API Integrations That Reduced Manual Workload by 80% for a Growing Retail Distribution Company
Client Type: Mid-size retail distribution company with nation-wide supply operations
Industry: Retail & Wholesale Distribution
The Challenge
The client managed operations across multiple systems including CRM, ERP, Inventory Management, Order Processing and Accounting, none of which communicated with each other. This created high dependency on manual tasks and human coordination.
Major Pain Points
- 70+ hours/week spent on manual data entry and reconciliation
- Frequent delays and errors due to duplicate data entry
- Slow order processing time affecting customer satisfaction
- No real-time visibility across sales, stock, and billing
- Staff spending more time on admin rather than growth
- Operational cost growing rapidly due to manual workflows
The company needed a unified automated system without replacing existing software, making API-based integration the most efficient and cost-effective solution.
