Introduction

A leading marketing agency specializing in retail rewards and loyalty programmes partners with prominent consumer brands to drive customer engagement through incentivized campaigns. These campaigns require customers to submit valid proofs of purchase (till slips) to qualify for instant rewards. The integrity, speed, and scalability of the validation process are essential to ensure a seamless experience for both the brand and the customer.

The Challenge

Before engaging with us, the agency relied on a fully manual process to review and validate each till slip submitted by customers. This involved visually checking the image for key campaign data such as purchase date, product names, and compliance with campaign rules. As campaign volumes increased, this process became inefficient and unsustainable:

• High operational costs due to increased manpower.
• Delays in reward distribution.
• Risk of human error and inconsistent validations.
• Difficulty identifying duplicates or fraudulent submissions.

The agency needed a scalable and accurate solution to automate the validation of high volumes of till slips while reducing human workload.

The Solution

We developed a custom Till Slip Validation Application designed specifically to automate the campaign validation process. The system:

• Accepts and processes customer-submitted till slips in real time.
• Uses intelligent image analysis and OCR (optical character recognition) to extract relevant data such as purchase date, store name, and products purchased.
• Checks for qualifying products based on each campaign’s rules.
• Flags invalid submissions and duplicate entries automatically.
• Provides a web-based portal for staff to manage exceptions and view reports.

The Process

1. Discovery & Requirements Gathering:

We collaborated with the agency to understand their current workflow, campaign mechanics, and data requirements.

Design & Architecture:

We designed a cloud-based solution capable of handling thousands of entries per day with high reliability and speed.

Development & Integration:

The application was built with robust OCR and validation logic, integrated with the agency’s existing reward platform.

User Interface & Admin Portal:

A user-friendly portal was created for internal staff to review edge cases, manage flagged submissions, and generate insights.

Testing & Optimization:

We ran parallel tests with real campaign data to fine-tune accuracy and performance before full deployment.

The Outcome

The till slip validation application transformed the agency’s operations:

• 82% reduction in manual processing workload.
• Only one staff member now needed to oversee exceptions via the portal.
• Significant reduction in processing time and human errors.
• Improved customer satisfaction due to faster reward delivery.
• Scalable infrastructure ready to support multiple concurrent campaigns with ease.
