I'm not sure what you mean by "it is charging me on the backend", but here is the typical shipping flow:
1) Customer pays the shipping fee you set.
2) You pay the shipping company to ship the items.
Ideally the fee you charge is higher than your actual shipping fee, but you can play around with this (for example giving free shipping at a certain threshold makes sense because of the additional profit from higher product sales).
