Key Features
Everything you need to manage Subcontractor Change Order Log documentation professionally.
Auto-Calculated Pass-Through
Enter the sub amount and a markup percentage — the client change order amount computes itself on every row
Cost & Recovery Tracking
Running totals for approved sub cost, your markup, client pass-through, and pending sub exposure at a glance
Individual Sub CO Forms
A detailed form per sub CO with cost breakdown, pass-through table, and GC / subcontractor signature blocks
Status Workflow
Track each sub CO through Pending, Approved, Executed, and Rejected — totals recalculate as statuses change
Back-to-Back Linking
Link each subcontractor CO to its client CO number so no sub cost goes unrecovered up the chain
Exposure Before It Bites
Pending sub amounts are totaled separately so you see unapproved cost before it reaches your margin
Sub Cost In. Markup On. Client Recovery Out.
This log tracks the COST side of change management — what your subs bill you — and the pass-through that recovers it from the client.
The Sub Bills You
A subcontractor hits changed conditions or added scope and submits a change order to you. That amount is your cost — log it the day it lands.
- • Sub CO amount and backup
- • Category and reason for change
- • Submitted date starts the clock
You Add Your Markup
Your prime contract sets the overhead and profit you can add on subcontracted change work. The log applies your markup percentage per CO.
- • Default markup applied to new COs
- • Per-CO override when terms differ
- • Markup dollars computed for you
You Pass It to the Client
Sub amount plus markup equals the client change order amount. Link the client CO number so every sub cost has a recovery trail.
- • Client amount auto-calculated
- • Client CO # linked per sub CO
- • Unlinked cost = unrecovered cost
Tracking what you bill the owner?
This log is the cost side. For the revenue side — the change orders you submit up to your client — use the Client Change Order Log. Run both and your margin per change is the gap between them.

Frequently Asked Questions
A subcontractor change order log is a register of every change order your subcontractors bill to you — the cost side of change management. It records the sub's amount, your markup, and the client pass-through amount so you always know your exposure and your recovery on every change.
Yes. Enter the subcontractor amount and a markup percentage and the template calculates the markup dollars and the client pass-through amount for each change order, plus running totals for approved sub cost, markup, pass-through, and pending exposure.
A back-to-back change order pairs a subcontractor's change order (your cost) with a matching change order to your client (your recovery). The log links each sub CO to its client CO so unrecovered sub costs are visible before they erode your margin.
