The QB email invoice function is not attaching the correct customised PDF invoice template - can anyone help?

Hello Steven38, 

Welcome to the Community page, 

Have you made sure that on the invoice you have selected the right template first before trying to print/preview it. 

So if you open the invoice up>at the bottom in the black bar you will see a word called customise >click that select the correct template then click on print/preview it should then show the correct layout for you.
