When commercial and residential general contractors look to replace manual spreadsheets with modern compliance software, SubDoc and Billy (billyforinsurance.com) frequently stand out as leading construction-focused solutions.

While both platforms specialize in the construction industry, they solve different operational challenges. Billy operates as a broader accounts payable risk management suite, uniting Certificate of Insurance (COI) tracking with electronic lien waivers and native ERP payment blocks. SubDoc focuses specifically on automated insurance certificate intelligence: 5-second AI OCR parsing, passwordless magic links for trade brokers, and seamless 1-click payment hold exports for QuickBooks and Sage.

In this guide, we evaluate how SubDoc and Billy compare across feature sets, verification turnaround times, submission UX, and pricing transparency.

AI Verification Engine: 5-Second Extraction

Both SubDoc and Billy use artificial intelligence to read Certificates of Insurance, replacing manual data entry.

Pricing Transparency: Self-Service vs. Enterprise Quotes

One of the clearest differences between the two platforms is how you get started.

Billy requires general contractors to book sales demonstrations, negotiate annual contracts, and commit to custom volume-based enterprise proposals starting at $3,500 to $10,000+ per year.

SubDoc provides 100% transparent, self-service pricing:

  • Free Forever Plan: Track up to 3 active subcontractors at $0 forever with complete AI OCR extraction.
  • Pro Tier: Starts at $20/month ($14/month intro for the first 3 months; $96/year annual) with unlimited document storage and automated renewal emails.
  • Zero Vendor Fees: Subcontractors and insurance agents never pay fees to submit paperwork.

Accounting Payment Gate: QuickBooks, Sage & Yardi

Both solutions prevent non-compliant subcontractors from being paid, but through different mechanisms:

  • Billy: Features bi-directional ERP connectors that automatically lock vendor payments inside heavy enterprise systems like Sage 300, Viewpoint Vista, CMiC, and ProcorePay.
  • SubDoc: Generates clean, 1-click CSV payment hold exports formatted specifically for QuickBooks Online, QuickBooks Desktop, Sage 100/300, and Yardi, giving controllers full control without complex API setup.

Decision Guide: Which Platform Fits Your Business?

  • Choose Billy if: You are a mid-market or enterprise general contractor seeking an all-in-one accounts payable suite that manages lien waiver exchanges, W-9 collection, and direct ERP payment blocks inside Viewpoint Vista or ProcorePay.
  • Choose SubDoc if: You want fast, dedicated software to automate Certificate of Insurance tracking, extract ACORD 25 forms in 5 seconds with AI OCR, send passwordless magic links to trade brokers, and export QuickBooks/Sage payment holds with zero sales calls.
