- Which parts do we build, and which do we buy?
Where it stops
Builds the interface on an API your team already runs.
Web App Development
Builds the whole app: interface, server, data and release.
Not included
- Security or uptime beyond the agreed criteria
- User, revenue or growth figures
A working web app, and what it takes to run it
What you hold at the end, from the written scope to the release.
-
Technical scope and acceptance criteria
The first release, its architecture, and the test that says each feature is done.
-
The web app itself
Every screen, role and workflow in scope — frontend, backend and database — deployed.
-
Connected services and moved data
Payments, email, sign-in and your own systems wired in, and existing records carried over.
-
Test evidence and a responsibility map
Test results, release notes, a runbook and who owns what after release.
You receive
- Source code in your repository
- The app on your cloud account
- Docs, runbook and a walkthrough
Built one working slice at a time.
Custom web application development goes wrong where ownership is vague. So before the first commit we agree who owns what, what each step needs from you, and when it counts as done.
-
Architecture and foundation
Stack, data model and API contracts agreed; environments, sign-in and the deployment pipeline set up. Needs Approved designs or flows, and a cloud account or a decision on one.
Done when A test user signs in to a staging app, and every change is built and tested automatically.
-
Workflow by workflow
Each workflow built end to end — screens, API, data and permissions — and shown working before the next one starts. Needs A product owner who reviews each slice within the agreed window.
Done when The workflow passes its acceptance criteria with realistic data, for every role that uses it.
-
Integrations and data
Payments, email and your own systems connected; existing records moved in by script, rehearsed on a copy first. Needs Sandbox keys and admin access for each service, and an export of the data to move.
Done when Every external call is logged, a failed one is retried or flagged, and record counts match the source.
-
Quality and release
Security, accessibility and speed checked; monitoring and backups in place; then a staged release. Needs Test users for each role, and one person who approves go-live.
Done when The agreed test cases pass, alerts reach a named owner, and a rollback has been rehearsed.
-
Handoff
Code, documentation, the runbook and every access handed over to your engineers. Needs Your repository and cloud accounts, or ones we transfer to you.
Done when Your team deploys a change and restores a backup without us.

A web platform we designed and then built
One team took Payyro from a UX audit to a first release, then to a redesign it is now building, so every design decision was made knowing our own developers would build it.

Payyro
Designed and then built a four-role crowdfunding platform — people asking for help, donors, vendors and a Super Admin: a first release on Webflow and Wized, and a second version in Next.js and Supabase now in development.
- 400+ Unique screens
- 5 Experts on the team
When a custom web app is worth building
It pays off when the product is the way your business works, not a side tool. Four signs it is the right step now.
-
A real process runs on spreadsheets
Orders, requests or approvals pass between people by hand, and mistakes are creeping in.
-
Off-the-shelf tools no longer fit
Workarounds, plug-ins and per-seat fees now cost more than they save.
-
Several sides meet in one product
Customers, vendors and your own staff each need their own view, rules and data.
-
The first version has hit its limits
A no-code build or prototype proved demand and now slows every change.
A different starting point
- The product isn't designed yet — roles, flows and screens are still open Web App Design
- Your team runs the backend and needs only the interface layer Frontend Development
- You need the smallest version that tests demand first MVP Development
- It is not yet clear what to build, or whether to build at all Product Discovery
Let's scope the first release of your web app
Tell us what the product has to do and who signs in to it. We will come back with a first-release scope and a realistic next step.
Scope, access and who does what
The first release, the stack, the acceptance criteria and the review rhythm are agreed before the build.
- Scope
- Custom fixed or phased, set in the proposal
- Timeline
- Agreed after scope, access, dependencies and acceptance criteria
-
You provide
- The product
- Approved designs, or where the design stands and who is finishing it.
- The first release
- The workflows, roles and rules it must hold, and what can wait.
- The systems
- The APIs, data sources and services the app has to work with.
- A product owner
- One person who answers questions and accepts each slice.
-
Who does what
- ANODA
- Scopes the build, designs the architecture, writes and tests the code, releases it and hands it over.
- Your team
- Makes the product calls, provides access and data, reviews each slice and decides when to go live.
- Your providers
- Run the hosting, payments, identity and other services the app connects to.
-
Boundaries
- Outside web app development
- Designing the product from scratch, marketing websites, native mobile apps, content and third-party fees.
- After release
- Fixes, new features and support can continue with us on a separate scope, or your engineers take over. The code stays yours either way.

