Why lien automation vendors exist
Lien automation vendors like Ai Lean and Late2Lien exist because FMS software left a gap. The major FMS platforms — storEDGE, SiteLink, ESS — handle lien timelines: they track days past due and flag when a unit is eligible for lien processing. What most of them don’t do is automate the full workflow: generating the required notices with correct statutory language, managing the state-specific advertising requirements, and scheduling the auction.
Ai Lean fills that gap. It connects to your FMS via API and handles the compliance pieces that your FMS skips.
The integration-layer problem
The architecture works, but it introduces a data boundary. Your delinquency state lives in the FMS. Your lien compliance state lives in Ai Lean. When something goes wrong — a notice was sent to the wrong address, an auction date needs to be pushed — you’re debugging two systems.
UnitFull builds lien automation into the same system as delinquency. The lien workflow is part of the delinquency state machine. There’s no API connection between them because they’re the same product.
The cost argument
At 5 facilities, Ai Lean runs ~$375/month (analyst estimate — no published rate card). That’s ~$4,500/year for a subscription that handles something your FMS should do natively.
UnitFull includes lien automation at no extra charge. If you’re currently paying Ai Lean or Late2Lien, that subscription goes away when you switch.
What to verify
Lien law is hyperlocal — requirements vary significantly between states. Before switching away from any lien automation provider, verify that UnitFull covers your specific states. We’ll show you the specific workflow for your state on the demo.

Common questions
UnitFull's lien automation covers the notice workflows, timing requirements, and state-specific advertising rules for all states where we have customers. Verify your specific state's coverage on the demo — lien law requirements vary significantly between states, and we'd rather you confirm coverage than assume it.
Yes. Late2Lien and Ai Lean serve the same need — automated lien processing for storage operators using FMS platforms that don't handle it natively. UnitFull builds lien automation into the platform. If you're currently paying Late2Lien, that subscription goes away when you switch to UnitFull.
The lien workflow is part of the delinquency state machine. When a unit hits the configured lien-eligible threshold, UnitFull generates the required notices, applies the state-specific timing rules, and queues them for delivery. Advertising requirements and auction scheduling are built into the same workflow — no separate system to manage.
