SaaS Development – Multi-Tenant, Billable, Ready to Scale

Multi-tenant means that many customer companies use the same software while their data stays strictly separated. Each tenant has its own users, roles, settings and content, while you roll out updates centrally for everyone. How strictly the separation is implemented technically, we determine based on your target audience and their requirements.

A SaaS launch with a core function, registration, tenant isolation and subscription billing typically falls under the Professional package from €8,000. Platforms with many modules, interfaces, single sign-on or special requirements for isolation and availability are quoted individually as Enterprise projects. You receive the exact quote after the free initial consultation – preferably at a fixed price when the scope is clearly defined.

That depends mainly on the scope of the first version. We recommend starting with a clearly limited core and adding further modules in stages after launch – that way you reach paying customers sooner. You receive a reliable schedule after the concept phase.

If it is still unclear whether customers will pay for your idea, an MVP is the cheaper test. As soon as the first customers are supposed to pay, you need the SaaS fundamentals: tenant isolation, billing, permissions and reliable operation. We often build both in stages – first the core, then the full subscription product on the same foundation.

We integrate a payment provider such as Stripe that covers plans, trial periods, credit cards, SEPA direct debit and invoices. Upgrades, downgrades, cancellations and failed payments run automatically, and your admin area shows the status of every customer. Please clarify tax questions regarding invoicing with your tax advisor.

We host SaaS products in data centers in the EU and implement encryption, backups, access logs and a permissions concept on the technical side. Because, as the provider, you usually process your customers' data on their behalf, you need, among other things, data processing agreements and suitable privacy notices. We deliver the technical foundations; you clarify the legal design with your data protection or legal counsel – this note does not replace legal advice.
