What Avetta is, and how it differs from ISN

The practical answer

Avetta is a supply-chain risk and contractor-prequalification network. The shape is familiar if you know ISNetworld: large clients require their contractors and suppliers to maintain a profile, the network verifies insurance, safety statistics and documentation, and the contractor pays an annual subscription for the privilege.

Avetta expanded partly by acquisition — BROWZ, a comparable network, was absorbed in 2019 — so contractors occasionally find a legacy profile they'd forgotten they had.

What suppliers submit

The categories mirror the industry standard: insurance certificates evidencing required limits and endorsements, safety statistics including OSHA 300A logs, TRIR, DART and EMR, written safety programs reviewed against a checklist, and a client-specific questionnaire covering whatever else that particular client cares about — which increasingly includes sustainability and financial-health questions alongside safety.

Cost and who pays

As with ISN, the supplier pays. Published ranges and consultant guidance through mid-2026 generally place Avetta supplier subscriptions below typical ISNetworld pricing — roughly the mid-hundreds to low thousands per year depending on employee count, client count and modules — with client-side fees charged separately. Treat any published range, including this one, as an order of magnitude and get a written quote.

Suppliers connected to multiple clients on the same network usually pay incremental fees per connection, which is the detail that surprises people whose customer list grows.

The profile lifecycle

Onboarding is the visible cost; maintenance is the recurring one. Once connected, a supplier re-files statistics annually as the OSHA 300A rolls over and the EMR letter reissues, updates certificates as policies renew, responds to questionnaire changes when a client revises requirements, and renews the subscription itself.

Because those cycles run on different calendars — insurance on policy dates, statistics on the calendar year, subscriptions on the anniversary — a supplier can be fully compliant in March and quietly non-compliant in July without anything having gone wrong. The profile does not warn you; the client does, usually at the gate.

Avetta versus ISNetworld

They compete for the same job and the practical differences are smaller than the sales conversations suggest. ISNetworld has deep entrenchment in North American refining, petrochemical and heavy industrial work. Avetta has historically been positioned more broadly across supply chains and geographies, with a stronger emphasis on supplier risk beyond pure HSE.

The choice is almost never the contractor's. Your client picked, and you comply. What is in your control is not duplicating effort: the underlying documents — certificates, 300A logs, EMR letters, written programs — are largely the same across networks, and maintaining them once in a system you own makes every network submission faster.

The annual cycle

A profile is not a one-time build. Each year the subscription renews, the OSHA 300A summary rolls forward, the EMR letter reissues, insurance certificates renew on their own schedule, and the client questionnaire may change. Suppliers who treat the profile as a project rather than a process are the ones who discover a lapsed status the week they need to mobilize.

Watch for connection creep too. Each new client that adopts the network typically adds an incremental fee, so a supplier whose customer list doubles can find the annual cost has moved well beyond the tier they originally budgeted for.

The cost that lands on your subs

If you are the hiring party weighing a network, price it from your suppliers' side too. A network fee is a real cost to every sub on your list, and small local trades feel it disproportionately — some decline to bid rather than pay it, which quietly shrinks your bidder pool and raises your prices.

That effect is hardest to see precisely because it is invisible: the subs who opt out never appear in your bid tabs to be counted. If you have adopted a network and noticed fewer small bidders than you used to get, the fee is a candidate explanation worth testing before you conclude the market tightened.
