I already paid the invoice. Why do I keep receiving payment reminders?

If you have paid an invoice online using a credit card, our system automatically registered the transaction, and you will not receive any reminders. For any related issue, please send us an email to accounting@frontiersin.org.

If you used a different payment option (such as bank transfer or check), there is a technical delay before the payment is deposited into our account. Also, it could take a few days for the accounting office to match your payment to your invoice. The verification time can be substantially reduced if your invoice number is clearly indicated in the transaction details, and if you upload a proof of payment (from the invoice detail page).
