This email issue has been reported to QuickBooks by MANY customers and QuickBooks support refuses to do anything to correct this long-term issue.

IF you utilize Projects or client sub-accounts for your business, QuickBooks is NOT the software to use for your busyness as this long standing email issue prevents all your clients from receiving your companies invoices.

Wish I new this before I switched to QuickBooks as I would have chosen another accounting software company.

Spread this message until QuickBooks resolves this issue so other business do not make the same mistake we did.
