ERP for wholesale
Wholesale turns on two things the system has to get right at the same time: where your stock sits, and which price belongs to which customer. Every other problem starts where those two drift apart.

What pinches at each stage
What is happening in wholesale and distribution?
Four developments currently decide what a wholesaler needs from its system. All four touch the same point: customers want to see today what used to be known tomorrow.
Self-service has become a channel, not a side stream
Business customers expect to see their own price online, their stock position and the status of their order. That is not a webshop beside the system, that is the system facing outward.
A stock figure refreshed once a night promises what you cannot deliver.
Stock no longer sits in one place
Several warehouses, stock held at a supplier, direct shipment and return flows all run side by side. The question is not how much you have, but how much you have where, and how much of it is already committed.
Count only at total level and you will regularly sell something that exists but is not available.
Price is an agreement per customer, not a list
Volume tiers, annual agreements, promotions and customer-specific discounts pile up. With purchase prices that move, margin per order line becomes the only reliable gauge.
Without margin at line level you steer on revenue and learn the result at year-end.
Customers ask for product data you do not record today
European rules on packaging, origin and product information are being phased in and pass down into trade. The data they require is rarely complete in the item file.
Your item data has to become richer than your current system asks of you.
Which ERP systems run in wholesale?
These are the systems you meet most often in Dutch wholesale. They differ mainly in how much warehouse logic they carry themselves and how much they leave to a separate system.
What it was built for and what to watch
| System | What it was built for | What to watch |
|---|---|---|
| Exact | Dutch trading companies, with the finance side and stock close together. | Strong on administration. With complex warehouse processes a separate system usually appears beside it. |
| Dynamics 365 Business Central | Trade across several locations or countries, where links to other software matter as well. | Broadly applicable, so the configuration decides the result. Ask who maintains that configuration later. |
| SAP Business One | Wholesalers working in an international chain or belonging to a larger group. | The choice often comes from the chain. Check whether your own processes carry it too. |
| Odoo | Organisations that want to configure and connect a lot themselves, with a team able to do it. | The freedom is both the gain and the risk. Without in-house knowledge that freedom moves to your partner. |
| Separate warehouse system | Warehouses with scanning, zoning and picking routes the ERP system does not know as standard. | Two systems means an integration. Agree who maintains it when either side changes. |
Not an exhaustive list and not a recommendation. We hold no partnership with vendors, so we have no stake in which name you choose.
Where does it pinch at each stage of growth?
A wholesaler hits different limits than a manufacturer, and hits them at predictable moments. Knowing which stage is coming leads to a different choice than looking only at today.
Per stage of growth
| Employees | What happens | Where it then pinches |
|---|---|---|
| Up to about 25 | One warehouse, a manageable range. Ordering on experience and instinct, prices in a list. | Little, until the range grows faster than the overview. Saying no then shows up first at the customer. |
| 25 to 100 | The range broadens, a webshop or customer portal arrives, more suppliers and longer lead times. | What is online and what is in the warehouse drift apart. Every correction costs a phone call. |
| 100 to 250 | A second location or an external warehouse, direct shipments, customer-specific pricing at scale. | Stock per location and margin per order line. Both usually sit outside the system, in a file of their own. |
| Above 250 | Several countries, sometimes an acquisition with a second system, own brands alongside traded goods. | Item management and consolidation. Two sites call the same item something different, and that works through into buying power. |
Most wholesalers buy a system for the range they carry today.
That holds until the first extra location, the first customer portal or the first direct shipment. Ask every candidate what happens when stock sits in two places and the customer wants to see online what is available.
Four questions that test the next stage
Put them to every candidate, in this order. If the answer to the first stays vague, the other three tell you little.
- What does this system show a customer online when the same item sits in two locations and part of it is committed?
- How does this system record a customer-specific price agreement, and who can change it later?
- Where do I see margin per order line, and does it use the actual purchase price?
- What does it take to add another warehouse or a direct shipment flow?
Frequently asked questions
- Which ERP system suits a wholesaler?
That depends on your warehouse processes and your pricing structure. Simple storage is covered by the stock module of a broad system; scanning, zoning and picking routes usually bring a separate warehouse system alongside.
So do not start from the system name but from how your orders leave the warehouse. That rules out more candidates than any feature list.
- What is the difference between ERP and WMS?
ERP runs the order, the stock position and the finances. A WMS runs the warehouse itself: where something sits, who picks it and in what order.
Every ERP system has stock functions, so the question is not whether it is possible. The question is whether your warehouse has logic the ERP system does not know.
- Does a wholesaler need a separate warehouse system?
Only if the warehouse has logic of its own: scanning by location, zoning, picking routes or tasks that span several orders. Without that logic a second system mostly produces an integration.
Weigh in that two systems need two owners. An integration without an owner is an outage waiting for its moment.
- How do you connect a webshop to your ERP system?
Through an integration that pushes items, prices and stock outward and brings orders back. Judge not whether it is possible, but how often it runs and who maintains it.
The difference between real time and once a night is exactly the difference between a customer who orders and a customer who calls.
- When is a wholesaler ready for a new ERP system?
When stock positions are structurally wrong, price agreements are kept outside the system, or nobody can show margin per order without a file of their own.
Growth is rarely the direct trigger. More often it is a second location or a customer portal that suddenly leaves the system in the wrong shape.
