Here's a scenario every builder knows by heart. The truck shows up exactly when it was supposed to. Right on schedule, except half the order is missing.

Was that delivery "on time"? Technically, sure. But-was it useful to you? Not even close.

The disparity between "the truck showed up" and "my crew can actually work" is exactly what OTIF is built to catch.

OTIF = On Time, In Full. Both halves have to be true, or it doesn't count. Not "mostly on time." Not "in full, eventually." Both. Every time.

And if you build with trusses, this isn't a nice-to-know metric. It's the difference between a schedule that holds and a schedule that unravels.

"On Time, In Full" isn't corporate-speak. 

OTIF is two simple conditions that either work together as leverage for your schedule or work as the primary bottleneck.

• On Time: Arrives inside the delivery window you agreed to.
• In Full: Everything you ordered is on the truck.

If you miss either one, you've got a problem that each come with a different flavor.

For example: a complete truss package that shows up a day late stalls your crew. What's worse is when you don't even know about the delay until the end of the day, which is why proactive communication is key here.

Now, if that same truss package does happen to show up on time but is missing a pivotal piece? Same result. Framing stops either way.

OTIF doesn't care about excuses. It cares about the outcomes. The outcome you need is simple: the right materials, complete, ready when your crew is standing there ready to work.

What is OTIF and Why Do We Talk About It So Much?

A missed delivery is rarely just a missed delivery. It tends to snowball.

If you've been building for a while, you know how this goes. Materials don't show up as planned, and suddenly you're:

• Paying a crew that can't get anything done
• Rearranging framers, equipment, inspections, subs (whatever else was riding on that day)
• Shifting labor to another job on short notice
• Making calls to track down materials or pin down a new delivery time
• Watching everything scheduled after framing slide back too
• Explaining the delay, again, to a homeowner or stakeholder

Some of that cost is easy to point to. Extra equipment days, extra labor hours. Some of the cost actually gets burried and goes unnoticed, things like: lost momentum, extra coordination, a project that never quite catches back up.

That's why OTIF is worth paying attention to. It's a decent shorthand for a bigger question: can this supplier actually help you keep the job moving, or are they just another line item?

Trusses Don't leave much room for error

Regular material showing up late is a headache, but a truss delivery running late or incomplete? That tends to hurt more.

Trusses aren't just another bundle of lumber. These are engineered pieces, tied directly to your plans, your production schedule, your crew, and your equipment. If they're not ready when everyone else is, there's often no easy swap to another task. And if even one piece is missing, the structure just doesn't move forward. And that stall has a way of reaching past framing, into dry-in, mechanical work, inspections-yeah, the whole chain.

A truss delivery that actually works usually started well before the truck left the yard via clear and proactive communication, accurate design info, production that's actually coordinated, real quality checks, and a delivery date that was realistic to begin with. OTIF isn't really a delivery metric on its own; actually, it's more of a report card for everything that happened before the truck showed up.

Four questions worth asking your truss supplier

Price is the easy thing to compare. It's also not the most useful one. Here are a few better questions:

1. How do you actually define "on time"? A real delivery window means a lot more than a vague target date.
2. Do you track whether deliveries are complete, not just whether they arrived? A truck that shows up on time with half the order is still a problem.
3. How do you communicate if something's going to change? The earlier you hear about it, the more room you have to adjust your crew and sequencing.
4. What's the plan when something goes wrong? Nothing's ever perfect. What matters is whether there's an actual process for fixing it and keeping you in the loop.

These questions tend to reveal pretty quickly whether a supplier is just shipping product, or genuinely trying to help you keep momentum from one phase of the job to the next.

The lowest price isn't always the lowest cost (amen?)

It's natural to compare truss quotes by scrolling straight to the number at the bottom. Sure, it makes sense, but the price of the package and the cost of actually getting it framed aren't always the same thing.

A great quote can lose its shine fast if an unreliable delivery leaves your crew idle, stretches out equipment rental, or pushes back everyone scheduled behind framing. That doesn't mean the cheapest supplier is automatically the wrong call, but it does mean delivery reliability deserves a seat at the table, right alongside price, labor productivity, schedule risk, and however much time your team ends up spending managing the fallout.

Build with fewer surprises

You've already got enough to keep track of on a jobsite without wondering if today's delivery is going to show up the way it's supposed to.

No supplier can control every variable on a construction project. But a good one owns the commitments they make, tells you before you have to ask, and builds a process that's actually meant to deliver on time and in full. 

At Wilson Lumber, that's really the idea behind how we think about OTIF: helping builders protect their schedules and build faster. From truss design and manufacturing through delivery, the goal's pretty simple- make sure your team has what it needs, when it needs it, so the job keeps moving.
