Adding valet items to completed orders

Valet storage items that are added after a customer's invoice date will be added to their next invoice. The storage fee for those items will be pro-rated for the un-billed period. They will also be billed for the upcoming month of the total number of items in storage.

So, for example:

• Customer stores 5 boxes on 1 JUN
• They get billed for storage of 5 boxes from 1JUN-30JUN.
• They add 5 boxes on 15 JUN.
• Next invoice is 1 JUL. This will include pro-rated storage fees for 5 boxes from 15-30JUN and another line item for 10 boxes from 1JUL-31JUL

In the situation where you manually adjust/create an invoice to include the additional item before the next invoice is generated (e.g. from the example above, before July 1st). The system would still generate an invoice to pro-rate the additional item on July 1st (If there is a user invoice date). Here's what you can do:

1. Mark the invoice as paid with manual payment: Add a manual payment with a note, indicating the settlement of the prorated charge.
2. Make a zero balance invoice: Add a negative charge equal to the outstanding amount and mark it as paid.

These will stop the system from generating additional invoices. It is not recommended to delete the invoice as it will result in the system generating additional invoices while accumulating the unpaid amount.
