What You're Actually Building
When a founder says "I want to build a SaaS product," they usually mean one of these:
- A web application where businesses sign up, get their own workspace, and pay monthly. - A platform with different user roles (admin, team member, customer), subscription billing, and a dashboard. - A mobile app with a web-based admin panel and backend API. - Some combination of the above, possibly with AI features.
All of these share the same foundational components: user authentication, multi-tenant data isolation, subscription billing, role-based access control, and an admin dashboard. The business-specific features layer on top of this foundation.
Understanding this is important because it sets realistic expectations about scope. Even a "simple" SaaS product needs these foundational systems built correctly — they're invisible to users but critical to operations.
Realistic Timelines
MVP (6-12 weeks). A functional product with core features, user authentication, basic subscription billing, and enough functionality to validate your business model with real users. This is not a prototype — it's a production-ready product that can accept payments and serve customers.
Post-MVP iteration (4-8 weeks). Based on real user feedback, you refine the UX, add the features users actually request (not the ones you assumed they'd want), and optimize the flows that matter most.
Growth phase (ongoing). New features every sprint, performance optimization, scaling infrastructure, and responding to market feedback. This is where a Growth Engineering Retainer makes sense.
Most founders underestimate the MVP timeline and overestimate what needs to be in the MVP. The goal of your first version isn't to have every feature — it's to get your core value proposition in front of real users as fast as possible.
What It Costs
MVP: $25K-$50K. This covers product strategy, UX design, architecture, development, testing, and deployment. The range depends on complexity — a straightforward B2B tool with 3-4 core features lands at the lower end. A marketplace with multiple user types, real-time features, and complex billing logic lands at the higher end.
Post-MVP iteration: $10K-$25K. Refinement based on user feedback, additional features, and optimization.
Ongoing development: $3K-$10K/month. Feature development, performance monitoring, scaling support, and strategy calls via a retainer.
These are fixed-price engagements. You know the cost before development begins. If scope changes during the project, we discuss it before your bill changes.
What's Included in the Build
Every SaaS product we build includes these foundational components:
Multi-tenant architecture. Each customer gets their own isolated workspace with their own data. Your database schema supports thousands of tenants without performance degradation.
Authentication and authorization. Secure sign-up/login flows, password reset, email verification, and role-based access control. Admins see admin features. Team members see their workspace. Customers see their portal.
Subscription billing. Stripe integration with multiple pricing tiers, free trials, usage-based billing options, promo codes, and automated invoicing. We handle the complex parts — prorations, failed payment recovery, subscription upgrades/downgrades.
Admin dashboard. You need visibility into your business. User management, subscription status, revenue metrics, feature usage analytics, and whatever operational data matters for your product.
Responsive design. Works on desktop, tablet, and mobile browsers. If your product needs a native mobile app (iOS/Android), we build that too.
CI/CD and monitoring. Automated deployment pipeline, error tracking, performance monitoring, and uptime alerts from day one. Not bolted on later — built into the foundation.
The Development Process
Week 1-2: Strategy and design. We define your value proposition, target market, pricing model, and MVP scope together. You get interactive prototypes showing exactly how the product will look and work. We finalize the technical architecture and database design. Nothing is built until you've approved the plan.
Week 3-10: Sprint-based development. Two-week sprints with demos every Friday. You see working software every two weeks and can adjust priorities based on what you learn. Each sprint delivers functional features, not wireframes or partial implementations.
Week 10-12: Testing and launch. Security audit, performance testing, production deployment, monitoring setup. Your product goes live with real infrastructure, not a staging server.
What to Look for in a Development Partner
Five things that matter more than portfolio screenshots:
Fixed pricing. If a partner can't give you a fixed price after a thorough scoping session, they either don't understand the project or don't want to commit to a number. Either way, your budget is at risk.
Code ownership. You should own 100% of the source code from day one. No proprietary frameworks, no vendor lock-in. If you want to hire your own team or switch partners tomorrow, you can.
Direct access to engineers. If your primary contact is a project manager who relays messages to developers, decisions will be slow and details will be lost in translation. The people building your product should be the people you talk to.
Proof of delivery. Case studies with real results — not just screenshots but measurable outcomes. How long did the build take? Did it ship on time? Are users actually using it?
Post-launch support. Building the product is half the job. What happens after launch when you need to iterate based on user feedback, fix the bug that only appears at scale, or add the feature your biggest customer is asking for?
The Biggest Mistake Founders Make
Trying to build everything at once. Your v1 doesn't need 30 features — it needs the 3-5 features that validate whether people will pay for your solution. Everything else can wait until you have real users telling you what they actually want.
Build the smallest version that delivers your core value proposition. Launch it. Get paying users. Then iterate based on reality, not assumptions.
