Total fulfillment time covers everything your 3PL controls: from the order landing in their system to the carrier scanning the package. It stops where transit begins, so it isolates warehouse performance from shipping speed.
Why Measure It Separately from Delivery
On-time delivery blends warehouse speed and carrier speed into one number. Total fulfillment time strips the carrier out. A slow warehouse can’t hide behind fast shipping, and a fast one doesn’t get blamed for a slow carrier. It’s the cleanest single measure of how fast your 3PL is actually moving.
How Brands See It
Measure it straight from order timestamps, placement to pickup. No 3PL report required. To localize a slowdown, break it into processing time (pick, pack, label) and carrier handoff time (ready to ship to first scan).
