[ SCENARIOS ]

When a tool belongs on your site

Customers ring to ask what a job roughly costs, and the answer follows a handful of simple rules. An instant-quote calculator gives them that answer on the page.

You keep a comparison spreadsheet the whole industry would use if it lived on a page they could find.

You want leads qualified before they reach your inbox - a scoring quiz does the sorting. The agent readiness scan on this site is exactly this pattern, running live.

Sales rebuilds the same ROI calculation in a spreadsheet for every prospect, and every copy drifts a little further from the truth.

[ DETAILS ]

What an indexable page does that an iframe widget cannot

Widget builders charge $5–139 a month and render your tool inside an iframe: search engines can't index it, AI assistants can't read it, and the styling is theirs rather than yours. If the subscription lapses, so does the tool.

This build is ordinary code on your own URL: server-rendered, on-brand, readable by anything that reads HTML. It can rank for the queries your customers type, get cited by answer engines, and it never expires.

Specialist calculator services charge $900–$3,000+ per project, often with a platform subscription on top. The fixed $1,200 sits in the middle of that range and buys code you own outright - your five days go into your formula, your data and your brand.

    The acknowledgment

    Lands while you're still on this page. It plays your brief back and confirms what happens next:

    A written spec, then the quote

    Your brief becomes a one-page spec: the inputs, the formula or scoring rules, the outputs, and the one data source. The fixed quote prices that spec - and if the brief turns out to hide something bigger, you get a re-quote before the build starts, never a surprise after it.

    Terms: 50% deposit · balance on delivery · 1 revision round · 14-day warranty · valid 7 days

    The shape every quote takes. Yours is written against your brief, and anything in [brackets] becomes a real number before it reaches you.

  4. DEPOSIT

    You accept, the clock starts

    Reply to accept and the 50% deposit invoice follows. The build clock starts when the deposit and your materials land, and the ship date goes in writing the same day.

  5. DAY 1

    Spec and data

    The formula or scoring rules written down and agreed, the data source connected - a spreadsheet, an API or a config file - and a working skeleton on a preview link.

  6. DAYS 2–3

    The build

    The logic implemented with tests that prove the numbers against your own worked examples, then the interface built on-brand around it. The preview updates as pieces land.

  7. DAY 4

    Revise and wire

    Your revision round, then lead capture connected end to end and proven with a real submission arriving where you said it should.

  8. DAY 5

    Embed and ship

    Live as a page on your site, or the embed installed where it needs to go, with indexability checked so machines can read what you built.

  9. SHIP

    Delivery and handover

    The balance is invoiced on delivery. Repo and accounts transfer to you, my access goes away, and the handover email covers what shipped and how to change it.

  10. +14D

    The warranty window

    Bugs in what shipped are fixed free for 14 days from handover. After that you have the code, the docs and no dependency on me.

[ NOT INCLUDED ]

What's not included

What sits outside the price, so nothing is a surprise at the invoice:

  • A second tool - each gets its own scope and price
  • More than one data source - extra sources are quoted after a look
  • Keeping the data current over time - ongoing updates are quoted separately or automated via Automation Build
  • Accounts, logins or saved results - that's an application, quoted as one
  • Redesigning the page around the tool - that's the Launch Page package

One tool, one data source, one clear formula is the shape the price is built on. If yours is bigger, the quote says so before anything starts.

[ FAQ ]

Cost, embedding, data and ownership

How much does a custom calculator cost?

$1,200 USD fixed here, for one calculator, comparison table or scoring quiz with lead capture - shipped in 5 days with the code in your repo. The alternatives: DIY widget builders run $5–139 a month for as long as you use them and live in iframes, while specialist calculator services are quoted $900–$3,000+ per project, often with a subscription on top. The fixed price includes a revision round, and the quote you accept is the number on the invoice.

Can it go on my WordPress, Webflow or Squarespace site?

Yes. You get a single script file that mounts the tool into any page, plus a static summary block for the host page so search engines still have something to read. On a Next.js or similar codebase it drops in as a component, fully server-renderable - that's the strongest version for search.

What counts as one data source?

One place the numbers come from: a spreadsheet you maintain, one API, or rates written into a config file you can edit. A mortgage calculator reading one rate table is one source; pulling live prices from three providers is not, and gets quoted as what it is.

Will Google and AI assistants read it?

Yes, and that's the reason to build it as a page rather than an iframe. On a standalone page the tool ships with its inputs, copy and results structure in the HTML, plus structured data where it applies; builder embeds keep a static summary on the host page for the same reason. Run any page through the free scan on this site to see what machines currently get from it.

What happens when my formula or rates change?

The numbers live in a config file, separate from the code, so routine rate changes are edits you can make yourself. Formula changes are small quoted jobs - and if the tool misbehaves within 14 days of handover, that's warranty, free.
