ProjectScope Bids is a lightweight bidding and contract platform specifically for excavation and earthwork subcontractors working under GCs. Currently, job scopes are fuzzy voice notes and PDFs in WeChat; variations and extra work create constant disputes and delayed payments. We provide template-based scopes tailored to earthwork (excavation depth, soil type, haul distance, equipment class, risk clauses) that subcontractors can send as structured quotes, which GCs approve with click-through contracts and integrated change orders. Value props:

• For subcontractors: faster, more professional quoting, fewer unpaid extras, and a track record of unit prices and margins across projects.
• For GCs/project managers: comparable bids from multiple subs, clearer responsibilities, and digital records that reduce legal and accounting friction.
• For both sides: integrated photo-based progress logs and signed acceptance per phase. Defensibility from becoming the system of record for excavation quotes and variations, accumulating pricing benchmarks by region. Monetization via SaaS subscriptions plus per-transaction service fees on accepted bids.
