Quick comparison table

Both platforms offer web and API access. Avalara focuses on tax calculation and offers related tools for returns, exemption certificates, and reporting. Sovos covers more types of indirect tax and compliance work, including e-invoicing. Check current features, available modules, and pricing with each provider.

1. Avalara AvaTax

Best for: Businesses that need cloud-based sales and use tax calculation, with VAT and GST also in scope.

AvaTax calculates indirect taxes on transactions, helping businesses apply relevant rates across sales and purchasing workflows. Teams can access it through the web or API and assess how it fits with their existing systems.

A key strength is the way sales and use tax calculation sits alongside related compliance tools. Avalara also offers tools for returns, exemption certificates, and tax reporting, which may help businesses handle more than the calculation itself.

Check what comes with your specific setup before choosing. Returns, certificate management, and reporting may depend on the products or configuration you select. Confirm that they cover your jurisdictions and workflows.

2. Sovos Indirect Tax Suite

Best for: Businesses managing several types of indirect tax and related compliance requirements.

Sovos Indirect Tax Suite covers VAT, sales and use tax, and insurance premium tax. It also supports activities such as e-invoicing, filing, and reporting. Web and API access let businesses use the platform directly or connect it with other systems.

The suite’s main distinction is its range. It covers multiple tax types and compliance activities, rather than focusing mainly on transaction calculation. That may suit organizations with obligations across different tax regimes or a need for filing and electronic invoicing.

A broad feature set does not mean every module or jurisdiction will suit every buyer. Confirm which functions are available for your locations and requirements, and ask which modules you need for the compliance work you want to support.

How we picked these tools

This shortlist covers platforms explicitly positioned for indirect tax needs. We compared the types of tax each one covers and the compliance activities described, including calculation, filing, reporting, and related documentation.

We also looked at how each platform’s stated capabilities might fit different operational needs. Avalara pairs sales and use tax calculation with tools for returns, exemption certificates, and reporting. Sovos describes a broader suite covering VAT, sales and use tax, insurance premium tax, e-invoicing, filing, and reporting.

Both platforms offer web and API access, but that alone does not determine whether one is a fit. Integration requirements, jurisdictions, and the modules a business needs all matter. This is a concise comparison of stated product scope, not a ranking based on unverified pricing or hands-on testing. Check current product details with each provider before deciding.

Frequently asked questions

What does indirect tax software do?

Indirect tax software can help businesses calculate taxes on transactions and handle related compliance work, such as preparing returns, filing, reporting, or managing exemption certificates. The tasks available vary by platform and by the modules a business selects.

How does sales tax software differ from broader platforms?

Sales and use tax software focuses on those tax obligations. Broader platforms may also cover VAT, GST, insurance premium tax, or other indirect taxes. Businesses operating across multiple tax regimes may benefit from wider coverage, but should check that the specific jurisdictions and workflows they need are supported.

What should I check before choosing?

Start with the taxes and jurisdictions your business must manage. Then confirm integrations, required modules, and current pricing with the provider. Consider whether you need calculation alone or also returns, exemption certificates, e-invoicing, filing, or reporting. The right fit depends on your compliance work.
