Solutions for document integrity

Pick the workflow that matches your job — sealed invoices, trustworthy collection, business document management, or public verification. Each page explains the outcome, not a feature dump.

  • Invoices

    Sealed invoices recipients can verify

    Seal invoice PDFs so buyers can open a public link and confirm the file has not changed since you sealed it — then follow pay or report paths your plan already supports.

  • Document Requests

    Trustworthy document collection

    Create a structured Document Request, share a secure link, review each upload, send a response so recipients resubmit only rejected items, and confirm when every required item is done — available on Pro and above.

  • Organize & deliver

    Business document management

    Seal documents, share them with verification links, and organize what you send and receive — with Business Inbox for your workspace and Recipient Wallet for people collecting seals.

  • Public verify

    Document verification anyone can run

    Open a verification link or enter a code to confirm SHA-256 document integrity. Issuer Verified may appear when the issuer completed business verification (Know Your Business, or KYB) — identity and signatures are not checked today.

Send invoices and contracts no one can swap. Seal documents with a tamper-evident link anyone can check.
