Plans
Every plan seals every document.
The seal, the certificate of completion and the audit trail are not a premium add-on — they are what CoreSign is for. Plans differ by how many documents you send, and by branding, API access and webhooks.

Questions people ask before choosing
- Does a signer need to pay, or create an account?
- No, and they never will. Plans cover sending. Receiving and signing a document is always free and needs no account.
- What counts as one document?
- One document sent for signature, however many people sign it. A contract going to four signers is one document, not four.
- Do the seal and certificate depend on my plan?
- No. A document signed on the Free plan is sealed identically to one signed on Business. It would be a strange product that made the evidence weaker for people paying less.
- What happens to my documents if I stop paying?
- Documents you have already completed remain yours. Download the signed file, its certificate and its sealed record when signing completes and keep your own copies, rather than relying on an account you may not keep. With the sealed record, the checker we publish can check the seal on your own computer. That checker comes from us, so we do not describe verification as independent of us.
- What do API access and webhooks do?
- API access, on Pro and Business, lets your own software prepare documents, follow their progress and download the finished records. Sending is always done by a signed-in person: a key prepares a document, and you send it from your account. Webhooks, on Business, tell a web address you choose when a document is sent, signed, completed, declined or withdrawn, usually within about a minute. The API reference
