# Billing of a service rendered for the ESA — ESA view The process describes the communication between MSB and ESA on the billing of a service rendered for the ESA and, where applicable, the automated complaint case.

## Process information Wording of the consolidated version, profile ch. 4.5.1, pp. 77–78.
  1. ### Preconditions - The ESA has ordered a transmission of values via the use case „[Request and order placement of values by the ESA](/en/prozessdoku/202604/ESA/WiM-Teil2-anfrage-und-bestellung-von-werten-durch-den-esa)“.
  2. ### Results The ESA will pay the invoice for the MSB issued by the MSB.
  3. ### Further requirements - The case of an invoice of the MSB that has been complained about or turns out to be incorrect (the cancellation of the original invoice is carried out either without a prior complaint by the ESA or on the basis of a prior complaint by the ESA) forms part of the standard process and, apart from clarifications, must be handled fully automatically. In the event of a complaint, the so-called “all-or-nothing principle” applies, according to which an invoice is either accepted in full as correct or rejected in full. The processes to be handled in the event of a conflict as part of receivables management or the dunning procedure are not shown and are to be resolved bilaterally. - An invoice references the underlying order placement.
  4. ### Trigger - Costs for device parameterisation have been incurred or - the billing of the transmission of values is due. **Runs beforehand:** [Termination of the transmission of values to ESA by ESA](/en/prozessdoku/202604/ESA/WiM-Teil2-beendigung-der-uebermittlung-von-werten-an-esa-durch-esa), [Termination of the transmission of values to ESA by MSB](/en/prozessdoku/202604/ESA/WiM-Teil2-beendigung-der-uebermittlung-von-werten-an-esa-durch-msb), [Transmission of values from MSB to ESA](/en/prozessdoku/202604/ESA/WiM-Teil2-uebermittlung-von-werten-vom-msb-an-esa) — these processes name the one shown here in their result.
  5. ### First message **MSB** sends “Invoice for a service rendered for the ESA” (step 1). From here on, it is the turn of the party involved on this page.
  6. ### Objective The MSB has been informed that the ESA accepts the invoice.
## Other views of the process The same process through the eyes of the other parties involved: the same steps, each read from their point of view. - [View MSB](/en/prozessdoku/202604/MSB/WiM-Teil2-abrechnung-einer-fuer-den-esa-erbrachten-leistung) — MSB *The steps are the **possible** messages of this process, not a sequence — the source lists neither conditions nor alternatives. The small box on the step names the own view on the left: with **←** it receives, with **→** it sends. Collapsed steps run between other market partners.* The connector table lists no write call for these steps. Derived from the process flow: the process begins for the own role with their message, so the transaction is created. Applies to: [1](#schritt-1) The connector table lists no write call for these steps. Derived from the process flow: the own role was already involved in this process, so the transaction already exists. Applies to: [3](#schritt-3), [5](#schritt-5) For this market role there is no write catalog; the step therefore shows only the command of the write call, without address and without button.
