Imagine the worst sales manager’s nightmare: the company’s selling products online they don’t actually have in physical stock. So the staff needs to call the client and apologize for not being able to deliver the order. In situations like these, it’s much easier to lose customers than gain.

But if you have an ERP system with in-built inventory management module, your sales department can sleep well. Besides, ERP software is good for reconciling financials, creating sales forecasts, maintaining order volumes and increasing customer satisfaction. Yes, it can be done using 4-5 different platforms, but managing the data in one place is easier than in several places.

In our article, we’re covering ERP modules and their functions, main architecture types, ERP examples and explaining why custom ERP software is the best software. So if you want to find out how ERP system works – keep reading.

Types of ERP Modules and Their Roles

Complex systems are usually split into modules depending on the role they perform. ERP software is no different.

I’ve listed several basic ERP modules that companies request most often:

  1. Human Resources Management
  2. Planning
  3. Inventory Management
  4. Building Reports

Let’s review each group in more details.

Human Resources Module

Watching over employees’ performance may be hard even for small-sized companies, not to mention large enterprises. So if you're considering a tech solution for the company, it’s better to stop on custom systems rather than ready-made suites.

By using the system, HR department no longer needs to spend hours on manual performance evaluation or attendance monitoring. Besides, the human resources module also deals with maintaining employees’ contact information, salary details, promotions, and bonuses. So recruiters have all the necessary details at hand and it’s much easier for them to make informed decisions.

Planning

Enterprise planning software also performs data analysis and management. It helps with accessing data and making data-driven decisions besides production planning.

Planning module within an ERP system works great for improving the overall planning process. With the help of the system, managers can easily check information and schedules of various departments or distribute resources more efficiently.

Inventory Management

As mentioned, the inventory management module is a must-have when working with customers and suppliers. This way, the company’s staff will always be aware of what’s left in their warehouse and what is to be ordered.

Custom ERP system makes inventory management more flexible and keeps a stable inventory level. So the staff can simply forget about situations when something a client ordered is out of stock.

Building Reports

Any company, whether big or small, won’t run for long without an established reporting system. And that’s another advantage of ERP systems. Building detailed reports takes a lot of time, still, how else would managers know how successful their business is?

Daily, monthly, quarterly and yearly reports creation and printing is now a matter of a few minutes. And by using filters, the staff will remain sure that their reports contain only relevant details.

As you can see, custom ERP software helps to automize various processes. There’s no need to buy four different programs which are often complex and have a number of non-required features. In addition, don’t forget about UI/UX design. It’s hard to use poorly designed systems, and employees spend tons of time learning how to work with them.

Types of ERP Architecture

Currently ERP systems are divided into two categories: monolithic and postmodern. Each type has its own characteristics and different levels of flexibility. So it’s time to explain ERP architecture in detail.

Monolithic Systems

These systems have all the needed business management tools in one suite or application. They are developed with a single tech stack and by a single vendor. This way, users always know whom to contact if there’s any performance issue. So despite their implementation cost, traditional systems were able to find their customers, gaining a significant market share.

Our QA Engineers check every part of the product, so there will be no bugs or performance issues left.

But nowadays business owners have no interest in monolithic ERP systems that seem complex and are not flexible to business changes. In addition, small companies cannot afford to replace the whole ERP suite with each new process update as the system requires.

Postmodern Suites

Postmodern suites are more simple and user-friendly, compared to their predecessors. They are agile and do not contain lots of redundant tables and other complex solutions that were required for scalability in monolithic systems. And unlike traditional systems, postmodern ERPs are based on a few applications, not a single suite.

They do have core ERP modules, but they can be easily extended with external solutions. For example, basic modules would cover financial and order management, while additional solutions can help with HR or service quality management. Postmodern suites are moving with the times so they are driven by social media, mobile trends and cloud-based solutions.

Benefits of ERP Software and Why to Build It

In today’s business environments, it’s hard to move on without an ERP system. Among the main benefits of ERP implementation is automatization of manual tasks staff spends hours on and thus improves the overall business performance. So the staff can focus on more important initiatives. At the same time, you can collect real-time data for improving performance management and making data-driven decisions.

ERP software comes handy in lots of areas due to its in-built modules and flexibility. Here are a few advantages of ERP software:

1. Reduce operating cost

The company starts gaining profit as soon as the ERP system is implemented. Prepare to face the reduction of marketing expenses, inventory maintenance, production cost and so on.

Also, if you’re aimed at combining all business processes within a unified system, ERP is the right choice. By using the software, it’s easy to improve cross-department cooperation and increase staff’s efficiency.

2. Instant data access

With ERP systems, employees soon forget about hours spent on collecting necessary details. Instead, they can be accessed in just a few minutes. Works great for busy executives and department managers that need to access data quickly.

3. Defined planning process

It’s easy to understand the business objectives, targets and aims when you have a full list of business needs, outcomes, and assets all in one place.

Sure, ERP systems also have some disadvantages. The most common issue is the price. It’s almost impossible for small companies to develop an ERP suite for their own needs, only middle and large-sized corporations can afford it.
