Oof, if a $900,000 invoice doesn't trigger review from their accounting dept, kind of their fault for not having a process of the common sense to question that bill.
I hate to say it but a lot of "accounting depts" these days are someone with no formal training who just took on the role as another hat on top of other hats as the more experienced folks retired or moved on to greener pastures. There's a shortage of accounting folks in general as well.
Amusing anecdote. My girlfriend has an accounting degree in the Ozarks and has had trouble getting work related to it.
There are many job postings for folks with 3+ years of experience. Very little is being offered for people who don't want to work in Big 4 or haven't completed a few internships. Most traditional entry level work is being or has been automated. Accounts receivable and payable are being rolled up along with payroll into the job duties of outsourced accounting and the like.
Oh they have more technology than thinking people in many non-technical departments. Automate the decision process and forget the edge cases seems to be the modus operandi.
The article just says it was a "cyber fraud incident" which is pretty vague. It may not have been a bill at all.
Going to go out on a limb and guess it wasn’t one invoice.
