Each hiring client sets its own requirements, and they change. This guide covers the dates that come back every year on any account. It is not legal or compliance advice. Every source was opened and checked on October 14, 2026.
A date that nobody owns is easy to miss. Below are the dates that come back every year for a contractor who has to stay current on ISNetworld (ISN), and the matching dates on Avetta and Veriforce. Each one says what it needs and where it comes from, so you can check it yourself.
1. Dates set by law
Two OSHA rules put a date on injury and illness records. They apply to employers who must keep those records. OSHA says many employers with more than 10 employees must, and that certain industries are exempt, so check OSHA’s recordkeeping page for your case.
| When | What | What the source says |
|---|---|---|
| February 1 | Post the OSHA 300A annual summary | At the end of each year you review the OSHA 300 log, summarize it on the 300A, and a company executive certifies the summary. Post it by February 1 of the next year, where employee notices are normally posted, and keep it up until April 30. (OSHA 29 CFR 1904.32) |
| March 2 | Send the 300A to OSHA online, if your establishment is covered | Establishments with 250 or more employees that must keep records, and establishments with 20 to 249 employees in the industries OSHA lists, submit the 300A by March 2 for the year before. Establishments with 100 or more employees in a second list of industries also submit the 300 log and the 301 incident reports. (OSHA 29 CFR 1904.41) |
The executive who certifies the 300A can be the owner of a sole proprietorship or partnership, an officer of the corporation, the highest ranking company official working at the establishment, or that official’s immediate supervisor.
Keep each year’s 300 log, 300A and 301 incident reports for five years after the year they cover (OSHA 29 CFR 1904.33). The 300 log has columns for each case’s employee name and job title; the 300A is a page of totals that does not name injured employees (OSHA forms package). When a network or client wants your injury numbers, upload the 300A. Upload the full log only if you are specifically asked for it, because it names your employees.
2. Dates set by each network
Each network sets its own yearly dates in its subscription terms. These are the ones the networks publish themselves.
| When | What | What the source says |
|---|---|---|
| The anniversary of your ISN activation date | Renew ISNetworld | An ISN subscription lasts one year and begins on the day ISN receives your first payment, the activation date. You renew for another year by paying the then-current annual fee on or before the anniversary of that date. A subscription that lapses may be charged a reinstatement fee. (ISN User Agreement, sections 2 and 3) |
| March 31 | Complete the Avetta annual update | Avetta says March 31 is the final date to complete the update. Suppliers are typically asked for safety performance data, regulatory documents that vary by region, and any annual forms their clients add. Missing the date marks the supplier non-compliant. Avetta lists temporary suspension from client networks among the consequences, and says the supplier is not considered compliant until the documents are submitted and reviewed. (Avetta supplier update FAQ) |
| Every 12 months from your first Avetta subscription date | Avetta renewal | The Avetta subscription renews automatically every 12 months from the date you first subscribed, unless you contact Avetta to end it before the renewal date. The renewal invoice is issued 30 days before and serves as the renewal notice. (Avetta End User Service Agreement, Attachment 1) |
| January 1 to December 31; January 31 | Veriforce subscription year and fees | A Veriforce subscription runs on the calendar year. Unless your order says otherwise, annual fees are invoiced in advance and due by January 31, and they are not prorated for part of a year. The subscription renews automatically for another year unless either side gives written notice of non-renewal at least 30 days before it ends. (Veriforce Contractor Subscription Terms) |
The Avetta FAQ page shows no publication date, and its portal steps refer to the 2025 annual update. Confirm the current steps and the date inside Avetta Connect.
Put these dates in your calendar: download the yearly dates (.ics) for Outlook, Google Calendar or Apple Calendar. It holds the OSHA 300A dates (February 1, March 2, April 30), the Avetta annual update (March 31) and the Veriforce fee and renewal-notice dates (January 31, December 1), each repeating every year with its source and reminders 14 and 3 days before, where your calendar keeps them. Dates that differ per company, like policies and renewals, are in the next section.
3. Dates that depend on you
These have no fixed calendar date. Set each one once, as a due date, so nothing lapses by accident.
- Insurance certificates. Each policy has its own expiry date. Clients check the certificate against their own limits and endorsements, so track the expiry of every policy, not the day you uploaded the file. Devon Energy’s public page, for example, lists minimum limits, an insurer rating, additional insured status and a waiver of subrogation (Devon Energy).
- The ISN questionnaire and statistics. Kinder Morgan’s contractor page says its ISNetworld questionnaire is used to collect EHS data and quarterly statistics, and that ISN’s review team checks written health and safety programs against regulatory and Kinder Morgan standards (Kinder Morgan). Ask each client how often it expects updates, and put a review date on each written program.
- Training and orientation. Clients decide what is required and how often. EQT says its contractor orientation must be documented for everyone on its premises and is required annually or when its safe work rules change (EQT). Ovintiv says its general safety orientation is retaken only when the content changes materially (Ovintiv).
- Experience modification rate (EMR) letter. If a client or network asks for it, replace it when a new rate arrives from your insurer or rating bureau.
- DOT and pipeline work. If your work is regulated by the US Department of Transportation or is on pipelines, check whether these rules apply to you: drug and alcohol testing programs (49 CFR Part 40 and Part 199) and the qualification of pipeline personnel (49 CFR Part 192, Subpart N and Part 195, Subpart G). Kinder Morgan’s page asks affected contractors for operator qualification records, and contractors doing DOT work for a drug and alcohol plan.
- Client-specific items. Every hiring client can add policies, forms and site rules on top of the shared list, and can change them. Devon Energy’s page says it may change its listed documents without notice. Check each client’s own list once a year. Twenty operators’ public requirements are summarized on the operator requirements pages.
4. How to keep ISNetworld current
A routine that does not depend on anyone’s memory:
- One list of hiring clients per network, with the network each one uses.
- One date and one document per item, linked, so a renewal is done once and counts for every client that needs it.
- A reminder to a person, not to a shared inbox, 30 days, 14 days and 3 days before each date.
- A look at the whole list every January, before the February 1, March 2 and March 31 dates.
- A written note of who owns each date, so a vacation does not stop a renewal.
- A separate user for every person who works in the account. ISN’s agreement says each user needs a unique username and password and that they may not be shared. The guide for consultants has the details for all three networks.
5. If you keep this for several contractors
Consultants who run these accounts for many contractors keep the same calendar once per contractor, and the list grows with every hiring client. The guide Managing many contractors’ ISNetworld, Avetta and Veriforce accounts covers the weekly routine, what to track for each contractor and who does what.

Requirements change. Confirm each item with your hiring clients and the network. PrequalReady is not affiliated with ISNetworld, Avetta, Veriforce or any hiring client, and their names belong to their owners.
7. Where PrequalReady fits
PrequalReady is a workspace that keeps each contractor’s hiring clients, requirement lists, documents and expiry dates in one login, ranks what needs attention first and emails reminders before your dates. It does not log in to ISNetworld, Avetta or Veriforce for you, you enter the dates yourself, and it does not judge whether your documents are acceptable. It is free during early access. See the consultant view or a 3-minute demo with a sample company.
