Client portal vs brochure website: ROI in 2026

Websites

The verdict in three sentences

A brochure website costs in 2026 between 5,000 and 15,000 EUR (excl. VAT); a client portal with a secure area between 15,000 and 45,000 EUR. The portal becomes profitable when self-service (documents, invoices, order tracking) cuts support tickets by 25 to 40%. For a services SME, the tipping point sits around a few hundred recurring requests per month, with ROI reached in 12 to 18 months.

Brochure or portal: feature comparison

The two solve different needs: one attracts prospects, the other serves and retains existing customers. Here is the 2026 comparison.

CriterionBrochure siteClient portal
Budget (EUR excl. VAT)5,000 - 15,00015,000 - 45,000
GoalAttract, convertServe, retain

Self-serviceNoDocuments, invoices, tracking
Delivery time4 - 8 weeks8 - 16 weeks
Maintenance/year600 - 2,000 EUR3,000 - 9,000 EUR
Support-ticket impactNeutral-25 to -40%

A portal is not a "big brochure site": it is an application with authentication, permissions and customer data.

The portal break-even threshold

A portal is justified by the costs it removes, not by its looks. Here is how to estimate the tipping point.

Monthly ticket volumeEstimated support cost/monthPortal relevant?
< 100 tickets< 1,500 EURNo, brochure site is enough
100 - 300 tickets1,500 - 4,500 EURWorth studying
300 - 600 tickets4,500 - 9,000 EURYes, likely ROI
600 - 1,000 tickets9,000 - 15,000 EURYes, fast ROI
> 1,000 tickets> 15,000 EURYes, priority

Simple rule: if the portal removes 30% of tickets at 15 EUR per handled ticket, compute the annual saving and compare it with the development budget.

Mini case study

Julien, head of an industrial-maintenance SME in Lyon (28 employees), handles 480 support tickets/month (invoice requests, intervention tracking, documents) at an average cost of 14 EUR per ticket, about 6,720 EUR/month. He invests 32,000 EUR (excl. VAT) in a self-service client portal. Result: -35% of tickets, about 2,350 EUR/month saved, plus response time divided by three. Annual saving: 28,000 EUR. The portal pays back in about 14 months, before counting the gain in satisfaction and retention.

FAQ

When is a brochure site really enough?

When the goal is to attract and convert prospects, with few recurring requests from existing customers. Below roughly 100 support tickets/month, a portal is hard to justify.

Why does a portal cost three times more?

Because it is an application: authentication, permission management, customer database, integrations (billing, CRM), hardened security. The 15,000 to 45,000 EUR budget reflects that complexity.

Can we start small and grow?

Yes, a recommended approach: first deliver a high-performance brochure site, then add a client area in modules (invoices, then tracking, then documents) as volume justifies it.

What is a portal's main source of gain?

The reduction of repetitive support tickets (-25 to -40%) and faster responses. Self-service frees teams from low-value tasks and improves satisfaction.

How long to build a client portal?

Between 8 and 16 weeks depending on integrations (billing, CRM, ERP) and the number of self-service features. An MVP focused on one function can ship faster.
