Avalara Review: Is It Worth the Cost
Core Products
AvaTax is Avalara's real-time tax calculation engine. It integrates with your ecommerce platform and calculates the correct combined tax rate for every transaction at checkout, using the customer's shipping address to determine jurisdiction and your product's tax code to determine taxability. AvaTax covers US sales tax, Canadian GST/HST/PST, EU VAT, and other international tax types, making it the only ecommerce tax solution that handles both domestic and international tax compliance in a single platform.
Avalara Returns is the automated filing service. It takes your transaction data from AvaTax (or manually imported data), generates state-level returns with the correct jurisdictional breakdowns, and files them electronically with each state by the deadline. Returns also handles payment remittance and maintains confirmation records. The service covers all 45 US sales tax states plus DC, with no limitation to SST member states like some competitors.
Avalara CertCapture manages exemption certificates for B2B sellers. When a customer claims tax-exempt status, CertCapture stores their exemption certificate, validates it against state requirements, tracks expiration dates, and automatically requests renewals. During an audit, you can pull all certificates for a given customer or state in seconds. For sellers with significant B2B revenue, CertCapture eliminates the filing cabinet of paper certificates and the risk of missing certificates during an audit.
Pricing
Avalara does not publicly list prices for most of its products, which is its most common criticism from small business users. Pricing is determined through a sales conversation and depends on your transaction volume, the number of states you file in, which products you need (AvaTax, Returns, CertCapture), and your contract length. Based on publicly available information and user reports, expect the following ranges.
AvaTax for small ecommerce businesses starts at approximately $50 to $100 per month for basic real-time calculation with a limited number of transactions. Mid-tier plans for sellers processing 1,000 to 10,000 transactions per month typically run $150 to $300 per month. Enterprise plans with high transaction volumes, custom integrations, and dedicated support start at $500+ per month.
Avalara Returns pricing is approximately $20 to $30 per state per month for automated filing, comparable to TaxJar's AutoFile pricing. CertCapture pricing varies based on the number of certificates managed, typically starting at $50 to $100 per month. Annual contracts often include discounts of 10% to 20% compared to month-to-month pricing.
The total cost for a mid-sized ecommerce seller using AvaTax plus Returns in 10 states is typically $350 to $600 per month. This is higher than TaxJar's comparable setup ($349 for Professional plus 10-state AutoFile), but the difference is smaller than most people assume, and Avalara's advantages in product taxability accuracy and additional features (CertCapture, international tax) can justify the premium.
Product Taxability Accuracy
This is where Avalara genuinely separates itself from every competitor. Avalara maintains a tax content research team that continuously tracks legislative changes, rulings, and interpretations across all US tax jurisdictions and internationally. The product taxability database classifies millions of products across hundreds of tax categories, with state-by-state taxability rules for each category.
The practical impact shows up in edge cases that other platforms mishandle. A "protein bar" might be classified as food (exempt in many states), a dietary supplement (taxable in most states), or candy (taxable with different rules), depending on its ingredients, nutritional label, and how each state defines these categories. Avalara's classification system has specific codes for each variation, while simpler systems like TaxJar may apply a single "food" or "supplement" code that does not capture these distinctions.
For sellers of standard tangible goods (electronics, home goods, tools, accessories), the accuracy difference between Avalara and TaxJar is negligible. Both get the rate right and both correctly identify these products as taxable everywhere. The difference matters when you sell clothing (exempt in some states, taxable in others, with varying definitions of what counts as clothing), food and beverages (complex exemption rules that vary by state, product type, and preparation), digital products (rapidly changing taxability rules across states), SaaS and software (some states tax it as tangible personal property, others as a service, others exempt it entirely), or medical devices and supplies (varying exemptions based on prescription status and product type).
Integrations
Avalara offers over 1,200 pre-built integrations, the largest library of any tax automation platform. For ecommerce, the key integrations include Shopify (native integration through the Shopify app store), WooCommerce (through the AvaTax plugin), BigCommerce (native integration, BigCommerce uses Avalara as its default tax calculation provider), Magento/Adobe Commerce, Amazon Seller Central, eBay, Etsy, Walmart Marketplace, and QuickBooks Online and Desktop.
Avalara also integrates with ERP systems (NetSuite, Sage, SAP, Microsoft Dynamics), accounting software (Xero, FreshBooks), and custom platforms through its REST API. The API is well-documented and supports real-time rate lookups, transaction recording, address validation, and nexus analysis. For businesses with custom-built ecommerce systems or complex multi-platform architectures, Avalara's API and integration breadth provide connectivity that smaller platforms cannot match.
Strengths
Unmatched product taxability accuracy. If you sell products with complex or varying taxability across states, Avalara's classification depth prevents costly miscalculations that simpler systems miss.
Exemption certificate management. CertCapture is a genuine differentiator for B2B sellers. No competitor offers comparable certificate storage, validation, and audit-ready reporting integrated directly with the tax calculation engine.
International tax support. AvaTax handles EU VAT, UK VAT, Canadian GST/HST/PST, Australian GST, and other international tax types, making it the only solution a growing ecommerce business needs for both domestic and international compliance.
Integration breadth. With 1,200+ pre-built connectors, Avalara works with virtually any ecommerce, ERP, or accounting platform, reducing the risk that you will outgrow the platform as your technology stack evolves.
Limitations
Opaque pricing. The requirement to speak with sales for pricing makes it difficult to evaluate cost before committing. Many small business users report spending 30 to 60 minutes on a sales call before getting a quote, which is a friction point that TaxJar avoids with published pricing.
Complex setup. Avalara's depth means more configuration options, which translates to a longer setup process. While TaxJar can be configured in 15 to 30 minutes, Avalara setup, especially with product taxability mapping and multi-platform integration, can take several hours to several days.
Overkill for simple compliance. A seller of standard tangible goods collecting in 5 states does not need Avalara's product taxability depth, CertCapture, or international tax support. Paying for these capabilities when you do not use them means paying a premium for features that do not benefit your specific situation.
Contract terms. Avalara typically requires annual contracts, which reduces flexibility compared to TaxJar's month-to-month availability. Early termination fees may apply.
Who Should Use Avalara
Avalara is the right choice if you sell products with complex state-by-state taxability rules (food, clothing, digital goods, supplements, SaaS), you have significant B2B revenue and need exemption certificate management, you sell internationally and need VAT/GST compliance alongside US sales tax, you use an ERP system and need deep integration beyond basic ecommerce platforms, or you are processing high transaction volumes (10,000+ per month) where enterprise-grade infrastructure matters.
If your needs are simpler, standard tangible products, 5 to 15 states, US-only sales, no B2B exemptions, TaxJar provides comparable core functionality at a lower cost with an easier setup process. The sales tax software comparison covers the full range of options at every price point.
