Is there an app that you can integrate with QBO to add product sizes to a product?

I understand the importance of tracking stock and sales of products with different sizes and variations, mark. I'm here to share insight about this. 

QuickBooks supports various third-party applications for any functionality you may need. However, we can't provide an app we can integrate with the program. I recommend browsing our Apps menu to find one that meets your business needs.

1. Go to the QBO App Store. Choose GLOBAL on the upper part beside the Sign-in button.
2. In the search bar, type the keyword of the process or transaction you need.
3. Browse the suggested apps that match your needs.

I'd also like to give you these articles for more guidance in changing the item type for a product or service:

• Group Your Products and Services Into Different Categories
