What Happens After You Click Send: How the E-Signature Process Works

You upload a document, add a signer, and click send. But what actually happens after that? Where does the document go? How does the signer access it? What makes the signature legally valid?

Understanding the e-signature process from start to finish helps you trust the technology and explain it to clients or partners who are new to electronic signing.

Here is exactly what happens behind the scenes when you send a document for electronic signature.

Step 1: You Upload and Prepare the Document

Before sending, you upload a PDF and place signature fields on it — signature, date, name, initials, or custom text fields. Each field is assigned to a specific signer.

The document is stored securely on the e-signature platform's servers, encrypted at rest. No one can access it except through authorized links.

If you want to see this step in action, here is a walkthrough of how to send a document for e-signature in under 2 minutes.

Step 2: The Platform Sends a Signing Invitation

When you click send, the platform generates a unique, secure link for each signer and sends them an email invitation. This email includes:

• The name of the person who sent the document (you)
• The document title
• A button or link to open and review the document

Each signer gets their own link. These links are unique — they cannot be shared or reused by someone else. The link identifies the signer and connects their actions to the audit trail.

Step 3: The Signer Opens the Document

When the signer clicks the link, the document opens in their web browser. They do not need to download an app or create an account. The document is displayed exactly as you uploaded it, with highlighted fields showing where they need to take action.

The platform logs this event in the audit trail: the signer opened the document, at what time, from what IP address, and on what device.

Step 4: The Signer Reviews and Signs

The signer scrolls through the document, reads the content, and fills in each required field:

• Signature fields — the signer types their name (converted to a signature font), draws their signature with a finger or mouse, or uploads an image of their signature
• Date fields — auto-filled with the current date, or entered manually
• Name fields — typed by the signer
• Custom fields — any additional information you requested

Each completed field is logged in the audit trail.

Step 5: The Signer Submits

Once all required fields are filled in, the signer clicks the submit button to finalize their signature. At this point:

• The signer's signature is embedded into the document
• The platform records the exact timestamp of submission
• A confirmation screen tells the signer the signing is complete
• The signer receives an email with a link to download their signed copy

The signature is now part of the document — it cannot be moved, altered, or removed without invalidating the audit trail.

Step 6: You Get Notified

The moment the signer submits, you receive an email notification that the document has been signed. If there are multiple signers, you are notified as each one completes their signature.

You can also check the status of any document in your dashboard: sent (waiting for the signer), viewed (signer opened it), or completed (all signers have signed).

Step 7: The Audit Trail Is Sealed

Every action taken on the document — from upload to the final signature — is recorded in the audit trail. A complete audit trail typically includes:

Event	Details Recorded
Document created	Timestamp, creator's account
Document sent	Timestamp, recipient email(s)
Document viewed	Timestamp, signer's IP address, device and browser
Fields completed	Timestamp per field
Document signed	Timestamp, signer's IP address, device and browser
Document downloaded	Timestamp, by whom

This audit trail is attached to the signed document permanently. If anyone ever questions whether the document was signed, when, or by whom — the audit trail is the evidence.

Step 8: Everyone Gets a Copy

After all signers have completed the process:

• You can download the fully signed document with the audit trail from your dashboard
• Each signer receives an email with a link to download their signed copy
• The document is stored securely on the platform and accessible from your account at any time

What Makes It Legally Valid?

Electronic signatures are legally valid in the United States under two primary laws:

• The ESIGN Act (federal, 2000) — establishes that electronic signatures and electronic records have the same legal standing as their paper equivalents in interstate and foreign commerce
• The Uniform Electronic Transactions Act (UETA) — adopted by 49 states plus D.C., providing the same protections at the state level

For an electronic signature to be legally enforceable, it generally needs:

1. Intent to sign — the signer took a deliberate action (clicking "Sign" or drawing a signature)
2. Consent to do business electronically — the signer agreed to use electronic signatures
3. Association — the signature is linked to the specific document
4. Record retention — the signed document is stored and accessible

The audit trail provides evidence for all four of these requirements. It proves who signed, when, on what document, and that they took a deliberate action to do so.

This post is for informational purposes only and does not constitute legal advice. Electronic signature laws vary by state and document type. Consult a legal professional to determine whether electronic signatures are appropriate for your specific use case.

Is the Process the Same on Every Platform?

The core process — upload, send, sign, audit trail — is essentially the same across all major e-signature platforms. The differences are in the user experience, pricing, and additional features.

Some platforms add complexity with approval workflows, conditional fields, or integrations. For most small businesses, the basic flow described above is all you need.

Try the Process Yourself

The best way to understand how e-signatures work is to try it. Send a document to yourself — use your own email as the signer — and walk through the entire flow from both sides. You will see exactly what your signers see.
