Can I pass the transaction fee onto the customer?
When a payment using POLi is made, the transaction fee is calculated using the total amount that has been processed and is charged after the fact and totalled at the end of each calendar month. Additionally, no money passes through POLi at any time. Due to these two limitations, there is no built in way to pass the transaction fee onto the customer.
There should be no real need to pass the transaction fee on as POLi offers low and very competitive pricing.
