Counting unlisted inventory as productive inventory before it is listed.

Ways to improve Facebook Marketplace restock planning
Track sell-through
Measure sold items against active listing count, not total inventory.
List inventory faster
Unlisted inventory cannot sell until it becomes an active listing.
Protect cash flow
Avoid tying up too much money in slow-moving items.
Source proven items
Buy more only after confirming profit, demand, and sell-through.
