Team collaboration

We all work in groups to achieve more than we could as individuals.

All testing carried out under your personal Simply Testable account is private and can be accessed only by you.

You could share account details throughout your organisation and have everyone sign in as the same user. You could also share a mug and wash it before passing it on to your colleagues. Neither is ideal.

We let you create a team and invite your colleagues to join your team.

Everyone in your organisation signs in independently and can benefit from the resources of a shared premium company account.

Everyone in your team can easily access all tests carried out by everyone else on the team, letting you work smoothly together as you always do.
