The Challenge
The client’s ERP system did not support credit card payments, restricting transactions to cash-only options. This limitation resulted in an inflexible payment process, negatively impacting customer satisfaction and operational efficiency.
Integrating a modern payment solution into a legacy COBOL-based system posed a significant challenge, requiring precise coordination between platforms to ensure seamless functionality.
The system lacked automated tax calculation capabilities, forcing customers to rely on manual methods, which increased the likelihood of errors and delayed processes.
Our Solution
We addressed the challenges by implementing a comprehensive solution –
API Integration
We developed an API service to connect the NET1 Integrated Payment platform with the COBOL system. JSON files were used for seamless data exchange, ensuring accurate and secure communication between systems.
Payment Module Enhancement
We enhanced the ERP’s Order Entry (O/E) module by integrating credit card payment functionality. This allowed customers to complete transactions using credit cards alongside cash, improving user convenience and satisfaction.
Automated Tax Calculations
We integrated Avalara with the COBOL system to automate tax calculations based on country-specific regulations. This streamlined compliance processes and minimized the risk of errors.
System Compatibility and Security
The integration was executed without disrupting the existing ERP framework, maintaining system stability while introducing modern features. Enhanced security protocols ensured the safe handling of payment information.
Collaboration with Stakeholders
We worked closely with the client’s team to validate all changes, ensuring alignment with their goals and a smooth transition to the upgraded system.
Technologies Used
Our software architects and engineers are experts in using the latest technologies.

I wanted to take a moment to highlight and commemorate the efforts from our dedicated PIO team. To preface, the projects we work on here are complex, with rigid objectives, budgets, and timelines. Expectations are always high and are ever-changing. From the start of our relationship, the IO team was able to exceed expectations and make our business wishes a reality.
Over the past year I have worked with them, they have worked very hard to understand our highly customized system and troubleshoot things with little or no documentation while managing to keep the business up and running normally. Without the hard work and dedication they have shown, I know we would have had some issues causing downtime or lost production. I am looking forward to continuing working them in the next year as well.
I have been working with Programmers IO for more than 5 years now and I have been pleased with all projects and developers that I have worked with. We have had a few issues here and there but they have always fixed and made it right. They have been an excellent addition to our business.
