in sales transactions cost of sales is missing how to fix this ?

Hello Hamse, QuickBooks Online displays the cost of sales when the item is set up correctly. Go to All apps > Sales and Get Paid > Products and Services, then verify that your item is linked to the correct expense account. After that, you can view the Transaction Journal for your sales entry to see how the cost flows through.

In case you're running the Profit and Loss report when tracking the cost of sales, please verify that you are using the accrual basis to ensure the expense matches the sales period and appears correctly on the report.

If your cost of sales is still missing after these checks, it's best to consult our live support team for a thorough investigation into your account setup.

I'll keep this thread open in case you have any updates or need anything else.
