Why this setup works
The work surface handles listings and labels while a narrow rolling cart holds daily supplies. Inventory beyond daily use stays outside the primary work triangle.
Measurements to confirm
Reserve 60 inches of uninterrupted wall width. Measure the largest parcel used weekly and add six inches of handling room on each side. Check the cart route through doorways.
Known tradeoffs
This is a daily shipping station, not bulk inventory storage. High-volume sellers will outgrow the surface and should separate packing from computer work.
