Custom Software & SaaS Development Built to Scale
Senior-level custom software development for founders, product teams and organizations that run on their software. We plan, build, launch and maintain SaaS platforms, internal tools, member portals, dashboards and mobile apps, and you work directly with the people who write the code.
- One partner from discovery and architecture through launch and ongoing support
- SaaS foundations from the first release: sign-in, roles and permissions, organization accounts and billing-ready data
- Clean, typed, tested code your next developer can read and extend
- Security and performance checked before every release
- A fixed price for each phase, and the code is yours on final payment
- Direct contact with the people writing and shipping your software
What We Build
- SaaS applications: subscription-based platforms and scalable web application development
- Member portals: account activation, a dashboard of each member's status, online payments, secure document uploads and the staff tools behind them
- Multi-tenant systems: we can build separate workspaces for each organization, with user authentication and role management
- Customer-facing dashboards with analytics, reporting, and real-time visibility
- Admin panels for operations: user management, content workflows, and support tooling
- Online payments and billing: Stripe checkout by card or bank transfer, webhooks that record each payment, and billing logic for recurring or prorated charges
- Internal tools that automate workflows, reduce manual work, and improve data quality
- Companion marketing websites: conversion-focused landing pages and CMS-driven content
- Mobile app development for iOS & Android using React Native / Expo
- API & backend engineering: REST APIs, scheduled jobs and third-party integrations built for long-term maintainability
Why Senior-Level Custom Software Development Matters
Software is a business asset. The gap between a prototype and software you can run a business on is architecture, careful execution and discipline after launch. We build for production from the first sprint: access rules that hold, records you can audit, and tests that run on every change. You ship quickly now without paying for a rewrite later.
Production-Ready SaaS Foundations
We design for real-world SaaS needs: authentication & authorization, organization accounts, billing-ready data models, auditability, and secure API boundaries. Access rules are checked on the server and in the database, not only in the interface, so a hidden button is never the only lock.
Maintainable Systems, Not Fragile Code
Typed code, predictable patterns and automated tests keep your codebase readable and safe to change. Every change goes through a pull request and automated checks before it ships, and tests run against realistic data.
Business-First Engineering
We align technical decisions with product goals: reduce risk, validate assumptions, ship an MVP, then iterate into a durable platform.
Faster Iteration After Launch
A well-built platform accelerates future work. You'll be able to add features, onboard users, and improve UX without constant rewrites.
Security From the First Commit
Least-privilege roles, row-level security in the database and validated input are part of the build, not an add-on. Payments go through Stripe Checkout, so card details never touch your servers.
Tools Your Staff Can Run Themselves
Admin panels, imports and reports let your team handle day-to-day work without calling a developer. On the benefits fund member portal we built, staff manage members, payments, document uploads and email blasts on their own.
The Full-Stack Tools We Use
If you're looking to hire a software engineer or a Next.js development agency, the stack matters. We use proven, widely supported tools, so your app is quick to build, easy to hire for later and never locked to us. Most of it runs in the projects further down this page.

SaaS-Focused Development Process
Most custom apps take 3-6 months from kickoff to launch. We split the work into phases, each with fixed hours and a fixed price, and you review every milestone on a staging site before we move on. Testing runs through every phase, not just the end.
Consultation & Proposal
Before kickoffA free consultation, usually about 30 minutes and up to an hour for larger projects. Then a written proposal with the phases, hours and price for each. Once you approve it, we start within 3-5 business days.
Discovery & Requirements
1-2 weeksClarify goals, users, constraints and what success looks like. Map each user role and core workflow, list the risks, and agree on what the first release must include.
Architecture & Technical Planning
1-2 weeksDesign the data model, organization boundaries, API contracts, sign-in and permissions, and the deployment setup, with security and growth in mind.
Core Build
6-10 weeksBuild the core workflows, dashboards and admin panel essentials on a production-ready foundation. Each milestone goes to a staging site, and you have 5 business days to review it and ask for revisions.
Features, Integrations & Iteration
3-8 weeksAdd payments, email, imports and third-party integrations, then refine the UX with feedback from real users, in small, reviewed increments.
Testing, Launch & Handover
1-2 weeksFinal testing of edge cases, permissions and performance. Set up CI/CD, monitoring and error tracking, then go live. Hosting, database and email are billed to you directly by the providers.
Free Fixes & Ongoing Support
After launchYou get free bug fixes for at least one month after launch, longer for larger projects (2-3 months on a member portal with online payments, to cover a full billing cycle). After that, support is optional: hourly as needed, or a monthly plan from $375 for 5 hours.
Pricing Custom Software
Software is quoted per project, once we understand the users, the data and the integrations involved. The estimator gives you a starting range in a few clicks, and the free consultation turns it into a fixed-price proposal broken into phases.

Frequently Asked Questions
Got questions? We've got answers. Find the most common questions about this service below.
Do you build SaaS products end-to-end?
Yes. We handle SaaS application development from discovery and architecture through implementation, deployment, and ongoing iteration. That includes authentication, role management, dashboards, admin panels, and integrations, and we can build multi-tenancy (separate workspaces for each organization) when your product needs it.
How much does custom software development cost?
Most custom app projects fall in our Custom App Development tier, $18,000 - $50,000, and take 3-6 months. Where yours lands depends on how many user roles and workflows it has, payments and other integrations, moving data from an old system, real-time features, and whether you need a mobile app too. Every proposal breaks the work into phases with fixed hours and a fixed price, so you know the cost before work starts. You pay in four equal 25% milestones, usually the first at kickoff and the last before launch.
Who owns the code when the project is done?
You do. Once the final payment is made, the code, designs, database structure and other deliverables are yours. Your domain is registered in your name, and if a project starts on our hosting or code accounts for convenience, we move it to yours whenever you ask. We may show non-confidential parts of the work in our portfolio.
Can you work with a non-technical founder or product manager?
Yes. We translate requirements into technical plans, propose sensible tradeoffs, and keep communication straightforward. You'll always know what's being built, why, and what's next. You'll review each milestone on a staging site before we move on.
What's your typical approach to MVP development?
We define the smallest set of workflows that prove value, then build an MVP with a scalable foundation. The goal is to launch quickly without creating a codebase that needs to be rewritten after traction.
Can you take over a project that's already started?
Yes. We start with a code and UX audit: what's solid, what's risky and what to fix first. Then we finish features, fix bugs or rebuild the weak parts, in phases with fixed hours and a fixed price. Work on an existing app usually falls under our Update Existing Site/App tier, $1,000 - $10,000; a larger rebuild is quoted as a custom app. Once you approve the plan, we start within 3-5 business days.
Are hosting and maintenance included?
Hosting isn't part of the build price. Hosting, database and email are billed to you directly by the providers: for a web app with a database and email, usually about $100-$250 a month. We handle the setup as part of the project. You also get free bug fixes for at least one month after launch, longer for larger projects (2-3 months on a member portal with online payments, to cover a full billing cycle). After that, support is optional: hourly as needed, or a monthly plan from $375 for 5 hours.
Do you build mobile apps too?
Yes. We build iOS and Android apps with React Native and Expo, often as companion apps that connect to an existing SaaS platform or internal API.
How do you handle security and access control?
We design authentication & authorization intentionally: roles/permissions, least-privilege access, secure API boundaries, and careful handling of sensitive data. We also prioritize dependency hygiene and secure deployment practices.
Can you join an existing team as a contractor or augment staff?
Yes. If you need to hire a software engineer for a specific initiative, we can integrate into your workflow, ship features, and improve code quality while keeping delivery predictable.
