Odoo Sign Module Tutorial: Complete Guide to Electronic Signatures in Odoo
If your business still prints contracts, emails PDFs back and forth, or manually tracks who has signed an agreement, Odoo Sign can significantly simplify the process.
Odoo Sign is an electronic-signature application that lets businesses upload PDFs, add signature and information fields, send documents to customers or employees, track signing status and retain completed documents inside the Odoo ecosystem. Odoo documentation confirms that Sign supports electronic-signature workflows for businesses operating in the European Union and the United States, although the precise legal requirements depend on the applicable jurisdiction.
This Odoo Sign module tutorial explains how to use Sign in Odoo 17, Odoo 18 and Odoo 19, with practical implementation considerations for business owners, CTOs, IT managers and finance teams.
What Is Odoo Sign?
Odoo Sign is Odoo's built-in electronic-signature solution. Instead of downloading a contract, printing it, signing it, scanning it and emailing it back, users can complete the process digitally.
Typical documents include:
- Sales contracts
- Employment agreements
- Rental agreements
- NDAs
- Purchase agreements
- Supplier documents
- Customer onboarding forms
- Expense and finance approvals
- Internal HR documents
- Service agreements
Because Sign works within the wider Odoo environment, a company can connect its document-signing workflow with other business processes rather than maintaining a completely separate signature system.
For companies migrating to Odoo, this can be especially useful when replacing disconnected tools and spreadsheets.
Why Use Odoo Sign?
For a growing company, electronic signatures are not simply about replacing paper.
The bigger advantage is workflow automation and traceability.
With Odoo Sign, your team can:
- Upload PDF documents.
- Add signature, name, date and other fields.
- Define multiple signers.
- Control signing order.
- Create reusable templates.
- Send signature requests by email.
- Set validity dates and reminders.
- Track pending and completed signatures.
- Store signed documents within Odoo.
- Maintain traceability of the signing process.
Odoo also generates a signatory hash that helps detect changes to a signed document. Odoo's documentation describes additional evidence such as timestamps, IP information and document traceability.
Odoo Sign Tutorial: How to Send a Document for Signature
Step 1: Install Odoo Sign
Go to the Apps menu and install Sign.
Depending on your Odoo edition and deployment, Sign can work alongside applications such as Documents, Sales, CRM, HR and other business applications.
For companies planning an Odoo migration, I recommend deciding early which documents should be managed through Sign and which should remain in Documents or another dedicated document-management workflow.
Step 2: Upload a PDF
Open Sign → Documents and upload your PDF.
For a one-time document, you can prepare the PDF directly rather than creating a reusable template.
Odoo allows fields to be placed directly onto the document. Odoo's documentation describes fields such as signature, initials, text and other information fields.
Step 3: Add Signature Fields
Open the PDF and drag the required fields onto the appropriate locations.
Common fields include:
- Signature
- Initials
- Name
- Text
- Date
- Checkbox
- Role-specific information
You should assign fields to the correct signer before sending the document.
A good implementation practice is to keep templates simple and only request information that is genuinely required.
Step 4: Add Signers
When the document is ready, click Send.
Select the contacts who need to complete the document.
For example:
Customer → Sales Manager → Company Director
Odoo can also manage the order in which recipients receive the document. With signing order enabled, the next recipient receives the request after the previous signer completes their action.
Step 5: Configure Signing Options
Before sending, configure options such as:
- Signing order
- Valid-until date
- Reminder frequency
- Email message
- Additional recipients
Odoo 19 documentation provides dedicated controls for signature requests, templates, signers, signing order, validity dates and reminders.
Step 6: Send the Signature Request
Click Send.
The recipient receives the signing request and can complete the required fields electronically.
After the document has been fully signed, Odoo can provide the completed document and certificate of completion to the relevant parties.
How to Create an Odoo Sign Template
Templates are one of the most valuable features for companies that repeatedly send the same documents.
Instead of preparing a rental contract or employment agreement every time, create the document once and reuse it.
Go to Sign → Templates and create a template from your PDF.
Add:
- Signature fields
- Name fields
- Date fields
- Text fields
- Required information
- Signer roles
- Instructions
- Tags
For example, a sales contract could contain:
Customer: Customer Sales Representative: Salesperson Company: Company Representative
Your team can then send the template repeatedly without rebuilding the document every time.
Odoo Sign for Germany and Europe
For Germany-based companies, electronic-signature implementation should be considered alongside the company's wider compliance and document-retention processes.
