The verdict in three sentences
A custom web platform (multi-actor portal, internal marketplace) in Dubai sits between 60,000 and 150,000 EUR in 2026. Price rises with the number of user roles, real time and integrated payments: multi-tenant architecture alone adds 15 to 25 %. Beyond the build, budget a cloud infrastructure of 300 to 1,500 EUR/month from launch.
2026 ranges by platform level
A platform differs from an application in its multi-actor dimension: several profiles interact (admin, suppliers, customers). Each additional role multiplies screens, permissions and rules.
| Platform type | Characteristics | 2026 range (EUR) | Timeline |
|---|---|---|---|
| 2-role portal | Admin + users, no payment | 60,000 - 85,000 | 4-5 months |
| 3-role platform | + suppliers / partners, workflow | 85,000 - 120,000 | 5-7 months |
| Transactional marketplace | Payments, commissions, real time | 120,000 - 150,000+ | 6-8 months |
| Platform extension | New module, public API | 25,000 - 50,000 | 2-3 months |
These amounts are a 2026 order of magnitude. Real time (messaging, live notifications, position tracking) typically adds 10 to 20 %, as it demands a more exacting event-driven architecture.
What really drives the ticket
Four levers explain most of the gap between 60,000 and 150,000 EUR. Identifying them early lets you decide before signing.
| Lever | Impact on cost | Option to reduce |
|---|---|---|
| Multi-tenant architecture | +15 to 25 % | Single-tenant if one client |
| Payments & commissions | +12,000 to 30,000 EUR | Defer to V2 |
| Real time | +10 to 20 % | Periodic refresh |
| Full build vs no-code | -30 to 50 % in no-code (MVP) | Hybrid to validate fast |
The typical team on this kind of project includes a product owner, two developers and a UX designer, over 4 to 8 months. It is this mobilisation, not the page count, that sets the budget.
Mini case study
Karim, founder of an artisan-to-client matching platform in Dubai, wants to launch a 3-role portal (admin, artisans, individuals) with messaging and deposit payment. The agency quotes a platform at 108,000 EUR over 6 months, plus 650 EUR/month cloud infra.
To control risk, he chooses a 2-role MVP (admin + artisans) at 72,000 EUR, deferring the deposit payment (estimated 18,000 EUR) to V2. This cuts his initial ticket by 33 % and lets him validate adoption before investing in the transactional module. Target: 40 active artisans before unlocking V2.

FAQ
Why does multi-tenant cost more?
Because each client's data must be isolated while sharing the technical base. This adds 15 to 25 % to the build and complicates security. Only pay for it if you genuinely serve several distinct organisations.
Can you start a platform in no-code?
Yes for a low-volume MVP: no-code saves 30 to 50 % and a few weeks. But beyond a few hundred active users or fine business rules, migrating to custom becomes necessary and must be budgeted.
How much for cloud infrastructure?
Between 300 and 1,500 EUR/month in 2026 depending on traffic, real time and storage. A nascent platform often starts around 300-600 EUR/month, then scales with load. It is a running cost, separate from the build.
Do you have to integrate payments at launch?
Not necessarily. If your model relies on matching, you can launch without transactions and add payments in V2. This removes 12,000 to 30,000 EUR from the initial ticket and speeds time-to-market.
What is a realistic timeline for a transactional marketplace?
Expect 6 to 8 months for a 120,000 to 150,000 EUR scope. Real time and payments demand a long QA phase. Trying to deliver in 4 months exposes flaws on the most sensitive part: money.
