How to choose the right sales tax automation software

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: A 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 comprised 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 nation. Carefully decide your business’s needs before choosing which sales tax software you will invest in.
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.
