ISNetworld vs Avetta is usually the wrong question to start with, and adding Veriforce to the comparison does not change that. The prequalification network that pays off is the one your target client already requires. None of the three gets you work on its own. Each one is a gate a specific hiring client has put in front of its contractor list, and the subscription only earns its cost if that client's work is worth more than the fees, the admin time and the audit effort. This guide sets out how each network works, what they typically ask for, how to estimate the real cost, and how to decide before you pay.
Disclosure: Plan@Job is not affiliated with ISN, Avetta or Veriforce, and we receive nothing from any of them. We also do not publish their prices here. All three quote by company size, scope of work and the number of hiring clients you connect to, and they revise those prices. Any figure we printed would be out of date or wrong for your business. As of November 2026, the honest advice is to get a written quote from the network your client names, dated, before you sign.
The short answer: follow the client mandate
Large owners in oil and gas, utilities, chemicals, manufacturing and facilities management outsource contractor vetting to these platforms. When an owner adopts one, its procurement team will usually tell you something like "you must be active and compliant in [network] before we can issue a PO."
That sentence decides the purchase. Ask these questions in order:
- Which network does this specific client require, in writing?
- Which client sites or business units does that apply to? Some owners use different networks in different divisions.
- What grade or status do they need: just a subscription, or a passing grade on their own criteria?
- What is the realistic annual value of work from this client if you get approved?
- Do other clients you already serve, or are bidding, use the same network?
If you cannot get a straight answer to question one, do not buy anything yet. Buying a network speculatively, hoping it makes you visible to owners, rarely works. Owners use these systems to check contractors they already intend to use, not to browse for new ones.
How ISNetworld, Avetta and Veriforce differ
The three overlap a lot. All of them collect your safety program documents, insurance, injury and illness data, and company information, then check it against each hiring client's requirements. The differences are in where they are strongest and what extra modules they lean on.
ISNetworld (ISN)
ISNetworld is widely used by large owners in energy, chemicals, construction and manufacturing across North America. Contractors typically complete:
- A management system questionnaire covering your safety program and history
- OSHA injury and illness data drawn from your OSHA 300 and 300A logs
- Your experience modification rate (EMR) from your workers' compensation carrier
- Written safety program documents, reviewed against each client's requirements (often called RAVS reviews)
- Certificates of insurance meeting each client's limits
Each hiring client sets its own grading, so you can be green for one owner and yellow or red for another on the same data. Budget time for program rewrites, not just uploads.
Avetta
Avetta grew out of the PICS platform and serves a broad mix of owners, including energy, utilities, real estate, facilities and some large retailers. The structure is similar: a prequalification questionnaire, safety statistics, insurance and document review, with client-specific requirements layered on top.
Avetta membership is commonly tiered by the level of service a client requires, and some clients ask for added services such as document review or employee qualification tracking. Check exactly which tier your client specifies, because paying for a lower tier than the client needs leaves you non-compliant, and paying for a higher one wastes money.
Veriforce
Veriforce is strongest in pipeline, gas distribution and energy work, where operator qualification (OQ) matters. Under the federal pipeline safety rules in 49 CFR Parts 192 and 195, pipeline operators must ensure that individuals performing covered tasks are qualified. Veriforce is widely used to manage that qualification evidence alongside contractor prequalification.
If you do pipeline or utility work, Veriforce costs can be driven as much by individual worker qualifications and evaluations as by the company subscription. Count your people, not just your business.
Working out what it really costs
The subscription is the visible number. It is rarely the biggest one. Before you commit, build a simple first-year cost for the network your client requires.
Direct costs
- Annual subscription or membership, based on your company size and number of connected clients
- Add-on modules a client demands, such as document review or worker qualification tracking
- Per-worker training or evaluation fees, where relevant
- Any audit or site visit fees a client requires
Hidden costs
- Admin time. Someone in your office will spend days on the first submission and hours every month keeping it current. Price that time at a real rate.
- Program rewrites. Many contractors fail first review because their written safety programs are generic. Fixing them may need a consultant or a safety manager's time.
- Insurance changes. Clients can require higher limits, specific endorsements or additional insured wording. Your premium may rise.
- Renewal drift. Certificates expire, logs need posting each year and clients add new requirements. Lapse once and you can be blocked from site.
The break-even test
Set the total first-year cost against the realistic gross margin from that client's work, not the contract value. A useful rule of thumb is to ask whether one or two average jobs from that client cover the full cost. If they do, and the client has confirmed you are on their shortlist, it is usually worth it. If you would need a long run of work just to break even, push the client for a firmer commitment first.
Illustrative example (fictional): A mechanical contractor in Texas is invited to bid on maintenance shutdowns for a refinery that uses ISNetworld. The refinery confirms the requirement in writing and says approved contractors usually get repeat calls. A second prospective client, a utility, uses Veriforce for its gas crews. The contractor buys ISN now, because the refinery is a confirmed opportunity, and parks Veriforce until the utility issues an invitation to bid.
What should still be a person's decision
Prequalification paperwork is detailed and easy to get wrong. Some decisions belong with an owner or safety lead, not an office junior:
- Which clients justify a network subscription at all
- Whether your written safety programs truly reflect how your crews work, because auditors and incident investigators will compare the two
- How you report injury data and EMR, which must match your actual logs and carrier statements
- Insurance limits and endorsements, agreed with your broker
- Whether to accept a client's grading conditions or walk away
Treat prequalification as a sales cost tied to named clients. Review it once a year: which networks brought real work, which ones only brought invoices.
Where Plan@Job fits
Plan@Job is not a prequalification network, and it does not replace ISN, Avetta or Veriforce when a client mandates one. If an owner requires a network, buy the one they require.
What Plan@Job does is run the work itself. It is AI-powered project and operations management for construction and property businesses. In Plan@Job, an Operator is the contractor business managing its clients, project delivery, subcontractors and in-house operatives. You can split jobs into internal stages with scope, dates, status and costs, and mix subcontracted and in-house delivery on the project management side. The client sees the agreed overall scope, price and shared evidence, while your internal stage costs and subcontractor identities stay internal.
Plan@Job also has AI staff that work in the background. Sophie Bennett, the AI Enquiries Coordinator, checks existing job briefs for missing information and asks for clarification. Daniel Reed, the AI Operations Manager, follows up quotes and proposed dates and prepares a morning brief. Maya Collins, the AI Finance Coordinator, prepares deposit and overdue payment actions for your approval. None of them award work, set prices or move money on their own.
The point is simple: prequalification networks are a cost of access to specific owners. Your work channel should not add another compliance-network fee on top just to be considered by the clients you already have.
Plan@Job's feature launch is live in the UK. For US contractors, the US contractors page has the current reserve and waitlist route.
FAQ
Is ISNetworld or Avetta better for a small contractor?
Neither is better in general. The right one is whichever your target client requires. If you have no client asking for either, buying one speculatively is unlikely to bring work, because owners use these platforms to check contractors they already plan to hire.
Can I use one prequalification network for every client?
Only if every client accepts it. Most owners require their chosen network and will not accept another as a substitute. Some contractors end up in two or three networks because their clients are split. Review each one annually against the work it actually brought in.
Do I need Veriforce if I do not do pipeline work?
Usually not, unless a client outside pipeline work specifically requires it. Veriforce is most associated with operator qualification for covered pipeline tasks under federal pipeline safety rules, so its value is highest for gas, pipeline and utility contractors.
