This is business process dysfunction, and I bet their AP/AR spend management software was setup wrong.

They can try to spin it as a free loan from you or the ROI gain of running a leaning team, but they're paying 400% more (150k v. 30k) in a current reporting period.

Nothing clever.

You're also sticking around and not getting burned out of repeat business. I like increasing prices to compensate and being upfront.
