Thanks for taking the time to reply, but doing something outside of quickbooks isn't a great solution. Simply need QBO to allow for a black and white formatted invoice that is clear, easy to read, and also meets the needs of those individuals who are visually impaired (no color shading, etc). This isn't a big ask - simply need to do a few things like make white an acceptable background color and that would eliminate the shading issue. Ironically, invoicing is one of the most fundamental functions of any accounting system and should be case tested against scenarios such as visually impaired recipients and USPS mailing best practices. Thank you.
