Read document

The document with the deadline appears in the inbox. Open it and read it.

Select signature

Place your signature in the correct spot and adjust the size. You can either upload your signature once or draw it directly with your finger.

Examine and accept

You see the document and your signature one last time in the overview before it becomes binding.

Confirm signature

Depending on the type of signature you choose, you confirm with your signature and acceptance or with your SwissID. After that, the signature is recorded – if there are multiple parties involved, you can see who is still waiting.

Upload document

Start in "My digital mail" via New → Get signatures and upload your PDF.

Specify recipients

Specify who needs to sign and who only receives a copy. You can also sign yourself and specify the order of signers for multiple recipients.

Select and pay for your signature type

Choose how binding your signature should be and pay directly in the app – privately or on a company account.

You can see at any time how many signatures have been received and when they are due.
