Your place is saved and the Profit Check worksheet is ready to download. We’ll contact you when a suitable alpha place is available. Joining the waitlist doesn’t create a product account.
The launch date and pricing haven’t been set. Alpha invitations will go out in stages, with supported workflows and any costs explained before you accept. The waitlist is free.
Import and migration are part of alpha planning. Tools, formats, and field coverage are still being decided. We’ll confirm what works for your records before inviting you to move them.
