A customer places an order through the online store. Another comes from a salesperson. A third arrives by email. The sales team sees one status, the warehouse another, while accounting waits for the information needed to issue an invoice. This is where order processing becomes a problem.Not because there are too many orders, but because each one moves between people and systems. A separate order management system can bring these processes together. But an ERP can do the same in many cases. The question is which approach fits the way your company works.
Why does order management get harder as a company grows?
A small company can handle a surprising amount of manual work. Someone copies an order from an email into a spreadsheet, sends the details to the warehouse and later passes them to accounting. With growth, the same data may be entered several times.Stock information can become outdated, while employees spend time checking which version of an order is correct. The problem is not simply the number of orders. It is the number of handovers involved.
What can order management software do?
An order management software solution focuses on the order lifecycle. Depending on the system, it can collect orders from different sales channels, manage statuses, support fulfilment rules and connect information about stock and deliveries. This is useful for companies selling through several channels, where an online store, marketplaces and sales representatives generate orders with different fulfilment rules.A specialised OMS can provide one place to coordinate them. But it does not necessarily replace other systems. Inventory may still be managed in an ERP, customer information in a CRM and invoicing somewhere else. These systems then need to exchange data. Adding an OMS can therefore solve one problem while creating another: more integrations to maintain.
Could your ERP handle order management instead?
For some companies, the simpler answer is to manage orders within the ERP. In Odoo, for example, sales can be connected with inventory and invoicing processes, depending on the modules and configuration. The order can remain part of one workflow instead of being passed between applications.This can reduce manual handovers and give teams access to the same information. It also means that order management system and ERP are not always competing solutions. An ERP can cover much of the functionality companies look for in order management software. You can learn more about ERP systems and Odoo before comparing the two approaches.Inside the ERP, Sales, Inventory, CRM and Invoicing already share one system. A separate OMS has to sync with each of them instead.
When does a separate order management system make sense?
A separate OMS can be a good fit when order management itself is highly complex. For example, a company may sell through many channels, use different fulfilment rules or already have a mature ERP that works well for finance and operations but lacks the required order workflows.It can also make sense when replacing the existing systems would create more disruption than value. If the only reason for adding an OMS is that the company has more orders, another application may not be the best answer.
When is ERP-based order management better?
An ERP approach fits when the order someone enters in Sales is the same order Inventory reserves stock against and Invoicing bills, without anyone copying it into a second system to get there.
For most growing companies, one system to configure is simpler to keep running than three that all have to stay in sync.
Here's what changes once the order stays on one record, not three:
| Order management inside the ERP
| Separate OMS
|
| Where the order record lives
| The same record used by Sales, Inventory and Invoicing
| Its own database, separate from stock and invoices
|
| Other systems that need to stay in sync
| None, it's already one system
| Several: the ERP, the CRM, and invoicing or accounting
|
| What happens when stock changes
| Inventory updates on the same order, in the same transaction
| The OMS shows the new level once the warehouse system reports it back
|
| Generating an invoice
| The invoice is generated directly from the same sales order
| Order status is passed to accounting or the ERP to create it
|
| Fits best when
| Usually the cleaner choice - sales, inventory and invoicing already run in one place
| Order fulfilment itself is complex: many channels, different rules per channel
|
But before choosing either path, look at how one real order moves through your business today. Software should support that process, not define it.
What should you check before choosing?
Take one real order and follow it from start to finish.
- Where does it arrive?
- Who enters it?
- Where is stock checked?
- How does the warehouse receive the information?
- What triggers fulfilment?
- When does accounting get the data needed for invoicing?
Look for places where employees copy information, wait for another team or manually check whether data is still correct. You may find that the company does not need a separate order management system. The real issue may be how existing tools are connected or how the process was designed.
A separate OMS makes sense when order fulfilment is complex enough to justify a specialised system. For a growing company struggling with disconnected sales, inventory and invoicing tools, an ERP may offer a simpler way to bring the process together.
The right choice starts with the workflow, not the software category.If your company has outgrown spreadsheets and disconnected tools, Solvti's Odoo ERP services can help assess the current process and determine what should be handled within the ERP and where additional tools may be justified.
