In off-site manufacturing, change is inevitable. What is not inevitable is losing money because of it. The change order is not red tape. It is protection. It protects the company, the client, the project schedule, and even the salesperson who worked hard to land the job.
Consider how a typical project flows. The customer provides specifications. Sales reviews the plans. Takeoff is completed. Pricing is approved. Sales makes a presentation and wins the bid. Internal meetings are held. Design produces sealed truss drawings. Materials are confirmed. Production schedules the job. The project is rolling.
Then, it happens.
The job is almost to production, and the customer asks for a small change. Maybe it is a pitch adjustment. Maybe the gables are framed differently. Maybe a bearing point shifts. It sounds simple. The sales rep walks into design and says, “Can we just tweak this?”
Now the real questions begin. Do we have the correct lumber sizes and grades? Does it require new seals? Do the plates change? Does it disrupt the production schedule? Is engineering affected? If it costs more, who absorbs the cost?
Without a formal change order process, that “small change” can cost real money. Extra lumber. Different or additional plates. Lost labor time. Rework. Schedule disruption. And if pricing or estimating never sees it and costs change, there is no markup. The company eats it.
Worse, if the salesperson is compensated on profitability, that bonus can disappear because of an untracked favor.
Here is another common scenario. Design reviews the customer’s blueprints and determines that the trusses, as drawn, simply will not work in the shop or cannot be delivered as designed. They cannot be built as specified. Sales and design collaborate on a solution. Sales get the customer's approval. It goes to production. Everything runs smoothly.
Except the fix required five percent more lumber and ten percent more plate weight. Cost accounting catches it after the fact, too late.
If the change did not go through a formal change order process, nobody documented the added cost. Nobody secured approval. Nobody adjusted pricing. The job looks profitable on paper, but it quietly eroded margins.
I recently spoke with a plant manager who shared a real example. A builder requested what he called “a minor adjustment” to raise an interior ceiling height. Sales approved it verbally to keep the relationship smooth. Design reworked several trusses. Production had to set aside a portion of cut lumber, recut, and change plate sizes. The job shipped on time, but the plant absorbed additional material, labor, and engineering time. The total impact was just under four percent of the contract value. On a competitive bid, that was the entire projected profit.
No one intended to give away margin. It simply slipped through without a formal change order.
This is exactly why disciplined change order systems matter.
A proper change order process ensures every department is informed and signs off in sequence. Even if a department is not directly impacted, they have the opportunity to confirm that their scope is unchanged. Purchasing confirms material availability. Production evaluates labor and schedule implications. Engineering confirms structural integrity. Estimating verifies cost impact. Sales secures customer approval and upcharges when appropriate.
It is not about slowing down the job. It is about preventing runaway changes, poor communication, and well-intended giveaways that cost design, production, and materials that were never in the bid.
Yes, implementing and enforcing a change order policy can be uncomfortable at first. It requires discipline. It may feel rigid. But it establishes accountability. It clarifies where the additional cost belongs. It documents delays. It protects the margin.
Most importantly, it keeps everyone in the loop.
In off-site manufacturing, margins are tight, and schedules are tighter. One undocumented change can ripple through the shop and the jobsite. But when every change follows a defined process, most problems are resolved before they ever hit the bottom line.
Change will always happen. Chaos does not have to come with it.
