Paying for two prequalification platforms when you only need one? Here's exactly which network your contracting business requires — and why getting it wrong costs more than the registration fee.
Two registration fees. Two platforms to log into. Two document libraries to keep current, two sets of questionnaires, two renewal calendars. If a hiring client just told you that you need to be registered on both Avetta and ISNetworld®, you're already doing the math — and it doesn't feel good.
Here's the actual answer: it depends entirely on who your clients are, not on which platform is "better." And getting that answer wrong — in either direction — costs real money.
Both Avetta and ISNetworld® are contractor prequalification platforms. Hiring clients — operators, general contractors, manufacturers, energy companies — use them to evaluate vendors before granting site access or awarding work.
Instead of calling your references or manually reviewing a binder of safety docs, the operator logs into the platform and pulls your score. If it clears their minimum threshold, you're on the approved vendor list. If it doesn't, you're not — regardless of your track record, your crew quality, or your relationship with their project manager.
The platform you need is the one your client requires. That's the whole decision.
ISNetworld® is the dominant prequalification network in:
If you work in the energy corridor — Gulf Coast, Permian Basin, Bakken, or alongside major chemical manufacturers — ISNetworld® is likely non-negotiable. Operators like ExxonMobil, Shell, Dow, BASF, Chevron, and dozens of regional mid-majors run their contractor management through ISNetworld® and will not put you on a bid list without a valid, above-threshold profile.
ISNetworld® uses a letter-grade system (A through F) calculated from your TRIR, LTIR, EMR, training completion percentages, and document currency. The grade is live — it updates continuously — and your hiring clients see it in real time. A grade drop on a Tuesday can cost you a contract by Wednesday.
Avetta has a broader industry footprint than ISNetworld® and tends to appear in:
Avetta operates similarly — you build a profile, upload documents, complete questionnaires, and hiring clients pull your score. The specific scoring formula and document requirements vary by client within Avetta, which makes the platform more customizable but also more unpredictable when you're trying to maintain a passing score across multiple operators at once.
A 35-person mechanical contractor based in Houston bids on two distinct client types: petrochemical turnarounds (oil and gas clients using ISNetworld®) and commercial HVAC projects for large industrial facilities (GCs using Avetta).
For the turnaround work, their ISNetworld® grade is everything. Drop below a C and they're off the approved vendor list before the next outage season.
For the HVAC work, those same GCs don't care about ISNetworld® at all — they're pulling Avetta profiles. A lapsed Avetta subscription means they can't bid, regardless of how clean their ISNetworld® score is.
Both networks live on their compliance calendar. Both get managed. Neither gets ignored — because ignoring either one means losing that slice of their client base entirely.
If your client base is concentrated — all energy clients, or all commercial construction clients — you likely only need one platform. The most expensive mistake contractors make is paying for both when only one matters, then failing to maintain either one properly because the overhead is too high and the attention is split.
Before you register for anything, ask your hiring clients directly: "Which prequalification platform do you require?" Most will tell you immediately. A few run entirely proprietary systems — neither Avetta nor ISNetworld® at all.
Know your clients before you spend money on platforms they don't use.
Registration fees are visible. The real cost is invisible — it's the ongoing time and attention required to keep your profile current.
Insurance certificates expire. Safety policies need annual review dates documented. Training completions have to be logged individually, by employee name, against the specific modules each platform requires. Questionnaires get updated by operators without warning. If you miss a renewal or a new requirement, your grade drops before you know it happened.
This is where most small and mid-size contractors lose ground. Not because they're non-compliant in practice — but because they don't have someone watching the platform consistently.
EHS Inc. manages ISNetworld®, Avetta, and Veriforce profiles as a core service — so our clients aren't dependent on remembering every renewal date, questionnaire update, or training threshold on their own. We also build and maintain the written safety programs that underpin all three platforms. One engagement, all three networks, no compliance gaps.
