Can I move Quickbooks Point of Sale Desktop 18.0 Verion to Online so that I can connect Quickbooks to Shopify using Shopify OneSaas or is there any other option?

It's good to hear that you want to move your QuickBooks Desktop Point of Sale to QuickBooks Online version, @okcorralwww. I'll provide you the steps to achieve your goal.

Currently, QuickBooks Desktop Point of Sale only links to the desktop versions. To move the file, I'd suggest looking for a third-party app that can integrate with QBO. This way, you can use a cloud-based POS that can extend your account functionality. You can either go to the Apps menu or through the external QuickBooks App Center. I'll guide you on how. 

To find apps within QBO: 

1. Go to Apps from the left menu. 
2. Enter Point of Sale in the Search box.
3. Select the app to open its profile. View the other apps by selecting them. 
4. Choose the right app for your business. 
5. Click Get app now. 

Once done, you can now integrate Shopify to QBO. For the app center, let's go to this link: apps.intuit.com. Then, perform the last four steps I've provided above. 

 Also, you can turn on the inventory tracking feature in Account and Settings. That way, you can manually add the products in the program using the inventory lists and balances from their POS file. 

Let me also share this link that can guide you through the detailed steps in connecting your bank account to QBO and more information about integrating Shopify :

• Connect bank and credit card accounts to QuickBooks Online
• Categorize and match online bank transactions in QuickBooks Online
• QuickBooks & Shopify
