Thanks for stopping by the QuickBooks Community, citruscreekplant.
Tracking inventory by-products is unavailable in QuickBooks mobile app. Instead, I suggest tracking your inventory through a web browser.
Here's an article for available reports that will help you see the product cost, the product on hand, and more: Use reports to see your sales and inventory status.
To give more information about managing inventory in QuickBooks Online, check out this article: Inventory management.
Feel free to visit this article to find answers to your other QBO mobile questions: QuickBooks Online Mobile app FAQ.
