Head Contract
Head contract software with retention, milestones and terms in one place
The head contract, configured once, drives your milestones, retention, EOT logic and variation rules. No more "check the PDF" moments six months into the project.
Claim Schedule (BOQ)
Break contract value into stages once. Every claim populates from the schedule.
Head contract variations
Raise, price with margin, generate PDF for client sign-off, add to contract value.
Cost-to-revenue traceability
Link a subbie variation to a head contract variation. See margin per scope change.
THE PROBLEM
Retention released on a subcontract because nobody read the head contract clause on defect liability period.
Head contracts live in a PDF. Terms get referenced when someone remembers. Retention rules, defect liability periods, EOT clauses and variation notices all rely on the memory of one senior CA who read the contract 18 months ago.
Plexa reads the head contract at project setup and encodes the terms. Retention, milestones, EOT logic and variation rules become live workflows, not memory.
Head contract terms across every active project
Different clients. Different contracts. Different retention rules. One view of the terms that matter, per project, so nothing slips because nobody remembered the clause.
