We have multiple depts using the same stock and we have a very convoluted process to invoice internal stock which is totally open to user error. It would be useful to be able to 'transfer' stock to different departments as and when they need to take items, instead of having to invoice and credit. Also a number of departments have vans so it would be useful if transferring stock to a van for general use.
