Question
How do I add a negative payment to the Vehicle's total price?
Answer
In order to add a certain discount to the customer's order, you will need to add a miscellaneous cost to it. You can do by going to: Vehicles > Parameters > Parameters > Miscellaneous Costs.
You can either amend one of the existing miscellaneous costs or create a brand new one. Just make sure that you choose the option for Negative payment to show yes.
You can fill the rest of the information based on your needs and then Save it.
The you need to go to one of your customer orders to see how this works. Vehicles > Customer Orders > Create:
Since we have chosen that this would be a Pre Vat cost, you need to double-click on the Pre-Tax Item:
You choose the Miscellaneous cost and then manually type the negative price.
Once you hit Accept, the price will be updated on the customer order as well. You should be able to see the negative payment there as well (against Pre-Tax Items). It will reduce the total price by the amount entered by you.
