Syntora offers expert help for general contractors seeking custom automation for subcontractor document management. We build robust systems that integrate with existing project management tools, leveraging technologies like FastAPI, AWS Lambda, and Claude API to automate document validation and compliance tracking. Syntora focuses on delivering tailored engineering engagements to solve specific operational challenges.
The scope of an engagement depends on several factors, including the number of document types requiring automation (e.g., COIs, W-9s, lien waivers), the complexity of data extraction, and the specific integration points with your existing project management software. For instance, an engagement involving a few standard document types and an established API like Procore would involve a different discovery and development path than one requiring custom integrations for many document types from disparate sources. Syntora’s approach prioritizes understanding your unique operational workflow to design and deliver a system that precisely addresses your challenges.
Why Does Subcontractor Document Management Break in Construction?
General contractors use Procore or Autodesk Construction Cloud for project management, but their document handling is generic storage. They can store a Certificate of Insurance (COI), but they cannot read the PDF to verify the policy limits match the contract requirements. This forces project managers to manually open and check hundreds of PDFs.
A GC with 7 active projects has 15 subcontractors on a new job. The project manager emails requests for COIs, W-9s, and safety plans. Two subs send an outdated COI, one sends a policy with liability limits below the $2 million required, and three forget to add the GC as an additional insured. The PM only discovers these errors by manually reading all 15 PDFs, a 4-hour task that delays onboarding.
Relying on email and generic cloud storage like Dropbox or SharePoint creates data silos. There is no central dashboard to see which subs on which projects are non-compliant. The workflow breaks because the tools treat documents as static files, not as sources of critical, structured data needed to manage project risk.
How Syntora Builds an AI-Powered Document Validation System
Syntora would approach the problem by first conducting a detailed discovery to understand your current document intake processes, critical document types, and compliance requirements. This initial phase involves identifying the key data fields to be extracted from documents like COIs and lien waivers (e.g., policy number, effective dates, coverage amounts).
The system would connect to your document source, whether it's an S3-compatible storage system via Python with the boto3 library, a shared drive, or a Procore account using the Procore API. Syntora would build a FastAPI service to orchestrate the entire document validation pipeline. When a new document is uploaded, a webhook would trigger an AWS Lambda function. This function would then send the document to the Claude 3 Sonnet API with a structured prompt designed to extract the necessary key fields into a JSON format. We have experience building similar document processing pipelines using Claude API for financial documents, and the same pattern applies effectively to construction-related documents. The extracted data would be securely stored in a dedicated Supabase table.
The core logic, implemented as Python functions, would compare the extracted data against your project-specific requirements, also stored in Supabase. This includes checking for valid policy expiration dates, ensuring coverage limits meet specified minimums (e.g., $2 million), and verifying 'additional insured' clauses. The validation results (pass, fail, or flagged for review) would be written back to a custom field in your project management tool via its API, providing immediate compliance status updates.
To provide visibility, Syntora would develop a simple, real-time dashboard using Vercel and Retool, offering an overview of subcontractor compliance across all active projects and proactively flagging expiring policies. For operational reliability, we would configure structlog for structured logging and set up CloudWatch alarms to send Slack notifications for any API error rate exceeding a defined threshold. Typical build timelines for a system of this complexity, including discovery and deployment, range from 8 to 16 weeks, depending on the number of document types and integration complexity. The client would typically need to provide access to existing document storage, project management APIs, and collaborate on defining compliance rules. Deliverables would include the deployed automation system, source code, documentation, and a knowledge transfer session.

Frequently Asked Questions
- How much does a custom document automation system cost?
- The cost depends on the number of unique document types and the complexity of the integration with your project management system. A typical project to handle 3-5 standard forms like COIs and W-9s is a fixed-fee engagement. We provide a firm quote after a 30-minute discovery call where we review your specific documents and workflow.
- What happens when a subcontractor uses a non-standard insurance form?
- The Claude API is robust to layout changes, but if it cannot extract a required field with high confidence, it flags the document for manual review. The system sends the PDF link to a designated project admin in Slack or email. This happens with less than 2% of documents, ensuring you never miss a non-compliant submission.
- How is this different from using a Procore App Marketplace tool?
- Marketplace apps are one-size-fits-all SaaS products with per-user monthly fees. They cannot be customized for your specific contract requirements or unique lien waiver formats. Syntora builds a system you own, tailored exactly to your validation rules, with no recurring user licenses. The code is yours to modify forever.
- Can this system handle lien waivers?
- Yes. Lien waivers are a common use case. The system can extract the project name, subcontractor name, payment amount, and signature date. It then cross-references this information with your accounting system's data (e.g., QuickBooks, Viewpoint Vista) to verify the payment amount is correct before a project manager approves it.
- What kind of security is in place for sensitive documents?
- Documents are processed in memory and never stored long-term on our servers. We use AWS Lambda, which runs in a secure, isolated environment. All data in transit is encrypted with TLS 1.2. The extracted data is stored in your private Supabase database, and we implement role-based access control so only authorized users can view it.
- Do we need an IT team to maintain this after you build it?
- No. The system is designed for low maintenance. It runs on serverless infrastructure (AWS Lambda), so there are no servers to manage. We provide a detailed runbook that explains how to monitor the system and handle common alerts. For any deeper issues, we offer an optional monthly support plan for ongoing maintenance and updates.
