The best vape shops maintain relationships with at least 3 suppliers per product category. This avoids single-supplier dependency and lets you compare prices. Track each supplier's lead time: most UK vape <a href="/wholesalers">wholesalers</a> deliver in 2-3 working days, but popular lines can have 5-7 day delays.
Set a reorder point for each SKU: when stock drops to 2 weeks of average sales, place a new order. TrackElf's low-stock alerts notify you when a SKU crosses its reorder point, so you never run out of a top seller.
Track supplier lead times in the system so you know when to expect a delivery and can follow up if it's late.
