The verdict in three sentences
When sales administration spends its days answering "where is my order?", a customer portal connected to the ERP is the most profitable investment for the team. In 2026, an order tracking portal for a manufacturer costs EUR 32,000 to 65,000 (excl. VAT), ships in 4 months and cuts inbound calls by about 50%. For a 6-person team in Berlin, that frees 1.5 FTE, about EUR 70,000 a year.
What an industrial customer portal includes
The portal gives customers self-service access, 24/7, to the information they currently request by phone or email. Data comes straight from the ERP, with no double entry.
| Feature | What the customer sees | Source |
|---|---|---|
| Order status | Received, in production, shipped, delivered | ERP, updated every 15 min |
| Confirmed lead time | Planned delivery date and any changes | ERP planning |
| Delivery notes | Downloadable PDFs and carrier tracking numbers | ERP and carrier API |
| Invoices and credit notes | History, due dates, payment status | Accounting |
| Technical documents | Material certificates, compliance sheets, manuals | DMS |
| Reorder | Repeat a past order in one click | Customer catalogue |
| Multi-user | Customer's buyers, accountants and warehouse staff | Permission management |
The most used feature remains the confirmed lead time: in a well-designed portal, any date change triggers an automatic email to the customer, which eliminates most follow-up calls.
Customer portal pricing in 2026
The budget depends mainly on the ERP (standard connector or custom development), the number of accounts and online ordering features.
| Component | Content | 2026 price (excl. VAT) |
|---|---|---|
| Portal core | Authentication, accounts, permissions, dashboard | EUR 13,000 to 20,000 |
| ERP connector | SAP Business One, abas, proALPHA, Microsoft Dynamics, sync | EUR 9,000 to 22,000 |
| Documents | Delivery notes, invoices, certificates as PDF | EUR 3,500 to 6,500 |
| Notifications | Lead time change, shipment, invoice issued | EUR 2,200 to 4,500 |
| Online ordering | Reorder, customer catalogue, negotiated prices | EUR 5,500 to 13,000 |
| Total | Depending on scope and ERP | EUR 32,000 to 65,000 |
| Maintenance and hosting | Monitoring, fixes, updates | EUR 450 to 1,000/month |
The ERP connector often represents a third of the budget. An ERP with a documented API cuts this item by 30 to 40%.
How to calculate ROI
The calculation rests on freed-up sales administration time, plus gains that are harder to quantify: customer satisfaction, fewer order errors, a stronger image against competitors.
| Indicator | Before the portal | After 6 months |
|---|---|---|
| "Order status" calls per week | 300 | 140 to 160 |
| Average call duration | 6 min | 6 min |
| Sales admin time spent per week | 30 h | 14 to 16 h |
| Invoice copy requests per month | 120 | 15 to 25 |
| Active account adoption rate | 0% | 45 to 60% |
| Average response time to customer | 4 h | Immediate |
Adoption depends on support: a personalized invitation email, a 2-minute tutorial and a reminder from sales reps usually reach 50% active accounts within 6 months.

Nathalie, head of sales administration at a 220-employee mechanical components manufacturer in Berlin, manages 6 people who take 300 calls a week and about 120 invoice copy requests a month. The 800 customer accounts mostly call about lead times.
Chosen project: portal at EUR 50,000 (core, SAP Business One connector, documents, notifications) plus EUR 750 a month, i.e. EUR 59,000 in year one. Gains: 50% fewer calls and automated invoice copies free 1.5 FTE, about EUR 70,000 a year of time redeployed to quote follow-up. In year one, with gradual adoption, the real gain is about EUR 46,000. The project pays back in 14 months, then returns about EUR 61,000 net a year, as a 2026 order of magnitude.
FAQ
Do we need to change ERP to get a customer portal?
No, the portal connects to the existing ERP through an API or the database. The connector costs EUR 9,000 to 22,000 depending on how open the ERP is.
Is the data real time?
Statuses sync every 5 to 15 minutes, which is enough for order tracking. Instant sync is possible for an extra EUR 2,200 to 5,500.
How long does it take to launch?
Allow 4 months: 3 weeks of scoping, 10 weeks of development and 3 weeks of pilot with 20 to 30 customers before general release.
Will customers actually use it?
With a personalized invitation and sales rep support, 45 to 60% of active accounts use it after 6 months. Large customers, who generate the most calls, adopt first.
Is the portal secure and GDPR compliant?
Yes: strong authentication, per-customer and per-user permissions, access logs and hosting in Germany. Each customer sees only its own orders.
