# Joint Check Parsing for General Contractors

*/Opportunities/Joint_Check_Parsing_for_General_Contractors*

## Opportunity Overview

**Wedge**: Begin specifically with commercial drywall and concrete subcontractors, scopes that carry the highest volume of sub-tier material suppliers and thus the most joint check requirements. Win this niche by delivering zero-error payee extraction and lien waiver matching, then expand into mechanical and electrical scopes before capturing the entire monthly pay application review cycle.
**Timing**: Modern large language models possess the context windows and spatial reasoning required to reliably extract multi-party payee entities, payment splits, and conditional lien waiver terms from highly variable PDF construction agreements, a task where legacy optical character recognition consistently failed.
**Why This I C P**: Mid-market commercial general contractors bear the strict financial liability for mechanics liens from unpaid suppliers but lack the massive back-office accounting headcount of top-tier enterprise firms to manually process the high document volume.
**Size Of Prize**: ~40,000 mid-market US commercial general contractors × ~$20,000 per year in dedicated compliance labor spend for sub-tier payment routing = ~$800M annual prize.
**Gap Narrative**: General contractors issue joint checks to subcontractors and sub-tier suppliers to prevent mechanics liens, requiring complex multi-party payment routing. Standard construction accounting systems cannot natively read unstructured joint check agreements, forcing compliance clerks to manually cross-reference pay applications, lien waivers, and check runs to ensure the correct parties receive payment.
**Defensibility**: Defensibility stems from deep workflow lock-in and a compounding entity graph. As the system processes joint checks across multiple projects, it builds a deterministic map of local sub-tier suppliers and their standard payment terms, making the matching engine continuously faster and harder to rip out for a generic document parser.
**Why This Thesis**: An Agent approach directly replaces the human compliance clerk by reading the unstructured joint check agreement, matching it to the submitted pay application, and autonomously updating the payment routing logic in the core ERP.

## Opportunity Market Sizing

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**S A M**: ~$400-600M representing commercial and industrial general contractors managing complex multi-tier subcontractor payments
**S O M**: ~$10-25M realistic 3-year capture targeting mid-market commercial general contractors
**T A M**: ~100,000 US general contractors × ~$15,000/yr software allocation ≈ $1.5B
**Growth Rate**: ~8-12%/yr, driven by rising material costs and stricter sub-tier lien avoidance compliance
**Paid Comparable Spend**: ~$20,000-40,000/yr per firm in fractional accounts payable and compliance clerk labor to manually verify joint check agreements and track lien waivers

## Opportunity Win Conditions

**Kill Thresholds**:
- Human-in-the-loop correction rate exceeds 20% after 30 days
- Month-two AP clerk active usage drops below 40%
- Average contract value stays below $15,000 annually
- Integration setup with Procore or ERP takes longer than 21 days
**Leading Metrics**:
- Time from agreement document upload to structured data availability
- Percentage of extracted joint payee fields requiring manual user correction
- Weekly volume of joint checks automatically matched to subcontractor invoices
- System-flagged payment block rate for missing sub-tier lien waivers
**What Proves Right**: Mid-market commercial general contractors upload joint check agreements and rely on the extracted payee data without manual double-verification. Accounts payable teams process subcontractor pay applications through the system weekly, maintaining a week-four retention rate above sixty percent. Customers convert to paid annual contracts at twenty thousand dollars after seeing the software catch missing sub-tier lien waivers before payment issuance.
**What Proves Wrong**: Accounts payable clerks continue to manually cross-reference every parsed joint check agreement against the original PDF, eliminating any labor efficiency gains. The extraction engine fails to read handwritten or non-standard sub-tier supplier terms, requiring human-in-the-loop escalation on over half the uploads. Pilot customers churn within sixty days because the time required to correct extraction errors exceeds the time previously spent on manual entry.

## Opportunity Build Profile

**Hardest Part**: Extracting multiple payee entities from non-standard, occasionally handwritten joint checks and perfectly reconciling them against partial lien waivers without false positives.
**Min Viable Scope**: Build exclusively for GCs managing tier-2 supplier payments via joint checks. Leave out direct ACH payment execution, ERP write-backs, and general invoicing; focus strictly on parsing incoming agreements, matching dual payees, and flagging missing lien waivers.
**Cold Start Problem**: The system lacks a training corpus of executed joint checks and corresponding lien waivers to tune the extraction models. Break this by partnering with one mid-sized regional GC to ingest their archived Procore project files as the seed dataset.
**Time To First Value**: 1-2 weeks of onboarding to map historical supplier data before the first live pay app cycle
**Data Moat Available**: true
**Technical Difficulty**: Moderate
