# A custom business app for your team or your customers

Some businesses outgrow spreadsheets, group chats and a patchwork of apps that do not talk to each other. Jobs get lost, the team works from old information and customers have to call to ask simple things. We build a custom business app for your team or your customers, with bookings, jobs, quotes and notifications in one place, built around how your business actually works.

## The problem we fix

Generic apps make you work their way. Your process has its own steps, roles and exceptions, so the team ends up using three tools and a WhatsApp group to fill the gaps. Information is typed twice, things fall through, and nobody has the full picture.

## What we can build

- **A team app.** Jobs, schedules, checklists, photos and notes for the people on the ground, updated live.
- **A customer app or portal.** Bookings, quotes, job status and messages for your customers, without phone calls.
- **Quotes and approvals.** Quotes created, sent and approved in the app, connected to your pricing rules.
- **Notifications.** The right people told at the right moment: a new booking, a job done, a quote accepted.
- **Connected to everything.** Linked to your CRM, calendar, messaging and the tools you already use.

## How we work on it

- **Start from the process.** We map who does what, step by step, and design the app around that.
- **Build the core first.** The smallest version that removes the biggest headache, in your team's hands early.
- **Improve with real use.** We adjust based on how your team and customers actually use it.
- **Hand over.** The app and its data are yours.

## What your day looks like after

Your team works from one place, with current information. Customers can see what they need without calling. You can see the state of every job and booking at a glance, and the work that used to fall between apps stops falling.

A custom app often grows from a [custom CRM and dashboard](https://mountolympusai.cloud/custom-crm-and-dashboard/) and connects with [n8n workflow automation](https://mountolympusai.cloud/n8n-workflow-automation/). See [all our services](https://mountolympusai.cloud/services/) and the [Client Capture System](https://mountolympusai.cloud/client-capture-system/).

## Examples of apps we can build

A trades business might use a team app where each engineer sees their jobs for the day, adds photos and notes and marks the job done, which sends the customer a summary and a review request. A clinic might give patients a portal to book, see their next appointment and receive aftercare information.

We start with the one problem that costs you the most time and build from there, so the app earns its place before it grows.

## Questions

### Is it an app store app or a web app?

It depends on what you need. Many business apps work best as web apps that install on a phone's home screen. We will recommend the simplest option that does the job.

### Who is it for?

Your team, your customers or both. We design around the people who will use it every day.

### Can it connect to the tools we already use?

Usually yes, through direct APIs and workflow automation.

### Who owns the app and the data?

You do.

### How long does it take?

It depends on the scope. We agree the first version and its timeline on a short call, and nothing goes live without your approval.

### How is it priced?

As a setup fee plus a monthly plan, sized to the project. [How pricing works](https://mountolympusai.cloud/how-pricing-works/).
