Whenever you update your Carro subscription, you may see Usage Charges as part of the cost of your subscription in Shopify:
Shopify usage charges are charges associated with an app's 30-day billing cycle and represent charges for app usage events. For Carro users, these charges represent Carro's 5% fee taken from each sale that we power.
Origination of the order starts on the retailer's end, so Carro charges its 5% to the retailer (this can be reported as one charge or broken down into line items for bookkeeping). To clarify, the 5% is already accounted for in the supplier's cut. What this means is that initially, the retailer temporarily grosses an additional 5% from a transaction.
25% to Retailer
70% to Supplier
5% to Carro
100% of the sale
In this case, the retailer is left with 30% of the order after their CC is charged for the supplier's wholesale cost. At the end of the retailer's billing cycle, the retailer will be billed Carro's 5%. At this point, the retailer will net 25%, which was the original agreed-upon value.
