TrustLayer is running aggressive ad campaigns right now. If you’ve searched for COI tracking software recently, you’ve seen them. Their content is polished, their interface looks modern, and their pitch is compelling. But there’s a difference between a platform that looks built for construction and one that actually is. This comparison cuts through the marketing to show where TrustLayer and Billy genuinely differ — and when each one wins.
Quick disclosure: We’re Billy. So yes, we have a perspective. We’ve tried to be fair — including sections where TrustLayer has a real edge.
Where TrustLayer and Billy Are Actually Similar
Before the differences, the honest overlap: both platforms handle automated COI collection, both offer vendor-facing submission workflows, and both integrate with Procore bi-directionally. If you’re coming from a spreadsheet or from myCOI, either platform will be a meaningful upgrade on turnaround time and workflow visibility.
The differences show up when you go deeper: how human review works, what construction-specific tooling looks like, what “integrations” actually means in practice, and what you pay for features that should be standard.

The Real Question: What Are You Actually Paying For?
TrustLayer’s pricing model separates human review from the base subscription. That means what looks like an apples-to-apples comparison often isn’t — you need to add the human review tier to get equivalent functionality to what Billy includes as standard.
For GCs evaluating both platforms, the right comparison isn’t just the headline price — it’s the price at the feature tier that actually covers your compliance requirements. When you factor in human review, ERP integrations, and managed services, Billy’s managed plan is typically competitive or less expensive for comparable coverage.
We recommend asking both platforms for a quote that includes: (1) human review on every COI, (2) bi-directional Procore sync, and (3) your ERP if you use one beyond Procore. The gap often becomes clear at that level.
