This confusion seems to extend beyond the forums. I've seen several posts of users frustrated to learn this feature is not included in the "essentials" plan. I only learned about it after downgrading, because who would have thought such an essential feature would be omitted. Even the Quickbooks pricing comparison chart seems to hide this fact either entirely or through clever wording, which leads me to wonder if Quickbooks is aware that such a basic function should OF COURSE be included in any bookkeeping software at any price, and is trying to keep that information as buried as possible to bleed its users of another $30 per month. What bookkeeping software doesn't let you pin a receipt to an invoice? Ridiculous.
