I’m not defending castore cause I don’t really care I’m not Miss Rangers 2020 but this is just to explain to everyone tweeting asking ‘why are they selling stock they don’t have’. Thread. https://twitter.com/hrmtaxiservice/status/1338863687059181568

Every e-commerce site runs off the same stock management principles, the website feeds directly from the warehouse stock levels. Seems like it would be simple for the website to be bang up to date in terms of what is in stock and what is not but it’s tremendously difficult

The warehouse team will pick and pack orders in batches, the batch remains ‘open’ until every order from that batch is pick packed then when this is complete, the batch is ‘closed’ and that’s when the stock levels are updated which feed through to the website

Warehouse teams usually pick per product so they select a group of orders all for the same thing as this makes it easier for pick pack so 200x orders for one T-shirt you bag 200 up and it means less chance of mistakes. People will say why not just pick batches of 5 at a single

Time and then the stock levels will be accurate but doing that is inefficient. So large batches are the way forward but this poses a problem, stock levels not accurate during busy periods which creates more online orders for something that’s out of stock. Have to select a happy

Medium batch size which means things still get done quickly but not too many orders for out of stock items come through. If they were picked in small batches nobody would ever get their order.

Anyway there’s the logical explanation that no one cares about but at least I’m using my degree for something x
