Each ecommerce sales tax software will have its own flavor, but in order to be considered for placement on this list it must cover the following functionality basics.

  • Manage sales tax compliance and tax calculations per sale, preferably with regional (state, country) specificities in mind

Is it easy to learn and master? Does the company offer good tech support, user support, tutorials, and training? Is it easy to launch and update sales details and compute taxes quickly?

Software Integrations:

Is it easy to connect with other tools? I look at all the ways in which these cloud-based tools connect to other providers to expand their functionality. Therefore, I include details on API information that will help you create custom integrations, pre-built options, and third-party software. Is it easy to connect with various Point of Sale software, ecommerce CRM software, or other ecommerce tools, like Shopify?

Value for Price:

I research these tools and find relevant information regarding their pricing. Small businesses are particularly price-sensitive, which makes this an important criterion. I lay out details on pricing per month on monthly plans, free trials, free versions, and more.

People Also Ask

I wanted to leave some space to discuss some of the most frequently asked questions related to ecommerce sales tax software.

How Does Ecommerce Sales Tax work?

A sales tax is a consumption tax that is charged as a percentage of the sale of a taxable product.

Typically, you need to charge sales tax in states or regions where your business has a physical presence or significant connection.

The general rule for ecommerce sellers when collecting sales tax is:

  1. If your business has a nexus in a state (legal jargon for significant connection), you are obligated to collect sales tax from online customers in that state.
  2. If your business does not have a significant connection or physical presence, you typically do not have to collect sales tax for online sales.

Having said that, a US Supreme Court ruling in June 2018 has made it easier for states to make it obligatory for all businesses, regardless of physical presence, to collect sales tax.

Also, through some business activities (especially in cases of ecommerce business), a nexus is often created outside your home state too. This might include a location, inventory, affiliates, personnel, a dropshipping relationship, or an economic nexus where the sale exceeds the transaction amount set by the state.

Do I Need To Charge Sales Tax When Shipping Out Of State?

In the US, most states collect sales tax based on destination. In other words, each sale is considered to occur at the place where the product is ultimately being used.

How Do I Charge Sales Tax For Online Sales?

With all these legal intricacies, collecting sales tax can feel a bit overwhelming. Do not fret. You can use sales tax software that will automatically calculate the right sales tax rates based on rules and rates of different jurisdictions.

Other Types of Ecommerce Software
