How to Digitally Sign Multiple PDF Files at Once

Signing two or three PDFs is easy. But what if your team has to sign 200 invoices, account statements, purchase orders or employee documents in a day?

Opening every PDF, selecting the DSC, placing the signature and saving the file takes hours. There is also a chance that some documents may remain unsigned or get saved in the wrong folder.

If you are looking for how to digitally sign multiple PDF files at once, bulk digital signature software can make the work much easier. You can select all the required PDFs, choose your DSC and sign the full batch in one go.

What Is Bulk PDF Signing?

Bulk PDF signing means signing several PDF documents together instead of opening them one by one.

You select the PDFs or choose a complete folder. After that, you select the Digital Signature Certificate, decide where the signature should appear and start the process.

The signed files are then saved in the selected output folder.

Bulk signing is useful for documents such as:

• Tax invoices
• Purchase orders
• Account statements
• Agreements
• Audit reports
• Employee letters
• Vendor documents
• Certificates
• Shipping documents
• Compliance documents

Why Is Manual PDF Signing Difficult?

Suppose your accounts team has 300 invoices ready for signing. If each invoice takes even one minute, the team may spend five hours on signing alone.

For every PDF, the user has to open the file, select the certificate, enter the DSC PIN, place the signature and save the signed copy. The same work is repeated for the next document.

Apart from the time involved, manual signing can create other problems:

• A document may be missed.
• The wrong DSC may be selected.
• The signature may appear in the wrong place.
• Signed and unsigned PDFs may get mixed.
• A file may be saved with the wrong name.
• The team may not have a clear signing record.

Bulk digital signing removes much of this repeated work.

How to Digitally Sign Multiple PDF Files at Once Using SEPFUST

SEPFUST Digital Signature Software allows you to sign multiple PDFs through a single process. It can also be connected with SAP, Oracle or a custom ERP, depending on your existing setup.

Here is how the process works.

Step 1: Connect Your DSC Token

Insert the DSC USB token into your computer.

Check that the token driver is installed and the Digital Signature Certificate is active. Once the token is connected, the available certificate can be selected in the software.

Step 2: Select the PDF Files

Open the bulk signing option in SEPFUST.

You can select multiple PDF files or choose a folder containing all the documents that need to be signed.

Before moving ahead, check the selected files once. This will help you avoid signing an incorrect or unapproved document.

Step 3: Choose the Digital Signature Certificate

Select the DSC that will be used for signing.

If more than one certificate is available, check the signer’s name and certificate details before continuing.

Step 4: Decide the Signature Position

Choose where the digital signature should appear on the PDF.

You can place it:

• On the first page
• On the last page
• On every page
• At a fixed location
• In a predefined signature box

The same position can be used for all PDFs that have a similar layout.

If the files have different page sizes or formats, it is better to create separate batches.

Step 5: Select the Output Folder

Choose a folder where the signed files will be saved.

Keep separate folders for unsigned and signed documents. It makes file handling easier and reduces confusion after the signing is complete.

Step 6: Start Bulk Signing

Start the signing process after checking the files, certificate and signature position.

SEPFUST will process the selected PDFs together. There is no need to open and sign each file manually.

Step 7: Check the Signing Result

Once the process is complete, check the status of the documents.

You can see which files were signed successfully and which ones failed. Any failed document can be checked and processed again after the issue is corrected.

How SEPFUST Digital Signature Software Helps

SEPFUST Digital Signature Cockpit is made for businesses that regularly sign a large number of PDF documents.

1 Sign Multiple PDFs Together

You can select several files or an entire folder and sign them in one run. This is useful when your team handles hundreds of invoices, reports or other documents every day.

2 Connect Signing with Your ERP

SEPFUST can be connected with SAP, Oracle or a custom ERP.

For example, once an invoice is approved and generated in the ERP, it can be sent for digital signing. The signed copy can then be saved in the required folder or used in the next process.

3 Pick Files from a Folder Automatically

The software can pick up PDFs from a predefined folder, sign them and move the signed copies to another folder.

This removes the need to upload every document manually.

4 Keep the Signature in the Same Place

The position of the signature can be set according to the document format.

If all invoices follow the same layout, the signature can appear at the same place on every invoice.

5 Track Signed and Failed Files

SEPFUST maintains the signing status of each document. Your team can check which files were signed, which are pending and which failed during processing.

6 Retain the Original File Name

Signed documents can be saved with their existing file names. A suffix can also be added to separate the signed copies.

Where Can Bulk PDF Signing Be Used?

Bulk digital signing is useful for any department that works with a large number of documents.

1 Finance and Accounts

Finance teams can sign invoices, credit notes, debit notes, account statements, payment documents and financial reports.

2 Tax and Compliance

Tax teams can use bulk signing for declarations, certificates, supporting documents, returns and compliance records.

3 Human Resources

HR teams can sign appointment letters, salary documents, employee certificates and internal policy documents.

4 Procurement

Procurement teams can sign purchase orders, vendor agreements, work orders and approval documents.

5 Legal

Legal teams can sign approved contracts, agreements, notices and other legal documents.

7 Import and Export

Import and export teams can sign invoices, declarations, shipping documents and customs-related PDFs.

Benefits of Signing Multiple PDF Files at Once

Less Repeated Work

The user does not have to open, sign and save every PDF separately.

Faster Document Processing

A complete batch can be processed together, which is helpful during billing, month-end closing or compliance deadlines.

Fewer Missed Documents

The signing status shows which files were completed and which still need attention.

Consistent Signature Placement

The digital signature can be placed at the same position across documents with a common layout.

Easier File Management

Signed and unsigned files can be stored in separate folders with clear file names.

Better Tracking

The signing log gives the team a record of completed and failed documents.

Checks to Complete Before Signing Multiple PDFs

Before starting the batch, check a few things:

• The DSC should be active.
• The USB token should be connected properly.
• The correct token driver should be installed.
• The right certificate should be selected.
• The PDFs should not be corrupted.
• Password-protected files should have the required signing permission.
• The signature should not cover any important text.
• Only approved documents should be included in the folder.
• The output folder should have enough space.

These checks can prevent avoidable signing failures.

Can Password-Protected PDFs Be Signed in Bulk?

A password-protected PDF may not allow digital signing if editing or signing permissions are restricted.

The protection can be removed only if you are authorised to do so. Once the required permission is available, the document can be added to the signing batch.

Can PDFs with Different Layouts Be Signed Together?

Yes, but the signature position needs to be checked.

A position that looks correct on an A4 invoice may not look right on a document with a different page size. If the PDFs have different layouts, create separate batches for each document type.

For example, invoices can be kept in one batch and account statements in another.

Can Bulk PDF Signing Be Automated?

Yes. SEPFUST can automate bulk PDF signing according to your document process.

For example, after invoices are approved in the ERP, the system can:

1. Pick up the approved PDFs.
2. Apply the authorised digital signature.
3. Save the signed copies in the required folder.
4. Update the signing status.
5. Send the documents for email or the next business process.

This type of setup is suitable for companies that generate a large number of documents regularly.
