Create your CLS account.

When Professional is the right fit

The Professional plan is aimed at engineers and technical teams who need more than a simple logic drawing tool. It is designed for projects where requirements need to be captured clearly, Boolean logic needs to be generated and reviewed, and the resulting behaviour needs to be checked before handover.

This page exists to explain the purpose of the Professional path before the account is created. That gives search visitors and internal reviewers a clearer landing page than a thin signup screen, while still keeping the actual account creation flow short and direct.

• Use Professional when you want the connected CLS workflow rather than a standalone diagramming step.
• Use it when validation, documentation, and engineering review matter as much as the initial logic build.
• Use it when you need one account that can carry the user from website signup into the paid CLS workspace cleanly.

How the Professional signup path works

The sequence is simple. First, the user creates a secure CLS account. Second, the email address is verified so the account can be trusted for recovery, billing, and product access. Third, CLS continues directly to the Professional Stripe checkout using the same account session.

That approach keeps billing in Stripe while CLS remains the source of truth for product access and account state. It also reduces confusion for users comparing plans, because the page explains what the Professional tier is intended to cover before they reach checkout.
