I have sat through enough introductory calls to know the first question founders ask. It is always some version of “how much will this cost?” I get it. You are budgeting, fundraising, or spending your own money. You need a number. But the honest answer — the one that actually helps you plan — is not a single figure. It is a framework for understanding what drives the number, so you can control it.
At Phenomenon Studio, we have now shipped over 40 digital products. SaaS platforms, ERP modules, fintech dashboards, healthtech patient portals, edtech learning platforms. The cost range is wide because the scope range is wide. In this article, I am going to give you the real numbers from our project history, explain what drives them, and walk through the questions we ask on every introductory call. No ranges pulled from industry averages. No “it depends” without the “depends on what.” Just what we have actually seen, quoted, and billed.
If you are evaluating agencies, comparing build-vs-buy decisions, or trying to budget for a fundraise, this is the article I wish someone had written before I started managing these conversations. We are a web design agency that grew into full-stack product development, so we have seen the full spectrum — from marketing sites to multi-tenant SaaS platforms with compliance requirements. That perspective shapes everything below.

Let me skip the industry benchmarks and give you our actual project data. These are real ranges from work we delivered, not survey averages or rate-card estimates. I have anonymized client names but kept the scope descriptions specific enough to be useful.
SaaS MVP (single-purpose tool, basic auth, one core workflow, no compliance): $45,000 – $75,000. Timeline: 10–14 weeks. Example: A construction project management tool with task assignment, file uploads, and a client-facing dashboard. Tech stack: React front end, Node.js back end, PostgreSQL, deployed on AWS.
SaaS MVP with payment infrastructure and multi-tenant architecture: $80,000 – $150,000. Timeline: 14–20 weeks. Example: A subscription-based analytics platform for ecommerce brands with Stripe integration, role-based access, and white-label reporting. Tech stack: Next.js front end, Laravel back end, MySQL, Redis for caching, Vercel + AWS deployment.
Production-grade SaaS with compliance (HIPAA, SOC 2, or KYC/AML): $180,000 – $350,000+. Timeline: 6–9 months. Example: A fintech dashboard with identity verification, transaction monitoring, audit trails, and bank-grade encryption. Tech stack: React, Python/Django back end, PostgreSQL with encryption at rest, Sumsub integration, AWS with VPC isolation.
Custom ERP module or full-suite ERP: $60,000 – $250,000. Timeline: 4–8 months. Example: A manufacturing ERP with inventory management, production scheduling, and supplier portal. Tech stack: Angular front end, Java Spring Boot back end, Oracle or PostgreSQL, on-premise or hybrid cloud deployment.
The median project across all categories in 2025 landed at $125,000. But I want to stress something that gets lost in these summaries: the range within each category is driven by specific, identifiable factors, not by us pulling numbers out of the air. Here are the four variables that moved the budget on almost every project we scoped.
Variable 1: Integration Surface Area
Every third-party integration adds development time plus ongoing maintenance complexity. A SaaS product with zero integrations (standalone tool) is the cheapest to build. Add Stripe for payments, and you add roughly 2 weeks of development and testing. Add a CRM sync, an email provider, an analytics pipeline, and a single sign-on provider, and you can add 6–8 weeks total. Integrations are not individually hard. They are cumulatively expensive because each one introduces edge cases, error states, and authentication flows that compound across the codebase.
Variable 2: Compliance and Security Requirements
Building a SaaS product that handles personally identifiable information, financial data, or health records adds a compliance layer that touches architecture, deployment, and documentation. In our ClearLedger fintech project, KYC/AML compliance added roughly 20% to the total project cost and 3 weeks to the timeline compared to a non-regulated build with the same feature set. The cost is not in the verification API integration itself. It is in the audit trails, the access control granularity, the data residency configuration, and the penetration testing. If your product operates in a regulated industry, plan for this from day one. Retrofitting compliance is three times more expensive than building it in from the start.
Variable 3: UI/UX Complexity
A dashboard with five views and standard components costs less to design than a product with custom data visualizations, drag-and-drop interactions, and real-time collaboration features. We price design separately from development, and the design scope is usually the first place we see budget expectations diverge from reality. Founders often underestimate how many screens a “simple” SaaS product actually requires when you account for empty states, error states, loading states, onboarding flows, settings, and user management. A product that seems like “10 screens” in a pitch deck is often 40+ screens by the time we map every state and flow.
