What happens if I underpay or overpay a Sheepy invoice?

If the payment amount does not exactly match the invoice total, the invoice may be marked as invalid or incomplete. Overpayments may trigger an automatic refund option on the invoice page, provided the transaction is confirmed and the surplus amount is above the refund threshold. In cases of underpayment, the invoice will show how much remains unpaid, and you can submit a second transaction to complete the total. If you’re unsure how to proceed, contact the merchant directly to resolve the situation.
