Build a free quote calculator that collects enquiries, then offer it to local businesses

In Google AI Studio's Build mode you describe a phone-friendly quote calculator for a service business. Visitors pick an option, see a price range and leave their details for an exact quote, and every enquiry is saved to a private admin page. Eligible personal Google accounts can publish up to two apps for free, with no card.

๐Ÿ’ธ What will this really cost me?

Prices checked 22 Oct 2026
๐Ÿงช To try it once
Free: eligible personal Google accounts can build and publish up to 2 apps from Google AI Studio with no billing account.
๐Ÿ” To keep it running
Free on the Starter Tier for up to 2 apps. More apps or more capacity need a Google Cloud billing account: check the provider's pricing page.
โš ๏ธ Watch out for
Workspace and school accounts, and anyone who has had a paid Google Cloud billing account, can't use the free tier. If the app calls Gemini, that usage runs on your API key's limits and is paid beyond the free tier.

โ„น๏ธ How we work this outPrices come from each provider's own pricing page (checked 21 Oct 2026; amounts exclude tax; USD 1 = MYR 4.08, Bank Negara Malaysia 19 Oct 2026). Small upgrade = up to MYR 250 a month more than you pay now. Big upgrade = more than MYR 250 a month more. Check pricing = the provider doesn't publish a price we could confirm. Each guide's needs come from its own "What will this really cost me?" box. Your ticks stay in this browser only (no account, nothing sent to us).

๐Ÿ’ฌ Copy-paste prompts

Tap Copy prompt, paste it into your AI (Grok, ChatGPT, Claude or Gemini), then replace the [yellow bits] with your own details.

๐Ÿ’ฌ Quote calculator app
Build a mobile-first quote calculator for my [service, e.g. home cleaning] business called [business name] in [town].
Visitors pick from these options: [option 1: e.g. 1-2 bedroom], [option 2], [option 3], plus [one extra, e.g. deep clean yes/no]. Show an instant price range in [currency] using these ranges: [ranges].
Then ask for their name, email or phone, and project details to get an exact quote. Show a thank-you message.
Save every enquiry in Firestore with the date and the options picked.
Add an admin page behind Sign in with Google that only [my email] can open, listing enquiries newest first.
Clean design, one accent colour [colour], no stock photos. Add a line under the price: 'Estimate only. We'll confirm your exact price.'
๐Ÿ’ฌ Short pitch (optional)
Write a short, friendly message (under 90 words) to [business owner's first name], who runs [business] in [town]. Say I built a free working demo of an online quote calculator for their kind of business, give the link [demo link], and say it saves every enquiry to a private page. Offer to set it up with their real prices for [my price, e.g. a one-off fee]. No hype, no made-up results.

โš ๏ธ Tips & common mistakes

๐ŸŒŸ Why it's worth it

๐Ÿ’ก Why it mattersMany small service businesses have no way to give a quick price online, so enquiries go elsewhere. A working demo built in an evening is something you can show a cleaner, tutor or photographer before you ask to be paid to set it up for them.
๐Ÿท๏ธ Real exampleNora Hustles (@NoraHustles) posted the method on 20 Oct 2026: open Build mode, paste a prompt for a quote calculator that saves leads and has an admin page behind Google sign-in, fix it by pointing at the preview, then publish to a free ai.studio address. She lists the limits: only 2 free published apps, not every account qualifies, and an app that calls Gemini uses your own key's limits. Google's AI Studio docs confirm the Starter Tier allows up to 2 apps without a billing account.
