Question
How to record an In Stock Vehicle as an Insurance Write Off?
Answer
If a vehicle in your stock has been written off for any reason you may want this removed from your stock records.
To do this you would need to create a customer order against the vehicles where the insurance company is the customer. What this will do is allow the system to show that the money is coming from them, and this will also allow the vehicles to be removed from the system.
This can be done in Vehicles > Customer Orders > Create, once you have searched the vehicle which needs writing off you should use the Insurance company in the Customer and Invoice to boxes and then invoice as required. This would be a similar process as invoicing a vehicle to a finance company. 
Enter the Value you are receiving and the sales details as desired.
If the vehicles need to be written off without VAT then you can use a type of sale that is set to exclude VAT or you could use an internal type of sale if this is preferred.
Excluding VAT will not display any VAT on the reports and will invoice the vehicles without any VAT on them.
Internal VAT will still post the VAT amounts but then they will not be sent in the VAT return as the submission is designed to exclude all internal postings.
Once you have received the money from the Insurance company you can Invoice the vehicle within Vehicles > Invoicing > Invoice this will change the vehicle status to Invoiced, and no longer as In Stock.
