Most commenters think of this as an honest/dishonest situation on behalf of the agency. A different approach (and the one I'm reading it as) is that 'Isaac' operates as a seller that likes to make 100k per customer or project in any given time.

Not committing to each project, or actually listening, when the customer complains Isaac makes a few adjustments and continues business as usual.

He only cares about that 100k in a few month's time for a project. So now that he got only half of it he probably thinks he did the client a favor.

EDIT: the product is a life-saver for servers, kudos to the developer(s)