Web App Development: common questions
How do we choose a web application development company, and what evidence should we ask for?
Ask to see software the team built and released, not only designs — a design portfolio says nothing about how an app is engineered. Ask who wrote the backend, how permissions were tested, how a failed payment is handled and how a bad release is rolled back. Ask for sample acceptance criteria and a past handoff document. And check that you own the repository and cloud accounts from day one.
What do your web application development services include?
A technical scope with acceptance criteria; the architecture, data model and API design; the frontend and backend for every workflow in scope; sign-in, roles and permissions; integrations with payment, email, identity and your own systems; moving existing data in; automated tests and a deployment pipeline; quality checks; and a staged release with monitoring and a rollback path, followed by the handoff. The stack is agreed in the scope, not fixed in advance.
When is web app development the right service, and when should we start elsewhere?
Start here when you know what the product must do, you have decided to build it, and the screens are designed or will be by the time the build starts. If roles, flows and screens are still open, start with Web App Design; design and build can also run as one engagement. If your team runs the backend and only needs the interface, Frontend Development is enough. If the first job is to test demand with the smallest possible product, start with MVP Development. If it is not yet clear what to build, Product Discovery comes first.
Do you build C2C marketplaces and B2B2C platforms?
Yes. C2C marketplace development and B2B2C app development add work a single-sided app does not have: several roles with their own rules, listings and search, split payouts, seller checks, reviews, disputes and moderation. How each side experiences the product is a Marketplace Design question; the build is about who owns what. We build the listings, payment flows, payout logic and admin tools. The payment provider runs seller onboarding, identity checks and the payouts themselves, and your team owns the policies, fees and dispute decisions.
What do you need from us before the build starts?
Approved designs, or a clear view of where the design stands; the workflows, roles and rules the first release must hold; access to the APIs, data and services the app has to use; a cloud account or a decision on one; and one product owner who can accept each slice. If some of this is not ready, the architecture and foundation can start while it comes together.
How do you handle security, performance and accessibility?
As written acceptance criteria agreed before the build, not promises made after it. Typical criteria: access checked role by role, secrets kept out of the code, dependencies scanned, a speed budget for key screens, the accessibility level to meet, alerts that reach a named owner, a backup restored at least once, and a rehearsed rollback. Each release is checked against them, and the results are part of your test evidence.
What do we get at handoff, and can you keep working on the product afterwards?
The source code in your repository, the app on your cloud account, documentation of the architecture and integrations, test evidence, release notes, a runbook for deploys and incidents, and a map of who owns what after release. Then your engineers can take over, or fixes, new features, usability testing or design work can continue with us, each on its own scope.
What drives the scope, timeline and price of custom web application development?
The number of workflows and roles in the first release, how complex the permissions and business rules are, how many services the app connects to and how well documented their APIs are, whether existing data has to move, the quality criteria you need, and how ready the design is. We set a custom scope and estimate in the proposal, fixed or phased, and agree the timeline once scope, access, dependencies and acceptance criteria are clear. A phased scope often suits: the foundation and one core workflow first, then the rest.
What is not included unless it is scoped separately?
Designing the product from scratch, marketing websites, native mobile apps, content, and the fees, approvals and account actions of your cloud, payment and other providers, which stay in your name. Integrations are built to fail safely, not promised never to fail. We guarantee no user or revenue figures, and no security, compliance, performance or uptime level beyond the criteria agreed in writing.
Can we see a web app you have built?
Payyro is a platform we designed and then built: a crowdfunding product where donors pay families' overdue bills directly to landlords and utilities, with four roles in one app. It went from a UX audit to a first release, built low-code on Webflow and Wized. The redesign is now in development as a second version in Next.js, React, Node.js and Supabase. Most of our other published web app cases are design work, and we show them as design, not as proof of a build.
