Introduction
Contracts, vendor agreements, and offer letters rarely stop at one signature. Usually, one party signs and then hands the document to a second person who signs to confirm or approve it. That second signature is a countersignature, and it’s a routine part of running a small business.
If you handle multi-party paperwork—as an owner, manager, HR lead, or freelancer—you need a fast way to countersign without printing, scanning, or chasing people down. This guide walks through two clear scenarios in pdfFiller: adding your signature to a document someone has already signed, and setting up a signing order in advance so signers complete the document in the right sequence. You already know your way around a PDF, so we’ll keep the steps practical and define any new terms as we go.
What does it mean to countersign a document?
A countersignature is a second signature added to a document that has already been signed by one party. It confirms, approves, or validates the first signature. Think of an employment offer: the candidate signs first, and the company representative countersigns to finalize the agreement.
Countersigning is a common practice in many everyday business situations—vendor contracts, lease agreements, purchase orders, and partnership documents all commonly require a second party to sign after the first.
How to countersign a document in pdfFiller
This section covers the first scenario: you’ve received a PDF that someone has already signed, and now you need to add your own signature. There’s no invitation to send here—you simply open the file and sign it yourself using the Sign tool in Edit & fill mode.
Step 1: Upload or open the signed document
Log in to pdfFiller and open the document you need to countersign. If it isn’t already in your account, click Add new in the left sidebar and upload it from your device, or import it from Google Drive, Dropbox, OneDrive, or Box. If the other party emailed the signed file to your pdfFiller inbox, you’ll find it under Received → Email.
Open the document in the editor to get started.
Open the signed document in the pdfFiller editor to begin countersigning.
Step 2: Locate the countersignature area
Scroll to the spot where your signature belongs. On most documents, this is a signature line, an “Approved by” field, or a space near the first party’s existing signature.
Step 3: Add your electronic signature
Make sure Edit & fill is highlighted at the top of the editor, then click the Sign tool (the pen icon) in the toolbar. A signature panel opens and displays any signatures you’ve saved.
If you’re signing for the first time, create your signature using one of three methods:
- Draw: Use your mouse, trackpad, or stylus to draw your signature.
- Type: Enter your name and pick from several styled fonts.
- Upload: Import a scanned image of your signature.
Save your signature so you can reuse it with a single click next time.
Choose a saved signature or create a new one with the Sign tool.
Step 4: Position and review your e-Signature
Click on the page where your signature should appear. Drag inside the bounding box to reposition it, and use the corner handles to resize it so it fits neatly on the signature line without overlapping the other party’s signature or nearby text.
Take a moment to review the whole document. Confirm the first party’s signature is present, your signature sits in the correct field, and any required dates or initials are in place.
Step 5: Save or share the countersigned document
When everything looks right, click the three dots next to the DONE button in the upper-right corner. From there, you can:
- Download a copy to your device.
- Email the countersigned document straight to the other party from within pdfFiller.
- Share it via a secure link.
Your countersigned file is stored automatically in your account, so you always have a copy on hand.
Save or share the countersigned document from pdfFiller.

How do you provide countersignatures before sending a document?
The second scenario flips the order around. Instead of waiting for a signed document to land in your inbox, you prepare the document yourself and control who signs and when. This is where you build a signing order—the sequence in which each person signs. Here’s how to arrange it in advance:
- Open your document and switch to Invite to sign. This is pdfFiller’s workflow for routing a document to one or more recipients for signature.
- Add your recipients. Enter the name and email address of each person who needs to sign, including yourself as the countersigner.
- Assign signature fields. Drop a signature field for each recipient. Each signer gets their own color-coded set, so it’s clear which field belongs to whom.

- Review and send. Click Review and send, confirm the recipients and order. Turn on the Set signing order toggle and arrange recipients in the sequence you want. Then dispatch the document.
Enable Set signing order to control who signs first and who countersigns.
pdfFiller notifies each signer automatically. Once the first person signs, the next signer receives their invitation—no manual follow-up needed. When you’d like a deeper look at the full process, see how to set the signing order and how to send documents for eSignature.

Countersigning an existing PDF vs. setting a signing order
Both approaches get you a countersigned document, but they suit different situations. Use this comparison to pick the right one:
|
Feature |
Countersigning an Existing PDF |
Setting a Signing Order |
| Starting point | A document already signed by another party | An unsigned document you prepare |
| Tool used | Sign tool in Edit mode | Invite to sign with Set signing order |
| Invitation needed | No—you sign it yourself | Yes—recipients are invited by email |
| Best for | Quickly signing a document sent to you | Coordinating multiple signers in advance |
| Signing sequence | Already handled—you sign last | You define the sequence upfront |
Sequential vs. parallel signing
When you invite more than one person to sign, pdfFiller gives you two routing options:
- Sequential signing sends the document to signers one at a time, in the order you set. The next person is only notified after the previous signer finishes. This is the right choice for countersigning, where one party must sign before the other approves.
- Parallel signing sends the document to everyone at once, and each person signs independently. This works well when all signers are equal and there’s no required order—like co-founders signing the same agreement.
For countersigning, sequential signing is almost always the way to go.
Best practices when countersigning documents electronically
A few habits keep your countersigned documents accurate and professional:
- Review before you sign. Confirm the first party’s signature is present and the terms match what you agreed to.
- Use Preview mode to see the document exactly as your signers will, and to confirm the signing order is correct before sending.
- Keep signatures tidy. Size your signature to fit its field without covering other text or fields.
- Set a deadline when sending for signature. An expiry date creates urgency and triggers automatic reminders.
- Save reusable templates for documents you countersign often, such as vendor contracts or offer letters, so you don’t rebuild the setup every time.
Real-world scenarios
Countersignatures come up across nearly every part of a small business:
- Employment offers: A new hire signs, and the HR lead or owner countersigns to confirm the offer.
- Vendor and supplier contracts: Your vendor signs, and you countersign to approve the agreement.
- Lease agreements: A tenant signs, and the property manager or landlord countersigns.
- Purchase orders: A buyer submits and signs, and a manager countersigns for approval.
- Partnership agreements: One partner signs, and the others countersign to finalize the terms.
Can you countersign a document electronically?
Yes. Electronic signatures are widely recognized as legally binding, and countersigning electronically follows the same standards as any other eSignature. In the United States, electronic signatures are governed by the ESIGN Act and the Uniform Electronic Transactions Act (UETA). pdfFiller supports legally binding eSignatures and complies with these frameworks.
Whether a specific countersignature is enforceable depends on the document and the circumstances, so consult a professional if you have questions about a particular agreement.

Glossary
- Countersignature: A second signature added to a document after another person has already signed it. It usually confirms, approves, or finalizes what the first party agreed to.
- Electronic Signature (eSignature): A digital way to sign a document instead of using pen and paper. You can draw, type, or upload your signature and place it right where it belongs.
- Signing Order: The sequence you set for who signs a document and when. It lets you decide, for example, that an employee signs before a manager countersigns.
- Sequential Signing: A workflow that sends a document to signers one at a time. The next person is notified only after the previous signer finishes, which is ideal for countersigning.
- Parallel Signing: A workflow that sends a document to everyone at once. Each person signs independently, without waiting for anyone else, which works well when the order does not matter.
