That is only possible with employee documents that are signed by only one person (the employee) and therefore do not require a signature placeholder. See this article for more information about the process.
It does not work for documents that require several electronic signatures (such as employment contracts in recruiting). You will need to edit your existing templates in a word processing software and insert signature placeholders. Then you will need to upload the template into Personio again.
More information on how to create document templates with signature placeholders can be found here. 

Technically, electronic signatures can be used for all documents in Personio (e.g. employment contracts, supplementary agreements, declarations of consent, etc.) See these articles to learn more about using signatures for employee documents and signatures in the offer process.
If you have any questions regarding the legal security and effect of electronic signatures, please contact a lawyer or legal advisor of your choice.
Personio merely provides the technical prerequisites and the tool for using signatures and assumes no liability.

Employees who need to sign employee documents must have a status of Active or Onboarding so that they can be selected as signatories. There also has to be a valid email address stored for them in their employee profile. It is not possible to request signatures from inactive employees.
In the recruiting area, you have the option to request digital signatures from candidates (and involved employees) for documents such as contract offers. Make sure that candidates' email addresses are stored correctly in their candidate profiles. See this article for more details on using signatures in the offer process.

You can change the order in which the signatories have to sign the document by adjusting the respective settings. Go to Settings > Documents and select the template you prefer. It should contain signature placeholders for at least two different signatories. Click on Who will sign it first? to change the order of the signatories using drag & drop. 

First, check whether the email address that is stored in the employee's or candidate's profile is correct. Employees have to be in Active or Onboarding status. Ask the signatory to check the spam folder in their email account, or to see if their inbox could possibly be full.
If you were able to identify the reason the email failed to reach its recipient, correct the issue and send the request again by clicking the button Request again that will appear once the previous signature request has expired. 

When an employee document needs to be signed by only one person and doesn't have a signature placeholder in the template, the signer can make the signature box bigger. That way, the size of the final signature can be changed.
With documents involving several signature placeholders, this is unfortunately not possible. 

For the facilitation of signatures, we work together with the Spanish company SignatureIT. The signature type offered is the advanced signature. See this article for information on legal validity.

Whether and for which documents electronic signatures are legally binding depends on the laws of your country. See this article for further information.

In the Signatures Overview page that is accessible through the Automations area, you will see how many digital signatures your monthly plan provides for and how many you have already used.
