For reference, third-party sources and reviewers indicate that Vertex’s pricing typically runs from $8,500 to $144,000 per year, with a median annual spend of around $33,000 for midsize and enterprise businesses.

My methodology
Here are the criteria I used to analyze the best sales tax software options:
Business requirements assessment: I began by pinpointing core business requirements, focusing on areas like multijurisdictional complexity, product and service taxability, anticipated growth, and whether manual processes or automation would be needed for filings and rate updates.
Features: I evaluated each platform for its process of handling rate updates, exemption certificate management, and automated return filing.
Integrations: Integration capabilities were assessed by looking at connections with ERPs, e-commerce platforms, and accounting tools.
Total cost: I analyzed the publicized pricing structure for each platform. The objective was to find solutions with transparent pricing and scalable plans. In the absence of this information, detail was provided on how to get more information.
Scalability: Each software was analyzed on its ability to support increasing transaction volumes, new geographic areas, additional users, and changing tax regulations.
Frequently asked questions (FAQs)
Are most sales tax platforms equipped to manage global sales tax regimes, such as VAT and GST?
Some platforms, like Avalara and Vertex, are set up to handle international sales.
How does the software verify the tax-exempt customer and certificate validity?
Sales tax software verifies tax-exempt customers by collecting exemption certificates during onboarding or checkout and validating them for format, jurisdiction, and expiration against current databases and government-issued numbers.
Do I have to file sales tax in every state?
If you have nexus (physical presence, remote employees, inventory, or exceeding economic thresholds), then yes, you have to collect and remit sales tax in the state. Without nexus, there’s no sales tax obligation.
