How to Develop Web-Based ERP Software in 2025

Let’s imagine you are trying to run a business using ten different tools, such as one for accounting, another for inventory, a different tool for payroll, and yet another for customer relationships.

Managing all these tools will take more time because when all of these tasks can be done using only one tool, then why waste time using different tools for each task? That is where web-based ERP software comes in as your business superhero.

It allows you to handle your business processes more easily. With the help of this connected system, you can access it from anywhere.

Now, instead of going from the spreadsheets to scattered apps, everything can happen in one place and that too in a more organised way, which also stays updated. But here is what is best about the web-based system: you aren’t stuck with a single computer.

You can open it on any device using the internet. This makes it easier to work from the office, home, or anywhere else. If you are developing a custom web-based ERP system, it can drastically improve how you run your business.

In this article, you’ll learn how to plan, build, and launch web-based ERP software. Whether you are new to ERP or thinking of building one for your business, this guide will help you understand the process clearly.

What is Web-Based ERP Software?

Web-based ERP software is a system that helps a business manage its daily work. These tasks can include accounting, sales, stock, and staff. Businesses can perform them using an internet connection.

It is not like your usual ERP software that runs only on a single computer or local server; instead, web-based ERP is hosted online and can be used on any device with a web browser.

This software allows business owners, managers, and staff to log in and use it from different places. This means whether you are in the office, at your home, or travelling, these web-based systems become helpful for you.

It keeps all the business data in one system, so everything stays updated and easy to manage. Some key parts of a web-based ERP include:

🔘Managing money and budgets

🔘Keeping track of stock and orders

🔘Handling staff records and salaries

🔘Following up with customers and sales

🔘Creating reports to help with decisions

Web-based ERP systems can be updated, maintained, and expanded easily. They also reduce the need for large hardware setups and allow teams to work more flexibly.

Steps to Develop Web-Based ERP Software

Now, let us learn more about how you can develop web-based ERP software. You can follow the steps mentioned below to start building the ERP software.

1. Planning Your ERP System

Planning is the most important step in ERP custom software development. It helps you understand what the software should do and how it is going to help your business.

🔘Set business goals: You first need to analyse the problems in your current processes. Maybe you want to reduce paperwork, save time, avoid duplicate data, or make reports easier. If you have clear goals, it will help guide the rest of the development.

🔘Understand user needs: You are developing an ERP software for your staff. That is why you need to talk to them, such as the staff from finance, HR, sales, etc. Learn about the daily tasks they perform and challenges they face. Their input will help you decide what features to include.

🔘List required modules: ERP software is made up of parts called “modules.” A different area of your business will be managed by each module. For example, an Accounting module helps manage money, while a Sales module tracks orders from your customers.

🔘Create feature lists for each module: Write down exactly what each module should do. This helps the software development partner build the right features from the beginning.

You should take time in the planning stage, as it will help avoid mistakes that can occur later.Database: Your business data is stored in the database. There are many options you can choose from the following:

2. Choosing the Right Tech Stack

The tech stack is the collection of programming languages, tools, and services used to build the ERP. If you choose a tech stack suitable for your business, the software will run smoothly and can grow with your business.

🔘Frontend (what users see): This is built using frontend technologies. These tools include React.js, Angular, or Vue.js. These tools help create user-friendly screens that work well on different devices, including mobiles and tablets.

🔘Backend (behind the scenes): This is where the logic and data processing happen. Some of the tools and programming languages used for backend development include Node.js (JavaScript), Laravel (PHP), and Django (Python). The backend manages requests, calculations, and data storage.

🔘Database: Your business data is stored in the database. There are many options you can choose from the following:

▪️ySQL, PostgreSQL (both are relational databases)

▪️MongoDB (a non-relational option)

You should choose a database based on your data type and how it will be used.

🔘Hosting: In this step, you also need to decide where to keep the software. Cloud platforms like AWS, Azure, or Google Cloud are popular because they are easy to manage and allow you to scale. On-premise hosting is also possible if your business needs to control the data completely.

The performance, cost, and security of your ERP system are impacted based on the tech stack you choose. So, it is important to select the stack very carefully.

