The verdict in three sentences
For a manufacturer selling 180,000 appliances a year, a portal where distributors and repairers file faults and order parts costs EUR 30,000 to 60,000 and ships in 4 to 6 months. The payoff is measured per claim: handling cost drops from roughly EUR 22 to EUR 9 once data entry, eligibility checks and parts ordering are automated. The item that blows budgets is the ERP connection, so scope it before anything else.
What the portal must contain, module by module
The portal serves three audiences: distributors (retail chains, resellers), authorised repairers and the internal after-sales team. Each module carries a different cost and impact.
| Module | Function | Indicative 2026 budget (EUR, excl. VAT) | Impact on cost per claim |
|---|---|---|---|
| Serial number registration | Checks sale date and warranty period | 4,000 to 7,000 | Removes 80% of manual checks |
| Guided fault reporting | Form per product family, photos, fault code | 5,000 to 9,000 | Complete claims at first entry |
| Claims approval workflow | Accept, reasoned refusal, request for info | 6,000 to 12,000 | Decision time from 6 days to 48 h |
| Spare parts ordering | Catalogue per model, exploded views, stock | 5,000 to 10,000 | Fewer wrong part numbers |
| Repairer reimbursement | Flat-rate scale, accounting export | 3,000 to 6,000 | Paid in 15 days instead of 45 |
| ERP connection | Customers, items, stock, credit notes | 6,000 to 14,000 | No more double entry |
| Quality dashboard | Failure rate per model and batch | 2,000 to 4,000 | Early detection of faulty series |
A core version (registration, reporting, workflow, file-based ERP export) lands around EUR 30,000. The full version, with real-time ERP API, parts ordering and quality dashboard, reaches EUR 55,000 to 60,000.
The return on investment calculation
The key ratio is the fully loaded cost of a warranty claim: data entry time, follow-up calls, proof of purchase checks, wrong parts shipped. A 4% warranty return rate on 180,000 appliances means about 7,200 claims a year.
| Indicator | Before portal | After portal | Annual difference |
|---|---|---|---|
| Warranty claims per year | 7,200 | 7,200 | Stable |
| Handling cost per claim | EUR 22 | EUR 9 | EUR 93,600 saved |
| Average decision time | 6 days | 48 h | Higher customer satisfaction |
| Parts shipped in error | 9% | 3% | About 430 shipments avoided |
| Incomplete claims | 35% | 8% | Fewer follow-up calls |
| Repairer reimbursement time | 45 days | 15 days | More loyal network |
With a EUR 45,000 portal and maintenance at 15 to 20% per year (EUR 6,750 to 9,000), the EUR 93,600 saving pays back the investment in under 7 months of operation.
Typical 4 to 6 month timeline
Month 1: workshops with after-sales, three distributors and three repairers, ERP flow mapping. Months 2 and 3: core module development, mock-ups validated in the field. Month 4: ERP connection and acceptance testing. Month 5: pilot with 10 to 15 Berlin and Brandenburg repairers. Month 6: rollout to the national network. Plan the import of serial number history (often 3 to 5 years of sales) in month one: it is the data that enables automatic eligibility.

Jonas, head of after-sales at a small appliance manufacturer in Berlin, handles 7,200 claims a year with four agents. He picks the EUR 48,000 version with API-based ERP connection. Handling saving: 7,200 × (22 - 9) = EUR 93,600 per year. With maintenance at EUR 8,000 a year, net first-year gain is 93,600 - 48,000 - 8,000 = EUR 37,600. The four agents stay: two move to batch quality analysis, which has already isolated a faulty thermostat series.
FAQ
Custom portal or the service module of an off-the-shelf suite?
Standard service modules cost EUR 50 to 150 per user per month but handle external repairer networks and flat-rate scales poorly. Above 5,000 claims a year, custom usually pays off within 2 to 3 years.
How do we connect the portal to the ERP?
By API if the ERP offers one (budget EUR 6,000 to 14,000), otherwise by scheduled file exchange, cheaper (EUR 2,000 to 4,000) but with a lag of a few hours.
Will repairers actually use it?
Yes if the portal pays them faster: going from 45 to 15 days for reimbursement is the decisive argument. A 4-week pilot with 10 to 15 workshops lets you fix usability before rollout.
Which GDPR obligations apply?
The portal processes end customer contact data: set a retention period (often warranty length plus 2 years), host in the EU and keep the records of processing up to date.
Can we add paid extended warranties?
Yes, as a later module at EUR 5,000 to 9,000 with online payment. A 3 to 6% uptake among registered appliances creates a recurring revenue line.
