Shopify is deprecating the legacy AvaTax for Shopify Plus integration on April 30, 2025. If you rely on this integration to manage sales tax compliance, you need to move to an alternative before that date. This post covers why the deprecation is happening, what to look for in a sales tax solution, and why now is a good time to switch to Kintsugi.
Why Shopify is Deprecating AvaTax for Shopify Plus
Shopify's decision to sunset the legacy AvaTax integration reflects its ongoing work on platform performance and user experience. Legacy integrations often lack the flexibility, scalability and modern capabilities businesses need as they grow.
As businesses grow and regulations change, tools like AvaTax have struggled to keep up, leading to issues like inaccurate calculations, hidden fees and limited support.
For merchants on Shopify Plus, this change means it's time to evaluate alternatives. With the April 30, 2025 deadline approaching, now is the time to switch to a more reliable solution like Kintsugi, the highest-rated sales tax app for Shopify, which delivers accurate tax calculation in just seven clicks and three minutes.
The Downfall of Avalara: Poor Reviews and Lack of Support
Avalara's reputation has suffered from numerous one-star reviews, which point to a pattern of poor customer support and a profit-driven approach that neglects customer satisfaction.
Common Complaints:
Hidden fees. Customers report unexpected charges and unwanted upgrades. One user shared, "They upgraded my free account to a paid plan without my consent and started charging me $897 a month despite my business being closed."
Inaccurate tax calculations. Businesses have faced months of miscalculations with little to no resolution from Avalara's support team. A customer noted, "We're multiple months into having the same type of order's tax miscalculated. I'm still fighting to get any help on it."
Non-responsive customer support. Many users highlight Avalara's lack of assistance, with one calling it a "horrible company" that "never really answers your questions."
The Profit-Over-Customer Mindset
Avalara's focus on profitability often comes at the expense of its customers. Instead of investing in the customer experience, the company appears more concerned with monetizing its user base through hidden fees and forced upgrades. That has left many businesses frustrated and looking for alternatives.
With Kintsugi, you avoid these problems. Kintsugi prioritizes transparency, accuracy and customer satisfaction, so you get good service without hidden costs.
