When Out-of-the-Box NetSuite Is Not Enough
NetSuite is a powerful platform, but every business has processes that standard configuration cannot handle — complex approval logic, automated calculations, custom external integrations, or industry-specific workflows that require code.
Cold Sun builds custom NetSuite solutions that extend the platform to fit your business precisely — written to upgrade-safe standards, fully documented, and built to survive NetSuite's semi-annual release cycle without breaking.
Many NetSuite developers build fast and move on — leaving behind undocumented code that breaks with upgrades. Cold Sun builds differently.
NetSuite That Fits Your Business Exactly
Upgrade-safe, documented, and built to last — Cold Sun development extends NetSuite without creating technical debt.
SuiteScript Automation
Custom scripts that automate complex business logic NetSuite cannot handle out of the box — validated transactions, automated workflows, and custom calculations.
Workflow Automation
SuiteFlow workflow automation for approval processes, notifications, and multi-step business processes — without custom code where workflows suffice.
Custom Reports & Dashboards
Saved searches, custom reports, and role-specific dashboards that give every user the operational visibility they need — built for your data model.
SuiteCommerce & Portals
Customer and vendor portals, SuiteCommerce implementations, and external-facing NetSuite experiences for B2B and B2C use cases.
API Integrations
RESTlet and web services integrations connecting NetSuite to Salesforce, e-commerce platforms, and every other system in your stack.
Cold Sun builds the full range of NetSuite customizations — from simple saved searches to complex multi-system integrations — all documented, tested, and upgrade-safe.
SuiteScript 2.x Development
Custom business logic — user events, scheduled scripts, Suitelets, RESTlets, and map/reduce scripts — built upgrade-safe and fully documented.
SuiteFlow Workflows
Visual workflow automation for approval processes, notifications, record creation, and complex conditional business logic without code.
Custom Record Types
Custom record types, fields, sublists, and forms that extend NetSuite to capture business data it does not handle natively.
Salesforce to NetSuite Integration
Bidirectional Salesforce-NetSuite integration connecting CRM and ERP — customers, opportunities, orders, invoices, and payments.
Third-Party API Integration
RESTlet-based integrations connecting NetSuite to any third-party system with an API — from shipping carriers to payment gateways.
Customer & Vendor Portals
SuiteCommerce or custom portal development giving customers and vendors real-time access to their NetSuite data.
