In this overview, you will find everything you need to know about the account types and the meaning of the various status logos of the Engineering Toolbox Requirements Manager (ETRM).

Our Membership Models

We offer three different types of membership, two of which are subscription-based. All functions of the user interface are available in all three memberships. The subscriptions differ from the Basic membership in that you (or your group members) see no advertisements. You add the REST API to a Single or Team subscription as the ETRM API add-on.

This structure allows you to test the ETRM free of charge for an unlimited period. Subscribing to a plan is only possible after registration.

1. Basic Membership

The basic version of the Engineering Toolbox is always free to use. No credit card information is required. This model is financed by advertisements.

2. Single Subscription

The Single subscription is designed for individual users who wish to work ad-free. With this subscription, you actively support the maintenance and further development of the platform.

3. Team Subscription

The Team subscription is the professional solution for collaboration. As a team owner, you can invite customers or partners into your ad-free groups. All ETRM members who are part of an active group with you work ad-free as long as you maintain a Team subscription.

ETRM API add-on

With the ETRM API add-on you use the REST API with your own access keys. It applies to your account and requires your own active Single or Team subscription; you book it on the subscription page or under Account → API access as soon as your Single or Team subscription is active. Members of a Team group who want to use the API take out a Single subscription with ETRM API themselves. With an active API add-on, your status logo additionally shows the word API.

Understanding the Status Logo

The color of the logo in your profile indicates your current account type and whether you are benefiting from a group membership.

Special Case: Sponsoring by Teams

If your logo appears orange (#ff914d), you are in a sponsored group:

This means you are a guest in a project owned by a Team owner. Within this environment, you work ad-free, regardless of your own subscription status.

3. The transaction is processed securely via Stripe.
4. After purchase, you will be redirected back and your status will be activated immediately.
