What Does AI Estimating Cost? What You Pay and What You Get

Ask what AI estimating costs and you usually get a monthly number first and the rest later. The bigger cost isn’t on any pricing page. It’s your time: days preparing quotes you may not win, and hours checking AI answers you can’t trace.

Here’s what you pay with us, who you pay, and what you get.

What does AI estimating cost?

Two things: the setup, and the AI account it runs in.

We set up an estimating plugin in your own business Claude or ChatGPT account. The setup is a fixed fee, confirmed on your call, set up around your process and tested on your completed jobs. Your Claude or ChatGPT plan is paid directly to them, not us.

What do you pay, and who do you pay?

Cost	Amount	Who you pay	When
Estimating setup	Fixed setup fee, confirmed on your call	Us	Once, for the agreed setup
Claude or ChatGPT business plan	Their current plan price	Them, directly	Their subscription terms
Ongoing work (optional)	our implementation hours, agreed in a proposal	Us	Only if we agree monthly priorities, under its own proposal
Your time	Someone who knows how you price a job	Nobody, but plan for it	During setup

It needs to be a business plan on either, so files stay in your company’s account. We confirm which on the call.

What do you get for the setup fee?

An estimating plugin set up around your business:

• Done-for-you setup and handover. Proven on 3 of your completed jobs, then your team is walked through it.
• Set up from files you already have. Three quoted jobs, your pricing sheet and quote template. Messy is fine. No pricing sheet? We set one up with you; you confirm every figure.
• A complete BOQ template in your layout, sections and units.
• A complete pricing template with your rates, labour and markups as rules.
• A complete quote template on your letterhead, costs and markups kept off it.
• 15 estimating stages, tender pack to quote.
• Fully customisable. Change rates, rules, templates and workflow any time.
• You own everything. Plugin and files, in your own account.
• Works with files where they live, on your computer or synced from SharePoint, OneDrive, Google Drive or Dropbox. Workbooks open in Excel or Sheets.

At handover your team gets a walkthrough, a recording and a step-by-step guide. It keeps working when we’re not around.

Sample data. A sample handover checklist: each check sits beside its evidence, and automated checks don’t replace owner acceptance.

What does a one-prompt AI estimate really cost?

On paper, almost nothing. Drop drawings into ChatGPT or Claude and get a spreadsheet in seconds. Then: where did that count come from? Was that run measured or made up? Those rates aren’t yours. To trust it, you redo it. More in can ChatGPT or Claude do construction estimating?

That’s the hidden cost: your estimator checking numbers with no trail. What you pay for in a setup is the process around the AI:

1. Measure. It registers every document and revision and fills the BOQ in your layout. Each line shows its source, tagged measured, calculated, allowance (with its rule) or flagged. Nothing guessed.
2. Approve. Your estimator checks instead of redoing, and signs off the BOQ before pricing.
3. Price. Your rates, each with source and date. Missing rates listed for you. An internal pricing workbook and a draft quote on your letterhead.
4. Addenda. Addendum in, change schedule out, with before-and-after excerpts and the price difference.

Is there an ongoing fee?

Not for the estimating setup. If useful ongoing work follows, we can agree monthly priorities and a set number of implementation hours, for dashboards, integrations or support. Each needs its own proposal. Nothing by default.

And because everything is editable, you don’t need us to change a rate or markup.

How do you know it’s worth it before you rely on it?

We prove it on your completed jobs. You give us three priced jobs. We run the first with you, line by line, then lock the setup and run the other two without seeing your numbers. The target is every row and the price matching to the cent. Where it differs, we show why and fix the rules, never the answer.

You keep quoting as now and switch once it matches your jobs.

How much of your time does setup take?

No one technical needed. Just someone who knows how you price. They send files, answer questions and check the first job with us. We do the rest.

Is it worth a look?

If you quote commercial work from drawings and estimating eats your evenings, yes. A fixed setup fee, confirmed on your call. Your Claude or ChatGPT plan paid directly to them.
