For all transactions on Poshmark, after the buyer makes a purchase, Poshmark takes hold of the paid funds and holds them within an escrow account. It is only after the buyer marks the package as received OR 3 days after the package is marked as delivered that the funds are routed to the seller’s redeemable balance.
This is why all Item-Not-Described cases must be filed within 3 days after the package is marked as delivered (so that the earnings can be held from redemption until resolution).
After system or buyer acknowledgement of order receipt, proceeds will move automatically (net of Poshmark fees) to a seller's redeemable balance. All seller earning redemptions are done directly within the portal with no need for invoicing, by going to My Balance: https://poshmark.com/account/balance.
Sellers can redeem their earnings using one of the various payout methods (e.g., Paypal, Bank Direct Deposit, etc.). You are welcome to redeem as frequently or infrequently as you'd like. Redemption details can be found HERE.
Details on how to redeem via Venmo or PayPal can be found HERE.
