Why is there no Custom title option in Purchase Invoices?
Purchase invoices are purely for internal use so why is there a need to change the title?
I Completely Agree with @Joe91
Purchase Invoice is just a mean to record credit purchase of a inventory item into the system.
There is no need of custom Title on that.
Can you explain why it is enabled in Purchase Quote? So if we for example would rename it for restaurant to Food Items Quote - Food Items Order - Food Items Invoice. This would also be consistent with the Copy to function as well.
@eko Purchase Quotes are external documents. They can be titled Request For Quotation (RFQ), Work Estimate Request. etc.
