Workflow blueprint
Contractor invoices tied to the work that earned each line
A construction billing handoff that preserves the baseline and exposes every changed instruction before finance prepares the customer document.
Prepare contractor invoice sources without claiming estimating, job costing, tax, payment, lien compliance, certification or automatic accounting.
TL;DR — Prepare contractor invoice sources without claiming estimating, job costing, tax, payment, lien compliance, certification or automatic accounting.
Record instructions without changing scope
Give each site direction an issuer, time, consequence and status so an observation cannot become approval.
Support changed quantities and materials
Connect accepted variations to measured work, issue and return movements, supplier papers and completion references.
Admit only reviewed lines to invoicing
Finance accepts supported items and leaves disputed instructions outside the draft with their exception reason intact.
Page-specific decision aid
An accepted-scope, site-instruction, variation and invoice packet
The packet holds a renovation baseline, two later site instructions, a rejected change and an accepted additional circuit. Measured work, returned material and completion evidence support finance while the disputed instruction remains outside the invoice.
- ✓A site note cannot approve its own commercial change.
- ✓Returned material changes the source quantity.
- ✓Disputed work remains visible after invoice review.
Scope first
What Codeblix would confirm before implementation
This page is an operational blueprint. The final workflow, screens, permissions and integrations depend on your current process and agreed implementation scope.
- ✓Original scope cannot be rewritten by field activity
- ✓Variation authority precedes additional charge evidence
- ✓Measured quantity and material movement stay traceable
- ✓Estimate cost tax lien payment certification and posting excluded
