It moves based on how much of your system needs to change and how complex that system has become over time. Most projects fall between <strong data-start=\"218\" data-end=\"237\">$150K and $500K<\/strong>, but costs rise quickly when architecture, data, and integrations require deeper changes.<\/p>\n<p data-start=\"329\" data-end=\"547\">What matters is not just the upfront investment, but the direction of your spending. You either continue putting budget into maintaining a system that slows you down, or you invest in changing it so it supports growth.<\/p>\n<p data-start=\"549\" data-end=\"791\">In most cases, the decision becomes clear when you look at your system honestly. If it still works and only needs improvement, modernization keeps costs controlled. If it\u2019s limiting your business, rebuilding becomes the more practical choice.<\/p>\n<p data-start=\"549\" data-end=\"791\"><div class=\"cta-section red\">\r\n  <h4>Modernize, refactor, or rebuild.
