Southeastern Freight Lines, abbreviated as SEFL, is a privately owned American LTL trucking company headquartered in Lexington, South Carolina. It originates service in the Southeastern and Southwestern United States and makes deliveries throughout the United States, Canada, and Mexico. A network of service partners is used for transportation to areas outside of its service area. SEFL is the 11th largest American LTL carrier with a revenue of over $1 billion. If you don’t have a Southeastern Freight Lines account number, contact them at 803-794-7300.

Requirements

  • WooCommerce 6.4 or newer.
  • A Southeastern Freight Lines (SEFL) account number..
  • Your sefl.com username and password.
  • Customer Address, the address on your Southeastern Freight Lines account.
  • A API key from Eniture Technology.

How do I get an SEFL account number?

Call SEFL at 803-794-7300.

Where do I find my sefl.com username and password?

Contact SEFL customer service (803-794-7300) or request a username and password online.

How do I get a API key for the plugin?

You must register your installation of the plugin, regardless of whether you are taking advantage of the trial period or purchased a API key outright. At the conclusion of the registration process an email will be sent to you that will include the API key. You can also login to eniture.com using the username and password you created during the registration process and retrieve the API key from the My API keys tab.

How do I change my plugin API key from the trial version to one of the paid subscriptions?

Login to eniture.com and navigate to the My API keys tab. There you will be able to manage the licensing of all of your Eniture Technology plugins. Refer to the Documentation tab on this page for more thorough instructions.

How do I install the plugin on another website?

The plugin has a single site API key. To use it on another website you will need to purchase an additional API key. If you want to change the website with which the plugin is registered, login to eniture.com and navigate to the My API keys tab. There you will be able to change the domain name that is associated with the API key.

Do I have to purchase a second API key for my staging or development site?

No. Each API key allows you to identify one domain for your production environment and one domain for your staging or development environment. The rate estimates returned in the staging environment will have the word “Sandbox” appended to them.

Why isn’t the plugin working on my other website?

If you can successfully test your credentials from the Connection page (WooCommerce > Settings > SEFL > Connections) then you have one or more of the following licensing issues: 1) You are using the API key on more than one domain. The API keys are for single sites. You will need to purchase an additional API key. 2) Your trial period has expired. 3) Your current API key has expired and we have been unable to process your form of payment to renew it. Login to eniture.com and go to the My API keys tab to resolve any of these issues.

Why are the shipment charges I received on the invoice from Southeastern Freight Lines (SEFL) different than what was quoted by the app?

Common reasons include a difference in the quoted versus billed shipment parameters (weight, dimensions, freight class), or additional services (such as residential delivery) were required. Compare the details of the invoice to the shipping settings on the products included in the shipment. Consider making changes as needed. Remember that the weight of the packing materials is included in the billable weight for the shipment. If you are unable to reconcile the differences call SEFL customer service (803-794-7300) for assistance.

Why do I sometimes get a message that a shipping rate estimate couldn’t be provided?

There are several possibilities:

The most common reason is that one or more of the products in the shopping cart did not have its shipment parameters (weight, dimensions, freight class) adequately populated. Check the settings for the products on the order and make corrections as necessary.

1) The city entered for the shipping address may not be valid for the postal code entered. A valid City+State+Postal Code combination is required to retrieve a rate estimate. Contact us by phone (404-369-0680) or email (support@eniture.com) to inquire about Address Validation solutions for this problem.

2) Your shipment exceeded constraining parameters of SEFL’s web service.

3) The SEFL web service isn’t operational.

4) Your SEFL account has been suspended or cancelled.

5) There is an issue with the Eniture Technology servers.

6) Your subscription to the application has expired because payment could not be processed.

7) There is an issue your server.

How do I determine the freight class for my product(s)?

The easiest thing to do is to contact your Southeastern Freight Lines representative and ask for assistance. However, the official source is the National Motor Freight Classification (NMFC) directory maintained by the National Motor Freight Transportation Agency (NMFTA.org). You can purchase a hard copy of the directory or obtain an online subscription to it from their web site.

How does the density calculator work?

The density calculator will calculate a freight class by performing a calculation using the product weight and dimensions as inputs. In most cases the returned freight class will match the product’s (commodity’s) freight class as recorded in the National Motor Freight Classification (NMFC) directory. However, this is not always true and in the event there are differences, the freight class recorded in the National Motor Freight Classification (NMFC) directory takes precedence. An incorrectly identified freight class can result in unexpected shipping charges and even fees. You are solely responsible for accurately identifying the correct freight class for your products. If you need help doing this, contact your Southeastern Freight Lines Freight representative for assistance.
