The merchant needs to be able to partially refund incorrect orders before the settlement/batch. If an employee accidentally adds an item to the order, the current method is to void the transaction and do it again. This is not convenient for the business.
This feature is under review.
Partial refunds is important option...either for a particular item(s) or a tax refund when we accidentally charge Taxes for a "Tax-Free or Tax-Exempt" organizations.

Currently there is not an option to refund a credit card payment without deleting the order at the same time. This is a problem for a restaurant because the whole order has to be re-entered and fired to the kitchen.

Partial refunds need to be permitted. I manage a skin care salon and would like to partially refund a tip that was set too high by mistake, as clients tap on the" tip "screen without realizing the % they tap on will apply to the entire transaction, even on products. I do not want to rip off my clients: when I spot a mistake of that nature, I should be able to correct the mistake by issuing a partial refund from the terminal before my client even realizes she overtipped when she gets her cc statement..
