The WooCommerce QuickBooks plugin isn't released yet. Here's how to get it when it is.
Visit syncible.co.uk/woocommerce-quickbooks/ and leave your email (and your store URL if you like). There is nothing to download or connect yet.
The moment the QuickBooks plugin is released, we'll send you one email to say so.
Then, in your WordPress admin, go to Plugins → Add New, search for Syncible, install and activate. The setup screen walks you through the rest.
Syncible for WooCommerce and Xero is available now. See the WooCommerce to Xero setup guide.
