# How do integrations, compliance, or internal systems affect website cost?

Integrations, compliance requirements, and internal system connections increase website cost through additional development hours, specialized expertise, testing cycles, and ongoing maintenance obligations. E-commerce sites requiring secure payment processing, CRM syncing, and inventory management typically cost 50-100% more than non-e-commerce sites of similar size and design quality.

Third-party API integrations with established platforms (Mailchimp, Salesforce, Stripe) are relatively straightforward. Legacy systems or proprietary platforms often require custom middleware, significantly expanding scope and cost. Compliance requirements such as GDPR, ADA/WCAG accessibility, HIPAA, or PCI DSS add auditing, documentation, and technical remediation layers; compliance alone can increase base cost by 30-50%. Basic payment integrations run $3,000 to $10,000, while complex e-commerce platforms with recurring billing, tax calculation, and multi-currency support can exceed $50,000\. Security hardening, including encryption, vulnerability scanning, and authentication systems, adds development time that must be validated before launch. The internal resource commitment extends beyond direct labor to opportunity costs: technical staff diverted to documentation and compliance evidence collection cannot work on other priorities simultaneously.
