Is there a way to enter a job description without it showing a zero in the amount column?

I also can see how convenient this is for you and your business. 

Currently, this is the design configured in QBO. When you enter a job description, the zero amount will still show regardless. As we value your suggestions, I recommend sending your feedback to our Product Development Team. Here's how to send feedback: 

1. Click the Gear icon in the upper-right corner.
