Hi, I have received information from Bold that their App linking Shopify to Quickbooks has issues with GST. They are not currently working on correcting it as their developers are busy on another project. Be aware that your transactions will have errors especially with GST.
We are QuickBooks integrators currently working on our own QuickBooks Shopify integration bridge.
We can be of assistance. Please feel free to send me your contact information or send me a direct message.
