Your Delivery Time Starts Before the Product Is Even Ready

Most stores calculate delivery time as the days a shipment spends in transit from China to the customer. Before a product ever enters that route, it may still need to be manufactured, customized, packed, inspected, and cleared for dispatch. That time belongs to the delivery promise too.

What gets missed

If a factory takes 20 days to restock and the shipping route takes 10, promising delivery based on the 10 days alone creates a delay before the package even exists. The carrier hasn’t received the order yet, and the promise is already impossible to keep.

Turning lead time into a reorder point

Reorder point = average daily sales × total replenishment time + safety stock

Selling ten units a day with a thirty-day replenishment time and waiting until stock nears zero to reorder is a stockout on a schedule, not an accident.

Safety stock isn’t a fixed number

It needs to account for sales variance, factory reliability, seasonality, route time, and the impact of running out of that specific product. The less stable the chain, the more protection it needs.

What happens when a campaign scales

A stock level that covered thirty days at ten daily sales covers only fifteen once volume doubles. Lead time hasn’t changed. Coverage has been cut in half. The reorder math needs to be rerun every time volume shifts meaningfully.

Separate what’s ready from what’s still in production

A product already in stock and a product still being manufactured can’t carry the same promise on the site. If a customer is buying something that still needs to be made, that condition has to be visible before payment, not discovered afterward.

Where the tracking happens

At Flow Border, a dedicated account handles communication with the factory and tracks stock, inspection, and route status, cutting down the time spent, after a sale, trying to figure out where an order actually stalled.

Before publishing the next delivery estimate, it’s worth checking whether the product is ready, how long the factory takes to restock, when it gets inspected, when it enters the route, and what that route’s typical variance looks like. Delivery time is set on day one of the chain.

Keeping that full chain visible is exactly what a Flow Border dedicated account is built to do.
