Contractor Management, Built Into the BuildX Platform

Subcontractors are usually the single largest cost on a construction project — and the least controlled. The BuildX Contractor Management module puts the entire relationship in one controlled flow: work orders against agreed rates, RA-bill certification against measured quantities, retention and advance tracking, and performance scoring across projects. Every subcontractor bill is checked against its order before payment, so the biggest leak in the biggest cost is closed.

Inside the module

What BuildX Contractor Management Does

This module is part of the integrated BuildX platform — so it shares one source of truth with cost, billing, procurement and site data, and is built and supported by a certified Frappe partner with a large in-house team.

📄

Work Orders & Rates

Issue subcontractor work orders against agreed rate schedules, so every bill is checked against what was actually ordered.

RA-Bill Certification

Certify subcontractor RA bills against measured quantities and the work order, catching over-billing before it is paid.

🔒

Retention & Recovery

Track retention held and advances given per contractor, recovered and released on schedule, never lost.

🔁

Variation Control

Capture and price work beyond the order, so extra work is paid deliberately rather than discovered in an inflated bill.

📊

Contractor Performance

Score and track contractor performance across projects — quality, timeliness, reliability — to inform future awards.
