You are a construction operations and project controls advisor. Build a subcontractor pay application and lien waiver workflow. This is operational guidance, not legal advice.

Company role: [general contractor, construction manager, owner representative, specialty contractor, developer]
Project type: [commercial buildout, multifamily, public works, industrial, residential development, renovation]
Contract structure: [lump sum, GMP, time and materials, unit price, cost plus]
Billing cadence: [monthly, milestone, progress-based, owner draw schedule]
Subcontractor count and trades: [number, key trades, supplier involvement]
Required documents: [pay application, schedule of values, conditional waiver, unconditional waiver, insurance, certified payroll, photos]
Approval stakeholders: [project manager, superintendent, accounting, owner, architect, lender, legal]
Systems: [Procore, Buildertrend, Sage, QuickBooks, spreadsheet, email, ERP]
Retainage rules to verify: [percentage, release timing, punch list holdback, jurisdiction rules]
Change order status: [approved, pending, disputed, T&M tickets, allowance draws]
Risk concerns: [missing waivers, overbilling, duplicate invoice, unapproved scope, supplier claims, cash flow]
Deadlines: [sub cutoff date, owner billing date, payment run date]
Compliance needs: [public project, prevailing wage, tax forms, insurance, safety docs, local lien rules]

Create:
1. End-to-end workflow from subcontractor submission through payment release.
2. Pay application intake checklist with required documents and naming rules.
3. Approval routing matrix by amount, trade, change order status, and risk level.
4. Schedule of values and percent-complete review checklist.
5. Retainage tracker and release readiness workflow.
6. Lien waiver checkpoint process with items that need legal or local review.
7. Exception handling for missing documents, disputed work, rejected amounts, and late submissions.
8. Communication templates for submission reminder, missing info, approval, rejection, and payment timing.
9. Dashboard for pending apps, approved amount, retainage, aging, exceptions, and owner billing readiness.
10. Audit trail and month-end close checklist.

Do not invent lien law, retainage law, tax rules, or contract rights. Clearly flag jurisdiction-specific items for qualified review.
