Anvil Brand review for QuickBooks Online

AVOID! This APP is having connection issues and the development team has been unable to get it corrected since Christmas. It worked flawlessly until mid December and after a Shopify update...this app has not worked as originally installed this summer. They have been working on it for 3 weeks now, still no solution. AVOID until further notice....seriously. We are installing a different APP until they get this corrected. Anvil Brand
