To create an app for your business, start with the problem it solves, check whether an existing product already solves it, and only then build. If you do build, choose a web app unless you truly need app-store features, pick a path (an AI app builder, a no-code tool, or a freelancer or agency), write down the data and who can see what, build the smallest version that does the job, pilot it with a few real users, then launch and maintain it. For most small businesses, an AI app builder is now the cheapest route to a custom app: with Greta.sh you describe the app in plain English, it builds the frontend, backend and database, and deployment starts at $5/month as a welcome offer (normally $20/month).
Most guides on this topic assume you are building the next consumer app. Most business apps are not that. They are a booking flow for customers, a portal where clients see their orders, or an internal tool that replaces a spreadsheet three people edit at once. This guide is written for that kind of app.
First: do you need a custom app at all?
Before you build, check whether a product you can subscribe to already does the job. Buying is the right call when your process is standard: accounting, payroll, email marketing and most help desks are better bought than built. Building makes sense when:
- Your process is specific to you, and off-the-shelf tools force workarounds or several tools stitched together.
- You're paying for many seats of a tool to use a small part of it.
- The app is part of what you sell, such as a client portal or a booking flow that has to match your service exactly.
- Your data lives in spreadsheets that are getting too big or too shared to trust.
Our story on moving from SaaS sprawl to custom-built tools walks through how teams make that call.
What kind of business app are you building?
| Type | Who uses it | Examples |
|---|---|---|
| Customer-facing | Your customers | Booking and scheduling, online ordering, client portal, quotes and approvals, membership area |
| Internal | Your team | Inventory, CRM, staff scheduling, job tracking, approvals, reporting dashboards |
| Partner-facing | Suppliers, resellers, contractors | Order portals, document sharing, onboarding forms |
Naming the type early tells you who the users are, which decides the roles and permissions you need later.
Web app or mobile app?
For most businesses, start with a web app. It works in any browser on phones, tablets and computers, there is no app store review, and an update reaches every user at once. A native mobile app is worth it when you need things a browser does badly, such as heavy offline use or deep access to device hardware. Our guide to PWA vs native apps goes through the trade-offs, and what a web app is covers the basics.

Your options for creating a business app
| Option | Who builds it | Best for | Watch for |
|---|---|---|---|
| AI app builder | You, by describing the app | Custom web apps for small teams on a small budget | You still own testing and deciding what it should do |
| No-code builder | You, in a visual editor | Simple forms and data apps | Complex logic gets hard to maintain; check data export |
| Freelancer | A hired developer | A defined project with a clear spec | Ongoing changes depend on their availability |
| Agency | A team | Larger or regulated projects | The highest cost and the longest timeline |

How to create an app for your business in 7 steps
Step 1: Write the problem in one sentence
"Our [users] need to [do something] because today [what goes wrong]." For example: "Our café staff need to request shifts and time off because today it happens over text messages and the rota is always out of date." If you can't write this sentence, you're not ready to build.
Step 2: List the data and the roles
Write down what the app keeps track of and who can do what. For the café example: Staff (name, role, contact), Shifts (date, start, end, assigned staff member), Time-off requests (staff member, dates, reason, status). Staff can see the rota and request time off; the manager can create shifts and approve or decline requests. This list becomes your database and your permissions.
Step 3: Choose the smallest version that solves the problem
Pick the two or three screens that fix the sentence from Step 1. For the café: a weekly rota view, a time-off request form, and a manager's approval list. Notifications, reports and payroll exports can come later.
Step 4: Pick your path and build
With an AI app builder, you describe the app. A first prompt for the café app:
Build a staff scheduling app for a small café. Two roles: staff and manager. The manager creates shifts (date, start time, end time, staff member) and sees a weekly rota. Staff sign in, see the rota and their own shifts, and submit time-off requests (dates and reason). The manager approves or declines requests, and approved time off shows on the rota. Simple, clean design that works well on phones.
Then refine it with short, specific requests: "show each staff member's total hours for the week on the rota", "stop a shift being assigned to someone on approved time off". With a freelancer or agency, the same text becomes your brief.
Step 5: Pilot it with a few real users
Give it to two or three of the people who will use it every day, for a week. Watch where they get stuck, what they ask for, and what they work around. Fix the top issues before anyone else sees it. Our QA checklist for AI-built apps lists what to test.
Step 6: Launch on your own domain
Put the app on a domain you control (for example, rota.yourbusiness.com), make sure it loads over HTTPS, and decide who gets access first. Connecting a custom domain explains the DNS step.
Step 7: Maintain it like a product
Someone needs to own the app after launch: answering questions, fixing what breaks and deciding what comes next. Back up the data, add an error tracker and an uptime check (our error tracking tools roundup compares free tiers), and change one thing at a time.
Creating a business app with Greta.sh
Greta.sh is an AI app builder for founders, operators and small teams: you describe the app and it builds the frontend, backend, database and sign-in, then deploys it. Its site lists CRMs, admin panels, internal tools, dashboards, POS systems and database apps that replace spreadsheets among the things it builds. Plans, from greta.sh/pricing:
- Free: 5 credits a day and a code viewer, to build and try the app. The free plan does not deploy.
- Starter: $5/month welcome offer (normally $20/month), 100 credits a month, deployment, custom domain setup and web analytics.
- Pro: $20/month welcome offer (normally $50/month), 250 credits a month, adding the Database, Flows, version control with GitHub and team management, so colleagues can work on the app with you.
Two things to know before you start. Greta.sh builds its own database for the app; it doesn't plug into an existing production database, so plan to bring data in rather than connect to a live system. And Greta.sh's app templates give you a data model, screens and a starter prompt for common business apps, which is a faster start than a blank page.

What it costs to create a business app
The cost depends on the path more than the app. Subscribing to an existing product costs a monthly fee per user. Building with an AI app builder or no-code tool costs a monthly plan plus your time. Hiring a freelancer or agency costs the most up front, plus ongoing changes. Whatever you choose, budget for the running costs too: hosting, a domain, and the time someone spends maintaining it. How long it takes to build an app covers the timeline side.
FAQ
How do I create an app for my business for free?
You can build one for free on the free plans of AI app builders and no-code tools, and test it with your team. Putting it live on your own domain usually needs a paid plan. On Greta.sh, the free plan (5 credits a day) lets you build and see the code; deployment starts on Starter at $5/month as a welcome offer (normally $20/month).
Can I create an app for my small business myself?
Yes. With an AI app builder you describe what you need and it writes the code, so you don't need to be a developer. You do need to be clear about the problem, the data and who can see what, and you need to test it properly before your customers or staff rely on it.
How much does it cost to create an app for a business?
It ranges from a monthly plan, if you build it yourself with an AI or no-code builder, to far more if you hire a freelancer or agency. See how much it costs to build an app in 2026 for the breakdown by method.
Should my business app be a web app or a mobile app?
Start with a web app unless you need heavy offline use or deep device features. A web app works on phones through the browser, skips app store review, and every user gets updates at once.
How long does it take to create a business app?
A focused internal tool built with an AI app builder can be ready to pilot in days. Customer-facing apps with payments, several user types or integrations take longer, and anything built by an agency is usually measured in months.
Is it better to buy software or build a custom app?
Buy when your process is standard and a product already fits. Build when your process is specific, when you are paying for far more software than you use, or when the app is part of the service you sell.
Start with the one sentence
Write the problem sentence from Step 1, list your data and roles, and describe the app. Create your business app with Greta.sh: the free plan gives you 5 credits a day to try it.
