Charleston & Summerville, South Carolina

Custom Software
Development in Charleston, SC

ERP systems, CRM platforms, inventory tools, and web applications — built from scratch to fit exactly how your Charleston business operates. No more bending your workflow to fit software that was built for someone else.

Software That Fits
Your Business — Not the Other Way Around

Off-the-shelf software like QuickBooks or Salesforce was built for the average business. If your operation is anything but average — and most are — you're constantly working around the software's limitations instead of having it work for you.

We build custom software for Charleston and Summerville businesses that mirrors exactly how you operate. Your terminology, your workflows, your reports. Built on a modern stack (Azure, .NET, Blazor, Supabase) that scales with you.

What We Build

ERP Systems

End-to-end enterprise resource planning — inventory, production, purchasing, invoicing. Built for your industry, not a generic template. (See: Knox Wire Harnesses ERP)

CRM Platforms

Customer relationship tools that track leads, jobs, and communications the way your team naturally works. (See: SaltCRM — live in the App Store)

Inventory Management

Replace spreadsheets with a real system — barcode scanning, reorder alerts, supplier tracking, and reporting built around your actual stock.

Web Applications

Complex, cloud-hosted web apps with real-time data, user authentication, and custom dashboards. Built to handle whatever your business demands.

AI-Integrated Tools

Automate repetitive tasks, generate reports, and surface insights using AI — built into software your team already uses every day.

API Development & Integration

Connect your existing tools — POS systems, accounting software, shipping platforms — through custom APIs that make your stack work together.

Frequently Asked Questions

Do you build custom software in Charleston SC? +

Yes. We build custom ERP systems, CRM platforms, inventory tools, and web applications for businesses in Charleston, Summerville, and across the greater Lowcountry.

What's the difference between custom software and off-the-shelf? +

Off-the-shelf software is built for the average business. Custom software is built for your specific workflows, your data, and your team — so it fits perfectly instead of almost.

Have you built real ERP or CRM software? +

Yes. We built Knox Wire Harnesses' production ERP system, currently in active daily use. We also built SaltCRM, a live CRM for field service contractors in the App Store and Google Play.

How much does custom software development cost? +

Simple tools start around $5,000–$15,000. Full ERP or CRM systems run higher. We'll scope your project honestly and give you a detailed estimate — no cost, no obligation.
