Service Description
Launch a production-ready B2B SaaS application in four weeks with the technical foundation needed to support real customers, future features, and continued growth.
This fixed-scope engagement is designed for funded founders, early-stage startups, and non-technical operators who need more than a basic prototype. You will receive a fully engineered SaaS MVP with scalable architecture, secure authentication, maintainable data models, and the core workflows required to begin onboarding users.
The goal is not to pack every possible feature into the first release. The goal is to build the right foundation, deliver the most important product functionality, and launch a dependable application without unnecessary agency overhead.
What’s Included
Week 1: Architecture and Data Modeling
We begin with a one-on-one architecture and product-mapping session to define your users, organizations, permissions, core workflows, and technical requirements.
Deliverables include:
Application architecture plan
Relational database design
Entity relationship diagram
User and organization structure
Development environment configuration
Initial deployment and infrastructure strategy
Week 2: Core Systems and Authentication
The core application framework and user experience are developed, including:
Secure user authentication
Organization or workspace setup
Multi-tenant account structure, when required
Core user dashboard
Protected application routes
Foundational role and permission controls
Week 3: Product Workflows and Billing
Up to three core operational features or product workflows are developed based on the agreed project scope.
This phase may also include:
Stripe subscription integration
Checkout and billing portal connections
Subscription-status handling
Third-party API integrations
Transactional email workflows
Administrative controls
Week 4: Deployment and Handoff
The application is prepared for production use and deployed to the agreed hosting environment.
Final delivery includes:
Production deployment
Environment and secret configuration
Final security and dependency review
Core workflow testing
Source-code handoff
Technical documentation
One week of post-launch stabilization support
Important Scope Notes
This service is intended for focused B2B SaaS MVPs with a clearly defined initial feature set. The engagement includes up to three primary operational workflows.
Large data migrations, advanced artificial intelligence systems, native mobile applications, highly regulated compliance requirements, complex real-time systems, or unusually extensive third-party integrations may require a larger engagement.
Any requirements outside the agreed scope will be discussed before development begins.
Security & Governance Standards
All API keys, third-party tokens, and deployment secrets are managed under strict, isolated human control and never exposed to public repositories or external cloud AI retention paths. Every line of production code undergoes manual human review and dependency verification prior to deployment.
