Documents: Understanding and preparing merged PDF documents with merge tags and e-signatures

Learn how merged document uploads work in Sense HR, what they support, and when to use them for personal documents

Updated this week

Who this guide is for: Administrators (see access roles note)

Platform: Sense HR

Available on: All plans

Before you begin

Make sure you:

☑️ Have administrator permissions

☑️ Are working with a PDF document

☑️ Are ready to prepare the document for merge tags and, if needed, e-signature fields
☑️ Have access to a word processor or PDF editor so you can prepare the document and save it as a PDF before upload

🖊️ Access roles note:

On Professional, Elite, and Enterprise plans, organisations using Access Role Management can also allow manager-type (advanced) roles to add documents for the employees or groups they have access to.


Overview

Merged documents are uploaded PDFs used to create personalised employee documents. They are usually prepared in a word processor or PDF editor, then saved as PDFs before being uploaded to Sense HR.

They support:

  • Merge tags

  • E-signature fields

  • Employee-specific document generation

This article explains how merged documents behave in Sense HR (logic, behaviour, requirements, and limitations), what to prepare before upload, and when to use them instead of templates or standard document uploads.

For step-by-step upload instructions, see: Add a document to an employee profile

🖊️ Note:

This feature is available for personal documents only. Company documents do not support merge tags or e-signatures.


What are merge tags?

Merge tags are case-sensitive placeholders (for example, {{First name}}) that are replaced with employee data when the document is generated.

💡 To see the full list of available merge tags and copy them for your document, see:


PDF requirement

Merged documents must be uploaded as PDF files.

  • Other file types (Word, Excel, etc.) can be uploaded as standard documents, but:
    ❌ Do not support merge tags
    ❌ Do not support e-signatures


Prepare your PDF for upload

Before uploading a merged document, ensure:

  • Merge tags are correctly formatted (e.g. {{First name}})

  • Tags match exactly (including spaces and capitalisation)

  • Merge tags are placed at the end of a sentence or line

  • There is enough space for merged data to display correctly

  • Signature fields are added where required

💡 Tip:

You can copy merge tags from the document editor in templates to ensure correct formatting.


Add e-signature fields

To enable e-signatures, insert signature merge tags in your document.

Primary signatory (Signee 1)

  • {{Signature_1}} – signature

  • {{Signature_1_FullName}} – name

  • {{Signature_1_Date}} – date

Additional signatories

Repeat the same pattern using incremental numbering:

  • {{Signature_2}}, {{Signature_2_FullName}}, {{Signature_2_Date}}

  • {{Signature_3}}, and so on

You can include as many signatories as required.

Multiple signature placements

If the same person needs to sign in more than one place:

  • Repeat the same tag (for example, {{Signature_1}})

  • The system will apply the same signature in each location


What happens when you upload a merged document

When you upload a merged document via:

People > [Employee] > Documents > Add > Upload document > Upload merged document

  1. The document is processed
    • Merge tags are detected
    • Signature fields are identified

  2. A preview is generated
    • Merge tags are prepared for replacement
    • A Signature details panel appears (if signature fields exist)

  3. You set document-level access and permissions

    For each signature field:
    • Select the appropriate person (employee, manager, or named individual)
    • Optionally enforce signing order

  4. You assign document level permissions

    You configure permissions for:

    • Can view

    • Can edit

    • To be read

    You can assign these to:

    • The employee

    • Their line manager

    • Additional users

  5. The document is created
    • A personalised document is generated for the employee
    • Merge tags are replaced with real data

  6. To Do Tasks are triggered
    • E-signature fields create signing tasks automatically
    • To be read requirements To do tasks automatically

⚠️ Avoid duplicate To Do tasks

If your document includes e-signatures:

  • A signing task is already created

If you also enable To be read:

  • A second task will be created

👉 Leave To be read turned off if signatures are required


Limitations of merged documents

Merged documents:

  • Support basic merge tags only

  • Do not support advanced merge tags

  • Cannot be edited inside Sense HR after upload

  • Require PDF format


When to use merged documents vs templates

Use merged documents when:

  • You already have a formatted document (for example, a contract or letter)

  • You want to preserve exact layout and styling

  • You only need basic merge tags

  • You do not have access to document templates available on Professional, Elite, and Enterprise plans

Use templates (Settings > Documents) when:

  • You need advanced merge tags

  • You want to edit documents inside Sense HR

  • You want reusable, configurable document structures

  • You intend to assign personal documents at scale using the Doc Sender AMI agent (Elite and Enterprise plans only)


Best practice

  • Test your document with a sample employee before wider use

  • Keep layouts simple to avoid formatting issues

  • Ensure all merge tags are correctly formatted (case-sensitive)

  • Use templates if you need advanced merge tags
