CHANGE ORDERS · 9 GUIDES

A CHANGE ORDER YOU DID NOT BILL IS A GIFT TO THE GC.

QUICK ANSWER

Most change order losses start when work begins before any documentation exists. The average commercial project has 10 to 30 change orders, and each one needs a written potential change order before work starts, a price at full burdened cost plus overhead and margin, and a submission inside 48 hours. A 15 percent cap on cost pays a 13 percent margin, so even approved change orders lose money when they are priced from the wrong base.

On a $3M project with active scope changes, unbilled change orders commonly represent $80K to $200K of performed work that never reaches an invoice, and one change order audit surfaced $310K. An $11,200 change order is worth $16,198 once 13 percent overhead and 22 percent gross margin are priced in. The guides in this hub cover the paper, the price, the billing and the WIP entry for every change order.

THE DEFINITION

WHAT IT MEANS.

A change order is a written agreement that adds to or alters a subcontract's scope, price or time, and it becomes a financial event only once it is priced, approved, recorded in the WIP schedule and billed on a pay application.

WHERE THE MARGIN GOES

WHY IT BREAKS.

01

Work Starts Before the Paper Does

A verbal direction from a superintendent or a sketch on a napkin is not a change order. Every scope change gets a written potential change order before work starts, and when the GC directs you to proceed first, you proceed under written protest. Escalation follows at 30, 45 and 60 days.

02

The Markup Cap Shorts the Margin

A cap of 10 percent overhead and 5 percent profit on cost pays a 13.0 percent margin, because markup divides by cost and margin divides by price. The 12 to 15 percent of overhead that change work consumes is rarely priced into any of them.

03

Billing Lag Turns Cost Into a Loan

Approved work deploys cost three weeks before it collects, and a $40,000 change order can tie up $52,500. Disputed scope can go unpaid for 6 to 24 months. Submitting inside 48 hours and booking the change the day it signs keeps the WIP schedule honest.

The onboarding fee covers migrating your books back to the start of your last taxable year and getting you fully operational in 60 days. It's billed once, with your first invoice. It's the same for all three tiers. Your first month is prorated, and your monthly engagement starts on the first of the first full month.

Range reflects the three tiers below. Which one you're in depends on how much of the work you want off your desk. No payroll. No hidden line items. The onboarding fee is right here in the table.

Core

You stop guessing.

You get the CFO work. Job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a meeting every month that ends in decisions and never in a report.

Your bookkeeper still does the books.

Executive

You stop touching the books.

Everything in Core, and we do the bookkeeping and the controllership as well. Your office stops answering coding questions and stops fixing a reconciliation that will not balance on the last day of the month.

We do the books. No payroll.

Strategic

Every job shows its margin while it is still open.

Everything in Executive, plus the job costing and WIP platform set up, loaded with your cost codes, and managed for you every month. You never have to learn it.

We do the books, the job costing, and the software. No payroll.

COMMON QUESTIONS

FREQUENTLY ASKED.

At full burdened cost plus overhead plus margin, and not at a field-guess time and material number. A 15 percent all-in cap on cost pays only a 13.0 percent margin, so check the math before you accept the cap.

Inside 48 hours of the direction. A same day email records the scope, and a 48 hour price keeps the change inside the window where the GC still has a reason to approve it.

The cost is booked to the job with no revenue against it, the WIP schedule is distorted, and the change gets disputed after the leverage window closes. If the GC directs you to proceed, do it under written protest.

Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we do the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still open, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
