Avetta vs ISNetworld: What Actually Differs for Subcontractors

If you work as a subcontractor across multiple industries, you've probably been told to get on both ISNetworld and Avetta. They look similar from the outside — both are contractor prequalification platforms, both charge annual fees, both require documents and questionnaires. But the differences matter when you're deciding where to spend time, money, and attention.

This guide breaks down the real differences: market position, document requirements, grading systems, and total cost of maintaining both.

Ownership and Market Position

ISNetworld and Avetta are direct competitors, and they each dominate different sectors.

ISNetworld is the dominant platform in oil and gas, petrochemical, and heavy industrial markets — particularly in Texas, Alberta, and the Gulf Coast. If your clients are refineries, chemical plants, or pipeline operators, ISNetworld is almost certainly the platform they use. ISN has more than 70,000+ contractors in its network.

Avetta has stronger penetration in general construction, utilities, and manufacturing. Many Fortune 500 companies outside the energy sector use Avetta as their standard prequalification tool. If you work in commercial construction, facilities maintenance, or general manufacturing, Avetta may be as important — or more important — than ISN for your client base.

The practical implication: you may need both if you work across sectors, but neither platform is universally required. Follow your clients, not industry assumptions.

Registration and Annual Fees

Both platforms charge annual contractor subscription fees. Neither is free for the contractor — the cost model assumes that the compliance credential is valuable enough to justify the fee.

ISNetworld uses a tiered fee structure based on company size (annual revenue). The smallest tier — contractors under approximately $500,000 in annual revenue — pays roughly $1,100–$1,900 per year. Mid-size contractors typically pay $2,500–$5,500 per year, and the largest tier (Tier 5) is reported at over $5,000 per year. Fees are subject to change annually.

Avetta uses a similar range, but charges differently in some configurations: in addition to the base subscription, some Avetta implementations charge separately per client "connection." Depending on how many clients you connect with, Avetta costs can add up faster than the base fee suggests.

Document Requirements

The core documents are the same on both platforms. You'll need to submit:

  • Certificate of Insurance (ACORD 25 format)
  • Workers' Compensation documentation
  • OSHA 300 logs (summary and log, by year)
  • Experience Modification Rate (EMR) letter from your carrier

The difference is how documents are reviewed. ISNetworld uses a manual review queue through its RAVS (Review and Verification Services) process — documents go from Pending to Accepted or Rejected, reviewed by ISN staff. Avetta uses a combination of automated and human review, which can mean faster initial processing but less predictable outcomes.

One notable difference: Avetta places a stronger emphasis on EMR. Some Avetta client configurations will not approve a contractor connection at all if the EMR exceeds 1.0 — regardless of other compliance status. ISNetworld also uses EMR as a significant grading factor, but the hard cutoff behavior varies more by client.

Safety Questionnaires

Both platforms include a safety questionnaire that contractors must complete. ISN calls this RAVS — it covers 30 to 50 questions about your company's safety programs (fall protection, LOTO, confined space, hazard communication, and more). Each answer is scored by ISN reviewers and contributes to your overall grade.

Avetta has a similar questionnaire-based system. The good news: the ISN RAVS answers you develop are a strong starting point for Avetta. The bad news: you cannot copy them verbatim. Avetta's question wording differs, and some questions are structured differently. Plan to adapt rather than copy.

Grading Systems

The two platforms use fundamentally different grading models.

ISNetworld issues letter grades (A through F) that are visible simultaneously to all of your connected clients. Your ISN grade is a composite score, and all clients see the same grade — there's no separate score per client (though clients can set their own minimum requirements that affect your status with them specifically).

Avetta uses a percentage-based or color-coded status system. A key practical difference: Avetta scores can vary more independently by client. Your status with Client A may differ from your status with Client B based on client-specific configuration — more so than with ISN's composite grade model.

Cost Comparison: Maintaining Both

For a typical small subcontractor maintaining active accounts on both platforms, the annual cost is significant before any actual compliance work is done:

  • ISNetworld annual fee: $1,100–$5,000+ depending on tier
  • Avetta annual fee: $1,000–$3,000+ depending on connections
  • Consultant fees (if used): $2,000–$8,000 per platform

Total cost for a small subcontractor maintaining both platforms can reach $4,000–$15,000 per year before any work is done — and that's before accounting for internal labor time spent managing submissions, uploads, and questionnaire responses.

Self-serve tools that consolidate document management and questionnaire answers across both platforms reduce this cost significantly compared to hiring separate consultants per platform.

Which Platform Should You Focus On?

The answer is specific to your client base. The most common mistake is assuming one platform is universally required — or spending money on both when your clients only actually check one.

The practical approach: contact your top five clients and ask which platform they actively use to manage contractor compliance. Some may have an ISNetworld account they haven't logged into in months. Others may use Avetta exclusively.

One direct email to your clients — "Do you use ISNetworld or Avetta for contractor management, and do you actively review our status there?" — will tell you exactly where to focus. That single conversation is worth more than any industry assumption.

Frequently Asked Questions

Can I use the same documents for both Avetta and ISNetworld?

Yes — the core documents (COI/ACORD 25, OSHA 300 logs, EMR letter, training certifications) are accepted on both platforms. The documents are the same; the submission process and review procedures differ. You'll upload the same PDFs to each platform separately.

Do Avetta and ISNetworld share data with each other?

No. They are competing platforms and maintain completely separate systems. Your compliance status, documents, and questionnaire answers on one platform are not visible to the other. You maintain separate accounts on each.

Is ISNetworld required by law?

No. ISNetworld is a private contractor management platform. Your obligation to maintain an ISNetworld account comes from your contractual relationships with client companies who require it — not from any regulatory mandate. The same applies to Avetta.
