Labor-intensive products typically are the first to slow down in the production process as they tend to take a longer time to produce (items that are cut/sewn).

Stock and raw material shortages for products can cause delays especially when a manufacturer is waiting on an incoming shipment or if there are any supply chain issues.

Orders with only a single item move through production much faster because they don’t get held up at the fulfillment station. Orders with multiple items may have to wait for other items to catch up before getting packaged which may cause additional delays.
