Construction Estimating · by voice

Estimating that talks back.

Build a bid by talking. Charlie holds your cost library, guards your margin, drafts the clauses, and hands you a branded proposal — then tells you whether the job's even worth chasing.

The bid's due at 2, and you're still in a spreadsheet at midnight. Estimating software makes you learn the software. Charlie doesn't. You talk through the job the way you'd tell a foreman, and the estimate builds itself — priced from your own library, checked against your own margin floor, with the exclusions and assumptions already written in.

The estimating drawer

Everything a bid needs — spoken, not typed.

A full estimating suite that happens to run by voice. Nothing to learn, nothing left off the proposal.

📚

Your cost library

Material, labor, equipment and sub costs — your numbers, priced per unit, snapshotted onto every line so a library edit never moves an old bid.

🛡️

Margin-floor protection

Set your minimum margin once. Charlie warns — or blocks the submit — when a bid drops under it. You never accidentally give one away.

🔀

Alternates & add/deducts

Roll alternates as a flat number or from grouped line items. The proposal shows each one, priced, ready for the owner to pick.

📝

Clause drafting

Inclusions, exclusions, clarifications and assumptions — Charlie drafts them from the job so nothing you meant to exclude ends up in your scope.

🎯

"Should I bid this?"

Point Charlie at the bid docs and he screens the job against your qualifications — bond limits, insurance, scope fit — and gives a GO / CAUTION / NO-GO with citations.

📐

Ask your plans

Upload the drawings and specs. Charlie answers questions from them — with the section and page — so you bid what's actually in the documents.

See the output

The proposal your client actually gets.

Clean, professional, on your letterhead — price, scope, alternates and clauses, ready to send. Your internal costs, markups and margin never appear on it. Charlie builds this from the bid you just talked through.

The part other estimating tools skip

The best bid is the one you don't waste a week on.

Every other estimator starts you pricing. Charlie starts you qualifying. Feed him the invitation, the specs, the bond and insurance requirements, and he tells you whether you should even chase it — before you burn a day on a job you can't win or shouldn't want. Bid the right work, win more of it.

From the truck

Bid while it's fresh.

You just walked the site. Instead of carrying it back to the office in your head, you tell Charlie right there — and the estimate's already started before you turn the key.

Straight answers

Questions, answered.

Do you give me prices to bid with?

No — and that's on purpose. Your unit costs, markups and margins are yours. Charlie never ships prices or sets your numbers; he holds the library you build and does the math on it. Your pricing is your edge, and it stays private.

Can it read my plans and specs?

Yes. Upload the drawings and specs and Charlie answers questions from them — with the section and page cited — and screens the job against your qualifications before you bid.

Do I have to learn new software?

No. You talk through the job the way you'd explain it to a foreman. Everything also works by tapping if you'd rather — voice and touch, your choice, on any device.

What happens when I win the bid?

On Full Charlie, a won estimate becomes the job budget automatically — your bid total is the contract value and your hard costs split into job-cost categories, so your planned margin carries straight into the field.

Can I start with just Estimator and upgrade later?

Yes. Estimator is $149/mo on its own. When you're ready for payroll, billing and the rest, upgrade to Full Charlie — no migration, your estimates and library come with you.

Is there a contract or setup fee?

Neither. Month-to-month, $0 setup, cancel anytime, and every plan is backed by a 30-day money-back guarantee.
