The Best 10 Free and Open Source Order Management Software (OMS)

The Best 10 Free and Open Source Order Management Software (OMS)

An unattended order equals an unattended customer. Order management is a significant operational activity for businesses. Any glitches in it can lower the company's ability to meet the bottom line. Right from the first inquiry at the point of sale (POS) to the shipment, delivery, and settlement of bills for products, order management involves multiple steps that have to be processed for efficient order fulfillment. Order management is required to speed up all phases of order fulfillment and provide a quick solution to customers for order related queries. In a nutshell, Order management is designed to take care of the whole process of order fulfillment.

Order management is the process of using structured methods, practical tools, and optimized processes to manage orders, improve order accuracy, work efficiency, and customer satisfaction. 

While the core idea of order management is to handle orders efficiently, still different types of industries require different types of order management system. Businesses use a well-defined order management system that is best suitable for their industry-specific needs. 

The order management system used by an e-commerce company such as Amazon that handles several hundred orders on a daily basis would be different from the one used by a stock market giant like Goldman Sachs that handles several hundred orders in nanoseconds. 

In both cases, manual handling of the orders is not possible. Companies require technology to handle orders at such a scale of business. They use order management software (OMS) that streamlines and automates the order processing tasks to create a flawless operational environment.

The satisfaction of a customer with a company’s service depends largely upon any of the company’s ability to handle its order management cycle.  An OMS helps companies in managing all phases of the order management cycle. For instance, the first step of the order management cycle is- demand forecasting, and planning the orders. It requires coordination between the marketing and the production department. OMS acts as a single point to feed information to both the departments. Other steps that follow include:

  • Generation of orders 
  • Estimation of the cost involved in that order
  • Generation of bills and invoices for that order
  • Prioritization of orders based on their inherent value to the company,
  • Scheduling of the order for its execution with the allotment of tasks to qualified workers and their teams
  • And finally, order fulfillment by delivering the order to customers

The order management cycle will also take care of the returns and after-sales services. The functionalities and tools of an OMS assist in all the above phases of the order management cycle.

What is Order Management Software?

Order management software (OMS) provides businesses all the tools and features needed for efficient management of their e-commerce orders. Order management software is used to enter and process various types of orders by businesses. Most of the OMS is an individual and standalone software suite dedicated totally for order management only. Some OMS are part or modules of the enterprise resource planning (ERP) system

OMS is designed to small various operational issues related to order processing and fulfillment. We have discussed a small case study to show how order management software can help in solving common issues of order fulfillment. 

#Case: A customer is trying to return a product that is defective with an order number in hand, but the customer care representative sees on his screen that the product falls into a no return/refund category. However, the customer mails him a screenshot of his purchase order that clearly shows that the product can be returned within 15 days of purchase. The customer care representative is not able to find the exact solution because of the lack of information on his/her screen about the complete order history. (The purchase was made using credit points awarded to the customer, and hence as a matter of policy it was non-refundable). As the company lacked proper order management software, this particular policy information was not visible to the customer nor to the representative.

How could have an OMS helped?

If the company had proper order management software, the applied custom fields would have prohibited the customer from buying a non-refundable product via credit points, or it would have removed the line stating that the product can be returned within 15 days of purchase.

Essential elements of Order management Software: 

Elements of OMS

  • Process Centralization:

By process centralization, organizations can have a single-window view of the complex order process. The centralized system displays order, inventory, and shipment related information on a single dashboard from where it can be controlled and coordinated.

  • Multi-channel Integration

The sales partners and other channels can be integrated with order management software to provide a single dashboard view of sales from multiple sales channels.

  • Automations:

Organizations can automate regular activities by OMS to reduce manual work. This system eases the order load, especially when the inventory turnover is high and businesses need to process hundreds of orders per day.

  • Shipping and Logistics

This element and its features take care of all the shipping and logistics related work of the business. 

  • Payment Processing

The software can be integrated with multiple payment channels to offer customers an easy influx of payment modes.  

  • Real-time analytics and reports

This element has features to provide various analytical reports regarding the orders and the business performance related to it.

