# Signature invitation

Settings for digital signing on sales orders: SMS and email texts, the link's validity and automatic handling on expiry.

This page describes the settings for digital signing on sales orders. When the feature is enabled, the system sends the customer an invitation via SMS and/or email with a link to sign the document digitally. Once the customer has signed, a confirmation is sent, and the signed document can be sent as a receipt. The settings here control the texts in the messages sent as well as how long the signature link is valid.

The feature requires that the setting **Support signature feature** is turned on at the sales order level. This can only be changed by an administrator.

In the texts you can use a number of placeholders that are filled in automatically when sending: **{Url}** inserts the signing link, **{CustomerFullName}** inserts the customer's full name, and **{SalesOrderIdentifier}** inserts the sales order's number.

## How to find the setting

Open the hamburger menu in the top left corner and select **Financial**. Then go to **Setup** and **Settings**, and navigate to the category **Financial**, then **Sales Order** and on to **Signature Invitation**.

## Invitation to the customer

### Signature invitation SMS text

**Signature invitation SMS text:** The text in the SMS the customer receives with the invitation to sign. The default text is "Please sign the document at: {Url}". Remember to include **{Url}**, so the customer gets the actual signing link.

### Signature invitation email subject

**Signature invitation email subject:** The subject field in the email the customer receives with the invitation. The default is "Signature invitation for {SalesOrderIdentifier}".

### Signature invitation email body

**Signature invitation email body:** The actual text in the invitation email. The default text contains a greeting, the link **{Url}** itself and a note that the link expires.

## The link's validity

### Signature link expiration (days)

**Signature link expiration (days):** The number of days the signature link is valid, from when it is sent to the customer. The default is 2 days. If the value is set to 0 or below, the system automatically uses 2 days.

### Auto-approve on expiry

**Auto-approve on expiry:** Determines what happens when a signature link expires without the customer having signed. When it is turned **on**, the invitation is approved automatically on expiry. When it is turned **off** (default), the invitation is not approved automatically but is deactivated on expiry.

## Confirmation to the customer

### Confirmation email subject

**Confirmation email subject:** The subject field in the confirmation email that is sent once the customer has signed. The default is "Signature confirmation for {SalesOrderIdentifier}".

### Confirmation email body

**Confirmation email body:** The actual text in the confirmation email that is sent once the customer has signed the document.

## Receipt with signed document

### Receipt of signature email subject

**Receipt of signature email subject:** The subject field in the email that is sent with the signed document attached. The default is "Receipt of signature for {SalesOrderIdentifier}".

### Receipt of signature email body

**Receipt of signature email body:** The actual text in the receipt email, where the signed document is attached.
