Delaware software company
Software built for the systems businesses actually run on
We design and build point-of-sale, USSD, SMS, and custom software — and put it directly onto the hardware your teams and customers already hold.
What we build
Four capabilities. One operating picture of your business.
POS Solutions
Complete point-of-sale systems for retail, hospitality, and field operations — from terminal interfaces to back-office reporting.
USSD Services
Menu-driven services that work on any phone, no app or data plan required — payments, alerts, and self-service at scale.
SMS Solutions
Reliable messaging for receipts, notifications, authentication, and campaigns, integrated directly into your workflows.
Custom Software
Purpose-built tools and integrations that connect your existing systems and remove the manual work in between.
Built directly into POS hardware
Your software. On the device.
Our SDK integration layers your brand, workflows, and business logic straight onto commercial POS terminals — so the device in your customer's hand runs exactly the experience you designed, payment to receipt.
- Native terminal applications with your branding and flow
- Payment, peripherals, and printer access through the SDK
- Remote deployment and updates across your fleet
