Air Con Automotive review for QuickBooks Online

Ok so I thought Onesaas was going to be the answer to my problems. I sell products both online and over the counter. So my problem was tracking changing stock levels between shopify and my store. So I need an app to update stock levels between shopify and my accounting software. However Onesaas does not do this. At least not for Sageone. If I sell an item using sageone then Onesaas does not update shopify. I though initially it was me and the way i had it setup but I contacted support and they confirmed how useless Onesaas is.
