You don't need software as product. There is a Scrum Team developing yoghurt. Their deliverables are yoghurt, a marketing plan, branding, market studies, ...
So, look at what your Product Backlog Items are, and see how your customer/user uses them. Then you'll know what the "deliverable product" is.
In this case, I imagine it's "screens", "pages" or "forms". And while those can maybe not be packaged in a zip file or checked in into source control, you will "hand them over" at a certain time. And not all PBI's need to be the same type.
