How does the subscription work?

Choose a plan and subscribe through your dashboard. You get immediate access to all features in your plan, with monthly or annual billing.

Can I switch plans later?

To change plans or move between monthly and annual billing, contact us and we'll make the change. You can cancel at any time: the subscription stops at the end of the period you've paid for, and you keep access until then.

Is there a free trial?

Yes. A company's first subscription to this tool starts with a free 30-day trial. You enter a card at checkout, but nothing is charged until the trial ends; cancel before then and you pay nothing.

Is the tool compliant with government regulations?

Our tools follow the regulations they cover, such as the TDG Regulations and WHMIS, and we keep them up to date as those regulations change. They help you comply; they don't replace your own responsibilities, such as training, or a trained person's judgment.

How many users can access the tool?

Everyone on your company's Certigo account. A subscription covers your whole company, with no per-user fee.