Variable 4: Client Decision Velocity
This is the variable agencies rarely talk about publicly because it implicates the client. But it is the single biggest timeline multiplier we see. Projects where stakeholders consolidate feedback before design reviews and make decisions within 48 hours ship roughly 30% faster than projects with asynchronous, staggered input from multiple decision-makers. We have had projects where the engineering was on schedule and the design reviews added weeks because feedback trickled in across Slack, email, and three different stakeholders over seven days. The development team can only move as fast as the approval chain allows.
“The pricing question founders ask is ‘how much?’ The pricing question I wish they asked is ‘what is the smallest version that proves the model?’ In our project data, founders who came in with that framing spent an average of $40,000 less on their initial build — not because we cut corners, but because we cut features that did not prove the core hypothesis. Scope discipline is the most underrated cost-control tool in SaaS development.”
— Oleksandr Kostiuchenko, Marketing Manager at Phenomenon Studio, May 2026
We offer both pricing models, and we are opinionated about which one fits which situation. The wrong model choice causes more friction than a 10% rate difference ever will.
| Comparison Criteria | Fixed-Price | Time-and-Materials (T&M) |
| Best for | Scoped MVPs with locked feature sets and a defined deliverable by a specific date | Evolving product teams where the roadmap shifts based on user feedback |
| Budget predictability | High — total cost is agreed upfront | Moderate — monthly burn rate is predictable, total depends on duration |
| Scope flexibility | Low — changes require change orders and budget adjustments | High — priorities can shift sprint to sprint without renegotiation |
| Client involvement needed | Heavy upfront, lighter during build | Consistent throughout — weekly or biweekly reviews |
| Risk distribution | Agency carries scope risk; client carries change-order cost | Client carries scope and timeline risk; agency provides velocity |
| Typical engagement length | 2–5 months | 6+ months, often ongoing |
| Common in our projects | ~60% of new engagements start here | ~50% of fixed-price clients convert to T&M after MVP launch |
Data reflects Phenomenon Studio engagement models across 40+ projects, 2024–2026. Percentages are internal tracking, not industry averages.
Here is the pattern we see again and again: a founder comes to us with a fixed-price MVP scope. We build it in 10–16 weeks. It launches. Users provide feedback. The roadmap shifts. The founder realizes the product needs to evolve continuously, not in fixed-price chunks. That is when the conversation shifts to a time-and-materials retainer. About half of our fixed-price engagements convert to ongoing T&M relationships within three months of MVP launch. The fixed-price phase de-risks the initial build. The T&M phase provides the flexibility to respond to real user data.
If you are unsure which model fits your situation, ask yourself one question: Do I know exactly what needs to be built, or do I need to discover it through iteration? If the answer is the first, fixed-price works. If the answer is the second, start with T&M or plan for a fixed-price MVP that converts to T&M afterward. Lying to yourself about the certainty of your requirements is the fastest way to blow a budget on change orders.
I have watched founders make the same expensive mistakes enough times that I can list them from memory. These are not theoretical. They are patterns from real introductory calls where the engagement either did not happen or went sideways because of misaligned expectations.
Mistake 1: Shopping on price alone. I understand budget constraints. I have been on the founder side. But when you compare three agencies and pick the lowest bid without understanding what is excluded from that bid, you are not saving money. You are deferring cost to the second engagement when the first agency underdelivers and you need a rescue team. We have taken over multiple projects where the original agency quoted half our price and delivered a codebase that needed a full rewrite. The total cost to the client ended up higher than if they had hired us first. Get line-item scope breakdowns from every agency you evaluate. Compare what is included, not just the bottom-line number.
Mistake 2: Under-scoping the design phase. Founders who come in saying “the design is simple, we just need a clean dashboard” usually discover during wireframing that “simple” means 40 screens with edge cases, onboarding flows, and user management interfaces they had not considered. Design scope is the most underestimated line item in SaaS development. At Phenomenon Studio, we map every user flow and state before we write a line of code. That process surfaces scope that founders miss in their initial mental model. It adds time upfront and saves multiples of that time in development rework.
Mistake 3: Treating compliance as a post-launch checkbox. If your product handles payments, health data, or personally identifiable information, compliance is not something you bolt on after launch. It shapes your database schema, your API design, your deployment architecture, and your error handling. Retrofitting SOC 2 or HIPAA compliance into an existing codebase typically costs 2–3x what it would have cost to build it in from day one. We have seen this play out painfully in two projects we inherited. Build compliant from the start if your roadmap will eventually require it.
