Idk why it's taking Quickbooks so long to add this feature. Submitted a request for this feature back in 2018. All you'd have to do is add another field to the product info page and make it searchable on the invoice page like SKU's & Product Name are. Would literally take 10-15 minutes to make the code + database changes needed. But they'd rather keep these features "premium" to upsell you a completely different product. I don't want to use Quickbooks Desktop.
