Appreciate the reply. We are not looking for a test drive or a 30 day trail of QBO. We currently use QBO. We are looking for a not production environment in which we can test transactions before we do them in the production data base.
Yes, there's a sand box for QBO. You can find it in the Intuit Developer Community. Hover your mouse over API Docs & Tools at the top right corner, highlight QuickBooks Online, and then choose Sandbox .
You'll be asked to sign in with your Intuit credentials. If you already have a QBO account, you can use the same login info. Otherwise, you'll need to create an Intuit account.
