Extras are additional, flat-rate charges on a storage job, such as an access or administrative fee or a prepaid retow (see Retow).
These extra fees must be added to the invoice and saved before any payment is accepted. Pricing cannot be changed after payment is accepted.
To add “extra” fees to an invoice, they must be configured in pricing parameters of the storage pricing templates.
Go to: Configuration»Pricing setup»Pricing templates:
The new Extra should be visible from the Storage Extras list on the Vehicle pricing tab in Lot Management. The extra must be added to each individual pricing template and saved.
