Clickwrap vs e-signature for the terms you send every client

Most comparisons of clickwrap and e-signature split the world in two. Clickwrap is the checkbox in a signup flow or a checkout; e-signature is for enterprise deals. That leaves out the case most services companies actually live in: standard terms emailed to a named person at a client, and re-sent every time the text changes.

This page is about that case. It's a workflow comparison, not a feature list. If you want the legal background on whether a click holds up, it's on our legal-standing page.

The real difference is how the person on the other side reacts. A signature request looks like a contract, so it gets forwarded to legal and comes back with redlines. An accept page with the full text and one "I have read and agree" checkbox says the terms are standard, and most recipients treat them that way.

Today a standard DPA or NDA usually goes out one of four ways:

• A PDF attached to an email, with "please sign and return". Easy to send, hard to track, and the signed copy ends up in someone's inbox.
• An e-signature envelope. Clean record, but it invites review on paper that was never meant to be negotiated.
• A checkbox on the order form that points to terms somewhere else. Fast, but the record of what was agreed is thin.
• "We'll sort it out later." Common, and it's the one that hurts when a client's security questionnaire or a dispute asks for the signed copy.

For a 40-person agency sending the same DPA to every new client, the second option is often the default only because it's the tool already paid for.

E-signature is the right tool whenever the document is negotiated. Keep these in your e-signature tool:

• Negotiated MSAs and SOWs. If both sides' lawyers are editing the text, you want a tool built for versions, comments and signatures.
• Client-imposed paper. When a client's procurement team sends its own MSA, DPA or purchase terms, that's their contract, negotiated on their terms.
• Acts that need a formal signature. Anything that calls for a qualified or advanced electronic signature, a notary, or registration is not a click-to-accept job, and it's rarely standard commercial terms.

The working line: keep the negotiated MSA in your e-signature tool, and put everything standard somewhere built for standard terms.

An accept link fits any document you send to every client unchanged and don't expect to negotiate:

• NDAs before a pitch or a scoping call.
• DPAs and service-provider terms before you touch a client's data. For media and data businesses this is usually the document that holds up a start date.
• Service or platform terms that sit under every engagement.
• BAAs for healthcare clients. Whether HIPAA allows a BAA to be accepted electronically is covered in can a BAA be accepted electronically.
• Updates: a new sub-processor, a revised DPA, a changed fee schedule. Each one is a re-papering event across your whole client list.

If you send these to five clients a year, email and a shared folder probably work. At thirty clients, or once the terms start changing, the tracking becomes the job. Pacts for managed-service providers and the other services businesses we build for show what that looks like by segment.

Yes, when it's built properly. ESIGN, the federal law, says a contract "may not be denied legal effect, validity, or enforceability solely because an electronic signature or electronic record was used in its formation" (15 U.S.C. § 7001(a)(2)). A click on an "I agree" button is one form of electronic signature.

The statute doesn't settle every case. Courts ask whether the person had reasonable notice of the terms and took a clear affirmative act to accept them. Clicks lose when terms are buried or the business can't produce a record of the acceptance. The cases, including business-to-business ones, are collected on our legal-standing page. Whether a click fits a specific contract of yours is a question for your counsel.

Changes are where the two approaches differ most. With e-signature, updating a DPA across 60 clients means 60 new envelopes, 60 chases, and a spreadsheet of who has signed which version.

In Pacts, a new version never silently replaces the old one. When you publish a material change to a template, Pacts drafts a re-acceptance campaign covering every client contact who isn't yet on the new version. Before anything is sent you write a short note on what changed; that note is required. Prior acceptors get a re-accept email with your note, each send is recorded, and the template page shows how many have re-accepted and lets you nudge the rest. A coverage board shows, across your whole client book, who is on current terms and who isn't.

Every acceptance produces a certificate with the SHA-256 hash of the exact text accepted, which anyone holding the link can check on a public verification page.
