Hello @gailfro ,
Not sure if that is what you need, it is not focused on expenses only, it goes both sales and expense transactions. The app is Business Payments, it provides integration between PayPal/Square/Stripe and QuickBooks, so if you do the expenses via one of those systems, Business Payments will be able to record all the transactions to your QuickBooks automatically according to the settings of the app (it will create Sales Receipt and Expense on QBO end).
