Cbox Nexus: US tax rules for Laravel. Tracks state sales thresholds to warn when tax registration is required.

In simple English

This tool helps online shops keep track of US sales tax rules. Different states require you to collect tax once your sales pass a certain dollar amount. The tool adds up your sales for each state. It checks those numbers against state laws. It warns you when you need to register to collect tax.

What it is

Cbox Nexus is a PHP library for the Laravel framework that evaluates US economic nexus rules. It processes your sales data against official state thresholds to tell you where tax registration is required.

What it is good for

Solo builders running an online shop on Laravel who sell to customers across different US states and need to know when sales tax laws apply to them.
