If you’ve ever listed something and then checked it two weeks later like, “Why do I have views and watchers but no sale?” this video is for you. I break down why that frustration usually comes from unrealistic expectations around how long items actually take to sell on eBay, Poshmark, and Depop. The biggest thing most resellers aren’t thinking about is cash flow—when you spend $5 on an item, that $5 is tied up until the item sells. It’s not “available money” for more inventory, supplies, or paying yourself until it turns back into cash. Then I walk you through how I use sell-through rate (STR) to set realistic timelines. I’m mainly using eBay comps, and I’m looking at the 90-day STR that eBay shows: number sold divided by number available. If something is around a 100% STR within 90 days, you still shouldn’t expect it to sell tomorrow—you should expect roughly a 3-month window. At 50% STR, I’m thinking closer to 6 months, and at 25% STR you’re basically tying up cash for around 9 months. My goal is to sell within 90 days or less, and I generally don’t recommend buying brand-based items under 50% STR. This is the kind of “whiteboard math” that helps you plan your business, stop guessing, and stop expecting two-week sales on items the data says won’t move that fast.
