I’m not sure yet TBH, but you’re welcome to help or build your own.
I intend to make it an entirely free and open source platform that allows retailers to broadcast their inventory to aggregators. No ads just like Lemmy, though I suppose that the feed itself serves as kind of an ad.
It was intend for the cannabis industry then my plan was to roll it out to the rest of the retail world when it is evolved enough.
There’s also veilid.
I even started a community here: https://infosec.pub/c/lemventory
At least in the cannabis industry here, they have a piece of software that they use to submit their inventories to the state. My current plan is to look into incorporating my system into that so I get accurate reports that are required by law to be done anyway.
I’d love to discuss further the pitfalls of my idea and any special considerations I might need to make.
