The best Avalara alternatives
#1Sovos
Best for: Enterprise global tax4.2/5 on

Starting priceSee website
Free planNo
Sovos is a global tax compliance platform covering sales tax, VAT, e-invoicing, and reporting for large enterprises operating across many jurisdictions. It suits multinational firms that need one system for US sales tax plus VAT in Europe, Latin America, and Asia, with regulatory updates handled by the vendor. The platform integrates with major ERPs and e-commerce systems.
The trade-offs are cost and complexity. Sovos is priced for enterprises, implementation takes time, and small firms will find it heavy. Even so, Sovos suits large companies that need global tax compliance depth beyond what Avalara or smaller rivals offer.
What we like- Global tax compliance depth
- Strong for large enterprises
- VAT and sales tax coverage
Watch out for- High cost
- Implementation takes time
- Complex for small firms

Vertex is a tax automation platform trusted by large companies for sales tax, use tax, VAT, and exemption certificate management, with deep tax content and integrations for SAP, Oracle, Microsoft, and other ERPs. Its calculation accuracy and audit trails suit firms with complex product taxability and multi-entity structures. Vertex also covers consumer use tax and returns.
The limits are price and setup. Vertex is priced for larger firms, implementation usually needs a partner, and the interface is dense for casual users. Even so, Vertex suits large companies that need proven tax automation with strong ERP ties and audit-ready records.
What we like- Deep US and global tax content
- Strong ERP integrations
- Trusted by large firms
Watch out for- High cost
- Implementation needs partners
- Interface is dense
#3TaxJar
Best for: E-commerce sales tax4.7/5 on

Visit taxjar.com
Starting priceSee website
Free planNo
TaxJar, now part of Stripe, is a popular sales tax tool for e-commerce sellers, calculating tax at checkout and filing returns automatically through AutoFile in many states. It integrates with Shopify, Amazon, WooCommerce, and other channels, and it tracks economic nexus so sellers know where they must collect tax. The interface is simpler than enterprise platforms.
The trade-offs are ownership and scope. TaxJar is now tied to Stripe, pricing grows with transaction volume, and global VAT depth trails Sovos and Vertex. Even so, TaxJar suits e-commerce sellers who want simple calculation plus automatic filing without enterprise complexity.
What we like- Simple e-commerce setup
- AutoFile for state filings
- Integrates with Shopify and Amazon
Watch out for- Now part of Stripe
- Pricing grows with transactions
- Less global depth than Sovos
#4Anrok
Best for: SaaS sales tax4.5/5 on

Visit anrok.com
Starting priceSee website
Free planNo
Anrok is a sales tax platform built for SaaS and digital product companies, handling nexus monitoring, registration, calculation, and filings across all US states. It suits software firms whose taxability varies by state and product type, since SaaS tax rules differ sharply from physical goods rules. Anrok integrates with Stripe, Chargebee, and other billing systems.
The limits are focus and price. Anrok is SaaS-focused, so physical goods depth is thinner, pricing is quote-based, and the vendor is newer than Sovos or Vertex. Even so, Anrok suits SaaS and digital companies that want tax automation built for their business model.
What we like- Built for SaaS and digital goods
- Nexus monitoring
- Filings in all US states
Watch out for- SaaS focus means less physical goods depth
- Pricing is quote-based
- Newer vendor
#5Numeral

Free planNo
Numeral is a sales tax compliance platform for SaaS and e-commerce firms, offering nexus tracking, registrations, filings, and AI-assisted product categorization. It suits growing firms that want managed filings without hiring a tax team, since Numeral handles returns in many states. The platform integrates with Stripe, Shopify, and accounting tools.
The trade-offs are maturity and price. Numeral is newer than TaxJar or Vertex, pricing is quote-based, and the ecosystem is smaller. Even so, Numeral suits SaaS and e-commerce firms that want managed sales tax filings with modern tooling.
What we like- SaaS and e-commerce focus
- Managed filings
- AI-assisted categorization
Watch out for- Newer vendor
- Pricing is quote-based
- Smaller ecosystem than TaxJar
#6Stripe Tax
Best for: Stripe checkout tax4.5/5 on

