Change order software: document the extra work and get paid for it

When the job changes, the paperwork has to change with it

Every remodeler knows this moment. You pull up the tub, and the subfloor underneath is mush. Or the client walks in on day four and says, “While you’re here, can you also…” Neither one is a problem on its own. The problem is doing the extra work on a handshake, then trying to collect for it at the end, when the client remembers the conversation differently than you do.

A change order is the written record of added, removed or revised work, its price and the client’s approval. Change order software keeps that record tied to the original scope, with the photos and the client’s answer attached, so nobody has to rely on memory. This guide shows what a change order must contain, a complete example, and the contract math that keeps approved, pending and credited work straight. We make one of these tools, EstiMate, and there is a short overview of it at the end.

Two kinds of change, and why the difference matters

The job found something. Rot under the tub, wiring that isn’t to code, a joist someone notched in 1974. This is a necessary repair you couldn’t see when you priced the job. Explain the condition, show the photos, price the fix.

The client wants something. A better tile, an extra outlet, a niche in the shower. This is a choice. Show what changes and what it costs, and let them decide.

Keep the two apart on the paperwork. A client who reads “additional bathroom work: $2,000” can’t tell whether you found a problem or upsold them, and that is where trust goes to die. A client who reads “subfloor at tub found rotted, 24 sq ft replaced, photos attached” understands exactly why the price moved.

What every change order must record

1. The original job it belongs to.
   Which contract, which room, which line. A change order floating on its own in a text message is worth very little.
2. What changed and why.
   The condition found or the request made, in plain words. Separate what you saw from what still needs confirming.
3. The work, specifically.
   What is added, removed or revised, with the quantity: “replace 24 sq ft of subfloor,” not “fix floor.”
4. Photos.
   Where they explain the condition. The rotted subfloor, the notched joist.
5. The price, and any credit.
   If the change removes work, show the credit too, not just a new, higher total.
6. The schedule impact.
   Extra days, if any. Clients get angrier about surprise delays than surprise costs.
7. The approval.
   Who approved it and when, before the work is done.

Example: the subfloor under the tub

Here is that change order written out. Prices are illustrative.

Notice the joists line. Saying what is fine is just as useful as saying what is broken: it tells the client the bad news has a boundary.

The contract math: approved, pending and credits

Here is where jobs get messy. Change orders pile up, some approved, some waiting, one that took work out. The client asks “what do I owe?” and three people give three answers. The fix is to keep each state separate. One illustrative job:

The current contract value is $29,800. The heated floor is not in it, because nobody has said yes yet. The day the client approves it, it becomes $31,000. Until then, a pending request is not an instruction to do the work.

For investors running their own flip, the same ledger matters for a different reason: approved changes move the repair budget, and the repair budget moves the profit. Carry them back into the deal numbers instead of discovering them at closing.

When to write one: before the work, every time

The rule is simple and almost everyone breaks it: write the change order before you do the work. Not after. Not at the end of the week. Before.

It feels slower on the day. It is much faster than the alternative, which is a final invoice with three surprise lines, a client who “never agreed to that,” and you deciding whether $3,000 is worth an argument. Get the approval in writing (an online approval works, as long as it matches your contract’s terms), then pick up the saw.

Templates help with the changes you see all the time, like a client-requested tile upgrade. Just fill them with this job’s photos, quantities and approval, not last job’s.

Test any change order tool on one real change

1. Tie it to the job.
   Start the change order from the original scope. It should know which job and which room it belongs to.
2. Attach the photos.
   From your phone, on site, in the moment.
3. Add a credit.
   Take something out. The credit should show, not just a new total.
4. Leave one pending.
   The current contract value should not include it until it is approved.
5. Send it.
   Could the client understand it and approve it from their phone in a minute?

Pricing the extra work correctly is covered in remodeling estimating software, and the proposal it changes in contractor proposal software.
