About availability and your request

For request-only listings, “Pre-order request” means release interest or a project inquiry, not a purchase. The Founding Edition uses its separate paid checkout and purchase terms. Planned arrival in 2027 is a current target, not a guaranteed shipment, installation or service date. Timing, specifications, supported integrations, regional availability and pricing may change. Your request does not guarantee allocation or delivery, and you have no obligation to buy. Final details and any purchase terms will be provided separately before you decide to place a binding order. You may withdraw your request by contacting 4SI.

For software, 2027 refers to the planned product rollout associated with these offerings; existing web access is separate. Installation and Enterprise deployment are confirmed per project.
