The integration of blockchain technology and artificial intelligence (AI) with customer relationship management (CRM) and Enterprise Resource Planning (ERP) is examined in detail in this study. Integrating AI and blockchain technology with ERP and CRM is a game-changing strategy for enhancing ecosystem trust, data security, and customer experiences. Large-scale consumer data is analyzed by AI algorithms to forecast behavior, streamline workflows, and personalize interactions—all of which increase productivity. Blockchain ensures data integrity and secure, transparent transactions. CRM/ERP systems are improved by artificial neural networks (ANNs), a branch of AI, which raise revenue and improve customer satisfaction. Blockchain gives businesses control over critical data by offering an unbreakable ledger. Smart contracts streamline procedures and reduce conflicts by automating and enforcing CRM processes. The transparency of blockchain technology fosters reciprocal trust between businesses and customers. Two case studies are dealt with here using Kaggle datasets: (i) Creation of a CRM/ERP for online retail through data analysis and (ii) Linear regression analysis of an ANN-based sales prediction model. The performance is assessed through analysis of the prediction of the most valued customers based on the profit of customer segmentation for the CRM/ERP and through R-squared value (0.816), accuracy (0.82), precision (0.81), F1-score (0.82), recall (0.81), and Root Mean Square Error (0.792) for the ANN-based model. Finally, some studies on blockchain integration have been presented.
