What Mechanic Manager does when you Save Invoice as a proforma: it commits spare parts (Committed up, Available down) and does not decrement on-hand stock. It also skips GST, receivables and journals. Saving a tax invoice moves stock and posts the sale. Mechanic Manager prints the proforma as a Pro-forma Invoice.
