square one for those who might not have even gotten their feet wet yet, but it also goes into great detail and gives tips and tricks for the more experienced seller. I have been on the search for new ideas for listing on Poshmark, and this course teaches tips that you don't typically find anywhere else, especially not all in one place. Even better is that there is a lot of information packed into a reasonable amount of time, so you're not sitting in front of the computer for hours trying to weed through information you don't need. Well done! Highly recommend!

A great beginner's guide to selling with Poshmark. Course is detailed to where I feel confident t begin selling and building a network soon. Also presents some of the advanced selling methods. Course is short enough to where you can get the vital information and begin selling immediately instead of spending additional time in the course.
By Lisa Hawkins on 6/20/2017
I have "Poshing" for several months now. The information you taught was new to me even though I have been on the app for awhile now. You are able to think outside the box and make this work with the best possible options. Thanks.
