Build a small online tool for your business

A small online tool is not “becoming a tech startup.” It is often: replacing a spreadsheet, a notebook, or five poorly glued tools… with a tool of your own, available in the browser, shaped for how you work.

Typically: you (or you + an assistant), sometimes clients who see a part. If you are aiming more at a work tool for the team (tracking, approvals, permissions): Build an internal tool for your team.

Examples:

• tracking client requests (quote → in progress → delivered)
• field visit planning
• quote calculator / business checklists
• tracking cases or deliveries

When it is really worth it

Yes, if you recognize at least two points:

• you repeat the same gestures every week
• information is scattered (email, WhatsApp, Excel, notes)
• a data-entry mistake costs time or money
• you want to find a case in 10 seconds, not 10 messages

Not yet, if:

• the need changes every week with no rules
• a simple form + spreadsheet still works fine
• you do not have a regular flow yet

In that last case: How to build a website or app with AI.

Tool ≠ presentation site

If the tool must remember information: What is frontend and backend? → on Index10, Index10 Cloud.

Concrete example: tradesperson / service provider

The headache today: quotes sent by email, follow-ups in WhatsApp, “where is the Martin job?” nowhere to be found.

A useful first version:

What you do not do on day one: full invoicing, online signatures, mobile app.

The idea is to start small: What is an MVP?.

Start from everyday headaches

Do not begin with a feature list. Start from what wastes your time, and ask for the screen that fixes it:

• You forget to follow up on quotes → a list “sent more than 7 days ago”
• You have a visit tomorrow → a simple schedule, not a giant software suite
• You tick a job checklist → checkboxes right on the record, without opening another tool

And use the words of your trade: “job,” “session,” “case”… the same ones you already use every day.

Start with a simple first version

When I open the tool, I must be able to find a quote or a job in under 2 minutes.

For this first version, stick to the basics: a list, a detail page, a create button. Two or three statuses are enough. No stats dashboards on day one.

How to do it on Index10

1. Explain your real day to the AI (like the tradesperson example above).
2. Let it build, then click through the preview to check it feels right.
3. If you need to sign in and the tool must keep your info: enable Index10 Cloud.
4. Test with about ten real-life examples (real quotes, real visits…).
5. If a client can sign in: create a second account and check they cannot see other people’s info.
6. Publish to get a link to share.

Later, if you connect online payments or automatic emails, you may be asked for a secret code. Never paste it in the chat: store it in the Cloud tab, under Secrets (a vault made for that). Details: Index10 Cloud · Security.

How to phrase your request: What is a prompt?.

Example starter message

Create a small online tool for a tradesperson. I need to create a quote, see where it stands, and mark it when delivered. Simple, readable design. No complex dashboard.

Common mistakes

• Copying Excel as-is, cell by cell
• Too many “just in case” fields
• Wanting online payments, auto-emails, and a mobile app on day one
• Pasting a secret code (payment, email…) in the chat
• Building a team tool without reading the internal tool guide

After that?

When the tool is used every week:

• an export for your accounting
• one useful automatic reminder
• a client area if the client must see “their” info

In short

A small tool succeeds when it saves you real time: one main action, few screens, and Cloud only when you need to keep information.

The right question: which gesture do I want to stop doing by hand this week?
