Best Sales Tax Software by Ecommerce Use Case
Best For Growing/Mid-Sized Ecommerce Businesses
Growing or mid-sized ecommerce businesses should look for software that can help their business automate sales tax processes as they expand into additional states and sales channels. TaxHero, Zamp, and Kintsugi are the top options for growing ecommerce businesses. These platforms provide different levels of automation and professional support at a more accessible cost than many enterprise-focused solutions.Best For Multi-State Ecommerce Businesses
Managing sales tax across multiple states requires robust compliance tracking as economic nexus thresholds are met. Businesses navigating multi-state obligations often evaluate platforms like Avalara, Zamp, and Taxwire to handle complex multi-jurisdiction calculations, state registrations, and recurring filing schedules.The right solution depends heavily on whether your organization needs lightweight dashboard software or an enterprise-grade tax engine to support expanded geographic footprints.Best For Fully Managed Sales Tax Compliance
Brands looking to completely offload their sales tax burdens frequently turn to fully managed compliance solutions. Specialized services, including TaxHero and Zamp, along with other top-tier managed platforms, aim to automate calculation processes while utilizing specialized support systems to handle filings and state notices.This operational approach allows businesses to outsource technical tax administration so internal teams can focus entirely on core growth strategies.Best For Ecommerce Marketplaces
Selling across diverse digital channels introduces unique compliance challenges due to differing marketplace facilitator laws. Merchants operating on multiple platforms typically look for software with native integrations for major networks like Shopify and Amazon.Solutions like Numeral, Kintsugi, and Avalara are designed to sync this multichannel transaction data cleanly, ensuring accurate reporting across all active sales platforms.Avalara vs TaxJar vs TaxHero
Choosing the right platform depends entirely on how your business sells products and how much help you want with your taxes.Avalara operates as a high-powered corporate engine built for massive scale, specializing in heavy-duty tools that also handle international taxes such as VAT, cross-border shipping rules, and custom database connections for large enterprises. TaxJar functions as a user-friendly software built for scaling independent online sellers who want full visibility over their tax liabilities. The platform specializes in organizing multichannel transaction data into clean reports and providing automated tools for store owners who prefer to manage their own filings. Meanwhile, TaxHero merges sales tax software features and compliance services by offering a completely done-for-you experience. Instead of giving you tools to manage yourself, TaxHero combines advanced automation tools with a dedicated team of real sales tax professionals, effectively acting as your personal, outsourced sales tax compliance department.How to Choose Sales Tax Software for Your Ecommerce Business
While there are several excellent sales tax software brands to choose from, the right product still depends on what your business needs. To choose the right sales tax automation software for your business, consider these 7 crucial factors:
- Coverage: Do you sell internationally? Or do you plan to keep your sales within the U.S. in the meantime? Some sales tax software supports global coverage; some do not. Look for the one that fits your business’s coverage.
- Future Plans: If your business is steadily growing, you can invest in more advanced software that covers your future sales tax requirements rather than sticking to simple software with limited features.
- Human Support: Good software will not function without real human support. Even if you are an independent business requiring minimal assistance, you will need a supportive team to handle your sales tax concerns, especially during the onboarding process, which generally requires technical knowledge.
- Accounting Expertise: Advanced AI sales tax software isn’t always guaranteed to work on its own, as technology can still have its hiccups. Therefore, you should check your brand’s background. Is it composed of accounting experts that you can directly turn to for assistance?
- Features Compatibility: Some software offers extensive features that may not always be beneficial for your business, such as providing GST or VAT compliance services, which may not be useful for businesses only selling within the U.S.
- Audit Support and Representation: Search for software that keeps everything in one place for you. In the event of an audit, you’ll have easy access to all the information you need to support yourself in an audit. Some brands will also represent your business directly, providing financial security and peace of mind.
- Automated Services vs. Done-For-You Service: In general, plenty of sales tax software tools can do automatic calculations and tracking. However, not all of them file and remit sales tax for you, including registering your business. If you’re searching for software that manages all your compliance requirements, look for software that offers a done-for-you service, like TaxHero or Zamp.
