Avalara and Vertex are leading sales tax solutions for enterprise businesses, but they differ significantly. The best choice depends on your required integrations, budget, and support needs.

Sales tax can be one of the most complicated aspects of business for e-commerce and software-as-a-service companies. This is because sales tax regulations for these types of products vary from state to state (and from country to country).
Keeping up with them all can be close to impossible. That’s why a host of sales tax compliance solutions have arisen — software that aims to make your life easier by managing your sales tax obligations for you. Typically, they register your business where necessary, calculate your sales tax obligations, file your returns, and pay each tax-collecting entity, without you having to lift a finger. There are a lot of options, including purpose-built solutions for ecommerce, accountants, and enterprises.
In the world of enterprise-grade sales tax solutions, Avalara and Vertex stand above all others. These well-established products were designed with large enterprise clients in mind. Both can handle massive, international workflows.
However, each platform does have its strengths and weaknesses. It’s important to understand them before making a decision on something as important as sales tax compliance software. In this article, we’ll delve into everything you need to know about these two sales tax solution giants.

Avalara is one of the most widely used sales tax compliance platforms for large enterprises. It’s known for its incredibly comprehensive suite of tools and its global reach. Avalara was designed to simplify the complex process of tax management, and it has become popular amongst large e-commerce companies with global operations. It offers customers an end-to-end sales tax solution — from calculating taxes to filing and remitting payments — making the lives of clients easier around the world.
Avalara was designed with large enterprises and complex sales tax situations in mind. In order to accommodate these companies, Avalara has a wide range of features, including:
Additionally, Avalara has one of the most comprehensive lists of no-code integrations out there. It can easily integrate with a wide range of ERP systems, such as NetSuite and SAP; e-commerce platforms such as Shopify, Amazon, BigCommerce, Salesforce, eBay, and Etsy; and billing software such as Stripe and Recurly.
As you might expect, if they don’t have an out-of-the-box integration for an app that your company relies on on a day-to-day basis, they offer API access and support. This allows you to tailor integrations that work for your company, no matter what software you’re using.
Unfortunately, Avalara doesn't disclose pricing online. Instead, you need to book a demo with the sales team, so they can evaluate your needs and create a custom plan that works for you. Avalara’s pricing is based on a wide variety of things, including the number of transactions your business does, the jurisdictions it sells in, and the features it requires.
Avalara can handle multi-jurisdictional compliance, automate filings, and manage exemptions, which makes it an ideal choice for enterprises with complex tax obligations. In addition, if your company is expanding internationally, Avalara can help navigate the complex tax obligations created by international commerce.
Avalara is widely used software, so there are plenty of reviews on its Capterra page. Although they have 4.1 stars (out of five) and more than 300 reviews, there are some concerning things that can be gleaned from reading through comments. Many people mention that although the product is great, the customer service leaves much to be desired. Avalara is often compared to TaxJar and Anrok, too.

Vertex offers a wide range of tools designed to handle the sales tax intricacies associated with running a large-scale enterprise, such as:

Vertex can integrate with ERP platforms like SAP and Oracle, customer relationship management tools like Salesforce, e-commerce platforms like Shopify and Magento, and many other applications.
If they don’t have a pre-built, no-code integration for software that your business uses, then you can always use their API access to design a custom integration. This ensures that Vertex can be integrated into practically every single software stack out there!
As with Avalara, Vertex’s prices are not published online. You need to book a demo with them so a sales team can go through your specific needs. Similar to Avalara, Vertex’s pricing is based on transaction volumes, the specific needs of your business, and the jurisdictions it sells in. However, it’s important to mention that using Vertex is relatively expensive.
Since Vertex is focused on large enterprise clients with complex tax requirements, that’s who the product is best for. Vertex customers are typically large retailers and manufacturers, SaaS companies, and other companies that require its robust calculation engine and customizable features.
Vertex is beloved by its customers, with a rating of 4.3 stars (out of five) on its Capterra page, based on more than 75 reviews. Several customers tout the ease of use and the exceptional customer service that Vertex provides. However, others say that Vertex is a single point of failure that can cause big problems when it occasionally has an outage.
