What does it mean to build a web app and its automation as one project?

It means one team designs the screens people use and the background work that keeps your other tools in step, as a single plan, instead of hiring a web developer and an automation specialist who never meet. The web app is what your staff or customers click on. The automation is what happens behind it: sending the invoice, updating the CRM, notifying the right person, checking that nothing was missed.

When these are built separately, the gaps between them are where things break. When one team builds both, every button in the app has a defined result in your other systems from day one.

When do I need a custom web app instead of a spreadsheet or a no-code tool?

You need a custom web app when the work follows rules that are specific to your business and a generic tool forces your team to bend around it. Typical signs: a spreadsheet only one person understands, a form that has to be re-typed into another system, or a calculation that takes your best person a chunk of every day.

  • The same data is typed into more than one place.
  • Your pricing or approval rules do not fit any off-the-shelf product.
  • Customers or staff need a login to see only their own information.
  • A tool you rely on is slow, capped, or charges per user for features you do not need.

If an existing product already does the job, we will tell you so in the diagnostic. We do not build what you can buy.

Which parts are the app and which parts are the automation?

The app holds what people see and decide: forms, dashboards, estimates, approvals, customer logins. The automation holds what should happen without anyone remembering to do it: moving a finished job into accounting, creating a task, sending a confirmation, raising an alert when something fails.

We draw that line together in the first week. A good rule is that a person should only ever make a judgment call, and everything repetitive around that call should run on its own. For the automation side we mostly use n8n, and we connect the app to the tools you already run through our tool integration work.

What does the automation behind a web app actually do?

It keeps your other systems in step with the app and tells you when something goes wrong. When an estimate is approved in the app, for example, the automation can create the job in your field-service software, send the customer their copy, and log it in your CRM, all without a person copying anything across.

Every automated path we build has a failure route: if a step does not complete, a person is told what failed and why, instead of finding out weeks later from a customer.

Who owns the code and the accounts?

You do. We build inside your own accounts for hosting, database and automation from day one, and hand over the code and the documentation. If we ever part ways, nothing has to be rebuilt and you can take it to another team at any time.

We work in fixed-scope milestones, so you see working pieces as they are finished rather than a big reveal at the end.

How do you keep the app safe to change after it launches?

By building automated tests around the parts that must never silently break. On a prescription platform we rebuilt, the finished system ships with 173 automated tests, so a change made tomorrow cannot quietly break something that has to work today.

Monitoring is part of the build, not an add-on: the app and its automations are watched in the background, and we know about a failure before your users do. You get 30 days of support after launch, and an optional monthly retainer if you want us to keep watching.

How fast can a first version be live?

For a focused tool, quickly. An estimating tool we built for a construction company went live within 2 weeks of a one-week on-site session where we mapped how the work was really done. Larger platforms are staged in phases so something useful is working early.

The timeline depends on how many systems the app has to talk to and how many rules it has to carry. You get a scoped plan and a timeline before you commit to anything.

Has this been built before, as one project?

Yes. For a construction company we built an estimating tool as a web app with the automation behind it: estimates dropped from over 20 minutes to under 3, which frees up more than 325 hours a year, and the whole thing was live within 2 weeks after a one-week process-mapping session.

For a European online-prescription business we rebuilt the whole platform and both public sites, locked it down with 173 automated tests, and relaunched with 0 dead links across 4,772 checked.

How does a combined app and automation project run?

  • 1
    Map the real process first.

    We sit with the people who do the work, find which steps are judgment and which are repetition, and agree the screens and the automatic steps in writing before any code is written.

  • 2
    Build in working pieces.

    You see a working version early on your real data. Each milestone is fixed in scope, with the app and its automations tested together.

  • 3
    Launch, watch, and stay.

    Monitoring and failure alerts are live from day one. 30 days of support are included, and an optional retainer covers ongoing changes.

What does a custom web app with automation cost?

Custom web app with automation
Priced per project

What sets the price is how many screens, rules and connected tools the project needs. We scope it in the diagnostic and agree a fixed price before work starts. 30 days of support included.

Frequently asked

Can you build only the automation, or only the app?
Yes. Many projects start with one half. We design them to work together either way, so the other half can be added later without a rebuild.
What if we already have a web app?
We can add the automation behind it, or fix the connections between it and your other tools. The diagnostic starts with what you have and what is breaking.
Will the app connect to the tools we already use?
Yes. We connect it to your CRM, accounting software, field-service tools and spreadsheets, and the diagnostic confirms which ones are involved.
Who owns what you build?
You do. We build inside your own accounts, hand over full documentation, and if we ever part ways you keep everything.
What happens if it breaks after launch?
Everything we build ships with monitoring that alerts us before your users notice. You also get 30 days of support included, plus an optional monthly retainer.
What if you disappear like our last developer?
We have built systems for 13 years across 1,584 projects, with 200+ n8n workflows and 89 AI agents and model-driven automations in production. You hold the code, the accounts and the documentation, and NDA and escrow are available on request.
Can we start small?
Yes. Most clients start with the one screen or the one automation that costs them the most, watch it work, then expand. The free diagnostic tells you which one that is.

Priced per project. You see the number before anything starts.

Book a 30-minute diagnostic. We will map what the app needs to do and which of your tools it has to talk to, then give you a fixed price. The call is free and the plan is yours to keep. If we go further, the next step is a paid discovery.
