Home Depot is a chain, so the backend is probably being handled from some R&D center somewhere. Your maneuvering area at the local home depot is probably pretty slim.

Back in the early 2000's I did consulting work with Home Depot's backend developers. Their office is the "store support center", which is in the NW suburbs of Atlanta. I remember the team as being very good, but surprisingly small.

I've worked with a vendor listing products in their IDM (Item Data Management) System. IIRC, it's from https://www.stibosystems.com/ . From a SMB vendor supplying one type of product it's frustrating to work with, with a lot of back and forth and workflows for verifying all manner of compliance with data quality, global regulations, and laws. From their internal perspective, it's probably the bee's knees, supporting a wide variety of taxonomies, considering the variety of products they sell & support, some rather dangerous and hazardous.

From looking over the shoulders of the staff, some aspects of the system that I've seen as a supplier are directly visible to them too.
