Paying an outstanding amount

An outstanding amount ends up on an invoice. How to find that invoice in the app or in your inbox, pay it and start parking again straight away.

Updated September 8, 2026

An outstanding amount is money you owe SimplePark that has not been paid yet. It does not stay on your account as a negative balance: we put it on an invoice, after which your credit is back at € 0.00. As long as that invoice is open, you cannot start a new parking session. You pay it in the app or through the button in the email you get about it.

Where you see the outstanding amount

A red alert about your open invoice appears on the map: "This invoice still needs to be paid." That alert is the button: tap it and the app opens the invoice. In your profile there is also a red Payment badge next to the Invoices menu item. Open the invoice and it shows Outstanding payment at the top, with the button Pay now.

How to pay

  1. Open the app and tap the alert on the map, or go to Profile › Invoices › Payments.
  2. Open the invoice carrying the Payment badge.
  3. Tap Pay now and complete the payment with your bank.
  4. Back in the app the invoice is paid and you can start a parking session again.

Prefer to work from your inbox: every email about an outstanding amount carries the button Pay outstanding amount. It takes you to the same payment.

How an outstanding amount arises

  • Negative credit. Your session cost more than your balance held. You then get an email that your balance is negative and that action is required: the amount goes onto an invoice and your credit is back at € 0.00.
  • The direct debit failed. The direct debit could not be executed; you get an email that the direct debit failed, with a button to pay after all. We make no second attempt; you pay yourself.
  • Reversed payment. You had a collected amount returned; you get an email that your payment has been reversed and that you must pay manually. See Direct debit reversed.
  • No valid mandate. If direct debit is on without a working mandate, an email follows that your direct debit mandate is missing and that action is required.

The invoice that settles a negative balance has two lines: the amount itself and € 0.29 in transaction costs.

What happens if you do not pay

As long as the invoice is open, your vehicles are blocked and you cannot park. Day 14 brings a formal notice of default with a second payment period, day 21 a second and final formal reminder, and day 30 a handover to a collection agency. From that point collection costs are added under the statutory scale, a minimum of € 40, plus statutory interest. With non-payment of more than 60 days after the last reminder, we may place your account and plate on our internal incident list; that last part comes from the privacy statement. See Account blocked by an outstanding amount.

Amount not right?

Open the invoice and look under Specifications at the lines it contains; the individual sessions are under Activities. If you cannot work it out, email [email protected] with the invoice reference. Disputing an outstanding amount does not postpone payment: pay it, and we correct it if there turns out to be an error.
