Handling time is one of the most overlooked levers in Seller Central, and one of the most consequential. It is the promise you make about how quickly you will dispatch — and it directly affects both your Buy Box position and your account health. Most sellers set one default value across their entire catalogue and never think about it again. That is a mistake on both ends.
One default is wrong for a mixed catalogue
If you set a long default handling time to protect the items you order in, your fast-moving in-stock products look needlessly slow — and lose the Buy Box to competitors promising quicker dispatch. If you set a short default to win the Buy Box on your in-stock lines, you over-promise on the items that genuinely take longer to source, and rack up late-dispatch metrics that damage your account health.
Either way, a single value across a varied catalogue is wrong for most of it. The products that can ship same-day are being held back, and the products that cannot are setting you up to fail.
Product-level handling time fixes both ends
The answer is handling time set per product, matched to how you actually fulfil each one. In-stock lines get the short, competitive promise that wins the Buy Box. Made-to-order or supplier-shipped lines get a realistic promise you can reliably meet. Buy Box competitiveness and account health stop being a trade-off.
The barrier is the manual work — so automate it
Nobody sets handling time per product because doing it by hand across hundreds or thousands of SKUs is impractical. That is the only reason the default exists. Build the product-level values systematically and generate the Seller Central upload file, and the barrier disappears. We built our handling-time tool to do exactly that — turn an impractical manual job into a single upload.
