Web application development

Software built for the way your business actually works.

Customer portals, booking systems, dashboards and internal tools, designed and built by a team with years of experience in healthcare and fintech, where software has to be reliable, secure and simple for people who aren’t technical. One fixed price for a fixed scope, and you own the code.

What counts as a web app?

Anything your customers or your team log in to and use to get work done. A few of the shapes it takes for small businesses:

A customer portal

A place your customers log in to see their orders, documents, appointments or account.

A booking or quoting tool

Visitors pick a slot or build a quote themselves, and you get a clean record instead of a phone tag.

An internal dashboard

The spreadsheet your team lives in, turned into something several people can use at once without breaking it.

A workflow tool

Intake, approvals, scheduling, invoicing: the steps your business repeats every day, made faster and harder to get wrong.

We build for all kinds of businesses, and know two areas especially well: healthcare software, from pharmaceutical ordering to practice tools, and marketplaces and platforms that bring two sides together.

Do you need a website or a web app?

A website tells people about you

It explains what you do and gets you contacted. One page is often enough. That’s the $1,000 landing page.

A web app does work for you

People log in, data is stored, and something happens: a booking, a payment, a report. That’s custom software.

Not sure which you need?

Tell us the job you want done. If a page will do it, we’ll say so. The app is only worth it when it saves real time or earns real money.

Weighing a single page against a bigger site? Our guide to landing pages vs. websites walks through when each one makes sense.

Built so you’re never stuck with us

Everything is documented as we go, so if you hire developers later they can take over without starting from scratch. You own the code, the accounts and the know-how. Have a technology in mind? See your stack, or ours below.

How a project runs

  1. 01A short discovery callWhat the business does, where the time goes, and what “done” looks like. Thirty minutes, no slides.
  2. 02A written scope and a fixed priceThe screens, the rules, the integrations and what’s out of scope, with one price for all of it.
  3. 03Build, with weekly check-insYou see working software every week, not a reveal at the end, so changes are cheap while they’re small.
  4. 04Launch, then careWe launch, hand over the logins and documentation, and keep it running: hosting, backups, updates and support.

What it costs

Every web app is different, so there’s no flat price. There is a fixed one: after the discovery call you get a written scope and a single price for all of it, before any work starts. Hosting and care after launch are a monthly plan agreed at the same time. Our guide to what websites cost in 2026 shows where the money goes, and when a bigger build is worth it.

If the job can be done with a page instead, we’ll tell you, and point you to the $1,000 landing page or a WordPress site.

Your stack, or ours.

Have a vision for the technology, or a team that already works in something? We build in it. If you don’t have a preference, we’ll recommend tools that are well supported and easy to hire for, and explain the choice in plain English. Here’s what we work with:

Cloud and code

Where your app runs, and where its code is kept.

  • Amazon Web Services
  • Microsoft Azure
  • Oracle Cloud
  • GitHub
  • GitLab

Languages

What the app itself is written in.

  • Python
  • JavaScript and TypeScript
  • Go
  • Rust
  • C#

Data and AI

How your information is stored, and put to work.

  • SQL databases
  • NoSQL databases
  • Data lakes and lakehouses
  • Machine learning
  • AI and LLM features

Don’t see yours? Ask on the discovery call. Whatever we build in, it’s documented so your own developers can take it over.

Web apps we’ve built

Recent projects: the problem each business had, what was built, and what changed.

  1. Web application · Pharmaceutical wholesale

    The Med Hub

    A wholesale ordering platform where licensed pharmacies apply, order and pay online.

    The problem
    A licensed pharmaceutical wholesaler needed to sell to pharmacies online. Every order depends on compliance: a current state licence, DEA registration for controlled drugs, stock that hasn’t expired, and a credit limit.
    What we built
    A public site, a portal where pharmacies apply, order and pay, and an admin desk where staff vet applications, run inventory by lot and ship orders. Invoicing, returns and recalls are built in.
    The outcome
    The whole wholesale cycle runs in one system, from vetting a new pharmacy to recording its payment. The compliance checks are enforced by the software on every order, not left to memory.
    • React
    • TypeScript
    • NestJS
    • PostgreSQL
    • Prisma
    • AWS Fargate
    • Terraform
  2. Web application · Fractional executive marketplace

    Infinia

    A marketplace that introduces growing businesses to vetted fractional CFOs, COOs, CROs, CMOs and CTOs.

    The problem
    Founders need part-time senior leadership without a long search, and fractional executives want a steady flow of qualified introductions. Infinia needed a fair, explainable way to decide who meets whom.
    What we built
    A public site where founders describe their challenge and executives apply, a portal where executives set their criteria, fund a balance through Stripe and set a max bid, and a staff desk to vet leads and watch every match live.
    The outcome
    Each introduction is decided by an automatic auction and recorded with the reason it was won. Staff can explain any match, and executives can see what a higher bid would have bought them.

Frequently asked questions

Can you build in the technology our team already uses?
Yes. Tell us the stack you use or want to hire for, and we build in it. If you don’t have a preference, we recommend well-supported, widely known tools so it’s easy to find developers later. Either way, the code is documented for whoever takes it over.
How much does a custom web app cost?
It depends on the scope, which is why every project starts with a short discovery call and a written scope. You get one fixed price for that scope before any work begins, and the price doesn’t move unless the scope does.
How long does it take?
A small tool with a handful of screens is usually a matter of weeks. Larger systems take longer, and the scope document says how long before you commit. You see working software every week either way.
Who owns the code?
You do. At launch you get the source code, the hosting accounts in your name, and documentation for whoever works on it next.
Can it connect to the software I already use?
Usually, yes. Most modern tools, from payment processors to calendars and CRMs, have an interface we can connect to. We confirm each integration during scoping, before the price is set.
What happens after launch?
We keep it running: hosting, backups, security updates and support, on a monthly plan agreed up front. If you’d rather host it yourself or hand it to another team, the handover makes that straightforward.
Do I need a web app, or just a better website?
If the job is to tell people about you and get contacted, a website does it, and our landing page is a flat $1,000. A web app earns its keep when people need to log in, store data, or have something happen automatically.

Work with PageSimple

Tell us the job. We’ll tell you what it takes.

A thirty-minute discovery call, then a written scope and one fixed price. No obligation, and if a simpler website would do the job, we’ll say so.
