The most expensive OASIS+ mistake I've seen: counting product revenue toward a services threshold.
A qualifying project shows over a million in average annual value. Looks comfortably above the requirement. Then you look closer, and three-quarters of that money was products, not services.
OASIS+ is a services vehicle. Only the services portion counts toward the $500K average annual value requirement. Strip the products out and that comfortable project drops under the line.
The root cause: firms read the dollar figure and assume they qualify, without reading how the dollar figure has to be built.
The qualification rules are where most self-prepared submissions quietly fail. Not the writing. The math underneath it.