Mistake 4: Delaying the infrastructure conversation. Founders often assume hosting is a post-launch detail. It is not. Your infrastructure choices — serverless vs. containerized, multi-region vs. single-region, managed databases vs. self-hosted — affect your development architecture, your latency profile, and your monthly operating costs. We had a project where the client’s assumption of “just put it on AWS” collided with a data residency requirement that forced a specific region and a specific set of services that were not available in that region. The infrastructure replan added two weeks to the project. Have the hosting and infrastructure conversation during scoping, not after development starts.
Watch how our team approaches SaaS project scoping, pricing, and delivery — from introductory call to launch.
In early 2025, a fintech founder approached us with a clear problem statement: small accounting firms needed a transaction monitoring dashboard that could flag anomalies, verify client identities, and produce audit-ready reports — all while satisfying the compliance requirements of their banking partners. The founder had domain expertise and a waitlist of 30 firms. He did not have a product.
We scoped the engagement in two phases. Phase one was a fixed-price MVP: transaction ingestion, a rules engine for anomaly flagging, a client-facing dashboard, and KYC identity verification through Sumsub. Phase two was a time-and-materials retainer for iterative feature development based on user feedback from the initial 30 firms.
Phase one numbers: $135,000 fixed price. 16-week timeline. Team: one product designer, two full-stack developers (React and Python/Django), one DevOps engineer part-time, and a project manager. The compliance layer — identity verification, audit trails, role-based access, and data encryption at rest — accounted for roughly $27,000 of the total and 3 of the 16 weeks.
What went well: The founder consolidated feedback from his advisory board before every design review. Decisions happened within 48 hours. The project shipped on week 16, exactly on schedule. The 30 pilot firms onboarded within six weeks of launch. The transaction monitoring rules engine caught 94% of flagged anomalies in testing against historical data.
What we would do differently: We underestimated the integration complexity of the banking partner’s legacy API. Their documentation was incomplete, and their sandbox environment did not match production behavior. We burned an extra week in integration testing that should have been scoped as a separate workstream. Lesson learned: when a third-party integration is business-critical and the provider has a reputation for poor documentation, budget an integration buffer explicitly.
Phase two transition: After the MVP launched and the pilot firms provided feedback, the founder converted to a T&M retainer at a monthly rate with a dedicated team. The roadmap expanded to include automated report generation, a white-label client portal, and multi-currency support. The T&M arrangement let us prioritize features based on actual user requests rather than pre-launch assumptions.
Oleksandr Kostiuchenko summarized the engagement this way: “ClearLedger worked because the founder understood the difference between proving the model and scaling the product. Phase one proved it. Phase two scaled it. Mixing those two goals in one scope is how budgets spiral.”
If your product involves compliance, user data, or regulated workflows, we operate as a ui ux design agency that builds with those constraints from the first wireframe, not as an afterthought.
Technology Stack: What We Use and Why It Affects Cost
The technology stack does not just affect development speed. It affects your ability to hire, your hosting costs, your scalability ceiling, and your long-term maintenance burden. We are opinionated about stack choices because we have maintained enough legacy projects to know which decisions age well and which ones do not.
Front-end: React with Next.js is our default for SaaS products. It gives us server-side rendering for performance, a rich ecosystem for state management, and a hiring pool that makes ongoing maintenance feasible for our clients. For enterprise ERP interfaces with heavy data grids and form complexity, we sometimes use Angular. For projects where the front-end team is small and speed matters, Vue.js with Nuxt is a strong alternative that we have used on several projects.
Back-end: Node.js with Express or NestJS for projects where the front-end and back-end share TypeScript and the team benefits from a unified language. Python with Django or FastAPI for data-heavy applications, fintech, and anything involving machine learning pipelines. Laravel (PHP) for projects where rapid development, built-in authentication scaffolding, and a mature ecosystem matter more than raw throughput. Java Spring Boot for enterprise ERP and manufacturing systems where long-term stability and strict typing are non-negotiable.
Database: PostgreSQL for almost everything. It handles relational data, JSON columns, full-text search, and geospatial queries. We use MongoDB only when the data model is genuinely document-oriented and the schema is expected to change frequently. We avoid database proliferation — one well-chosen database beats two that overlap.
