I've been working on an AI-assisted subcontractor management system. It starts with the signed subcontract and agreed scope, budget and programme. Basically after procurement is done and you have locked in the sub-contractor. From there, we have each step in the process and some small, discrete Claude skills that you run to support each process. We also have a library of business templates and project information that sits behind them. Setup and mobilisation: summarise obligations, build a checklist for documents and site readiness, and agree how progress will be reported. Delivery: check performance against the plan, review payment claims against verified progress, assess variations and draft notices. For variations, check entitlement first, then price and time. This Close-out: check the final account and handover requirements, then record lessons learned and subcontractor performance for future projects. The system combines organised project records, shared business information and reusable AI workflows that you customise to your processes. Check out the walk-through: https://youtu.be/04Vw2WqI2dE
