Managing Change Orders Without the Headaches

Change orders are the single biggest source of contractor-customer disputes. Surveys of construction litigation show roughly 40% of cases trace back to a disputed scope change — work that the contractor performed believing it was approved, that the customer believes was either included in the original price or never authorized.

The fix isn't getting better at arguing. It's building a one-screen, written change-order process that's so frictionless your crews actually use it on every change, no matter how small.

Why Verbal Change Orders Always Fail

It's never the big change orders that cause problems. The $8,000 kitchen island addition is going to get a signed contract no matter what. It's the dozen $200-$800 scope creeps that destroy trust: "while you're back there, can you also...", "oh I forgot to mention the outlet needs to move...", "actually we want soft-close hinges on those instead."

The contractor remembers them as additions. The customer remembers them as "things I assumed were included." Both sides are arguing in good faith — they just never wrote anything down. By the time the final invoice surfaces $4,200 in extras, the trust is gone and the relationship is over.

The Three Rules

1. No work begins without a written, priced, signed change order. No exceptions. "Sure we can do that, I'll send you a quick CO right now" is the entire script.
2. The CO process has to take under 90 seconds, from request to signature, or crews won't use it. This means it must be mobile-first, with auto-filled customer info, line-item-style entry, and one-tap customer signature.
3. The signed CO must update the project total automatically. A standalone PDF that doesn't flow into the running contract value is a recipe for "wait, what's the total now?" arguments at billing time.

Pricing the Change Order

Most contractors underprice change orders because they feel awkward charging for "small" changes. Don't. Change orders carry premium pricing for two legitimate reasons: they disrupt your scheduled workflow (which costs you efficiency on the rest of the job), and they expose you to lower-volume material orders (which cost you the contractor discount).

• Standard markup on materials: 25-40% (versus your usual 15-20% on contract work).
• Labor: charge your fully-burdened hourly rate, not your discounted contract rate.
• Mobilization fee: many contractors add $150-300 for any CO that requires an extra trip back to the site.

The Mobile Signature Loop

The single biggest unlock in modern change-order management is the customer signing on their own phone. Email the CO, customer reviews it on their phone in 20 seconds, taps Sign, and the CO is binding. No clipboard handoffs, no waiting for the customer to be home, no "I'll sign it tonight" that turns into next week.

Tracking the Approved Total

Every approved CO needs to update the running contract total visible to both you and the customer. The current-best practice is a customer portal where the customer sees the original contract value plus the chronological list of approved COs, with a current total at the bottom. No surprise at final-invoice time, because both parties have been watching the number climb in real time.

What About Time?

Don't forget to extend the completion date with every CO. A CO that adds 4 hours of work to a project might add a full day to the schedule if your crew is already booked. The CO form should have a "schedule impact" field; "no impact / 1 day / 2-3 days / 1+ weeks" covers 95% of cases.

The Customer Conversation Changes

When change orders are friction-free and written down, the conversation with the customer shifts from "you owe me $4,200 in extras" to "you approved $4,200 in changes." The latter doesn't cause disputes. The former ends relationships.

FieldsHub change orders are designed around this 90-second mobile workflow: auto-filled customer, AI-suggested line items based on the project context, one-tap customer signature, and automatic project-total updates.
