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 explain today’s human-review workflow and the separate automated design that is currently unavailable. Start at what Sealinn does, or go straight to the automated reading design.
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, so the human reviewing each certificate has a consistent checklist.
- Setting your requirementsA requirement set is the checklist your authorized reviewer uses for each arriving COI. Automatic requirement checks are currently unavailable; saved non-COI settings also remain inactive.
- 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 certificateOpen the original COI, record what it says, compare it with your requirements, and document the customer decision. Automated reading and requirement checks are currently unavailable.
- 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 logSelected actions Sealinn attempted to record, with a name and timestamp where available. Here is what normally lands in it, how to find an entry, and the limitations to know before you go looking.
- Custom documents and custom checksCustom document names and COI review prompts can remain saved. New custom-document collection and automated custom-check verdicts are currently unavailable.
- Plans and limitsEvery plan carries the core evidence record. Capacity and operating leverage rise by tier. Here is what the limits count and what a plan change does.
- SpreadsheetsA grid you build yourself for facts the COI record does not cover. Only a declared certificate can be newly attached as a tracked document; generic AI file reading is unavailable.
- Webhooks and ZapierSealinn can POST to a URL you choose the moment something happens — a certificate approved, a document rejected, or a recorded expiry date nearing. Point it at Zapier or Make and the rest of your tools can react.
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.
