Poshmark is a fantastic 'level up' for teens who have outgrown just asking for stuff and want to start earning. It’s less chaotic than Depop and more organized than Facebook Marketplace, making it the sweet spot for a first foray into the resale economy.

That said, don't treat it like a simple store. It’s a social app. There are follows, likes, and live broadcasts. If you’re letting your kid on here, they’re engaging with a community of adults. Set the 'no DMs' rule early and keep the linked bank account under your supervision.
