The customer link for invoicing allows GEM-CAR to know that the invoices for a specific customer will be often paid by the linked customer (e.g.: insurer, employer, parent, etc...).

Here are some situations where the customer link can be very useful:
  • The insurance company is paying the invoices for the customer
  • The employer is paying the invoices for their employees
  • A parent is paying the repairs for a son

{fa-warning} Warning:
  • When a linked customer is set. He will not automatically pay all the customer's invoices. GEM-CAR will ask you to decide who to charge for each invoice.
  • Even when the repair invoices are paid by the linked customer, they are always attached to a vehicle. therefore will only display in the history of the account of the vehicle's owner.


A customer that can be linked is a customer (or a company) that will often pay the repairs for another customer (eg.: Insurance company, employer, parent, etc...). Both customers must be created in GEM-CAR.

  • Next to the customer number, check the box:
