Applications built to still make sense in two years
Full stack web application development covers everything from the database schema to the interface: authentication, permissions, business logic, integrations and deployment. It is the right call when off the shelf software forces your process into a shape it does not fit, or when the workaround has become a spreadsheet nobody can audit.
Who this is for
You probably need this if…
If none of these sound familiar, you may not need us yet, and we would rather say so now.
A critical business process runs on a spreadsheet that one person understands.
You are paying per seat for software you use ten percent of.
Customers keep asking for a portal and you keep sending PDFs.
The internal tool a contractor built three years ago cannot be deployed any more.
Two teams maintain two versions of the same data because no system holds both.
Scope
What's included in full stack web application development
Every item below is a deliverable with an owner and a date, not a capability we happen to have.
- 01
Architecture and data model
Schema, access model and service boundaries decided and written down before anyone opens an editor.
- 02
Authentication and permissions
Real role based access, not a boolean called isAdmin. Multi tenancy and SSO where the business needs them.
- 03
Application
Server rendered, typed end to end, tested where tests earn their keep, and fast on the devices people actually use.
- 04
Integrations
The APIs, webhooks and data feeds the application depends on, with retries and error reporting rather than optimism.
- 05
Observability
Structured logging, error tracking and performance monitoring, so a production problem is diagnosable instead of mysterious.
- 06
Documentation and handover
Architecture notes, a deploy runbook and an onboarding path, so a new developer is productive in days.
Process
How a full stack applications project runs
6 stages over 10 to 16 weeks. You get a written plan before stage one, and a named owner on our side throughout.
Discovery
Weeks 1 to 2We map the real process, including the parts people work around. Those workarounds are requirements in disguise.
Architecture
Week 2Data model, access model and integration contracts, agreed in writing before the build.
Build in increments
Weeks 3 to 10Shipped to staging every week, reviewed against real data rather than placeholder records.
Hardening
Week 11Load testing, security review, accessibility pass and the error paths nobody enjoys writing.
Migration and launch
Week 12Data brought over from whatever it lives in now, then a staged cutover with a rollback plan.
Stabilisation
Weeks 12 to 16Thirty days of monitoring and fixes while real usage finds the edges.
Commercials
Timeline and cost
Full Stack Web Application Development starts at $30,000 and typically takes 10 to 16 weeks. Fixed price confirmed after discovery. Support retainers from $2,500/month.
That figure is a starting point, not an estimate we revise upward later. The first week of every engagement is a scoping week that ends with a fixed fee and a fixed date. If the scope turns out to be smaller than we assumed, the fee goes down.
We do not bill by the hour for project work. Hourly billing pays us to be slow, and it makes your budget a function of our efficiency rather than of your requirements.
FAQ
full stack web application development questions
Direct answers. If yours is not here, ask us and we will add it.
When should I build custom software instead of buying it?
Build when the process is genuinely your competitive advantage, when off the shelf tools force a workflow that costs real money to work around, or when per seat licensing has outgrown a one time build. Buy when the problem is common and a mature product already solves it. We will tell you when the answer is buy.
How much does a custom web application cost?
Custom applications start at $30,000 and commonly land between $45,000 and $120,000 depending on user roles, integrations and data volume. The discovery phase produces a fixed price before the build begins, and that price does not move unless the scope does.
Can you work with our existing codebase?
Yes. We take on inherited applications regularly, and the first deliverable is an honest assessment: what is salvageable, what needs replacing and what the ongoing cost of each option looks like. Sometimes the answer is that a rewrite is cheaper than the maintenance, and sometimes it very much is not.
What happens if we want to take it in house?
That is a planned outcome rather than a problem. Code lives in your repository from day one, infrastructure runs under your accounts, and the documentation is written for a developer who has never spoken to us. We will also run paid onboarding sessions for whoever takes it over.
