Hi there, christy1.

Thanks for reaching out here in the Community for support. I'd be glad to provide some info on line numbers in the purchase order form.

The line numbers can be found to the left of the product or service. If the numbers aren't appearing, I'd recommend clearing the cache in your internet browser. Sometimes the cache can become bogged down with older data, potentially causing viewing errors in QuickBooks Online. This article will walk you through this process, depending upon which browser you're using: https://quickbooks.intuit.com/community/Getting-Started/How-do-I-clear-my-browser-cache-and-temporar....

Let me know how things look after giving this a try. I'll keep an eye out for your reply.
