Many retail spare-parts businesses maintain two distinct inventory zones: the front-of-shop sales counter where fast-moving stock is kept for customer billing, and a secondary warehouse or back-room where bulk reserves sit in high racks. Without clear location tagging, staff waste time searching for parts or assuming items are out of stock when they exist in secondary racks.
Distinguish shop counter shelves from warehouse racks by adopting a clean naming rule:
Rather than merging all inventory into a single lump sum number, record exact quantities per shelf location. For instance, a part may have 10 units on counter shelf `R1L1B1` and 50 units in warehouse rack `WR1L1B1`.
Set a default **Primary Location** for POS checkout so billing automatically defaults to shop counter stock without altering secondary warehouse counts.
