Chasing down a department head or yet another budget holder to sign off on a 50EUR invoice is a waste of time for all parties involved.
With Markit you can get all of your IT orders to be invoiced either weekly or monthly thus dramatically reducing the number invoices your company has to process in this category.
Invoice consolidation does not need to be all inclusive - you can well decide to consolidate or not by expense type (opex vs capex).
