To upload contacts from QuickBooks Online, you’ll need to use the QuickBooks Integration.*
Visit Account > Integrations and click "Connect to QuickBooks Online". Then, select "Import Contacts" to begin pulling your contacts.
Pro Tip: You may do this multiple times as you add contacts to QuickBooks Online and Goodshuffle Pro will not download the same contact twice.
*QuickBooks Online integration is $39/month (Paid Annually).
