Comparing ERP systems
An ERP system is standard software that supports an organisation’s core processes as one connected whole. Systems rarely differ in what they can do, and almost always in what works without adaptation.

Where they really differ
What is an ERP system?
An ERP system brings the processes that live in separate tools and spreadsheets today into one connected whole. An order then changes stock, planning and the figures at once, without anyone retyping that step.
ERP system, ERP software and ERP package all name the same thing. System is the common term. ERP platform is sometimes used for a system others build extensions on, but that is a distinction in the technology, not a different product.
Nearly every mainstream system ticks nearly every box.
Which is why comparing feature lists gets you nowhere: on paper they all score about the same. The difference lies in what works as standard within your way of working, and what only works once it has been adapted.
Which types of ERP system exist?
Two questions split the market: does your sector impose its own way of working, and do you want to run the system yourself. Every other difference follows from those.
Fit and what to watch
| Type | Where it fits | What to watch |
|---|---|---|
| Broadly applicable | Organisations with conventional processes, where the sector does not dictate how work is done. | How much sector-specific work you will have to have built. That is the item that grows quietly. |
| Sector-specific | Organisations where the sector model drives the process, such as project-based production or maintenance. | The size of the partner market. Few suppliers means little room to move if it does not work out. |
| From the cloud | Those who want no in-house administration and are willing to move with the vendor’s update cycle. | That you do not set the pace of change. Testing becomes a recurring job rather than a project. |
| Self-hosted | Organisations with requirements around where data sits, or heavy links to systems of their own. | That maintenance, security and updates stay your responsibility. |
Which ERP systems do you meet in the Netherlands?
Different systems surface in different market segments. The table below shows where systems are typically deployed, so you know which direction to look in.
Systems per sector
| Sector | What you often meet | What to watch in this segment |
|---|---|---|
| Manufacturing | Isah, Ridder IQ, Infor, Microsoft Dynamics 365 Finance & Supply Chain Management, SAP S/4HANA. | Whether the system knows your production model: to stock, to order or to project. That distinction decides more than any module list. |
| Wholesale | Exact, Microsoft Dynamics 365 Business Central, SAP Business One, Odoo. | How the system handles stock across several locations, and pricing agreements that differ per customer. |
| Professional services | AFAS, Unit4, Microsoft Dynamics 365 Business Central, Odoo. | The link between hours, projects and invoicing. That is where most manual rework appears. |
| Maintenance | IFS, Infor, Microsoft Dynamics 365, Odoo. | Whether maintenance, planning and parts genuinely sit in one flow, or are two systems with a link between them. |
Not an exhaustive list and not a recommendation. Placement says where a system is typically deployed, not which system is better. We hold no partnership with vendors, so we have no stake in which name you choose.
Where do ERP systems genuinely differ?
Six differences you can see in a demonstration, and that decide your costs and your freedom after go-live.
That difference is not theory. In the 2026 ERP Report by Panorama Consulting, more than a quarter of organisations reported going over budget, and the most common cause was an unexpected need for additional technology.
What comes as standard, and what you have built
Nearly every system ticks nearly every box. The question is not whether something is possible, but whether it works as standard within your way of working.
Every adaptation you have built, you pay for again at every major update.
How the system handles exceptions
One vendor solves an unusual order inside the standard, another asks for a change. You only see that difference when you bring your own exceptions.
Test on your hardest order, not on your average one.
How much you can configure yourself
Some systems let your own people manage fields, screens and reports. With others you need the partner every time.
That difference drives your cost after go-live more than the licence does.
How integrations come about
Check whether links to your webshop, warehouse system or machines are available as standard, and who maintains them when either side changes.
An integration without an owner is an outage waiting for its moment.
The pace at which the vendor changes things
A cloud system updates on fixed dates whether you want it or not. Self-hosted, you pick the moment but carry the cost of falling behind.
Both need a standing test round. Only the timing differs.
How many partners can implement it
A large partner market gives you negotiating room and somewhere to go. With a niche system you depend on a handful of firms.
Choosing a system therefore quietly narrows your choice of partner.
What does this mean in your sector?
Which system fits depends heavily on your sector: the developments differ, the common systems differ, and the point at which a system starts to pinch moves with your growth.
ERP for manufacturing
What is happening in the sector, which systems run there and what each was built for, and where it pinches at every stage of growth.

Where your stock sits and which price belongs to which customer: two questions the system has to get right at once.

Your stock is your people’s calendar. Who is available, where the time went, and how much of it reaches the invoice.
Read about ERP in servicesHow do you get from a long list to three candidates?
Three candidates is workable. More rarely yields more insight, because the demonstrations become too shallow to compare.
- First record which processes earn the money, and which exceptions in them genuinely occur
- Establish whether your sector imposes its own way of working, since that decides broad against sector-specific
- Include a system you have never heard of, or the list only confirms what people already believed
- Narrow the list on demonstrable fit for your size and sector, not on how familiar the name is
Bear in mind that choosing a system narrows your choice of partner: with a niche system only a handful of firms can implement it. Read how to test a partner.
Frequently asked questions
- What is an ERP system?
An ERP system is standard software that supports an organisation’s core processes as one connected whole: purchasing, stock, production, sales and finance.
Its strength is that connection: an order changes stock, planning and the figures at once. That same connection explains why a wrong choice keeps costing you.
- What is the difference between an ERP system, ERP software and an ERP package?
Nothing. They are three words for the same standard software, and which one people use is mostly a matter of habit.
ERP platform is sometimes used for a system others build extensions on. That is a distinction in the technology, not a different product.
- Which ERP systems are used in the Netherlands?
The market runs from broad systems such as Microsoft Dynamics 365, Exact, AFAS and Odoo to sector-specific ones such as Isah, Ridder IQ and IFS, with SAP and Oracle at larger and international organisations.
Which of them fit depends on your processes, your size and your sector. A list says little without those three beside it.
- Is a sector-specific system better than a broad one?
Not by default. A sector system saves you custom work while your process follows the sector model, and costs you extra the moment it does not.
Weigh the partner market too: a smaller one leaves you less room to move if the working relationship falters.
- How many systems belong on a shortlist?
Three works in practice. More candidates rarely produce more insight, because the demonstrations get too shallow to compare.
What matters more than the number is that every candidate gets the same scenario. Otherwise you are comparing presentations, not systems.