Infrastructure: AWS for most projects, with Vercel for front-end hosting on Next.js projects. We build with containerization (Docker) and orchestration (Kubernetes for larger deployments, ECS for smaller ones) so the application is portable across cloud providers. For clients with data residency requirements, we configure single-region deployments with backup replication within the required jurisdiction.
The stack conversation should happen during scoping because it affects your long-term cost of ownership, not just the initial build budget. A React/Node.js stack is easier to hire for than a niche framework. A managed database service costs more per month than a self-hosted instance but eliminates a class of operational risk. These tradeoffs are not obvious to first-time founders, and part of our job is making them explicit.
How much does it cost to build a SaaS application with Phenomenon Studio?
Based on 40+ projects we have delivered, SaaS development with Phenomenon Studio ranges from $45,000 for a focused MVP to $350,000+ for a full-featured platform with compliance requirements. The median project in 2025 landed at $125,000. What drives the range is scope depth: a single-purpose tool with basic auth and a dashboard sits at the low end. A multi-tenant platform with role-based access, payment infrastructure, third-party integrations, and HIPAA or SOC 2 compliance sits at the high end. We quote fixed-price for scoped MVPs and time-and-materials for ongoing product teams. Oleksandr Kostiuchenko says the question he wishes more founders asked is not “how much?” but “what is the smallest version that proves the model?” That framing saves an average of $40,000 in unnecessary build from our project data.
How long does it take to develop a SaaS product from scratch?
A focused SaaS MVP takes 10 to 16 weeks with our dedicated team. A production-grade platform with compliance, integrations, and polished UX takes 5 to 9 months. Our fastest launch was a fintech dashboard MVP that shipped in 9 weeks because the founder had crisp requirements and made fast decisions during design reviews. The slowest was an ERP module that took 11 months because the client’s internal stakeholder alignment added weeks to every feedback cycle. The timeline variable we cannot control is client-side decision velocity. Projects where stakeholders consolidate feedback before reviews ship roughly 30% faster than projects with asynchronous, staggered input.
How do you price SaaS product development — fixed price or hourly?
We offer both models, but we recommend them for different situations. Fixed-price works for scoped MVPs where the feature set is locked and the goal is a defined deliverable by a specific date. Time-and-materials works for product teams where the roadmap evolves based on user feedback and the engagement is ongoing. In 2025, roughly 60% of our new engagements started as fixed-price MVPs, and about half of those converted to time-and-materials retainer relationships after the MVP shipped. The fixed-price phase proves the concept. The retainer phase scales it.
How do I start a SaaS project with your agency?
The process starts with a free consultation call where we map your idea to scope, timeline, and budget. You do not need a complete spec. We work from napkin sketches, competitor references, and written problem statements. After the call, we deliver a proposal with a phase-one scope, a fixed price or rate card, a team composition, and a week-by-week timeline. Projects typically kick off within two weeks of signed agreements. We also sign NDAs before any detailed discussion if that is a concern.
Can you build a fintech app with KYC/AML compliance?
Yes. We have built fintech applications that integrate KYC/AML verification through providers like Sumsub, Onfido, and ComplyAdvantage. In our ClearLedger project, we built a transaction monitoring dashboard with automated flagging rules, identity verification workflows, and audit trails that satisfied the client’s banking partner requirements. The compliance layer added roughly 20% to the total project cost and 3 additional weeks to the timeline compared to a non-regulated SaaS build. We plan for this upfront in the scope, not as a discovery-phase surprise.
What is the average cost of an ERP system for a small business?
Custom ERP development for a small business typically falls between $60,000 and $180,000 depending on the number of modules, integrations, and whether it is cloud-based or on-premise. Off-the-shelf ERP like SAP Business One starts around $3,000 per user per year but often requires customization that adds $20,000 to $80,000 in implementation costs. We have found that businesses with unique workflows, manufacturing processes, or compliance requirements often find custom ERP more cost-effective over a three-year horizon because they avoid ongoing licensing costs and forced workarounds. The break-even point versus off-the-shelf solutions usually lands around the 18-month mark.
Do you offer SaaS design and development as a package?
Yes, and this is how most of our engagements work. We combine UI/UX design, front-end development, back-end development, and DevOps into a single team with a single point of contact. Founders who bundle design and development with us avoid the integration friction that happens when design and engineering live in separate agencies. In our internal project data, bundled projects ship 25% faster than projects where design and development are sourced separately, simply because the feedback loops are shorter and the accountability is consolidated.
