Thanks for your message. There are no custom fields of type “Upload Document” that you could use in the Order Summary page, I’m sorry.
The built-in function to upload documents, such as the driver license, an ID or anything else you would like to collect from your clients, is only available once the rental order has been confirmed. There’s a dedicated View (page) to upload documents, but this requires an order ID as well as a customer ID in order to work correctly. For this reason, it is not possible to have such fields in the Order Summary, I’m sorry. This was made for security reasons as well as for database requirements, so that the documents uploaded will be actually assigned to the customer rather than to the rental order itself. Of course the customer will be assigned to any of its rental orders and so it will be easy for you to check the documents that were uploaded.
We hope this helps!
