The verdict in three sentences
A multi-tenant SaaS is not just a web app: it is a platform that isolates each customer's data while sharing code and infrastructure. In Dublin in 2026, a market-ready V1 costs from 280,000 to 480,000 TND-equivalent. The fatal mistake is confusing a single-tenant pilot MVP with a scalable V1: the first validates the market, only the second absorbs growth.
Budget for a market-ready SaaS V1
A sellable V1 requires four inseparable foundations: isolate tenants, manage subscriptions, deliver business value and steer it all. Here is the cost structure observed in Dublin in 2026, at a 900 to 1,400 TND day rate.
| Brick | Scope | Budget TND |
|---|---|---|
| Multi-tenant architecture | Data isolation, tenant provisioning | 90,000 |
| Accounts / roles / recurring billing | Auth, permissions, subscriptions | 70,000 |
| Core business module | The feature justifying the subscription | 130,000 |
| Admin back office + analytics | Supervision, metrics, support | 45,000 |
| Total scalable V1 | 280,000 – 480,000 |
A single-tenant pilot MVP can start around 150,000 to 200,000 TND, but multi-tenant isolation will have to be rebuilt before opening to paying customers.
Pilot MVP vs scalable V1, and infra costs
Scalability is paid upfront in architecture, then at growth in infrastructure. This table distinguishes the two stages and projects infra cost by tenant count.
| Dimension | MVP 1 tenant | Scalable V1 |
|---|---|---|
| Build budget | 150,000 – 200,000 TND | 280,000 – 480,000 TND |
| Data isolation | Basic | Strict per tenant |
| Recurring billing | Manual | Automated |
| Infra at 10 tenants | ~800 TND/mo | ~1,500 TND/mo |
| Infra at 100 tenants | untenable | ~6,000 TND/mo |
| Annual run | 15% of build | 15% of build |
The SaaS pricing model (e.g. 3 tiers: free trial, starter, pro) must be defined BEFORE the build: it drives recurring billing and therefore the architecture.
Mini case study
Sonia runs a Dublin software vendor targeting accounting firms. She hesitates between a 180,000 TND MVP and a 400,000 TND scalable V1. Her target market: 220 firms, target price 290 TND/month per firm. 18-month goal: 60 paying customers, i.e. 17,400 TND MRR (208,800 TND/year). With the scalable V1, infra stays under 6,000 TND/month and run at ~60,000 TND/year; gross margin exceeds 65%. The 400,000 TND build is repaid in about 27 months of MRR, after which each new firm is near-pure recurring profit. The MVP would have delayed commercialization for lack of multi-tenant isolation.

FAQ
How much does a multi-tenant SaaS platform cost in Dublin in 2026?
From 280,000 to 480,000 TND-equivalent for a market-ready V1 including multi-tenant architecture, recurring billing, core business module and back office. A single-tenant pilot MVP starts around 150,000 TND.
Should we start with an MVP or go straight to a V1?
The MVP validates the market cheaply, but a single-tenant MVP will need re-architecting before opening to paying customers. If the market is already validated, the scalable V1 avoids that double investment.
How much does infrastructure cost at growth?
As a 2026 order of magnitude, about 1,500 TND/month at 10 tenants and 6,000 TND/month at 100 tenants. Multi-tenant architecture shares infra, keeping the marginal cost per customer low.
How do we define SaaS pricing?
Three tiers work well: free trial, starter and pro. Pricing must be set before the build because it determines the recurring-billing logic and per-tenant quotas.
How long for a sellable V1?
Between 18 and 24 weeks in Dublin in 2026, in sprints, with a pilot tenant in production by week 12 to gather feedback before commercial launch.
