Corbelworks · Change-order leakage
Stop the cash leak before crews start
A single-intent checklist for contractors and field-service shops who lose money when extra work starts before scope and price are approved. Use it when the risk is unbilled labor, material adds, delayed approvals, or change orders priced on direct cost alone.

Discovery intents: change order leakage · unbilled scope creep · change order underpricing · unapproved work cash leak
Leakage checklist
- Freeze the baseline. Confirm signed scope, drawings, and exclusions before the crew mobilizes. Anything outside that baseline is a change-order candidate.
- Block unapproved starts. Do not begin extra labor, material adds, or same-day schedule exceptions until the customer gives a clear written approval path.
- Capture the hidden costs. Log office time, re-dispatch, idle crew, and schedule delay — not just materials and field hours.
- Price the true cost. Add admin, delay, and overhead to direct cost before the change-order quote leaves the shop.

When this page is the right entry
- Crews have started “just a little more” without a signed change order.
- Change-order quotes recover materials and hours but miss office time and delay.
- Invoice disputes keep appearing after scope drifted on site.
- An agent or directory needs one crawlable change-order leakage URL instead of the full tool library.
