Revenue Prediction - Orange Money

Abstract

Accurate revenue forecasting is critical for mobile financial services to support strategic planning, resource allocation, and risk management. Orange Money, as a major mobile money platform, generates large volumes of transactional data influenced by user behavior, seasonality, economic activity, and promotional campaigns. This work proposes a data-driven revenue prediction framework leveraging time-series modeling and machine learning techniques to forecast Orange Money revenues. By integrating historical transaction data with engineered temporal and behavioral features, the proposed approach aims to improve forecasting accuracy and provide actionable insights for decision-makers.

1. Introduction

1.1 Context and Motivation

Mobile money services have become a cornerstone of financial inclusion in many developing economies, particularly in West Africa. Orange Money plays a strategic role by enabling peer-to-peer transfers, bill payments, merchant transactions, and international remittances. However, revenue generated from these services is subject to strong temporal variations driven by seasonality, user adoption, socio-economic factors, and marketing campaigns. Traditional forecasting methods often fail to capture these complex dynamics, motivating the need for robust predictive models based on modern data analytics.

1.2 Objectives of the Study

This study begins by analyzing historical Orange Money transaction and revenue data to understand how usage behaviors translate into revenue. We examine key transaction types (e.g., transfers, cash-in/cash-out, bill payments, merchant payments) and track how volumes, values, and active-user activity evolve over time. Basic data quality checks, missing-value handling, and outlier detection are applied to ensure the dataset is reliable before deeper exploration.

Next, we model revenue dynamics to capture long-term trends, recurring seasonal effects, and growth patterns. This includes identifying weekly and monthly cycles, holiday and payday impacts, and structural shifts caused by promotions or market changes. Trend decomposition and feature engineering are used to separate the underlying growth signal from seasonal fluctuations, making it easier to interpret what is driving revenue changes over time.

Building on these insights, we develop predictive models for both short-term and medium-term forecasting. Short-term forecasts focus on near-future operational planning (e.g., days to weeks), while medium-term forecasts support strategic budgeting and resource allocation (e.g., months). We compare classical time-series approaches and machine-learning methods, integrating engineered temporal and behavioral features to better reflect real-world Orange Money revenue drivers.

To ensure the models are trustworthy, we evaluate forecasting performance using quantitative metrics and robust validation protocols. Forecast accuracy is assessed through measures such as MAE, RMSE, and MAPE, and tested across multiple time windows to confirm stability under different conditions (normal periods vs. peak seasons). This evaluation highlights which models generalize best and where forecasting errors are most likely to occur.

Finally, the framework is designed to produce interpretable insights that decision-makers can use. We translate model outputs into actionable explanations, such as identifying the strongest seasonal drivers, quantifying the effect of campaigns, and detecting early signals of revenue shifts. These insights help Orange Money stakeholders improve strategic planning, optimize promotional timing, manage operational capacity, and reduce financial uncertainty.

2. Related Work

2.1 Revenue Forecasting in Financial Services

Previous studies on revenue forecasting in banking and fintech emphasize time-series analysis and demand modeling. Classical approaches such as ARIMA and exponential smoothing are widely used, while recent work explores machine learning and hybrid models to capture non-linear trends.

2.2 Mobile Money Analytics

Research on mobile money systems focuses on transaction behavior, user adoption, fraud detection, and financial inclusion. Transaction volume, frequency, and customer segmentation are strong indicators of revenue evolution.

2.3 Time-Series and Machine Learning Approaches

Modern forecasting approaches increasingly rely on models such as Prophet, Gradient Boosting, and recurrent neural networks (LSTM) to handle seasonality, trend shifts, and external regressors, often outperforming traditional models on complex financial datasets.

3. Methodology

3.1 Data Collection and Preprocessing

The dataset consists of historical Orange Money revenue records aggregated at a fixed temporal granularity. Data cleaning includes missing value handling, outlier detection, and normalization.

3.2 Feature Engineering

• Temporal features (month, year, holidays)
• Lagged revenue values
• Rolling statistics (moving averages, growth rates)
• Optional external regressors (promotions, economic indicators)

3.3 Revenue Prediction Models

Several forecasting models are implemented, including ARIMA, additive time-series models such as Prophet, and machine learning-based regressors adapted for time-series forecasting.

3.4 Model Training and Validation

Models are trained on historical data using time-aware cross-validation strategies. Hyperparameter tuning is performed to optimize predictive performance while preventing data leakage.

4. Experimental Setup

4.1 Dataset Description

The dataset spans multiple years of Orange Money revenue data, capturing seasonal cycles and business phases. Exploratory analysis highlights trends, volatility, and growth patterns.

4.2 Training and Evaluation Protocols

Rolling-window and expanding-window evaluation strategies are used to simulate real-world forecasting conditions while preserving chronological order.

4.3 Performance Metrics

• Mean Absolute Error (MAE)
• Root Mean Squared Error (RMSE)
• Mean Absolute Percentage Error (MAPE)

5. Results and Discussion

The performance of the proposed revenue forecasting framework was evaluated using additive time-series models based on Prophet combined with systematic hyperparameter tuning. Model optimization focused on key Prophet parameters controlling trend flexibility and seasonality strength, enabling the model to adapt to complex temporal dynamics present in Orange Money revenue data.

Experimental results demonstrate that the tuned Prophet model achieves consistently high predictive accuracy across all evaluated months, with monthly forecasting errors remaining below 10%. This level of accuracy indicates that the model effectively captures long-term trends, seasonal patterns, and short-term fluctuations in revenue.

Hyperparameter tuning plays a critical role in improving forecasting performance. By adjusting parameters such as trend changepoint sensitivity and seasonal components, the optimized model reduces bias and variance compared to default Prophet configurations. The resulting forecasts exhibit stable behavior across different time periods, suggesting strong generalization to unseen data.

From an operational standpoint, maintaining prediction errors below the 10% threshold is generally considered acceptable for financial forecasting applications. The results therefore confirm that a Prophet-based forecasting framework, when combined with appropriate hyperparameter optimization, is well suited for short- and medium-term revenue prediction in mobile money services. These forecasts provide reliable quantitative support for financial planning, budgeting, and strategic decision-making.

Overall, the findings validate the effectiveness of combining additive time-series modeling with hyperparameter tuning for revenue forecasting in complex, real-world financial datasets.
