ERPs manage financial data. Sales tax software manages compliance. Many businesses try to use their ERP for tax and run into problems as soon as they expand across states. The difference becomes clear when nexus, exposure, and multi-state obligations come into play.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What an ERP system does<\/h2>\n\n\n\n<p><strong>ERP systems like NetSuite and Odoo are built to:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Manage accounting<\/li>\n\n\n\n<li>Track transactions<\/li>\n\n\n\n<li>Generate financial
