What it costs to build a SaaS product
SaaS costs more than the same features built for one company, because you are also building signup, billing, tenancy isolation and support tooling for customers you have never met.
Outcomes
- Budget for the product and the platform around it
- A first paying tenant scoped separately
- Running cost per tenant modelled
- An indicative estimate in minutes
Pricing
Where it is used
Focused MVP SaaS
One workflow, self-service signup — €55,000 to €100,000.
Commercial SaaS

What we deliver
- Tenancy model and isolation requirements
- Billing complexity and metering
- Onboarding and support tooling
- Compliance expectations of your buyers
- Infrastructure and uptime targets
Who this is for
- Founders costing a first commercial release rather than a demo.
- Established companies productising an internal system for external customers.
How delivery runs
- 01
Scoping
One to two weeks on the real workflow, systems and data. Output is a written scope and an indicative band.
- 02
Phased plan
The first usable release is identified explicitly so spend produces something usable early.
- 03
Fixed first phase
Phase one is quoted as a fixed price where scope allows; later phases are re-estimated with real velocity data.
- 04
Change log
Anything added after sign-off is estimated and scheduled in writing, so the budget never moves quietly.
Realistic timeline
Weeks 1–3
Tenancy, billing and roadmap decisions.
Weeks 4–14
Commercial first release with billing and onboarding.
Months 4–6
Enterprise features driven by actual sales conversations.
Build or buy
Buy something existing when
- Use existing billing, authentication and email infrastructure rather than building them
Build custom when
- The product logic itself, the data model and the workflows customers pay for
Nearly every SaaS budget improves by buying the plumbing and building only the differentiated part.
What moves the price
Multi-tenancy model
Shared-schema tenancy is cheaper to build and operate; isolated databases per customer cost more up front and in running.
Billing and plans
Subscriptions, usage metering, trials, proration and tax handling are a substantial subsystem of their own.
Onboarding and administration
Self-service signup, invitations, roles and tenant administration are frequently omitted from first estimates.
Compliance expectations
Enterprise buyers ask for audit logs, SSO, data residency and security documentation — each is real engineering.
Where projects go wrong
Budget set before scope
A number agreed before discovery is a guess. We give a band after a short scoping phase and narrow it once the workflow and integrations are documented.
Data migration priced last
Legacy data is rarely as clean as expected. We survey the actual export during discovery rather than assuming it at the end.
FAQ
Questions buyers ask
Can we start smaller?+
Yes, and you should. Prove one workflow with paying customers before building tiers and partner programmes.
What are the running costs?+
Infrastructure, support and continuous development — typically 20 to 30 percent of build cost annually for an active product.
