Top 10 Sovos Alternatives for Easier, More Transparent Sales Tax Compliance

Sovos is a global tax compliance solution. However, many users seek alternatives as they find the platform complex and less flexible.

If you are currently using Sovos and are unhappy with its service, you are not alone in such a predicament. Although Sovos is popular for its global coverage and regulatory depth, some users find it too expensive and overly tailored to large enterprises. Others are not satisfied with the customer and onboarding process.

If you are looking for a Sovos alternative for your SaaS or ecommerce company, we can help you find the one that best fits your business needs.

Why Do Users Look for a Sovos Alternative?

Sovos is a leading sales tax compliance solution, yet mid-sized and growing businesses often find it expensive, complex, and slow to respond to support requests. Here are key reasons users consider alternatives.

Overly Complex and Difficult to Use Interface

Users often find Sovos complicated, especially when configuring custom tax rules, which creates a steep learning curve and impedes onboarding. Many need extra support, leading to frustration.

Lack of Transparency in Pricing

Sovos uses quote-based pricing that varies by business size and transaction volume. However, some users find the pricing confusing. Others reported surprise charges for features they believed were already included in their plan. The lack of transparency in pricing leaves users unhappy, especially because it affects their compliance budget.

Slow or Unresponsive Customer Support

Users often wait days for Sovos customer support to resolve issues, which is unacceptable for time-sensitive sales tax compliance. Many seek alternatives with guaranteed response times.

Integrations Can Be Unreliable or Limited

Sovos integrates with several billing, ERP, and ecommerce platforms. However, it’s not as seamless as they expected. Its inconsistent performance led to delayed syncing, module-specific errors, and mismatched data. These technical problems only increase IT overhead and reliance on support.

Audit Trail and Reporting Features Fall Short

Sovos creates compliance reports, but some users struggle to access full audit trails or revision histories in one place. Incomplete reports force users to do manual, error-prone tracking that wastes time.

Portal/Module Fragmentation

Sovos includes multiple modules, but users say they don’t always work well together. Changes in one module can cause problems in others, increasing operational burden.

Billing & Service Cancellation Issues

Users complain that Sovos billed them after they canceled service. Getting refunds or stopping auto-renewals is difficult, eroding user trust.

Key Criteria for Choosing a Sovos Alternative For Tax Compliance

You need to identify the key elements in sales tax compliance and your business to find the best fit for you. Among the factors to consider are tax jurisdiction, automation capacity, and other relevant aspects.

Tax Jurisdiction Coverage

Every business aims to scale globally and if you are close to expanding internationally, choose one that supports it. Make sure that the sales tax compliance solution supports US sales tax, EU VAT, Canadian GST, and other global tax rules. If you’re not yet selling internationally, it’s still important to consider future-proofing your solution with support for VAT, GST, and cross-border compliance. So, the Sovos alternative should let you scale without worrying about your global tax obligations.

Filing and Remittance Automation

A great Sovos alternative not only calculates tax but also manages filing and remittance automatically. Manual filing can take too much time; worse, it may result in delays and errors. Late and inaccurate filing and remittance could mean penalties and interest. It can also increase your audit risk. So, find a sales tax automation provider that files your returns on time. It should also include visibility into upcoming deadlines and historical filings.

Real-Time Tax Calculation Accuracy

The best Sovos alternative should deliver accurate tax calculations. This should not be a hit-or-miss because accurate calculation is key to tax compliance. So, look for a platform that supports real-time tax rates and automatically adjusts calculations based on the recent rates. Inaccurate calculations can lead to under- or over-collection of taxes, which can strain your relationship with your customers and subject you to legal exposure.

Integration with Your Tech Stack

Your tax automation provider should easily connect with your billing, ERP, and ecommerce systems for reliable syncing and reporting. This means you should be able to connect all the data with minimal disruption.

Transparent Pricing and Scalability

Another major pain point among Sovos users is its unpredictable pricing. Find a Sovos alternative that offers transparent and flexible pricing. Consider how pricing scales as your business grows. What starts affordable can become expensive if transaction volume, tax filings, or international operations increase. Choose a provider that won’t penalize your growth.
