Change orders are where contractors make — or lose — significant money. Here's the software that handles them correctly.
Change orders are the most financially significant workflow in residential and commercial construction. Performed correctly, they protect your margin, provide clients with cost transparency, and create a legal record of every scope change. Performed poorly — or not at all — they're where contractors lose thousands of dollars per project doing work they were never paid for.
The right software makes the change order process fast, professional, and systematically complete — so no change slips through unpriced and unapproved.
The gap most contractors experience: steps 1–3 happen in their head, step 4 happens via a verbal conversation, step 5 is a text message or a nod, and steps 6–7 never connect to the actual budget. The result is work performed but never properly billed, and disputes at closeout about what was agreed to.

Buildertrend's change order workflow is one of its strongest features for residential contractors. You document the change, price it with materials and labor line items, add markup, and present it to the client through the owner portal. The client reviews on their phone or computer, asks questions if needed, and approves digitally with a timestamped signature. The approved change automatically updates the project budget and contract value.
The client portal is the key: instead of a verbal approval or a text message, you have a documented, timestamped digital signature. When a client later questions a charge, you can show them exactly when and how they approved it.
Buildertrend — Change order workflow with digital client approval and automatic budget updates. Stop losing money on verbal approvals.

Procore's change order management covers the full commercial change order lifecycle: potential change orders (PCOs) that are tracked before pricing is complete, change order requests (CORs) to subcontractors for pricing, prime change orders presented to the owner, and change order logs with full audit trails. For commercial GCs managing dozens of change events per project across multiple subs, Procore's structured workflow is essential.
Commercial change orders also connect to subcontract management — when the GC receives an owner change order, Procore helps generate the corresponding back-charge or credit to the affected subcontract. This linkage prevents the common problem of the GC absorbing costs that should be charged back to subs.

JobTread handles change orders well for smaller contractors at a fraction of Buildertrend's cost. You create a change order, price it, send it to the client for digital approval, and JobTread updates the job budget and contract value automatically. The workflow is streamlined and the interface is clean — it won't overwhelm a contractor who's managing 5–10 projects and doesn't need enterprise complexity.

Houzz Pro's change order workflow includes itemized pricing, client presentation, and digital signature collection. For design-build remodelers where change orders often involve product substitutions or design upgrades, Houzz Pro's ability to include product images and design context in the change presentation is a differentiator — clients see exactly what they're approving rather than just a line item description.

The most expensive mistake. Software doesn't prevent you from starting work before approval, but it creates a workflow habit — submit the change, wait for approval, then proceed. When this process becomes routine, starting without approval feels wrong rather than normal.
Verbal approvals are unenforceable. "The client said yes" becomes "I never agreed to that" at closeout when the client is unhappy. Digital signature collection in Buildertrend, JobTread, or Houzz Pro creates an undeniable record.
When change orders are tracked in a separate spreadsheet, they often don't make it back into the job budget. Software that automatically updates the budget when a change is approved eliminates this gap — the budget always reflects the current contract value.
At project closeout, every unpresented or unapproved change becomes money left on the table. A change order log that shows all pending changes lets you review and ensure nothing slips through before you close out the job.
This varies by contractor and market, but common residential markup on change orders is 15–20% on materials and subs, with direct labor marked up at your established labor rates. Some contractors charge a flat change order administration fee ($150–$300) in addition to cost plus markup to account for the disruption and administrative burden. Commercial GCs typically use the markup rates specified in the prime contract.
Depends on your state and contract language. In many states, oral agreements for change orders are technically enforceable but practically very difficult to prove. Most standard construction contracts (AIA, ConsensusDocs) require written change orders. Even if your contract doesn't require it, digital signatures provide protection that "the client said yes" does not. Get it in writing — the software makes it easy.
Don't do the work. This is the single most important rule in change order management. A client who won't sign a change order before work begins is telling you they're not committed to paying for it. If the work is urgent and unavoidable, document the situation clearly in writing (email, at minimum) and note that you're proceeding under protest pending formal approval. Then follow up immediately with the written change order.
