Kentico 7 Avalara Set-Up



Inside the download, add the project inside JMA.Custom to your Kentico solution. Build the project on these assemblies:

The Avalara.AvaTax.Adapter.dll is in the bin folder of the download. Add a referece to the JMA.Custom project in your Kentico site. Next, merge the remaining files and tell Kentico that the module has been installed.

File Merge

1. Please email with your Kentico build and hotfix number. JMA will send a custom build to you.

2. Merge the files in the download. In the App_Code folder, you will find a sample e-commerce module file. The code informs Kentico to go to Avalara for tax rates and recalculate items in the cart. When the order is set to complete or canceled, it is sent through JMACustomOrderInfoProvider and sent to Avalara for processing. For more info, please read this article:

For your reference, here is the code:

Adding Tax Codes

There are two types of subscriptions from Avalara, which are pro and basic. With Pro, you can group your products into taxable categories. These includes digital products, food, and etc. With basic, items are either taxable or non taxable. If you have the basic subscription, here are the setup steps:

First, go to ECommerce > Configuration > Tax Classes

Add an item called Sales Tax as shown below:


A sample Avalara code has been used, however, any code can be entered from Avalara.

Next, go to Products > Edit (pencil) > Tax Classes > Add Sales Tax:


Any item with this code will be taxable.

Shipping Tax

Add a tax class called shipping. Under code name, enter FR010100. If you are using a pro subscription, contact Avalara for the correct code. If you fail to follow this step, the default code is FR020200.

If you are using the pro subscription, determine your tax category. Then, add another tax class. You can add that class to your digital items.

Origin Address

Create AvalaraAddress.xml in the root of your website (next to web.config). Here is the schema:

<?xml version="1.0" encoding="utf-8" ?>
    <Name>CruiserWorks Motorcycle Gear LLC</Name>
    <Address>1355 Long Ferry Rd</Address>


Replace the address your info. If you want change your origin address based on a SKU, add a comma separate list in the SKUIDS column. The system does a lookup and pulls the address with a matching SKU. The SKUID is the primary key for the product in the COM_SKU table.  If you add a 0 for SKUIDS, then the address is the default address for all items.


Here is what the form fields do:


URL, Account Number, Company Code and License Key

You receive these from Avalara.

This is received from JMA with your purchase
