Warning when the estimate has moved since signing

If the estimate now totals more than the signed contract, the editor shows both figures and the exact difference and tells you to raise a change order.

What it is

An amber banner in the estimate sidecar, shown only when the signed total and the current estimate total differ by a cent or more. It states the signed amount, the current estimate amount, and the gap, and says the invoice will stay on the signed figure until a change order covers the difference.

Also called: estimate changed after contract · scope crept · difference between estimate and contract · unbilled extras

Signature
The amber banner reading 'Billing the signed contract amount. The contract your customer signed is $34,016.87, but the estimate now totals $37,828.19 (a difference of $3,811.32).' src/components/invoices/InvoiceEditor.tsx. Sample data — no customer information appears here.
How it works
  1. 1Both totals travel on the estimate source: signedTotal from the contract, estimateTotal from the approved link.
  2. 2The banner renders when both exist and differ by at least $0.01.
  3. 3The insert buttons continue to use the signed total — the gap is never silently added.
Why we built it

When the live estimate and the signed contract disagree, both silent options are wrong: bill the newer number and the customer is charged for scope they never agreed to; bill the old one quietly and the builder never learns that work has been added with no change order behind it. The gap is shown instead — both figures and the difference between them — so somebody decides whether it is an error or an extra that needs paperwork.

The problem
  • Work added after signing being either billed without agreement or never billed at all.
  • A builder unaware their own estimate had changed.
Sound familiar?
What you get
Scope creep is caught at billing time, in dollars.
The remedy is named on the spot: raise a change order.
