What Should Be Included in a Contractor Change Order?

A change order is a document that records an agreed change to the original project scope, price, schedule, or another part of the project arrangement.

For example, a change order might document:

• additional electrical work
• a different material or fixture
• work removed from the original scope
• an unexpected site condition
• a homeowner-requested upgrade
• a price adjustment related to changed quantities
• a change to the project schedule

A change order is different from an invoice.

The change order documents the change to the project agreement. An invoice requests payment for work being billed. If that distinction is new to you, the guide on contractor quote vs. invoice walks through what should line up between the two.

Keeping those two documents separate makes it much easier to understand the financial history of a renovation.

The change order should explain the additional, removed, or modified work clearly enough that you can understand how it differs from the original scope.

Compare vague wording such as:

“Additional electrical”

with something more specific such as:

“Add one dedicated electrical circuit for the media equipment wall.”

The second description gives you much more context when you later compare the change order with an invoice.

When reviewing the description, ask:

• What work is being added?
• What work is being removed?
• What work is being modified?
• Can I connect this change to the original quote?

The change order should make the financial effect understandable.

Depending on the change, it may:

• increase the project price
• decrease the project price
• have no price impact

For example:

The important point is that the change itself should be identifiable.

A document that only presents a new project total without showing what changed can be much harder to review later.

Some change orders contain one fixed amount. Others include quantities, labor, materials, unit prices, allowances, or several separate line items.

There is no single level of detail that applies to every renovation, but the document should give you enough information to understand what the amount relates to.

For example:

Dedicated electrical circuit — $780

is easier to compare later than:

Electrical adjustment — $780

If a charge later appears on an invoice, clearer descriptions make it easier to identify whether the invoice relates to the approved change.

A useful change order should help you understand how the new work relates to what was originally agreed.

Ask whether the change:

• adds entirely new work
• replaces something in the original quote
• changes the quantity of existing work
• upgrades a material or fixture
• removes previously included work

This matters because simply adding the change-order amount to the original project total does not always tell the whole story.

For example, replacing a previously included $1,000 fixture with a $1,500 fixture may involve a $500 change rather than an entirely new $1,500 commitment.

The wording of the documents should make that relationship as clear as possible.

Some changes affect more than price.

A material substitution, added work, or unexpected condition can also affect timing. If the change is expected to alter the project schedule, it is useful for the change order to document that effect.

For example:

“Adds approximately three working days to the project schedule.”

Not every change will affect timing, but documenting schedule changes can help avoid confusion later.

The change order should have a clear date.

Dates help establish the sequence of the project documents:

That sequence becomes especially useful on longer renovations with several invoices and changes.

For projects with multiple changes, simple identifiers such as:

• Change Order #1
• Change Order #2
• Change Order #3

can make document tracking much easier.

The identifier can also appear on later invoices, helping you understand which approved change an invoice line relates to.

The change order should make it clear when the proposed change became an approved project change.

How approval is documented can vary by contractor, project, platform, and location. It might include:

• signatures
• initials
• an electronic approval
• another documented acceptance method

The important distinction is between a proposed change and one you have actually approved.

ScopeCheckup also keeps this distinction separate: confirming a document is not the same as approving the change itself.

Before approving, compare the change order with the accepted quote rather than reviewing it by itself.

You do not necessarily need every change order to be complicated. You simply want enough information to understand how the project is changing. For a longer walkthrough, see the homeowner change-order checklist.

Later, when the contractor invoices you, compare the invoice with both:

1. the accepted quote
2. any approved change orders

For example:

Looking only at the original quote could make the invoice appear $450 higher.

Looking at the full document history gives you the context needed to understand where the difference came from. The guide on how to review a contractor invoice before paying covers that comparison step by step.

This is why tracking quotes, change orders, and invoices together is more useful than reviewing each document separately.

For a renovation with multiple payments, try to keep:

• the accepted quote
• every confirmed change order
• every invoice
• records of payments you have made

Keeping these together creates a clearer picture of:

Original project amount + approved changes = current committed amount

Then invoices and payments can be reviewed against that evolving project commitment — the same idea behind tracking renovation costs and payments.

Change orders are easiest to understand when they are reviewed as they happen.

Weeks or months later, it can be difficult to remember why a particular amount changed or whether an invoice line related to an earlier approved change.

ScopeCheckup helps homeowners organize their accepted quote, confirmed change orders, and invoices in one project and highlight differences between them.
