The verdict in three sentences
A custom client portal for a services SME in Toronto costs between 18,000 and 45,000 EUR net in 2026 depending on scope. The real return comes from a 30% reduction in support calls and emails, not the showcase effect. Below 18,000 EUR, you are buying a rebranded generic SaaS module, not an application that fits your processes.
What drives the price in 2026
A client portal is not a website: it is an authenticated application where each client finds their orders, documents and invoices. The budget depends mostly on the number of modules and the depth of integration with your ERP or billing tool.
| Item | Scope | 2026 range (EUR net) |
|---|---|---|
| Discovery & UX | Workshops, journeys, mockups | 2,500 - 5,000 |
| SSO authentication | Login, roles, MFA | 2,000 - 4,500 |
| Orders & tracking | Statuses, history, follow-ups | 4,000 - 9,000 |
| Document & invoice vault | Upload, versioning, download | 3,500 - 8,000 |
| Email/SMS notifications | Alerts, reminders, digests | 1,500 - 3,500 |
| ERP/billing integration | API, synchronization | 4,500 - 12,000 |
| QA & go-live | Testing, GDPR, training | 2,000 - 4,500 |
A Starter project (order tracking + documents) runs around 18,000-24,000 EUR net. A full project with real-time ERP integration and multichannel notifications reaches 38,000-45,000 EUR net.
Custom portal vs generic SaaS module
The question every director asks: why not just use a SaaS client portal at 90 EUR/month? Here is the honest comparison over a 3-year horizon.
| Criterion | Custom portal | Generic SaaS module |
|---|---|---|
| Upfront cost | 18,000 - 45,000 EUR net | 0 - 1,500 EUR |
| Monthly cost | 400 - 900 EUR (maintenance) | 90 - 400 EUR/month |
| 3-year total cost | 32,000 - 77,000 EUR | 3,200 - 15,000 EUR |
| Process fit | Total | Limited to options |
| ERP integration | Native, bespoke | Standard connectors |
| Data sovereignty | Hosting of your choice | Vendor servers |
| Scalability | Unlimited | Capped by vendor |
SaaS wins on raw cost. Custom wins as soon as your processes are specific, ERP integration is critical, or the client relationship differentiates your offer.
Timeline and maintenance
Budget 10 to 16 weeks from discovery to go-live for a standard portal. Maintenance runs 400 to 900 EUR/month: fixes, minor evolutions, monitoring, backups and security updates. It is a budget line to anticipate from the start, not a surprise.

Claire runs a 34-employee technical services SME in Toronto. Her team spends about 22 hours a week on the phone: "Where is my order?", "Can you resend the invoice?". At a 32 EUR loaded hourly cost, that is 704 EUR/week, roughly 36,600 EUR/year. A 28,000 EUR portal that absorbs 30% of those calls saves ~11,000 EUR/year of support time, plus maintenance (7,200 EUR/year). The portal pays for itself in a little over 2 years, not counting the professional image and client satisfaction.
FAQ
How much does a custom client portal really cost in Toronto in 2026?
Between 18,000 and 45,000 EUR net depending on the number of modules and ERP integration. An order-and-document tracking portal starts around 18,000-24,000 EUR net.
What is the development timeline?
Budget 10 to 16 weeks for a standard portal: 2-3 weeks of discovery, 6-10 weeks of development, 2-3 weeks of QA and go-live.
Is SSO really necessary?
Yes, as soon as your clients already use a company directory or other tools. SSO reduces forgotten passwords and secures access with MFA, for an added cost of 2,000 to 4,500 EUR.
What maintenance budget should I plan?
Maintenance of 400 to 900 EUR/month covers fixes, minor evolutions, monitoring and security. Plan it from the initial budget.
Can we start small and expand later?
Yes, it is even recommended: a Starter core at 18,000-24,000 EUR net, then modules added in batches. Custom development allows this gradual growth, unlike a closed SaaS.
