OTIF originated at Walmart in 2017 as a way to fine suppliers who showed up late or with the wrong quantities. Pallets on trucks to distribution centers. Miss 98% and you pay 3% of COGS.
Your 3PL borrowed the same metric for DTC fulfillment, but the definition varies between providers. Key variables: when the clock starts, which orders count, what “in-full” means. Same fulfillment, different definitions, different numbers.
Why It’s Tricky
A 95% OTIF could mean fast warehouse but slow carriers. Or slow warehouse masked by overnight shipping. Or 99% most days and 70% after promotions. The number alone doesn’t tell you where the problem is.
What to Do Instead
Break OTIF into stages: acknowledgment, processing, handoff, transit. Each stage has its own benchmarks and failure modes. Stage-level metrics catch problems days before OTIF drops.
