The verdict in three sentences
A distributor ordering portal in Amsterdam costs between 45,000 and 100,000 EUR in 2026, over a 4 to 6 month timeline. The heart of the project is negotiated pricing per distributor, real-time stock and the ERP integration that removes double entry. The return is mechanical: -40% order-taking time and +22% reorder rate thanks to 24/7 self-service.
What sets a distributor portal apart
Unlike an open B2B store, a distributor portal is closed and personalised: each distributor sees its own prices, terms, credit balance and history. Here is the typical breakdown of such a project.
| Item | 2026 range (EUR) | Timeline |
|---|---|---|
| Scoping + portal design | 7,000 - 15,000 | 3-5 wks |
| Distributor accounts + roles | 5,000 - 13,000 | 3-5 wks |
| Negotiated pricing per account | 8,000 - 20,000 | 4-7 wks |
| Real-time stock + ERP | 10,000 - 28,000 | 5-9 wks |
| Credit / payment terms | 5,000 - 13,000 | 3-5 wks |
| Testing + rollout | 4,000 - 11,000 | 2-4 wks |
Amsterdam day rates in 2026 sit slightly below Paris equivalents for equal seniority, an advantage for a budget-controlled industrial project.
| Profile | 2026 day rate (EUR) | Role |
|---|---|---|
| Project manager | 600 - 800 | Scoping, delivery |
| Back-end developer | 600 - 850 | ERP, pricing, stock |
| Front-end developer | 550 - 750 | Distributor journey |
| ERP integration expert | 680 - 900 | Real-time flows |
ROI: order-taking time
The main gain of a distributor portal is removing manual entry on the supplier side. Here is the estimated impact on a manufacturer handling a moderate order volume.
| Metric | Before portal | After portal |
|---|---|---|
| Avg time / order | 15 min | 9 min |
| Share of online orders | 20% | 70% |
| Entry errors | 6% | 1.5% |
| Reorder frequency | base | +22% |
| Sales-admin workload | base | -35% |
Mini case study
Nadia, sales director of a food manufacturer in Amsterdam (110 distributors, 9,000 orders/year), has each order handled by her sales-admin team in 15 minutes on average. She invests 58,000 EUR in a portal delivered in 5 months.
By moving 70% of orders online, average handling time drops to 9 minutes: across 6,300 migrated orders, that is 630 hours saved per year, about 0.4 FTE of sales-admin. Reordering rises 22% thanks to self-service. Estimated payback: under 15 months, before counting fewer entry errors.

FAQ
What is the difference between a distributor portal and an open B2B store?
The portal is closed: each distributor logs in to see its negotiated prices, credit balance and history. An open B2B store accepts new accounts self-service, with more standardised price lists.
Is ERP integration mandatory?
Not mandatory but strongly recommended: without it, stock and prices must be updated manually, which cancels much of the time saved. It is the item that pushes the budget toward the top of the range.
Can we manage credit limits and payment terms?
Yes, the portal shows each distributor's credit balance and can block an order above a ceiling. Negotiated payment terms (30, 45, 60 days) are also built in.
How soon is the portal operational?
Between 4 and 6 months depending on pricing complexity and the ERP. A pilot with about ten distributors can start earlier to validate the flows before general rollout.
Is the -40% order-taking gain realistic?
Yes, once most distributors order online. The gain comes from removing manual entry and reducing back-and-forth checks on the sales-admin side.
