The PRoblem

Selling across state lines adds up fast.

Multi-State Nexus
Marketplace Facilitator Rules
Variable Product Taxability
Ship-To Address Logic

Multi-state nexus, marketplace facilitator rules, and product taxability that varies by state turn ecommerce sales tax
into a moving target. AkuCalc handles the calculation; you stay focused on growing the business.

How the Integration Works

Calculation on every WooCommerce order.

AkuCalc connects to WooCommerce through an integration that Clarus built and maintains. Tax is calculated at checkout and returned to the order in real time.

What happens at checkout

1

WooCommerce sends the order

Ship-to address, line items, customer status, and product details flow to AkuCalc.

2

AkuCalc applies rules and rates

Current rates, marketplace facilitator rules, and your product taxability configuration are applied in real time.

3

Tax returns to checkout in real time

The correct sales tax is returned before checkout is completed, helping ensure accurate collection on every order.
