The verdict in three sentences
A B2B ordering portal for an industrial manufacturer in Amsterdam costs between 35,000 and 85,000 EUR in 2026, technical catalogue and EDI included. The real ROI is operational, not commercial: -50% order-processing time and a collapse in data-entry errors. Plan for 5 to 8 months of delivery and roughly 550 EUR/month in support.
What an industrial ordering portal covers
A manufacturer does not sell like a consumer e-shop: technical catalogue with datasheets, references by family, minimum order quantities, quote-before-order, sometimes EDI with key accounts. Here is how the budget splits.
| Line item | 2026 range (EUR) | Detail |
|---|---|---|
| Discovery + pro portal UX | 5,000 - 10,000 | Buyer journey, customer accounts, roles |
| Technical catalogue | 7,000 - 16,000 | Datasheets, docs, families, units, MOQ |
| Quote + order engine | 6,000 - 15,000 | Quote request, approval, conversion |
| EDI interface | 8,000 - 22,000 | Order/invoice exchange with key accounts |
| ERP/PIM connector | 6,000 - 15,000 | Sync products, prices, stock, orders |
| QA + training | 3,000 - 7,000 | Testing, migration, team onboarding |
| Project total | 35,000 - 85,000 | Operational portal |
EDI is the industry-specific line: if your large customers (distributors, buying groups) require it, budget 8,000 to 22,000 EUR depending on formats (EDIFACT, XML) and partner count.
The operational ROI in numbers
The portal is justified mainly by internal gains. Here is a calculation model for a manufacturer receiving 300 orders/week.
| Indicator | Before portal | After portal | Gain |
|---|---|---|---|
| Avg entry time/order | 8 min | 2 min | -75% |
| Manually handled orders/wk | 300 | 90 | -70% |
| Entry errors/month | 45 | 8 | -82% |
| Processing cost/order | 4.50 EUR | 1.60 EUR | -64% |
| Sales-admin FTEs | 2.5 | 1.3 | -1.2 FTE |
On 300 orders/week, moving from 4.50 to 1.60 EUR processing cost saves roughly 45,000 EUR/year, before counting credit notes and disputes avoided by fewer errors.
Mini case study
Els is operations director at a technical-parts manufacturer in Amsterdam: 180 trade customers, 300 orders/week, an in-house ERP. She invests 58,000 EUR in a portal with technical catalogue, quotes and EDI for her 3 biggest customers, plus 550 EUR/month support. Within 10 months, 70% of orders flow through the portal. Annual processing savings (~45,000 EUR) plus fewer credit notes (~12,000 EUR) deliver payback in about 14 months.

FAQ
What is EDI and is it mandatory?
EDI exchanges orders and invoices automatically with key accounts. It is not mandatory but often required by buying groups. Budget 8,000 to 22,000 EUR depending on partners.
Can we start without EDI and add it later?
Yes, and it is recommended: deliver the catalogue + order portal first (3-4 months), then connect EDI customer by customer per commercial priorities.
Does the portal handle quotes before orders?
Yes. In industry many sales go through a quote. The quote-to-order engine costs 6,000 to 15,000 EUR depending on approval rules.
How does it connect to our ERP?
Via a two-way connector (products, prices, stock, orders) priced 6,000 to 15,000 EUR. A PIM upstream eases management of technical datasheets.
What is the annual maintenance budget?
Roughly 6,600 EUR/year (550 EUR/month) for routine support. Major features (new EDI flows, modules) are quoted separately.
