CoiLoop vs ISNetworld

The focused COI tracker for building GCs who do not need an industrial safety prequalification network, and do not want to push fees onto their subs.

Start freeSee pricing

ISNetworld (ISN) is a heavyweight contractor and supplier prequalification network, strongest in oil and gas, utilities, and heavy industrial, where facility operators run strict safety programs. It does far more than COI tracking: safety statistics, training, OSHA logs, financial review, and qualification across a network of tens of thousands of contractors.

If that is the problem you have, ISN is built for it. But it comes with weight and cost that do not fit most building general contractors. Subcontractors typically pay an annual subscription, often several hundred to a few thousand dollars per year, plus a setup fee, just to be in the network, and the platform is far broader than collecting and checking certificates.

CoiLoop does one job well for the GC who just needs subcontractor insurance handled: collect COIs and W-9s through a no-login link, have AI read each certificate, and get warned before anything expires. It is free to start, the GC controls it, and your subs never pay a fee to upload a document.

Why GCs pick CoiLoop

  • Your subs upload for free through a magic link instead of paying hundreds per year to join a network.
  • Focused purely on COI and W-9 tracking, so there is nothing to configure beyond your requirements.
  • Free to start and controlled by you, not priced and scoped for industrial supply-chain compliance.
  • AI reads each certificate and you confirm, with setup measured in minutes rather than an onboarding project.

Where ISNetworld may fit better

We would rather be honest than oversell. ISNetworld can be the better choice when:

  • You operate in oil and gas, utilities, or heavy industrial with strict OSHA-style safety programs.
  • You need full prequalification: safety records, training, EMR, OSHA logs, and financial review, not just COIs.
  • You require a large shared contractor network with managed, credentialed review.

Frequently asked questions

Is CoiLoop an alternative to ISNetworld?

For COI tracking specifically, yes. CoiLoop collects, AI-reads, and tracks subcontractor certificates and W-9s for general contractors. ISNetworld is a much broader prequalification network for industrial supply chains, so if all you need is insurance tracking, CoiLoop is the lighter and cheaper fit.

Do my subs have to pay to use CoiLoop like they do with ISN?

No. Subcontractors upload their documents for free through a no-login link. There is no membership fee or setup charge pushed onto your subs, which removes a common point of friction and pushback.

Does CoiLoop do safety prequalification like ISNetworld?

No, and we are clear about that. CoiLoop focuses on collecting and tracking COIs and W-9s. It does not manage safety statistics, training, or OSHA prequalification. If you need those, an industrial prequalification platform is the right tool.
