Avalara is a software solution that automates tax compliance for retailers, helping businesses track what they owe and file taxes.

CommentSold purchases Avalara accounts for all businesses, and our integration simplifies sales tax calculations for all 50 states. Avalara stores this tax information for you to review and pay, or remit, these taxes. It also accounts for sales tax on returned items. Avalara will also file and send payment to the necessary states for an additional fee.

We recommend you set up Avalara as soon as possible. Tax codes will automatically populate on any items added once you have set this up. You'll need to manually assign tax codes to any product created before you set Avalara up. 

  Note: While Avalara can help you collect and remit taxes, we recommend that you work with a tax professional. CommentSold cannot give tax advice.

How Avalara Benefits Your Business


  • Have Avalara manage sales tax rules across multiple regions (e.g., states, counties, etc.).

Step 1: Create Avalara Account Step 2: Set Avalara Password

  1. Select Setup in the side menu of your CommentSold dashboard.
  2. Select Taxes in the menu at the top of the page.

  Note: CommentSold will automatically populate the Set Avalara API Keys and Set Avalara Company fields. You do not need to change or update either of these fields.

Configure Your Avalara Account


Once you've created your Avalara account, you'll need to confirm where you collect taxes. You'll also need to grab your default product code from Avalara and add it to CommentSold.

Step 1: Manage Tax Collection Settings in Avalara Step 2: Configure in CommentSold

Your shop's city, county, and state will have automatically populated in Avalara as your region for collecting tax during the account creation process. You can add additional regions if necessary.

  1. Log in to your Avalara account.
  2. Select Settings at the top of the page.
  3. Select Where you collect tax from the options listed.
  4. Confirm the correct region for tax collection. If you collect taxes elsewhere, add those locations by selecting the + Add to where you collect sales and use tax link.

If you reach the nexus threshold for another state (i.e., you have now generated enough sales in that state to pay sales tax), you will need to add that state as a location.

Don't worry—Avalara tracks these amounts and will let you know via your dashboard if there is a state you need to add. You can add it by selecting  + Add to where you collect sales and use tax at the top of the Where you collect tax page. Learn more about adding new states and regions here.
