Hi Courtney,
Once you are opted in to managed payments, you won’t need to send any further payment methods from Sixbit. Unless you also want to offer PayPal, which isn’t currently supported. Once a buyer pays, the Order will come in as Paid to Sixbit with a payment type of “Other”. The only part missing is eBay returning the payment processing fee for the transaction, but we’ve put in a request for this to be added. This will only affect you if you use Sixbit for Profit/Loss reports which would need to include that fee when calculating the true profit on a Sale.
