Welcome to the Community, Sunshine. I have the steps for adding a PRODUCT/SERVICE column on sales receipts.
If you are on the Sales Receipt page and the PRODUCT/SERVICE column is not showing, I recommend opening your sales receipt using a private window to narrow down the issue. Unlike the regular browser, private windows don't store any history or form data. Over time, this could cause problems while working with QuickBooks.
To save you time, you can use either of these shortcut keys:
- Mozilla Firefox: press Ctrl + Shift + P
- Internet Explorer: press Ctrl + Shift + P
- Safari: press Command + Shift +N
If it works fine from there, switch back to your regular browser and clear its cache.
If the issue persists, try using other supported browsers to narrow down the cause.
However, I've provided steps below if you aren't on the Sales Receipt page. This customization will be used moving forward if you are going to set it as default.
Here's how:
- Go to the Gear icon and click Custom form styles.
- To create a new style, click on the New Styles dropdown and select it.
- In the Content tab, click the body of the sales form, then tick the Product/Service.
- Select Done.
The screenshot is attached for visual reference.
