# General Information on Invoicing

- Invoices for rental charges are sent exclusively to [billing@klarx.com](mailto:billing@klarx.com)
- Reminders, complaints and other clarification requests should be sent to [kreditoren@klarx.com](mailto:kreditoren@klarx.com)
- Only one rental order can and may be billed on an invoice (no combined invoices)
- A completed and signed return protocol must be available for each order as proof of service
- Documentation for services beyond the order (e.g. extended rental etc.) is mandatory for settlement
- Services must be invoiced no later than 14 days after the service period
- Invoice complaints will be forwarded electronically to the appropriate branch.
- If we receive a credit note from you, we will offset it against your outstanding invoices at the next payment run. The remaining amount will be transferred. You will find the offset invoice and credit note numbers in the payment reference.
