SiteLedger - Contractor Progress & Billing

A project management and billing system for a contracting company with several sites. It replaces the three separate lists that QC, billing staff and contractors each kept, and the arguments over the differences between them.

How it works

• The contractor logs work against the signed bill of quantities
• QC verifies it, adjusts it with a reason, or rejects it
• Every cycle (14 days by default) the contractor requests a billing built only from QC-verified quantities
• Staff price it, the main engineer approves it as an invoice, and payment is recorded as a receipt

What is in it

• Five roles, each seeing only what they need: owner, main engineer, QC, billing staff, contractor
• Multi-branch: every site has its own colours, banner and engineer in charge
• Contracts and BOQ with claimed, verified, billed and remaining quantities per line
• Full traceability: every log shows who handled it at each step
• Attendance with a gate-terminal simulator (face, QR or phone geofence)
• Queries settled on the record instead of in a spreadsheet
• Every list sorts and searches every field; every record is a link
