A friend of mine runs an online store, and recently he's been dealing with more orders than his small warehouse team can comfortably handle. During busy periods, packing and sorting packages takes longer than expected, which sometimes leads to delayed deliveries and unhappy customers. We've been discussing whether reorganizing the warehouse, improving inventory management, or introducing automated sorting equipment would make the biggest difference. For anyone working in e-commerce logistics, what changes have helped you speed up order fulfillment without significantly increasing operating costs?
