How-To Guides
A tech discovers extra scope on-site — a corroded pipe, an unplanned material upgrade, an additional hour of labor. He calls it in verbally. The customer nods. The invoice comes out two weeks later with line items nobody recognizes. No ReKeying means scope changes captured in the field flow directly to the invoice with a digital approval trail.
Each industry guide below follows this same framework, adapted for the specific context of that industry.
Define What Counts as a Change Order vs. Included Work
Scope creep happens when the boundary between included work and extra work is unclear. For each job type, define in writing what is included in the base price and what requires a change order.
Create a Standard Change Order Process Your Techs Can Execute in the Field
Your change order process must be usable in the field. Techs need to be able to describe the additional work, generate a price, and get customer approval — all from a mobile device while on-site.
Build a Field Price Book for Common Change Order Items
Techs should not be estimating change order pricing from memory. A digital price book with pre-built pricing for common additional work items gives techs fast, consistent pricing that maintains margins.
Get Written Approval Before Starting Any Change Order Work
The single most important rule: no work starts until the change order is approved in writing. A verbal approval from a customer who is not on-site creates a dispute. A signed change order (even via digital e-sign) is a contract.
Track Change Orders Separately From the Original Scope
Invoice line items that mix original scope with change order work are disputed at higher rates. Keep change orders on separate line items so the customer can clearly see what they authorized and when.
Review Change Order Approval Rate Monthly to Identify Barriers
If customers frequently decline change orders, the issue may be pricing, communication, or how your team presents additional work. Track approval rate by job type, by tech, and by customer type.

Work completed before approval is granted is almost never fully collected. Customers who would have approved a change order before the work was done will often dispute the same charge after the fact.
Verbal approvals are disputed on 40–60% of jobs where the customer was not present when the additional work was discovered. Written approval — even a text message reply — is far stronger.
Techs who are uncomfortable presenting additional work will undercharge or skip the change order entirely. Change order presentation is a skill that must be trained.
