Create separate bins with individual bin rules for each of your product variations, such as colours, sizes etc. Isolate products which are at risk of cross-contamination, e.g. chemicals, foods and set minimum difference requirements to ensure that your stock is always in tip top condition.
Automate your pick bin replenishment and always have stock on your shelves! Also, fulfil your bulk orders from bulk stock locations rather than from your pick face stock shelves so that you don’t completely clear your shelves when a big order is dispatched.
