Can I integrate quickbooks with wix website, and what is the best connector app?

It's nice to see a new member here in the Community, @stoneycandlecomp.

Yes, you can connect Wix with QuickBooks Online. 

WiX helps you map different accounts for each payment. Map tax codes to those available in QuickBooks Online. Share when an order is made in Wix and create or update the sales invoice or receipt in QuickBooks Online.

I suggest visiting our QuickBooks App Center for an additional overview of the product and its pricing.

Furthermore, we're unable to advise you on what's the best app that fits your company preferences. However, you can see lists of similar connectors on the page.

Feel free to visit us anytime if you need additional assistance with your invoice, reports, and any transactions you need to achieve. I'm always here to back you up.

Not really.  Does it integrate?  Yes, but you won't get your sales tax in QB.  Example.  Your customer goes to your Wix business site, and buys something for $1.00.  Let's suppose the state sales tax is 5%.  So $0.05 should show in QB as tax collected.  It DOES NOT!  I've reached out to the connector app support team.  They are "aware" of the situation with no ETA.  You would with that two mega-multi-million dollar companys could get their APIs to talk to each other, you would be wrong.
