 ### What does the status of my invoice mean?
 The status of an invoice can be:
-* **Draft**: Refers to the invoice for the current calendar month. The billing period has not yet finished, so the invoice is not finalized and is subject to change.
-* **Stopped**: Refers to invoices where the billing period (calendar month) has ended, but the invoice is not yet issued.
-* **Issued**: Refers to a final invoice awaiting payment. It has a unique number and is non-repudiable. The invoice charges for the resources consumed over the corresponding billing period.
-* **Paid**: Refers to a fully paid invoice. No further action is required.
-* **Incomplete**: Refers to invoices where the user has provided incorrect billing details or payment information, or elements of this information are missing. The user must update this information as soon as possible to avoid having their account deleted.
-* **Outdated**: Refers to invoices where there has been a change in billing information, for example, a discount has been applied, or the client has amended their billing details. An updated invoice will be issued soon.
-* **Voided**: Refers to invoices with an amount of €0 before any discounts are applied. No further action is required.

 ### How long do I have to pay my invoice before my resources get locked?
 After your invoice is issued, you have ten days to pay it. If you fail to settle your invoice within this period, your account will be suspended, and your resources will become inaccessible. You will have another ten days to pay your invoice before your resources are deleted.
