Custom web apps

When a website isn't enough, we build the system that runs the business.

CrecyStudio builds custom software for businesses that have outgrown spreadsheets, disconnected tools, or off-the-shelf limits. Product strategy, architecture, implementation, launch, and handoff are handled as one system.

Pour qui

Best for teams that need senior product and engineering ownership from scope through launch.

+
You have a process that lives across spreadsheets, Notion, and a dozen browser tabs.
+
You've validated a software idea and need someone to actually build it.
+
You need a tool your customers will log into, not just a marketing site.
+
Your team spends more time managing workarounds than serving customers.
+
You're at a growth-stage company and need senior product and engineering ownership from scope through launch.

Idéal pour

Best fit for…

Founders shipping their first software product
Operators replacing manual processes with a real system
Agencies needing white-label internal tools
Growth-stage teams that need a senior architect with product judgment — not a ticket queue

Pas le bon premier pas

Probably not the right call if…

-
An off-the-shelf tool already does it — we don't rebuild what HubSpot, Stripe, or Linear already build
-
You need a $500 patch, not a new system
-
You want to own zero code or documentation after delivery

Problèmes que nous résolvons

Four signs the business has outgrown off-the-shelf software.

Your workflow spans tools that were never designed to work together.

Off-the-shelf software forces workarounds instead of matching how the business actually runs.

An existing app is incomplete, brittle, or difficult to extend.

Customers or staff need one reliable system instead of five disconnected tools.

Processus

How a custom app gets built.

Every project starts with a call, not a quote. We scope before we price so there are no surprises mid-build.

01 — Discovery

Define the system

Scope, user roles, data model, integration needs. Optional paid discovery sprint for complex scopes where figuring out what to build is itself the hard problem.

02 — Build

Milestone-based delivery

Build in your shared workspace with full visibility. You see every milestone as it ships. Scope changes go through a change-order process — no surprises.

03 — Launch

Handoff and ownership

Deployed on your accounts. Documented so any developer can understand the system. Optional Care Pro retainer if you want ongoing iteration.

Tarifs

Priced to the scope, not to a template.

All Web Apps projects start with a 30-minute strategy call. Prices are ranges — final scope determines cost. Discovery sprint is optional for clear, well-defined scopes.

Discovery sprint

$2,500–$5,000

Paid scoping engagement before MVP commit. Results in a scope document, milestone plan, and budget bands.

Optional for clear scopes

MVP

$18,000–$35,000

First working version of a focused product. Validated scope, core workflows, one user role, deployment.

Most common starting point

Standard build

$35,000–$75,000

Full product with multiple user roles, admin panel, integrations, payments, documented handoff.

Scoped to your project

Complex scope

$75,000+

Multi-tenant SaaS, complex data models, AI integration, white-label systems, or enterprise-grade architecture. Typically a 3–6 month engagement. Discovery sprint required. You own all code, IP, and documentation from day one — nothing held back.

FAQ

Custom web app FAQ

Do I have to start with a discovery sprint?

No — if your scope is well-defined, we can move straight to an MVP proposal. Discovery is for cases where figuring out what to build is itself the hard problem.

What stack do you build on?

Next.js + Supabase by default: TypeScript, React, PostgreSQL, auth, file storage, and real-time built in. We adapt for specific requirements.

What makes the CrecyStudio process different?

Strategy, architecture, implementation, and launch stay connected through one delivery process, with milestone-based payments, documented handoff, and a shared workspace throughout.

How do I know this won't go over budget or timeline?

Scope is locked before a dollar is committed. If a change order is needed, it gets priced, approved, and documented before any new work starts — scope creep doesn't happen silently here. Discovery sprints exist specifically to prevent budget surprises on complex projects.

Do I need a technical background to work with you?

No. We translate business requirements into working software — you describe what the system needs to do, we handle the architecture. Most of our clients aren't developers. The workspace keeps you in the loop without requiring you to read code.

What do I actually own when the project is done?

Everything — the source code, the database, the hosting accounts, the domain. Full IP transfer once the final invoice is paid. We don't hold code hostage or retain any license to the work. The handoff documentation means any developer can understand and extend the system.

What happens after launch if I need changes?

You own the code and can hire anyone to maintain it. We offer an optional Care Pro retainer for clients who want ongoing iteration from us. Most clients start without it and add it after they've validated traction.

What happens if this engagement falls apart mid-project?

Your code lives in a repository you control from day one. Every milestone includes documentation, and the handoff plan is defined before work starts so another qualified developer can continue the system if needed.

Who is responsible for delivery?

CrecyStudio is founder-led, so the person responsible for scope and architecture stays directly involved through implementation and launch. You have a clear owner for the outcome throughout the engagement.

What's the process when scope changes mid-project?

Any change to scope goes through a written change order — priced, documented, and approved before a line of new code is written. Nothing is added silently and nothing inflates the bill without your sign-off. This is built into the contract from the start, not handled informally.

The discovery call has no commitment. If a different approach is better for the project, we'll say so.
