Custom software development in Sioux Falls.

Companies across Sioux Falls, SD come to Kadmoon when the software they can buy no longer fits how they work. The Sioux Falls area leans on Finance, Healthcare, and Food Processing, and those operations reward systems built for the exact workflow, not bent to fit one.

Custom software built for how Sioux Falls companies actually run

You do not need a vendor on your street to get software built right, but you do need one that understands the operations behind Sioux Falls's Finance and Healthcare sectors. Kadmoon works with US clients from our Austin base: senior engineers, US business hours, and delivery you can track from the first sprint.

Sioux Falls's financial employers deal with reconciliation, reporting, and compliance that generic tools handle poorly. We build platforms with the audit trails and controls those teams need.

What we build for Sioux Falls teams

From the core system to the model in production.

01

Enterprise Systems

ERPs, CRMs, and operational platforms designed around how your business actually runs—not generic software bent to fit. Every module is spec’d with measurable acceptance criteria.

02

SaaS Platforms

Multi-tenant products with recurring billing, white-label onboarding, analytics dashboards, and documented public APIs—architected to scale from 10 to 10,000 customers without a rewrite.

03

Mobile Apps

Native and cross-platform (React Native) apps for iOS and Android—product-grade UX, offline-first when needed, and direct integration with your backend.

04

Integrations & APIs

We connect your ecosystem: legacy ERPs, US Customs/ACE, payment gateways, marketplaces, and any third-party REST/SOAP API. Resilient middleware with retry, dead-letter, and full observability.

05

Data & AI

Ingestion pipelines, data warehouses, BI dashboards, ML models for forecasting and classification, and LLMs via RAG for semantic search, report generation, and intelligent automation—built into the system, not bolted on.

06

Legacy Modernization

Migration of COBOL, Delphi, VB6, and legacy .NET/PHP to a modern stack. Monolith-to-microservices refactoring, cloud migration, and elimination of critical technical debt.

Flagship practice

Trade & supply chain software, wherever you ship.

Customs and trade operations, US Customs/ACE integration, shipment tracking, landed cost, and end-to-end supply chain visibility in one system. It is our deepest domain, and it travels well to any Sioux Falls operation that moves goods.
