Even if you don’t plan to sell anything in a physical store, barcode. It means that you can track every item, and that you have an immediate view of stock levels. It’s a simple move that will put you in control of your inventory.
If you’re using Google Sheets or Excel, stop. Get a system that scans items, gets them on the shelves quickly and then has them ready to be bought again.
If you want to send out next day deliveries every day, they need to be reliable and your fulfilment processes need to be tight.
Then you’ll know whether you have to address the problem with your suppliers, or to advise consumers about garments that run small.
You need to have a tight control over stock levels in the warehouse to make sure that you’re not overpromising and underdelivering.
Keeping consumers’ attention, and giving them what they want in the instant that they want it, will be absolutely critical in 2018.
