An already-live JVZoo product is edited from Sellers → Sellers dashboard: find the row, click Edit, change the section, then Save my product.
This is the official JVZoo tutorial. Watch it once, then use the click path below. Simon Harries, co-owner, is the author of this how-to.
Find the product, then Edit
Open Sellers → Sellers dashboard. Products already set up list here. Scroll, or use the filter tags if those were set when the product was created. Click Edit.
Jump a section, then save
Scroll the long form or use the left-hand options to open a section. Make the change. Scroll back up and click Save my product. The walkthrough’s confirmation is that the changes were saved successfully.
Creating the product in the first place: how to set up your first product. If a control is missing or a save fails, write JVZoo support with a screenshot of the screen you are on.
