It's enterprise sales so every contract is assumed to be above $10k.
One $22k contract may a lot for the bonus basket of the person closing the sale, but it is not be much for the company as a whole compared to the 20 other contracts being negotiated and the 200 current enterprise customers, and it definitely means nothing for the product/marketing groups who won't see a dime.
That being said I absolutely agree that if a customer is willing to pay for something, it's a very clear indicator of interest and it should be investigated. Hope it is easy enough to add and it is useful for every other customer!
