First, the setting needs to be enabled. Click on Settings at the top of your main order panel and this will open up the settings screen. Select Advanced on the left side of the screen. There will be an option for Allow Customer Web Account Creation. Select the setting that you want to use:

In Settings, click on Courier Information. You can specify the website alias to use for your company by clicking on the Change button. This is the website where your customers will sign up and place orders at. The website will always begin with https://www.dwaybill.com/.

When your customers go to the website, there will be an option at the top open an account.

This will display a form they need to fill out.

If you are using the setting for Yes (Approval required), the customer will need to enter in a valid email address. After they submit their information, they will get an automated email with a verification link they need to click to confirm their email address. After they click this link, they will appear at the top of the Customers list with a yellow highlight, indicating they are awaiting approval. You can double-click the customer to view their information and change any information or permissions. Clicking Save and Close will mark this customer as approved, and they can log in and place orders online.

The customer will now be displayed in your customer list and they will be able to log in and place orders online using the same website they signed up at.