Benefits of using Order Management Software:

  • Customer Satisfaction:

Order management software has the ability to take orders, process them and manage all related phases (order confirmation emails, notifications, cancel orders, repeat orders, refund, bill generation, order tracking)  associated with it. As a business, if you use OMS, then you can provide your customers with technology-driven visibility of their ordered merchandise. Your customers are able to view the status of their orders in real-time and find if the order is pending, dispatched, on the way, or delivered. Users can also have the option to see the refund process status. Most OMS have algorithms to decide whether the refund process should be initiated or not based on given inputs. All these things are automated by order management software, so customers need not wait for any manual updates by the customer care employees. The order management software can send emails with personalized messages for providing information about their orders. Personalized support for all order related queries and issues and proactive approach of your company will add a value proposition to your business that will always be cherished by your customers. You can simply imagine the extent of satisfaction customers will have when they are transacting with such an efficiently managed business. Their loyalty, trust, and confidence in your brand will increase manifold, and you will not only gain a competitive advantage but also your chances of getting more business increase tremendously.  

A perfect order should have

  • Decreased Workload

As most of your regular process is automated by the order management software, you can relax and focus on other essential aspects of your business. When you have a 24*7 assistant to take care of your orders, then you can sleep without worrying about order backlogs or missed orders. With OMS at your side, you don't need multiple teams to handle the various stages of order processing and order fulfillment. OMS, being versatile and able to multitask, will reduce your workload to very healthy levels.

  • Removes legacy bottlenecks

The traditional systems of order management lacked a proper coordination. In legacy systems, customer service, manufacturing, and logistics worked as separate entities with limited mutual coordination. This made it difficult for businesses to provide accurate information about the order status. Even the customer service agents found it difficult to answer the customer queries without dialing phones to the logistics or manufacturing departments. Now with order management software, businesses have complete visibility of their ordered products, and they can provide reliable and accurate information to the customers.  

  • Saves Costs:

With multiple stakeholders involved in businesses, it is difficult to integrate systems to manage everything from a central point. Order management software makes the integration of all major cross-functional partners involved in-order delivery, easy and affordable. Removal of redundant systems results in cost savings.

  • Complex Order Fulfilment

With many e-commerce companies disrupting the traditional market-place and increasing the customer expectations to an all-time new high, the need for single-touch technologies to process complex orders has increased exponentially. A complex order is generated when the order fulfillment requires the involvement of multiple delivery players and logistic companies. OMS can tackle this complexity with a seamless one point database integration and handling everything from a single touchpoint.

  • Saves Time

Earlier for any order related issue, companies required to have a series of communication at multiple points. They had to speak to manufacturing, logistics, distributors, and retailers, and also all of these had to be individually informed of any changes in the order process and time. It caused unnecessary delays and loss of revenue. Now with the order management software, the changes get updated to the centralized system in real-time, and other associated entities get informed automatically as they either have the controlled access to the information or are notified by auto-generated emails and SMSes.

The paradigm shift to B2C from B2B has compelled all businesses to change their core business strategies. When all businesses are striving towards enhanced customer engagement and complete customer satisfaction goals, they cannot afford to disappoint their customers at any cost. 

Times have changed, and there is a sea difference in the way orders were processed in the past and the way it is processed today. New techniques and concepts like Lean management, Kanban theory, and many more have brought an unprecedented improvement in the order management field. New fields and industries have started using OMS that earlier used paper and human interaction for receiving and executing orders. 

For example, if you remember how people used to trade on the stock market floor (floor trading) with order chits in the hands of the brokers shouting for buy and sell orders.  It was replaced with high-frequency order management software where orders for bulk trades can be put in the software, and the software finds the buyers and sellers automatically. It still required human involvement to decide the entry and exit prices, but now with the development of algorithmic trading in the financial securities market, Order Management software can trade on behalf of the companies or individuals. It can decide and execute all types of orders, such as a buy, sell, short sell, cover, or bracket order based on algorithms. It has been a game-changer in the stock market trading world.

It would be worthwhile to see how further developments in this field are going to change the way we conduct business. But one thing is for sure; one has to implement technology as soon as possible to keep businesses intact in the dynamic business world. Order management software is the first thing that you require to stay ahead of your competitors.