Do you sign NDAs before project discussions?
Yes, we sign NDAs as a standard practice before any detailed project discussion. Most founders request this, and we have a template ready to go. If you have your own NDA, we review and sign it within one business day. We take idea confidentiality seriously, and we are comfortable putting that in writing before you share anything sensitive.
How much does custom ERP software development cost?
Custom ERP development ranges from $60,000 for a single-module system to $250,000+ for a full-suite implementation with manufacturing, inventory, finance, and CRM modules. The cost drivers are the number of modules, the number of third-party integrations (accounting software, payment gateways, supplier systems), and whether the deployment is cloud-based or on-premise. We scope ERP projects module by module and recommend starting with the highest-impact module rather than building everything at once.
Can you build cloud-based ERP or on-premise solutions?
We build both. Cloud-based ERP on AWS or Azure is our default recommendation because it reduces infrastructure management overhead and scales with usage. We build on-premise ERP when the client has regulatory requirements, data sovereignty constraints, or existing server infrastructure they want to leverage. On-premise deployments typically add 15–25% to the project cost due to environment configuration, VPN setup, and the additional testing required for varied hardware environments.
Do you provide ERP consulting before development?
Yes. We offer a discovery and consulting phase before development begins. This typically runs 2–4 weeks and includes stakeholder interviews, workflow mapping, technology assessment, and a build-vs-buy analysis. The output is a detailed scope document with module prioritization, integration requirements, and a phased budget and timeline. This phase is billed separately or included in the full project scope depending on the engagement structure.
How do I hire a product design and development agency?
Start with a shortlist of agencies that have built products in your industry or with similar technical requirements. Review their case studies — not just the visuals, but the problem statements, the constraints, and the measurable outcomes. On introductory calls, ask about team composition (who actually does the work?), engagement models, and how they handle scope changes. Ask for references from founders whose projects shipped at least six months ago — recent projects have not aged enough to reveal maintenance issues. At Phenomenon Studio, we offer a free consultation call where we walk through your idea and provide a preliminary scope and budget range before any commitment. No pressure, no obligation.
Do you work with startups or only enterprise clients?
We work with both. Our startup clients typically come to us with an MVP scope and a budget aligned with pre-seed or seed funding. Our enterprise clients come with more complex requirements, compliance constraints, and longer procurement cycles. The team composition and process adapt to the client size, but the quality standard does not change. We have built products for solo founders and for organizations with 5,000+ employees.
Do you offer ongoing support after product launch?
Yes. Every project includes a warranty period after launch where we fix bugs and address issues at no additional cost. After the warranty period, we offer ongoing support and maintenance retainer packages that include bug fixes, dependency updates, performance monitoring, and feature enhancements. Most of our clients stay on some form of retainer after launch because software requires continuous maintenance, not just initial development.
I want to close with something that goes beyond numbers. After enough introductory calls, you start to notice patterns in which engagements succeed and which ones struggle. The budget number matters less than the alignment behind it.
Founders who focus on scope discipline have an easier time with budget. When a founder comes in saying “here is the problem, here is the user, here is the smallest thing that solves it,” the scoping conversation is productive and the budget lands in a comfortable range. When a founder comes in with a feature list copied from a competitor’s marketing page and no prioritization framework, the scope balloons and the budget follows. The difference is not the complexity of the product. It is the clarity of the founder’s thinking about what matters and what can wait.
The cheapest quote usually costs the most. I said this in the mistakes section, but it bears repeating because it is the most expensive lesson founders learn. When you compare three agency quotes and one is dramatically lower, ask what is excluded. Ask about the team composition. Ask about the engagement model. Ask about post-launch support. The difference is almost never efficiency. It is almost always scope exclusion or corner-cutting that surfaces after launch.
Bundled design and development eliminates the most expensive friction in software projects. When design and engineering live in the same agency, the designer knows what is technically feasible before they design it. The developer understands the design intent because they were in the review. The project manager tracks one timeline, not two that need to be synchronized. It costs more on paper than hiring a design-only agency and a dev-only agency separately, but it costs less in practice because the integration tax disappears. We have the data to prove it: bundled projects ship 25% faster.
If you are evaluating agencies, start with a conversation. Not a proposal, not a pitch deck — a conversation about your product, your users, and your constraints. The right agency will ask better questions than you expect and tell you things you did not want to hear. That is how you know they are being honest.
