How do returns work with coins?
If your automated loyalty program is set so that coins are rewarded from aggregated invoices (multiple invoices can be combined for coins). So if a client comes in and purchases 2 bags of dog food for $50 each and pays off the invoice, they will receive one coin for the $100 invoice. If they then come back and return one bag, the coin will be taken away and their current balance for rewards will be $50. Once they spend another $50 they will be rewarded another coin!
Non aggregated: reevaluates the invoice that the returned item was from, if a coin was given off of that amount then the coin is removed. Looks at the latest invoice that has that invoice item on it to evaluate whether or not a coin should be removed.
