Construction Change Order Software

Change orders approved — not chased.

Ressio creates change orders directly from your flagged estimate line items. Your client approves via magic link from any device. The approval is timestamped, logged, and flows back into your budget automatically. No separate form. No version confusion. No signature chasing.

No commitment. 30 minutes. We'll walk through your workflow.

Change orders that start from your estimate

Most change order software is a blank form. Ressio change orders are built from your actual project data — flagged line items, real numbers, and a direct path to client approval.

Built from the estimate — not a separate form

When scope changes, you flag the affected line items in your estimate. Ressio builds the change order from those items — quantities, unit costs, and totals already populated. You're not retyping numbers or copying from a spreadsheet. The change order reflects the real cost the moment you create it.

  • Flag estimate line items to start the change order — no manual entry
  • Labor, materials, and markup pulled from your estimate automatically
  • Change order total calculated from actual line item costs
  • Attach photos or files to document exactly what changed and why

Client approves via magic link — no login required

Send the change order and your client gets a notification with a magic link. They tap it, see the full change order on their phone or laptop, and approve or decline. No account. No app download. No printing, signing, and scanning. The approval is recorded the moment they tap.

  • Magic link works on any device — phone, tablet, laptop
  • Client sees full line item detail before approving
  • Approval captured with timestamp the moment client acts
  • Declined change orders log the decision with a full audit trail

Approved change orders update the budget automatically

The moment a client approves a change order, the revised contract amount and updated cost projections flow into your live budget. You don't have to manually reconcile the change — the project margin recalculates in real time. Your financial picture stays current as the project evolves.

  • Contract value updates automatically on approval
  • Budget line items revised to reflect the approved scope change
  • Margin impact visible immediately — no manual reconciliation
  • Change order history attached to the project for closeout reference

Full audit trail — every change documented

Every change order in Ressio carries a complete history: who created it, when it was sent, when the client viewed it, and when they approved or declined. If a client disputes a change six months later, you have a timestamped record with every detail. That conversation ends quickly.

  • Timestamped log of creation, send, view, and approval events
  • Client name and approval date stored on every change order
  • Full line item detail preserved — what was changed, at what cost
  • Unified approvals view — all pending change orders in one place

From scope change to signed approval in three steps

01

Flag the line items

When scope changes, flag the affected estimate line items. Ressio builds the change order from those items — quantities, costs, and totals already filled in. Add a description and any supporting photos or files.

02

Send to the client

Send the change order with one click. Your client receives a notification with a magic link. They open it on any device, review the full detail, and approve or decline. No login required.

03

Budget updates automatically

Approval triggers an automatic budget update — revised contract value, updated cost projections, and recalculated margin. The change is logged with a timestamp. Nothing to reconcile manually.

Change orders connected to your full project workflow

Ressio change orders don't live in isolation. They pull from your estimate, update your budget, connect to the client portal, and feed your invoices — all without manual steps.

Client approvals via magic link require no Ressio account — your client taps the link and approves from their phone.

What builders say about change orders in Ressio

Ressio is so easy that a 70-year-old couple — one of whom has dementia — have been able to approve selections and change orders, follow the daily log, and send messages.

Before Ressio, change orders were a mess — I'd email a PDF, they'd say they never got it, and a month later we'd be arguing about whether it was approved. Now I just send the link and I have proof.

The fact that it pulls from the estimate is huge. I'm not retyping numbers into a change order form — it's already there. I just flag the lines, add a note, and send it.
