The Problem
Why operators buy this pack.
- 01
Your team wants to build a custom Excel tool because the off-the-shelf option "doesn't fit how we work."
- 02
Or worse — you bought the platform, paid for the implementation, and 8 months later the PMs still use spreadsheets.
- 03
Every build vs. buy debate ends in a hallway argument, not a defensible decision.
- 04
You have no way to put a real number on internal build cost, maintenance burden, or adoption risk.
This pack replaces the hallway argument with a structured construction software decision tool that produces a one-page memo.

Sample Output
What you actually get back.
Input
We're thinking about building a custom job costing dashboard in Excel vs. buying a module in our ERP. We have 2 PMs and a controller. The ERP add-on is $800/month.
Output
BUILD vs BUY — JOB COSTING DASHBOARD RECOMMENDATION: BUY (ERP add-on) Confidence: HIGH KEY DRIVERS • 3-yr TCO — Build: ~$72K (40 hrs build + 6 hrs/mo maintenance @ $150) • 3-yr TCO — Buy: ~$28.8K ($800/mo, native integration) • Adoption risk — Build: HIGH (single-owner dependency on Excel author) • Adoption risk — Buy: LOW (in-app, no second system) RED FLAGS IF YOU BUILD 1. Controller becomes the bottleneck for any change request. 2. Loss of audit trail vs. ERP-native costing. 3. Reporting won't roll up to your existing dashboards. DECISION GATE Proceed with ERP add-on. Pilot with 1 PM for 30 days before full rollout.
