It's incredibly greedy of Intuit to force their customers to buy "special" envelopes in order use their invoicing and accounting program.  Shouldn't quickbooks simply adjust their invoice templates to fit in with office supply standards and sizing--standards that have been around for decades?  One programmer could fix the issue.  But no!  Instead quickbooks forces thousands if not millions of customers to adjust their business practices, causing headaches, huge aggravations, and time delays.  It is beyond distasteful and super tacky.