3. Designing the ERP Architecture

ERP architecture is the entire structure of the ERP system. The design of your software should be one that can be built, tested, and maintained easily.

🔘Use a modular structure: You can start by breaking the software into smaller modules. Each module can work on its own, but also connect with others. This makes it easy for you to update or add features later.

🔘Set up user roles and permissions: It is not necessary for every employee to have access to all data. The system should allow you to give different permissions to different users based on their roles, like only HR can view salary details.

🔘Design APIs (Application Programming Interfaces): APIs allow your ERP to connect with other systems such as payment gateways, email platforms, or mobile apps. That is why if you build APIs from the beginning, the integration will become more easy in the future.

🔘Plan for data flow: Under this step, you also need to decide how data will move from one module to another. For example, when a sale is made, it should update both the inventory and accounting modules.

When your ERP architecture is designed clearly, it saves time during development and helps with changes you may want later.

4. Developing Core Modules

Now, it is time to start building the software. Developers will create each module. It will be done based on the features and structure you have planned.

🔘User management: This includes login pages, password settings, and user roles. This module allows admins to add or remove users and assign them to different roles.

🔘Dashboards and reports: A dashboard shows key information like sales numbers or stock levels. Reports help you make decisions that are better for your business by showing data in a clear way.

🔘Accounting module: This module handles billing, payments, tax calculations, expense tracking, and financial reports.

🔘Inventory module: It helps track the number of items in stock, alerts for low stock, and helps with inventory management.

🔘Sales and CRM module: It helps track customer details, sales history, follow-ups, and orders.

🔘HR and payroll module: This module stores employee records, attendance, leave requests, salary slips, and more.

Each module should be developed in stages. You can start with the most important features and then add extra ones.

5. Testing and Quality Assurance

Before the software is used by users, you need to test it properly to make sure everything works as you want it to.

🔘Functional testing: Check each feature to make sure it does what it’s supposed to do. For example, when you add a product to inventory, does it save correctly?

🔘Performance testing: You need to test the software with many users at the same time to see if it can handle heavy use and is also not affecting its performance and loading speed.

🔘Security testing: You also have to make sure data is protected and cannot be accessed by unauthorised users. This includes checking for common issues like weak passwords, unprotected data, or harmful code.

🔘Fixing bugs: Any issues found during ERP software testing should be fixed before moving forward. Testing helps reduce errors after launch.

With the help of this step, you can ensure the system is safe to use.

6. Deployment and Launch

Once testing is done and the software is ready, it is time to launch the ERP system.

🔘Set up a staging environment: This is a copy of the system used to do final checks before it goes live.

🔘Deploy to the live server: Next, you need to move the system to the server where users can access it.

🔘Connect third-party services: If your ERP needs to connect to email services, payment systems, or other tools, set these up during this stage.

🔘Monitor the system: You can use monitoring tools to check how the software is performing after launch. This helps you find any problems before they turn into a big issue later.

Your software launch should be done carefully, as it will help ensure users don’t come across any problems.

7. Post-Launch Support and Maintenance

Once your ERP is live, you will need to keep it running smoothly and make improvements regularly.

🔘Update software regularly: You should add new features, fix bugs, and keep the system safe by updating to the latest versions.

🔘Train users: You also need to provide help documents or video guides so staff know how to use the system. This reduces confusion and mistakes.

🔘Fix errors quickly: If users report issues, fix them as soon as possible to ensure they can keep using the system efficiently.

🔘Take backups: Regularly save a copy of the system data to avoid losing it due to errors or cyberattacks.

Good and regular maintenance keeps your ERP useful and working well for many years.

Cost of Developing Web-Based ERP Software

The cost of developing web-based ERP software ranges between £15,000 and over £100,000. The total software development cost can depend on the following factors:

🔘Number of modules

🔘Level of customisation

🔘Design complexity

🔘Development team location

🔘Required integrations.

A basic ERP with a few modules can cost around £15,000–£30,000, while a more advanced system with custom features, APIs, and detailed reports can cost you more than £100,000.

There can also be extra expenses, such as training, data migration, third-party licenses, and annual support, which usually account for 15–25% of the development cost.
