Limitations of Avalara Integration

There are currently some limitations to bear in mind when using the Avalara integration. Some of these are limitations of Avalara's service, some are design choices made by Zuora, and others are features that are currently in development.

This feature is in Limited Availability. If you wish to have access to the feature, submit a request at Zuora Global Support

Avalara Service Limitations

Tax exemption ignored when using inclusive tax mode

The Avalara integration does not currently account for customers who are tax exempt when invoicing for charges that use the inclusive tax mode. If a taxable product rate plan charge is set to inclusive mode, all customers who are invoiced for this charge will pay the tax inclusive price, regardless of whether they are tax exempt or not.

Maximum of 15,000 invoice items per invoice

A maximum of 15,000 Avalara relevant invoice items are allowed on an invoice. If an invoice contains more than 15,000 items and is sent to Avalara, the tax calculation request will fail and an error will be returned.

Submit a request at Zuora Global Support if you require additional assistance.

Invalid Addresses in U.S. Territories Will Not Return Tax Details

If an address is passed to Avalara with an invalid address in a U.S. territory, Avalara will not return tax details for the bill run. The error will result in blank cells where there would normally be tax details in the Avalara AvaTax Admin Console.

Zuora recommends correcting all invalid addresses whenever possible, but suggests two alternatives to continue the bill run to completion:

  • Remove any invalid street address and only use the city, state, and postal code, or
  • Enter General Delivery in the Address 2 field


See Manage Customer Account for more information on how to update contact information.

Zuora Limitations

Taxes calculated for draft invoices and posted invoices

When creating or posting invoices, the tax rate on invoice date is applied to all charges. 

Possible inconsistency between tax amounts on draft and posted invoices

If tax conditions change during the period between the creation of a draft invoice and a posted invoice, the tax amounts on the two invoices may be inconsistent. For example, if the SoldTo contact address of an invoice is modified or the tax rules in Avalara are updated after a draft invoice is created and before an invoice is posted, the tax amounts on the two invoices may be different. The same inconsistency may occur when a (negative) credit invoice item is created to return funds to the customer, as the tax conditions may have changed since the original invoice item was created.

Unposting, Re-posting and Canceling Invoices

Cancel posted invoice is not supported

We recommend that you do not use Avalara Integration to cancel posted invoices. If you cancel a posted invoice, you must also manually cancel the corresponding document in Avalara. Although Zuora runs a scheduled job to clean up data synchronized between Avalara and Zuora, in most cases, you need to perform cancel the document yourself manually in order to avoid data inconsistencies. The only way to conclusively avoid data inconsistencies between Zuora and Avalara is to disable Cancel Posted Invoices.

See Configure your Tenant Profile and Permissions for information on how to disable the Cancel Posted Invoices permission.

Re-posted invoices do not have tax recalculated by Avalara
Posting an invoice for the first time stores the calculated tax information on Avalara's servers. If you un-post an invoice that contains an Avalara calculated tax, change the invoice in some way, and then post the invoice again, tax will not be re-calculated by Avalara. The tax calculated for the original posted invoice will remain on Avalara's servers.

For Avalara to calculate the new tax on a re-posted invoice, Zuora recommends that you cancel the posted invoice, cancel the draft invoice, and then regenerate the invoice. By following this procedure, a new invoice number is associated with the re-posted invoice. Avalara will recognize the new invoice number as a new invoice.

Known Issues

Draft amendment previews in Zuora UI
Taxes on previews of draft amendments in the Zuora UI is not yet implemented. The value displayed for Tax is always 0.00. This issue only happens when the draft amendment preview is viewed in the Zuora UI.​


Calls using the amend API with the preview option enabled return the correct values.

Draft subscription previews in the Zuora application show incorrect taxes
Previews of draft subscriptions in the Zuora application show incorrect tax values when the following conditions are true:

  • The subscription contains at least one taxable rate plan charge that uses the inclusive tax mode.
  • The draft subscription preview is viewed in the Zuora application.

C​​alls to the subscribe API with the preview option enabled return the correct values.
