Custom Software Development Services
Purpose-built software on modern stacks for teams that outgrew templates and off-the-shelf tools.
Who this is for
If any of this sounds like you, we should talk.
You tried no-code and hit the ceiling
Webflow, Bubble, or Zapier got you to v0.1. Now you need real business logic, custom integrations, and a codebase you can scale. Time for a developer.
You have a feature only a custom app can solve
Your workflow is unique. Off-the-shelf software does not fit. You need something purpose-built for how you actually work.
You are raising and investors want to see production code
Demo works. Unit economics work. Now you need a codebase that scales, is secure by default, and does not make the first engineer run screaming.
You have existing users and the app is slowing you down
V1 was a hack. It worked. Now it is fighting you. You need someone to stabilize the code, add the features your customers are asking for, and keep shipping.
What changes for you
Outcomes you can point to, not features you can ignore.
- A custom app that solves your exact problem, not a templated compromise.
- Production-grade code on modern stacks (React, Next.js, TypeScript, Supabase, Stripe).
- A codebase you own outright. No licensing, no lock-in, no surprises.
- An app that survives 10x growth without a complete rewrite.
- Clean handoff to your own team or a care plan to keep us on retainer.
What is included
Scope, organized by phase.
Scope and Design (Phase 1 of 5)
Phase 1
Scope and Design
What we lock down in this phase before moving on.
- Product scope workshop to nail what actually needs building
- Wireframes and user flows for every feature in v1
- Tech stack recommendation (React, Next.js, backend choice, database)
- Fixed timeline and milestone breakdown
How an engagement works
From hello to handoff, step by step.
You book a discovery call
We talk through what you are building, why, and who is paying for it. We ask hard questions about scope and timeline.
You get a proposal within 48 hours
Fixed price, fixed timeline, fixed scope. Everything is written down. No surprises at sprint eight.
We build in 2-week sprints
Every sprint ends with a real feature on staging. You can click through it, use it, give feedback.
You get weekly demos and updates
Every Friday, a 15-minute demo of what shipped that week. Async written update. No vague status reports.
We launch and hand off
Deployed to production, docs written, repo handed over, 30 days of support. You decide what comes next.

Case study
SCRAPD Marketplace
Live, revenue-generating marketplace shipped from Figma to live customers in under 10 weeks. Sellers onboarding weekly. Real transactions flowing through Stripe Connect.
A upcycled fashion marketplace founder had a Figma file and zero technical infrastructure. They needed a real platform where sellers could list inventory, customers could browse and buy, and they could take a cut of every transaction.
We built a multi-vendor marketplace on Next.js and Supabase with Stripe Connect for seller payouts, role-based access (seller, buyer, admin), and an admin dashboard for marketplace operations.
Why us
What you get with WitsCode that you don't get elsewhere.
We ship scalable production code, not startup theater
Error handling, logging, monitoring, database indexing, security. All the boring parts that separate a demo from something 1000 users can actually use.
Modern stack by default, boring by choice
React, Next.js, TypeScript, Supabase, Vercel. Proven patterns that let you hire senior engineers and ship fast. No framework roulette, no experimental stacks.
We respect your codebase and your roadmap
You own the code. You own the repo. You decide what happens next. We can hand off to your team, stay in a care plan, or disappear. Your call.
WitsCode rebuilt our Shopify store so it finally converts the traffic we were already getting. They understand speed and storytelling in equal measure, and the store has been a real growth lever since launch.

Frequently asked
Questions before you reach out.
Custom software development is the design and engineering of software built specifically for one business, its workflows, and its data, instead of adapting an off-the-shelf product, giving you exact-fit features, full ownership of the code, and a system that changes when your business changes. That is what we build: internal tools, customer portals, marketplaces, and the systems in between.
Custom software cost depends on scope, integrations, and timeline, so we do not publish flat rates; instead you get a fixed, written proposal after a short scoping conversation, with the price and milestones locked before any code is written so there are no surprises at sprint eight. Tell us what you are building at /start and you get a scoped estimate within 48 hours.
Buy off the shelf when a proven product covers 80 percent of your workflow at a price that scales; build custom when your process is your competitive edge, when subscription costs compound past the cost of owning, or when no product fits how you actually operate. We will tell you if buying is the right call. A build you did not need is a bad reference for us.
Most custom software projects ship a first production version in 8 to 16 weeks, depending on the number of user roles, integrations, and workflows in scope, and you get a firm timeline with milestones at the end of discovery rather than an open-ended estimate. We build in 2-week sprints. Every sprint ends with something you can click on staging.
You own everything: full IP transfer on final payment, including the repository, infrastructure credentials, documentation, and runbooks, with a structured handover to your own engineers or an ongoing care plan if you want us to keep shipping, and no licensing, royalties, or lock-in of any kind. Handover includes docs, a walkthrough, and 30 days of bug fixes on us.
We build on React, Next.js, and TypeScript on the frontend, with Supabase (Postgres plus Edge Functions), Node.js, or Python on the backend, choosing boring, proven technology that senior engineers already know so you can hire for it, extend it, and run it for years. No framework roulette. The stack recommendation is part of discovery and we justify every choice in writing.
Yes, we audit the existing code first, stabilize what is broken, and build on what works, because a full rewrite is rarely the right answer; most inherited projects need indexing, error handling, tests on critical flows, and a cleanup of the riskiest paths, not a restart. We sign a standard mutual NDA before we look at anything.
