One product. Four sizes.
Every plan is the whole of Sealinn — the AI reading, the compliance checks, the reminders, the upload portal, the audit log. What you pay for is headroom: how many subcontractors you track and how many people can work on them.

Text reminders are the one thing that is not on every plan — each message costs us money to send, so they start on Growth. Everything else here is on every plan, including Free. You move up when you outgrow the subcontractor or seat count, never to unlock a feature.
What you’re comparing this to
For most crews the alternative is a spreadsheet, and it costs nothing to buy. That is a real advantage and it is worth saying plainly instead of pretending the incumbent has no merit.
What a price comparison misses is that only one of these costs arrives as an invoice. The others are the time somebody spends re-keying certificates and asking again for the renewal, and whatever sits behind a certificate that nobody read closely. Neither of those gets smaller because the software was free.
There is no savings calculator on this page. It would need figures about your operation that we would have to make up, and a made-up input gives you a made-up answer. Two pages take it further, and neither is a pitch:
Pricing questions
Is the free plan really free?

Do I pay per certificate or per upload?
Any setup fees or surprise charges?
Can I switch plans later?
