I'm looking for a way to apply a refund to a customer, without an extension. To adjust inventory would too would be a bonus.
Best solution I've found was OpenCart Forum, by creating a product called 'refund' and either adding it to the invoice or creating a new order with just the refund amount.
It would seem to be a nice solution but is there a way to hide products in OpenCart 2? Not assigning it to a group it is still visible from search.
Ideally OpenCart should have a refund or reversal option, to correct the sales total and inventory. Since for accounting you can't just delete the order, there still needs to be a record of it.
