Subscriptions
Robust server-side logic and backend architecture for cloud-based IT products — multi-tenant data, secured accounts, recurring billing, and a launch on the cloud provider you prefer.
Engineering robust server-side logic and backend architecture for cloud-based IT products.
Designing multi-user database architecture, securing user accounts, and building subscription billing models.
A highly scalable web application engineered to handle peak traffic and custom business logic.
Environment configuration, final testing, and launch on AWS, DigitalOcean, or GCP.
Everything in the 1 500 € package
The backend is where a subscription product lives or dies. This scope covers the data model, the account boundary, the billing cycle and the environment it all runs in.
- Multi-user database architecture with tenant isolation
- Account registration, authentication and session security
- Role and permission model for teams and admins
- Subscription billing models: plans, trials, upgrades and cancellations
- Recurring payment provider integration with webhook handling
- Custom business logic implemented server-side, not in the browser
- REST or GraphQL API surface with documented endpoints
- Architecture designed to hold up under peak traffic
- Separate development, staging and production environments
- Environment configuration and secrets documented, never hard-coded
- Final testing pass and launch on AWS, DigitalOcean or GCP
- Full source code repository transferred with handover notes
How a platform gets built
Domain & data modelling
We map your entities, tenants and access boundaries first. Getting this wrong is the single most expensive mistake a SaaS product can make, so it is settled before any feature is written.
Accounts & security
Registration, authentication, sessions, password handling and a role model that matches how your customers actually organise their teams.
Billing engine
Plans, trials, upgrades, downgrades and cancellations, with provider webhooks handled idempotently so a retried event never double-charges.
Business logic & API
Your custom rules implemented server-side and exposed through a documented API surface your front-end or partners can build against.
Environments, testing & launch
Development, staging and production configured separately, a final testing pass, then launch on AWS, DigitalOcean or GCP with the repository handed over.

SaaS platform FAQ
This package is the backend: server-side logic, database architecture, accounts and billing. A front-end can be scoped alongside it — often as a landing page for marketing plus an application UI — and is quoted as its own clearly separated item.
You do, directly to AWS, DigitalOcean or GCP, on accounts in your company’s name. We configure the environments inside your accounts so the bill, the access and the ownership all sit with you from day one.
Through architecture rather than promises: stateless application processes, indexed queries, connection pooling and a deployment shape that can scale horizontally. Concrete load targets are agreed during scoping so the design can be checked against them.
Yes. Many products launch with a single plan and one user role, then grow. Say so during scoping and the billing model is built to extend rather than be rewritten later.
The package ends at handover, with everything documented so your team or another supplier can continue. Ongoing work is available and quoted per request under the same fixed-scope terms.
