Understanding ERP Before Understanding Odoo

Before we dive into how Odoo works we need to know what ERP software is about.

ERP is short for Enterprise Resource Planning. It is, like the brain of a company connecting all the parts of the business with shared information and standard ways of doing things.

If you do not have ERP your business might be using lots of systems that do not talk to each other.

  • CRM to manage customer information
  • Accounting software to manage money
  • Spreadsheets to keep track of inventory
  • Other apps to handle buying things
  • Email to manage approvals

As your business gets more complicated it gets harder to keep everything

Odoo ERP helps with this problem by giving you one place where all the information goes and it all works together.

For instance when the sales team puts in a sales order it can do lots of things automatically.

  • Set aside the inventory you need
  • Make delivery papers
  • Create bills
  • Update the accounting books
  • Tell you when you need to buy things

This makes things easier and helps your business run more smoothly.

How Does Odoo ERP Work?

Odoo ERP is a system that helps businesses by connecting all the parts of the company through one database.

When you put information into one part of the system other people in the company can see that information away.

Here is how it works:

Step 1 : Customer Inquiry

Someone who might want to buy something from the business gets in touch with them.

The sales team puts the persons information into the Odoo ERP system, which's like a big notebook that stores everything.

The system keeps track of:

  • Customer details
  • What the customer said
  • Possible sales
  • What the business needs to do

Step 2 : Sales Opportunity Management

The sales team tries to sell something to the customer.

  • Keep track of what the customer said
  • Schedule meetings
  • Send quotes to the customer
  • See how the sale is going

The people in charge can see how everything is going and what might happen in the future.

Step 3 : Quotation and Sales Order

If the customer likes the quote the business turns it into a sales order.

At this point Odoo ERP connects the sales team with the rest of the business.

Step 4 : Inventory Validation

The business checks if it has the products the customer wants.

If it does:

  • The products are set aside for the customer
  • The warehouse starts getting the products ready

If it does not:

  • The business might order products
  • The business might start making products

Step 5 : Delivery and Fulfillment

  • The warehouse team gets instructions on what to do.
  • They get the products ready. Send them to the customer.
  • The system updates how products the business has left.

Step 6 : Invoicing

The accounting team makes an invoice from the sales order.

This way the business does not have to enter the information twice.

Step 7 : Payment Collection

The business records the customers payment.

The financial reports update automatically.

The people, in charge can see how money the business has and how it is doing.

This is how Odoo ERP helps the whole business work together. Odoo ERP connects all the parts of the business like the sales team and the warehouse team into one system. This makes it easier for the business to work together and get things done.
