Contractor quoting

How to Change a Contractor Quote After the Customer Adds Work

Customers add outlets, paint another room, or ask for a bigger clean-up mid-job. Here is the simple rule for keeping the paperwork clean and getting paid for the extra work.

Quick answer

  • If the customer has not accepted the quote yet, send a revised quote that shows the new line items, the new total, and what changed. Do not quietly overwrite the old total.
  • If the customer already accepted or signed, do not edit the original quote. Price the added work separately and get written approval before you start it.
  • In many states, home-improvement changes must be written. California, for example, requires change orders that describe the extra work, the price change, and any schedule effect before the new work begins.

Ask one question before you change anything

Has the customer already accepted or signed the quote? That single answer decides whether you revise the estimate or create a change order. Mixing the two is how jobs get fuzzy and unpaid.

SituationWhat to sendWhen to start the extra work
Quote sent, not acceptedRevised quote with a new date or versionAfter the customer accepts the revised version
Quote accepted or signed, work not startedRevised quote or written change order, then re-approvalAfter the new approval is in writing
Work already startedSeparate written change orderOnly after the change order is approved
Acceptance is the line. Before acceptance, revise. After acceptance, document the change separately.

If they have not accepted yet

Confirm the new request in writing. Then rebuild the estimate with the added scope as clear line items. Keep the earlier version in your records so you can show what changed.

  1. Restate the added work in plain language and get the customer to confirm it.
  2. Price the new labor and materials at your normal rates.
  3. Show added lines separately so the customer can see the bump.
  4. Update the total, deposit if needed, and valid-until date.
  5. Label the document as revised and send it for approval again.
  6. Do not start the new work until that revised version is accepted.

Short revision note you can paste above the new total

Revised quote for [customer / address].

Change requested: [describe the added work].

Original scope total: $[amount].

Added work: $[amount].

New total: $[amount].

This revised quote replaces the earlier version dated [date]. Please review and approve before we schedule the added work.

If they already accepted or you already started

Treat the accepted quote as the baseline. Do not rewrite history by editing that document in place. Price the addition, write it down, and get approval before you swing the hammer on the new work.[4]

The Federal Trade Commission tells homeowners to get a written contract that covers how change orders are handled, because extras can change cost and schedule. That same discipline protects you when a customer asks for more mid-job.[1]

Rules vary by state. In California, home-improvement contracts and changes generally must be in writing, and a change order should describe the extra work, the amount added or subtracted, and the effect on progress payments or completion before the new work starts. Minnesota also expects residential building contracts and change orders in writing. Check your own state rules when the job is large or regulated.[2][3]

  1. Pause before doing unpaid extras, even if they feel small.
  2. Write the scope of the added work.
  3. Show the dollar change and any schedule change.
  4. Get a signature, written approval, or clear digital acceptance.
  5. Keep the original accepted quote unchanged for your records.

Worked example: paint one room, then add a hallway

You quoted $1,850 to paint one bedroom, walls only, two coats, including prep of nail holes. The customer accepts. On day one they ask you to paint the hallway too.

DocumentWhat it shows
Accepted quoteBedroom walls only: $1,850
Change orderAdd hallway walls, same prep and two coats: +$650. New job total: $2,500. Schedule: +0.5 day.
The first quote stays as accepted. The hallway is priced and approved on its own document.

Mistakes that cost money

  • Doing the extra work first and sending a higher invoice later.
  • Editing the old PDF total without explaining the change.
  • Leaving two active quotes open so the customer can approve the wrong one.
  • Calling a scope add a tiny favor when it still needs time and materials.
  • Assuming a text that says sounds good covers a signed change-order rule in your state.

Keep revisions easy to follow

The goal is a clean trail: what was quoted, what was added, and what the customer approved. In Jorvio you can update line items, resend a clear quote link, and keep the customer reviewing one current version instead of hunting through old texts and PDFs.

Frequently asked questions

Should I revise the quote or issue a change order?

Revise the quote if it has not been accepted yet. After acceptance, keep the original as the baseline and document the addition with a written change order or a clearly labeled revision that the customer approves again.

Can I just raise the invoice at the end?

That is how payment fights start. Price and approve extras before you do them whenever you can. An invoice should match work the customer already agreed to pay for.

Do change orders always have to be written?

Many states require written changes for covered home-improvement work. California is a clear example. Even where the law is softer, written approval is still the safest habit.[2][1]

What if the added work is only an hour?

Still write it down if it changes the price or schedule. Small unpaid extras add up across a month of jobs.
