Configuration Steps

After completing the Enablement steps, you will need to configure Nimble AMS so that it can effectively use a third-party tax service to calculate taxes wherever needed.

Please follow the steps below to configure Nimble AMS to work with Avalara AvaTax.

Nimble AMS Advanced Taxation functionality is designed to work with any third-party tax service. The stock implementation is with Avalara AvaTax but you can develop integration with other third-party tax service to replace Avalara AvaTax.

1. Create an Avalara AvaTax Account

An Account should be created with Avalara by subscribing to their product - Avalara AvaTax which is integrated with Nimble AMS to perform tax calculations. You can browse through a number of plans for Avalara AvaTax and subscribe to one which is best suited for your business. For testing and trial purposes, you can also sign up for a free trial. To create a free trial account, follow the below steps:

  1. Go to Signup page.

  2. Enter your details on that page and click Continue.

  3. Enter company details and click Next.

  4. Select the API to be used.

  5. Set your password using the email sent by Avalara.

Please reach out to Avalara directly if you have questions on their software.

Expected Result

Your trial account should now be set up. Using this account, you can test if Avalara suits your needs. The free trial is valid for 60 days, and you can later convert or upgrade it to a production account. You will probably be contacted by Avalara Sales representative to finalize the sale and pricing for your plan. 

2. Configure Page Layouts

We have added some fields which will be required to configure, manage, and use the functionality. Please add these fields to respective page layouts.

  • Entity page layout with the four new Ship From address fields - Ship from City, Ship from State, Ship from Country, Ship from Street.

  • Ship Method page layout with Tax Code and Is Taxable field.

  • Product page layout with Tax code field and Taxable checkbox.

  • Sales Tax record page layout with Status field.

  • Order page layout with External Tax ID field.

  • Order page layout with External Tax Transaction Status field. 

3. Configure the Entity

You must configure the entity or entities in Nimble AMS, with a Short Name and Ship From Address. This information will be sent to the external tax service for calculating the tax accurately. 

  • Open Entity record in Nimble AMS and make sure that Short Name and Ship From Address are added/available for all the entities that you want to set up in Avalara for tax calculation
  • Ship From Address on an entity is used to help calculate the tax accurately.
    • For Events, Nimble AMS uses the Event’s location address as the single address to calculate tax as opposed to using ship to and ship from address.

    • For Events conducted remotely like Webinars, Organization can leave the Event Location address blank and system will use Entity's Ship From Address for tax calculation.
    • For other products, Nimble AMS uses Ship From Address of the entity in conjunction with Shipping or Billing Address as the Ship To Address to calculate the tax.

Account and Shipping

If an Account does not have Shipping Address, the order processor will use Account's Billing Address for tax calculation. If Billing Address is also not provided, an error is displayed to the staff administrator on clicking the Calculate Tax button on the order processor. In CH, user has to enter one of the addresses to complete checkout.

4. Configure Named Credentials

Named Credentials are required for integration of Nimble AMS with Avalara, as Avalara is a third party system. You need to edit the default Named Credentials to add details of your Avalara Account. 

To edit the Named Credentials, follow the below steps:

  1. From Setup, enter Named Credentials in the Quick Find box, then select Named Credentials.

  2. Edit the Avalara Named Credentials "AvalaraTaxation" and populate or enter the values given below:

    • In Identity Type, ensure that Named Principal is selected.

    • In Authentication protocol, ensure that Password Authentication is selected.

    • In Username, enter the Account ID of your Avalara account. Account ID was set up in 'Step 1 - Create an Avalara AvaTax Account'.

    • In Password, enter the License key of your Avalara account. Avalara documentation to get License Key.

If you need to enter different Endpoint URL, make sure to create a new Named Credential record with the latest URL, as editing the URL is not allowed on the existing Named Credential record.

Use the newly created Named Credential record while configuring the External Sales Tax record.

5. Configure Sales Tax Record

Nimble AMS Advanced Taxation works with Internal  and External Sales Tax records to calculate Sales Taxes. You will need to create an External Sales Tax record for the third-party tax service Avalara AvaTax to perform tax calculations. You can create multiple External Sales tax records as well, to separate the GL entries, if needed. The applicable sales tax (Internal or External) will be auto assigned based on country/jurisdiction of the sales tax record and the shipping address.

  4. Click New.

  5. On the pop up, select External and click Next.

  6. In Sales Tax Name, enter the name of the sales tax you are creating.

  7. In Named Credential, enter the name of the Named Credential. If you have edited the default Named Credential in Step 4 - Configure Named Credentials above then enter the value, otherwise leave the field blank and Nimble AMS will use the default named credential, AvalaraTaxation.

  8. In Calculator Class, enter Avatax.AvalaraCallable.

  9. In Status, select Active

  10. In Entity, enter the name of the Entity for which you are creating this sales tax.

Link GL Account with Entity Used

7. Map Tax Codes to Item Codes in Avalara Portal

  2. Go to the Avalara website and login to your Association's account.
  3. Match the values to the related Item Code in Avalara using the dropdown provided in Avalara under What You Sell.
  4. There is also a spreadsheet available on the Avalara portal called "Avalara_Tax_Code_list" which can be used to understand which tax codes must be applied. See the Avalara Select Avalara Tax Codes documentation for more details.

See Adding Tax Codes for a general overview on Tax Codes.

Taxable or not?

Products and Shipping Methods where tax needs to be charged should be marked as taxable.
