As my boss says. Lighting, Focus, and backgrounds. After that just take 100 photos and worst case stack the focus and fix anything in your photo editor. Honestly most the work comes from taking 100's of shots and then finding the best to edit and clean up.

Agree, the more the better, especially if you compose all of them well! But even if you don’t, just sheer luck may do it.
Yah product photography is alot easier than real life or in action photography. Once you know what works usually can re create amazing and consistent images. Also if use photoshop or lightroom you can just save preset edits to save alot of time.
