Because sales are digital and scale quickly across states, thresholds are often crossed without notice. Most SaaS companies underestimate when they owe sales tax. Nexus is not based on where your company is located. It is based on where your customers are.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What SaaS nexus means<\/h2>\n\n\n\n<p><strong>SaaS nexus determines:<\/strong><\/p>\n\n\n\n<ul
