A recent project · Streetlight Media

Custom production workspace for attendance, tasks, and client reports.

Replaced multiple disconnected tools with a bespoke team workspace, delivered and operational on a strict 30-day timeline.

  1. 01
    Brief

    Streetlight Media struggled with disjointed spreadsheets and manual messaging for staff check-in, creative task tracking, and client milestone approvals.

  2. 02
    Approach

    We built a bespoke web application featuring GPS check-in, real-time kanban task boards, role-based client review portals, and automated progress reports.

  3. 03
    Handover

    Delivered in the client's private repository with full documentation, reducing administrative coordination time by over 18 hours per week.

Get A Free Quote
01How much does it cost to build a custom web application in 2026?

The cost of custom web application development varies according to feature complexity and scale. A streamlined MVP (Minimum Viable Product) or internal portal typically ranges between $1,500 and $3,500. A comprehensive commercial SaaS platform with multi-tenant workspaces, subscription billing, and complex dashboards ranges from $3,500 to $8,000+. For ongoing product engineering, our dedicated product squads run from $1,800 per month. We provide a detailed scope document with fixed milestone pricing before any work begins.

02How long does it take to build a custom web application from start to launch?

A focused MVP typically takes between 4 and 6 weeks to develop and launch. A full-featured custom SaaS platform or complex internal ERP system takes between 8 and 12 weeks. Because we work in agile 1-to-2 week sprints, you see and test clickable working software in your staging environment every single week rather than waiting months for a final release.

03Who owns the intellectual property (IP) and source code?

You do. 100%. All custom code, database schemas, UI design assets, and architectural documentation are created directly in your private GitHub or GitLab repository. Upon milestone payments, all intellectual property rights belong exclusively to your company. We never charge ongoing licensing or royalty fees.

04Which technology stack do you use for web application development?

We select modern, proven, enterprise-grade technologies based on your product's specific requirements. For the frontend, we primarily use React, Next.js (App Router), TypeScript, and Tailwind CSS. For the backend, we use Node.js/Express, Python/FastAPI, or Laravel (PHP 8.3). For databases, we employ PostgreSQL or MySQL with Redis caching, and host on AWS, Google Cloud, or DigitalOcean with Docker containerization.

05Can our custom web application integrate with our existing software and tools?

Yes. Custom software is built specifically to bridge gaps between existing business tools. We can integrate your web app with any third-party system that provides an API—including HubSpot, Salesforce, QuickBooks, Stripe, PayPal, Google Workspace, Slack, Twilio, and proprietary legacy databases.

06How do you handle user authentication and data security?

Security is engineered into our architecture from the foundation. We implement industry-standard authentication (OAuth 2.0, JWT, NextAuth, or Auth0) with optional multi-factor authentication (MFA). We configure strict Role-Based Access Control (RBAC) to restrict user permissions, sanitize all inputs against SQL injection and XSS vulnerabilities, encrypt sensitive data at rest, and adhere to OWASP Top 10 security standards.

07What is an MVP and why should we start with one?

An MVP (Minimum Viable Product) focuses on building the core 20% of features that deliver 80% of the value to your users. Starting with an MVP allows you to launch quickly (within 30–45 days), validate your software in the market with real customers, collect authentic user feedback, and iterate intelligently without overspending on features users might not need.

08Can you build custom subscription billing and recurring payments?

Yes. We frequently integrate Stripe Billing and Customer Portals into SaaS web applications. We handle monthly/annual recurring subscription plans, tiered pricing, usage-based metering, free trials, coupon codes, automatic invoice PDF generation, and webhook event handling for failed payments.

09How do you ensure the web application can scale as our user base grows?

We design stateless application architectures with separation of concerns: frontend assets are served via global edge CDNs; backend APIs run on scalable containerized cloud instances; and databases utilize connection pooling, indexing, and Redis in-memory caching. This architecture easily scales from your first 100 users to hundreds of thousands of concurrent sessions.

10What happens after the web application is launched? Do you offer support?

Every custom build includes 30 days of comprehensive post-launch warranty support to resolve any edge-case bugs and ensure smooth operational handover. After launch, we offer dedicated maintenance care plans and retainer squads for continuous feature expansion, cloud DevOps management, and security updates.
