Custom software built for how San Antonio companies actually run

Kadmoon serves San Antonio companies the way a serious buyer expects: full-time engineers, a working demo every two weeks, and a system that ships with the repo, credentials, and runbook in your hands. You are never locked into us.

Whatever drives San Antonio's economy, the pattern repeats: real operations outgrow generic software. We build the system that fits your process instead.

What we build for San Antonio 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 San Antonio operation that moves goods.

Custom software in San Antonio: common questions

Do you build custom software for companies in San Antonio?

Yes. Kadmoon works with clients across the United States, including San Antonio, Texas, from our engineering base in Austin, TX. We handle discovery, architecture, build, QA, and go-live, all with a senior in-house team on US business hours.

What kinds of software do you build for San Antonio businesses?

Enterprise systems like ERPs and CRMs, multi-tenant SaaS products, mobile apps, integrations and APIs, data and AI features, and legacy modernization. Trade and supply chain is our flagship practice. Every system is custom and owned by you.

Do we own the code you build?

Completely. On delivery you receive the Git repository, CI/CD pipelines, infrastructure credentials, and an operational runbook. No lock-in and no permanent dependency on us, in San Antonio or anywhere else.

How fast can a San Antonio project start?

Tell us about the project and you get a technical proposal within one business day, covering scope, architecture, timeline, and investment. Discovery usually starts within a week or two of a signed scope.
