QB Issue Resolution:

I’m not sure what you are asking, the two forms are not interchangeable, an invoice posts by default to a/r, a sales receipt posts to (usually) undeposited funds

You control the look and feel of the two templates.  Bring up an invoice or  sales receipt, click the formatting tab, click customize data layout from there you control what is on screen, layout designer controls the print copy.  Basic customization button brings up a new screen and lower left is a link for how to port one layout across multiple template formats
