Every vape shop owner has opened a cupboard and found a box of e-liquid that expired 6 months ago. The average UK vape shop loses £1,000-£2,000 per year to expired stock. For chains with 3+ stores, that number climbs to £5,000-£10,000.
The root cause is simple: shops track purchase orders, not batch dates. A box of 10ml nic salt bought 8 months ago is still on the shelf because it's in the system as 'active inventory', but the product itself has passed its recommended use-by date.
The fix takes 5 minutes a day: record every new batch by receipt date, and review the age flag each morning. TrackElf does this automatically. When a batch crosses 60 days, it turns yellow. At 90 days, it turns orange. At 120 days, it's red and flagged for clearance.