Odoo states that its Sign application generates simple electronic signatures and references the EU eIDAS framework. Depending on the document and business process, a simple electronic signature may not be sufficient when legislation or a particular transaction requires a stronger signature type.
Therefore, don't treat every document as having the same legal requirements.
For example, your implementation may separate:
- Standard customer agreements
- Employee documentation
- Supplier contracts
- High-risk legal documents
- Documents requiring stronger identity verification
Odoo 19 also provides configuration options for additional authentication methods and digital certificates.
For German businesses, Sign should also be considered together with GDPR, document retention, access rights and accounting processes such as DATEV/SKR03, rather than as an isolated e-signature tool.
Odoo Sign for US Businesses
Odoo Sign can also support companies operating in the United States.
Odoo's documentation discusses the ESIGN Act and UETA framework and explains factors such as signer intent, consent, attribution and document retention. However, legal requirements can vary by transaction and jurisdiction, so businesses should obtain appropriate legal advice for sensitive or regulated documents.
For US businesses, common use cases include:
- Customer agreements
- Sales contracts
- Vendor agreements
- Employee documentation
- Service contracts
- Statements of work
- Approvals
Odoo Sign + Documents: A Powerful Combination
One of the strongest reasons to implement Odoo Sign as part of Odoo rather than as an isolated application is its relationship with document management.
Odoo 19 allows the Sign action to be enabled for Documents folders. This means users can work with PDFs from Documents without necessarily leaving the document-management environment.
A practical workflow can look like:
CRM → Quotation → Sales Order → Contract → Sign → Signed Document → Documents
This reduces duplicate data entry and gives management greater visibility into the process.
Odoo Sign Use Case: HighmoonRentals
One practical implementation scenario is a rental business such as HighmoonRentals.
A rental workflow may require customers to sign agreements before receiving a property, vehicle, equipment or other rental asset.
A possible Odoo workflow is:
Rental Booking → Customer → Rental Agreement → Odoo Sign → Customer Signature → Completed Agreement → Document Storage
This approach can reduce manual paperwork and make it easier for the business team to identify agreements that are still waiting for signatures.
The implementation was successfully delivered using Odoo workflows across Odoo 17, Odoo 18 and Odoo 19, demonstrating how the business process can be adapted as the Odoo platform evolves.
Odoo Sign Use Case: Rheintal Arhmaten
Another successful implementation example is Rheintal Arhmaten, implemented for a business environment with 5 customers.
The project demonstrates an important point: Odoo Sign is not only useful for large enterprises.
Smaller businesses can benefit from reusable templates, customer-specific documents, signing workflows and centralized document storage without introducing unnecessary complexity.
For a five-customer implementation, the objective is not to build an enormous workflow. The goal is to create a clean, reliable and scalable process that can grow with the company.
Odoo 17 vs Odoo 18 vs Odoo 19 Sign
The fundamental Sign workflow remains familiar across Odoo:
Prepare → Add Fields → Select Signers → Send → Sign → Store
Odoo 17 documentation already supports one-time signing, templates, reminders, signing order, tags and signatory hashes.
Odoo 18 continues these workflows and documents features including field configuration, signing order, authentication and electronic-signature validity.
Odoo 19 expands the workflow around signature requests, document envelopes, signer configuration and management of signature requests.
For companies choosing between versions, the decision should therefore consider the entire Odoo implementation, not Sign alone.
Odoo Sign Best Practices
A successful Odoo Sign implementation should follow a few principles.
1. Standardize Templates
Create reusable templates for contracts that your team sends frequently.
2. Use Roles Correctly
Define who is the customer, employee, manager or company representative.
3. Minimize Required Fields
Don't make the signing experience unnecessarily complicated.
4. Configure Reminders
Automated reminders can reduce the amount of manual follow-up required by sales and administration teams.
5. Control Access
Sensitive documents should only be available to appropriate users and groups.
6. Plan Document Retention
Define where signed documents should be stored and how long they should be retained.
7. Test Before Go-Live
Test the complete workflow with internal users before sending contracts to real customers.
Common Odoo Sign Mistakes
Avoid these implementation problems:
Using one template for everything: Different departments may require different signer roles and document fields.
Ignoring signing order: Contracts requiring sequential approval should use an explicit signing sequence.
Poor access control: Sensitive HR or financial documents should not be accessible to everyone.
Skipping compliance analysis: Electronic signatures, GDPR and document-retention requirements should be reviewed for the company's jurisdiction and document type.
Migrating documents without structure: When migrating from another ERP or document platform, plan folders, tags, permissions and historical documents before importing everything.
