# Chapter 2: ERP Quick Start Guide

## 2.1 ERP at a Glance

An Enterprise Resource Planning (ERP) system integrates multiple business departments into a single platform. All departments share the same database, allowing information to flow automatically throughout the organization.

The key principle of an ERP system is:

**Enter data once, use it everywhere.**

This eliminates duplicate work, improves data accuracy, and increases operational efficiency.

## 2.2 How ERP Works

Each department performs different tasks, but every transaction is connected.

A typical business process follows this sequence:

**Customer Inquiry → Quotation → Sales Order → Delivery Order → Outgoing Shipment → Sales Invoice → Payment → Financial Reports**

Information entered in one module is automatically available to the next module without requiring manual re-entry.

## 2.3 Business Workflow

The following example illustrates a standard sales process:

1. Create a quotation for the customer.
2. Convert the quotation into a Sales Order after customer confirmation.
3. Prepare and ship the products through the warehouse.
4. Update inventory automatically after shipment.
5. Generate a Sales Invoice.
6. Record customer payment.
7. Update accounting records and management reports automatically.

## 2.5 Common Documents

During daily operations, users will frequently encounter the following documents:

<table id="bkmrk-document-description"><thead><tr><th>Document</th><th>Description</th></tr></thead><tbody><tr><td>Quotation</td><td>Price proposal sent to a customer</td></tr><tr><td>Sales Order (SO)</td><td>Customer confirms the purchase</td></tr><tr><td>Delivery Order (DO)</td><td>Authorization to prepare and deliver goods</td></tr><tr><td>Sales Invoice</td><td>Official invoice requesting payment</td></tr><tr><td>Payment</td><td>Customer payment record</td></tr></tbody></table>