Visit stripe.com
Starting priceSee website
Free planNo
Stripe Tax adds sales tax and VAT calculation directly inside Stripe checkout, using the customer's location to apply the right rate and to generate tax reports. It suits businesses already processing payments through Stripe that want tax calculation without a separate vendor, since setup is minimal and rates update automatically. Stripe Tax also supports invoicing and subscriptions.
The limits are scope and filings. Stripe Tax only covers Stripe payments, filing support varies by jurisdiction, and depth trails full platforms such as Sovos or Anrok. Even so, Stripe Tax suits Stripe-based businesses that want simple, integrated tax calculation at checkout.
What we like- Built into Stripe checkout
- Automatic calculation
- No separate integration for Stripe users
Watch out for- Only for Stripe payments
- Filing support varies
- Less depth than full tax platforms
#7TaxCloud
Best for: Free filing for small sellers4.5/5 on

Visit taxcloud.com
Starting priceFree
Free planYes
TaxCloud is a sales tax service that offers free calculation and filing for qualifying small sellers in Streamlined Sales Tax member states, funded by the states themselves. It suits small sellers who need basic compliance without a monthly platform fee, and it integrates with common e-commerce platforms. The free tier covers a meaningful set of states for many small firms.
The trade-offs are coverage and depth. Free filings cover SST states only, the feature set is smaller than TaxJar or Anrok, and support is basic. Even so, TaxCloud suits small sellers who want free, legitimate sales tax filing in covered states without paying for a full platform.
What we like- Free for qualifying small sellers
- SST member states coverage
- Simple setup
Watch out for- Limited to SST states for free filings
- Smaller feature set
- Support is basic

Kintsugi is an AI-driven sales tax automation platform that tracks nexus, manages registrations, and files returns for e-commerce and SaaS firms, with a modern interface and automated workflows. It suits growing firms that want automation with less manual work, since its AI tools categorize products and flag nexus risks. The platform integrates with Shopify, Stripe, and other systems.
The limits are maturity and price. Kintsugi is newer than TaxJar or Sovos, pricing is quote-based, and its track record is shorter. Even so, Kintsugi suits growing e-commerce and SaaS firms that want AI-led tax automation with a modern experience.
What we like- AI-driven nexus and filings
- Good for e-commerce and SaaS
- Modern interface
Watch out for- Newer vendor
- Pricing is quote-based
- Smaller track record than rivals
How we chose
We compared Avalara alternatives on tax calculation accuracy, nexus tracking, filing coverage, ERP and e-commerce integrations, and pricing, favoring vendors with proven filing records. We excluded tools that only calculate tax without filing support, except Stripe Tax, which pairs calculation with Stripe reporting. We also weighed how each vendor handles rate changes, since states and localities update rates often and stale rates cause under-collection that the seller must cover. Tax rules vary by state, country, and product type, so this article is general information only, not tax advice, and prices are quote-based or tiered, so we wrote See website where a vendor does not publish a clear starting price.
Buying guide
Start by listing where you sell and what you sell, since nexus and taxability depend on states, countries, and product type. SaaS firms face different rules than physical goods sellers, and a tool built for one may fit the other poorly. Marketplace sales add another layer, since marketplaces such as Amazon and Etsy collect tax on your behalf in many states, and your tool must avoid double-counting those sales. Next, check filing coverage: a tool that calculates tax but does not file in your states leaves the hardest work manual, so confirm filing states before buying.
Then compare total cost by transaction volume, since pricing grows with sales and can exceed expectations for fast-growing firms. Ask about audit support too, since a vendor that stands behind its filings and helps during audits is worth more than a cheaper tool that leaves you alone. Check exemption certificate handling as well, since B2B sellers with exempt customers need certificate collection and validation, and poor handling creates audit risk. Finally, talk to a tax professional about your specific situation, since no software replaces advice for complex nexus, exemption, or international questions, and a short consultation can prevent costly filing mistakes.
Frequently asked questions
What is an Avalara alternative?
It is a sales tax platform other than Avalara that calculates, collects, files, and remits sales tax, such as Sovos, Vertex, TaxJar, Anrok, or Stripe Tax, each with different strengths by company size and sales model.
Do I need sales tax software?
If you sell in many states or countries, yes, since nexus rules, rates, and filing deadlines vary widely and manual tracking breaks down fast. Small sellers in one state may manage with simpler tools or TaxCloud, but even they should track thresholds in case sales grow into new states.
What is economic nexus?
It is a sales threshold, usually based on sales amount or transaction count in a state, that requires out-of-state sellers to collect and remit that state's sales tax even without a physical presence there at all.
Is Stripe Tax enough for my business?
It suits Stripe-based businesses that need calculation at checkout, but filing support varies by jurisdiction, so firms with complex filings may need a full platform such as TaxJar, Anrok, or Sovos alongside it for returns.
Should I ask a tax professional before choosing?
Yes. Tax rules vary by state, country, and product type, and no software replaces professional advice for complex nexus, exemption certificates, or international VAT questions.
