# Suppliers - Old DPO Design

In this section, you can manage suppliers and add new ones. To make the process more efficient, DPO offers the option to automatically assign supplier codes

||| **Already using DPO's new design?** [You can find the corresponding article here](https://help.digitalpurchaseorder.com/en/article/suppliers-12mctxs/)

### Supplier Settings 

Before creating suppliers, you can **define settings** that are automatically applied when a new supplier is created in the project. For example, you can **require an address and email address**, restrict P.O. **creation to existing suppliers to avoid duplicates, or ensure that** supplier codes are unique ([see settings below](#6-optional-automatic-supplier-code-assignment)). Simply activate the desired options by checking the corresponding boxes.

###### Add a New Supplier

1. Click on **"+ ADD NEW SUPPLIER"** to create a new entry
2. If automatic assignment is not activated, you will need to **manually enter the supplier code**
3. Then, fill in fields such as *Name, Address,* Contact Information** and **Bank Details**
4. Complete the process by clicking **"Save"**


| If you have a large list, let us know and we can import it for you. You can find the import sheet under Administration > Import—download the Chart of Accounts Import Sheet, fill in all relevant codes and names, and send the completed file to support.ap@digitalpurchaseorder.com. DPO Support will upload it for you.

###### Optional Automatic Supplier Code Assignment

You can streamline supplier management by enabling automatic supplier code generation. 

1. Go to **Administration → Suppliers** and turn on **Automatic Supplier Code**.

After enabling the feature, configure how supplier codes should be created by setting the **starting number**, choosing the **minimum code length**, and optionally defining a **prefix** (such as *SUP*). Once everything is set, click **Save** to activate automatic supplier code assignment.

| Automatically assigning supplier codes ensures consistency, prevents duplicates, and makes sure suppliers are always created with a supplier code.

###### Identifying Suppliers Without a Code
Sort suppliers by number:

1. Click the arrow to sort suppliers by number; those without a code will then appear at the top
2. This way, you can quickly identify and update missing codes

* **File Icon:** If you see this next to your supplier, it means that something has already been created for that supplier
* **Info:** Once a Top Sheet in Expenses has been created, the supplier will be added from DPO. The supplier code must be entered the first time
* **Note:** Any changes to a supplier can affect all suppliers with documents attached

**Optional: Find Suppliers Without a Code in the SESAM Export**

Suppliers without a code can also be reviewed in the **SESAM export** under **Check Issues → Warnings**. There, all suppliers without a code are displayed, allowing you to add missing codes as needed.
