Got a vendor central invitation, is it better than seller central?

Something to read before you sign: vendor central has chargebacks. If your shipments don't follow their prep, labelling or appointment rules, they take fines off your invoices, and they add up quietly. Ask for the vendor terms and look at the fill rate expectations too, if you can't fill POs reliably they stop sending them.

Depends what you value more: control or volume. Vendor Central means you're a wholesaler. Amazon buys your stock, sets the retail price and pays you on terms, usually a couple of months later. Less admin on your side, but you lose pricing control and Amazon can squeeze margins at the yearly negotiation or just stop ordering. Seller Central you keep the price, the customer data you get, and the cash comes in faster, but you do more of the work. Plenty of brands run both. If you're small and cash flow matters, I'd be careful about going vendor only.
