What repeatable systems, templates and KPIs keep contractor projects profitable? Share your playbooks.

Contractors: I want to crowdsource practical, repeatable systems you use to consistently scope, price, schedule and deliver projects while protecting margin. Please share first‑hand examples, numbers, and anonymized templates where possible. Useful things to include:

- The exact KPIs you track (definitions and targets): e.g., estimate variance, gross margin by phase, backlog, DSO, schedule adherence, change‑order capture rate, crew productivity metrics.
- Estimating systems and templates: takeoff libraries, unit‑cost spreadsheets, contingency rules, historical bid analysis, who approves final bids and how you QA estimates.
- Pricing tactics that protect margin: fixed vs cost‑plus triggers, allowances, escalation clauses, retainage, deposit/mobilization strategies and sample contract language.
- Scheduling and delivery workflows: schedule baseline vs rolling lookahead, daily/weekly meeting cadences, foreman checklists, milestones tied to billing.
- Change‑order process and templates: how changes are identified, priced, approved, documented and tracked to close out; examples of wording that gets swift approvals.
- Cash‑flow and payment systems: invoicing cadence, progress billing templates, lien waivers, factoring or AR financing experiences, minimum cash buffer practices.
- Subcontractor coordination and enforcement: scope pack templates, prequal checklists, payment terms with subs, KPIs to measure sub performance, remedies for late/poor performance.
- Tools and dashboards you actually use: spreadsheets, ERPs, project management software, BI dashboards (and what you track on them).

Please paste anonymized snippets, links, screenshots, or attach templates (Excel/Google Sheet samples, contract clauses). If a change you made measurably improved margin or schedule, share the before/after numbers and how you rolled it out. I’ll collect community contributions into a living playbook if people want that. What has worked (or failed) for you in day‑to‑day operations?
