Constrafor built something genuinely useful: a free universal prequalification form that subs fill out once and share with any GC. Billy built something different: a prequalification process that connects directly to live COI tracking, ERP sync, AI endorsement review, and automated annual renewal. Here’s when each is the right choice.
What Constrafor Actually Does
Constrafor is a construction finance and prequalification platform that offers, among other things, a free universal prequalification form. The core insight behind their prequal product is smart: instead of every GC maintaining their own proprietary prequal form that subs have to fill out repeatedly, Constrafor provides a standardized form that subs complete once and can share with multiple GCs.
What Constrafor’s prequalification tool does well:
- Reduces the friction for subcontractors who prequalify with many different GCs
- Provides a standardized data structure that GCs can compare across subs
- No cost to either GCs or subcontractors for the basic prequal tool
- Covers standard prequal sections: financial, safety, insurance, references
- Connected to Constrafor’s broader construction finance product (early pay, supply chain financing)
Where Constrafor’s prequal tool ends: once the form is submitted and reviewed, the compliance lifecycle is yours to manage. Constrafor isn’t a COI tracking platform — it’s a prequal intake tool attached to a finance product.
What Billy Does Differently
Billy’s prequalification tool is one part of a complete vendor compliance platform. The prequal form isn’t a standalone intake — it’s the beginning of a continuous compliance record that includes:
- Live COI tracking: The COI submitted at prequal is the start of ongoing monitoring — Billy tracks expiration dates and sends renewal outreach automatically
- AI endorsement review: Billy’s AI Review Assistant reviews submitted COIs and endorsements against your contract requirements — not just whether a COI was submitted
- ERP sync: Approved vendor status flows to Procore, Autodesk, Vista, JD Edwards, CMiC, and Sage 300 without re-entry
- Annual renewal: Billy automatically re-engages subs each year for prequal renewal — no calendar reminders, no manual outreach
- Custom forms: You can collect any document type alongside the standard prequal — MSAs, lien waivers, W9s, business licenses, safety agreements
- Managed Services option: Licensed insurance professionals handle compliance review alongside the software for GCs who need expert review capacity

Who Should Use Which Platform
Constrafor is a better fit if…
You want a lightweight prequal tool without ongoing compliance management, you value a universal form that reduces burden on your subs, or you’re primarily interested in Constrafor’s construction finance products.
Billy is a better fit if…
Prequal is the beginning of an ongoing compliance relationship for you, you need COI tracking and endorsement verification connected to the same workflow, or you’re running Procore, Autodesk, or another ERP that needs compliance sync.
The honest version: Constrafor and Billy aren’t really competing for the same use case. Constrafor solves the “standardize prequal intake” problem. Billy solves the “manage vendor compliance from prequal through warranty” problem. If you need both a universal intake mechanism and ongoing compliance management, you’d use them differently.
For GCs who’ve compared ISNetworld and Avetta and rejected them for their cost structure, Billy is often the next evaluation. If you’re coming from Constrafor specifically because you need more than intake, Billy is worth a look.
