What is ERP? 
ERP stands for Enterprise Resource Planning. It is a type of software that allows businesses manage and automate core business functions like Accounting, Human Resources, Inventory, Sales, Procurement, and more from a single, unified platform.
ERP systems connects every key area of your business so that information flows seamlessly from a single, unified platform, operations are synchronized and decision-making becomes data-driven. In essence, all departments access real-time data from one central source, ensuring alignment, accuracy and agility.
What Does an ERP System Do? 
At its core, an ERP system acts as your business’s digital backbone, giving different departments a centralized platform to:
- Share and access up-to-date information
- Automate manual and repetitive tasks
- Track and report on performance in real time
- Ensure consistency, compliance and auditability across the board
Modern ERP systems are modular, meaning you can start small by implementing what you need and expand as your business evolves.

Types of ERP Systems 
There are three main types of ERP deployment models:
1. On-Premise ERP
This is where your ERP Software is Installed and maintained on your company's own servers. This model allows for more control and customization, but requires internal IT support and infrastructure.

With the Cloud solution, your ERP is hosted online by a provider and is accessed via a web browser. This model is flexible, scalable, and cost-effective — ideal for SMEs.
