Although our ideal method of auditing is gaining access to your online account, in the beginning you can send us at least 8-10 of your most recent invoices as a PDF file (within 15 days of the invoice date). Once our auditing department receives the files, you will get a call from one of our reps on our progress and how much we saved you so far. Keep in mind though, that we recover more money using our ideal method and it also saves you a lot of time from having to keep sending us invoices. This alternative is simply to prove to you the savings and is only temporary.
