What "Perpetual" Means
- The version you buy keeps working forever — signing never stops because a subscription lapsed.
- Updates are free for 1 year; afterwards you can keep your version or renew updates at a discount.
Which Plan Fits?
- Basic — one team, one certificate set: automated PDF + code signing and the full eSign portal.
- Pro — agencies or IT teams signing for up to 5 clients/departments, each isolated with its own token and folders.
- Advance — unlimited tenants for service providers.
- Enterprise — unlimited tenants plus dedicated support; contact us for volume or OEM terms.
