Three people end up here: a contractor working out what Sealinn does with a certificate, a subcontractor who has been sent a link and wants to know whether it is real before they upload anything, and the insurance agent that subcontractor forwarded it to.
If you were sent an upload link
- You got a link asking for your insuranceA contractor you work for uses Sealinn to keep track of subcontractor insurance certificates. If you got an email with an upload link, this page explains what it is — including how to check it is real.
- Asking your agent for a certificate of insuranceWritten for the subcontractor. If a general contractor asked for a certificate and turned down the one you sent, this is what they were actually asking for — and how to ask your agent so it arrives right the first time.
If you are the contractor
The product pages answer the two questions that come up before anything else — how a certificate gets read, and what actually gets checked against your requirements. Start at what Sealinn does, or go straight to how Sealinn reads a certificate.
For the insurance itself rather than the software — what a clause means, what to require, what to do when a certificate lapses mid-job — the COI terms and guides cover it.
- Getting startedFour steps, and the order matters more than any of them. Requirements first — otherwise the certificates you collect this week are measured against nothing.
- Setting your requirementsA requirement set is the rule every arriving document is measured against. Here is what each part of it actually does, and the two places it behaves in a way the form does not show you.
- Importing your subcontractor listIf the list already exists in a sheet, do not retype it. Here are the column names that map on their own, and what the preview screen is and is not promising.
- Reviewing a flagged certificateTwo completely different problems arrive on the same screen. Telling them apart is most of the skill, and the buttons mean different things depending on which one you are looking at.
- Reports and exportsFour reports for the question somebody is asking you, an audit log for the question somebody is asking about you, your subcontractor list as a file, and a bulk download for the day you want everything.
- Roles and permissionsFour roles you can hand out, and the useful decisions are two: who may approve a document, and who may change the rule it is approved against. Those are deliberately not the same person.
- Projects and per-job requirementsA project is not a folder. It is the unit that lets one job carry a stricter rule than the rest of your book, and the unit somebody else asks you about.
- The audit logEvery decision anybody made, with a name and a timestamp. Here is what lands in it, how to find the entry you want, and the limitation to know before you go looking.
- Custom documents and custom checksTwo things you define yourself: a document type beyond the four built in, and a check written in your own words that the reader evaluates on every arriving document.
- Plans and limitsTwo numbers decide your plan: how many subcontractors you track and how many people you have. Here is what each one counts, and what the app does when you reach it.
- SpreadsheetsA grid you build yourself, for the things a compliance product has no field for — and a way to attach a file to it that turns into a tracked document, if you tell it to.
If you are the insurance agent
Your client was asked for a certificate and forwarded it to you. There is no agent login to create and nothing to sign up for — this explains what the contractor is actually checking, so you can send the right thing the first time.
Ask a person
There is no ticket portal and no chatbot. Email hello@sealinn.com and a person reads it. If you are inside the app, the Support link in the sidebar does the same thing and attaches the page you were on, which usually saves a round trip.
