Online checkout status

Online checkout is planned, but early access can start with reviewed email requests. This keeps installation, Machine ID collection, and license generation simple while the trial videos and purchase flow are completed.

  • Trial requests start on the Download page.
  • Paid licenses can use the same Machine ID collected during first launch.
  • Feature access is confirmed before the activation key is generated.
  • Online payment can be added after the purchase flow is finalized.

Suggested feature grouping

Draft the product packaging around workflow value, not around too many tiny switches.

Evaluation First connection, documentation access, and product fit validation.
Engineering Day-to-day testing, behavior model use, monitoring, and report path.
Custom Project Customization, onboarding, direct support, or higher-value project work.
Sales Flow

Keep the customer path clear.

The page sequence should stay simple: understand product, review documentation, confirm pricing, request trial or purchase, then move to download and support.
