Pre-plan cost estimating · for custom home builders

The rough number, done right.

A real budget in the first meeting — before the architect gets involved, before the drawings exist, before your client falls in love with something you can't afford.

◇ the problem

The conversation before the estimate.

Every custom-home conversation reaches the same awkward moment: the client asks "so what are we looking at?" — and you have no honest answer to give them, because the drawings don't exist yet.

You can either guess high and scare them off, guess low and regret it, or promise to "get back to them next week" and watch the project lose momentum. Ruffbid gives you a real number to put on the table right now.

Builder"Hard to say without drawings. Let me put a number together and get back to you next week…"
Client"…okay. Let me know."
◇ the stakes

Every week you punt is a week the number drifts.

Pre-plan hesitation isn't neutral. Material costs are moving, competitors are closing, and your client's mental anchor is getting further from reality.

+40%
Construction material costs, 2020 → today

The BLS Producer Price Index for construction inputs is up roughly 40% from its 2020 baseline. Clients walking in with a number they heard 2–3 years ago are badly mis-anchored.

Pricing clarity as a builder-selection factor

Industry surveys consistently show clients rank clear pricing alongside quality and communication as top reasons they pick one builder over another. They don't need a cheaper builder — they need an honest one.

How most small-to-mid builders still estimate

NAHB member surveys show the typical small-volume custom builder still puts pre-plan numbers together in a spreadsheet plus tribal knowledge. Every hour there is an hour not on-site, not in a sales conversation.

◇ your upside

One additional signed contract pays for years of Ruffbid.

Typical custom-home gross margin~15%
On a $1M build≈ $150K gross
Hours saved per pre-plan lead3–6 hrs
Ruffbid cost vs. one additional contract< 0.1% of margin won

We won't promise a close-rate lift — that depends on your market, your pricing, your close skills. What we promise: every pre-plan meeting ends with a real number on the table, not a promise to follow up.

◇ how it works

Four minutes. One number. In the room.

No drawings, no spreadsheets, no "I'll get back to you." Answer the same questions you'd ask a client anyway, and Ruffbid assembles the estimate as you go.

01

Size & site

Heated square footage, number of floors, ZIP code. Ruffbid pulls your regional cost index and your own calibrated baseline.

02

Program

How many bedrooms, bathrooms, kitchens. One big space or many small? Pick a tier — basic, standard, premium, luxury.

03

Tune

Bump up the kitchen, dial down the exterior, add a scope note. Every nudge re-prices in real time.

04

Share

A branded PDF with your logo, or a live link the client can open on their phone in the room. Saved with the project.

◇ the product

A budget that moves with the conversation.

Everything is live. Change a tier, drag a room's price, swap a finish — the total and the range update instantly. You're not waiting on a spreadsheet to recalculate; you're designing a budget out loud.

◇ what builders say

Pre-plan meetings that end with a yes.

"I used to spend three hours building a spreadsheet the night before every pre-plan meeting. Now I do it in the room, in front of the client, while we're talking. They leave with a number — not a promise to get back to them."

Ryan HalvorsenHalvorsen Build Co. · Portland
"Our close rate on pre-plan meetings went from 30% to 62% in six months. People don't buy a feeling. They buy a number."

"The ranges are what sold me. My clients stopped hearing one number and forgetting the rest. They hear the whole shape of the project."

◇ frequently asked

Things builders ask before their first estimate.

Is this replacing my real takeoff?

No. Ruffbid is for pre-plan — the first conversation, before drawings exist. Your real takeoff still happens in your existing tool after you have CDs. Ruffbid just lets you answer "what are we looking at?" without punting to next week.

How accurate is a pre-plan estimate?

Our median variance from final permit-ready cost is ±6%. For a well-calibrated builder running Ruffbid for six months, that drops to ±4%. Accuracy compounds — every closed project sharpens your baseline.

Where does the cost book start?

You pick a starting region (Portland, Denver, Austin, etc.) and Ruffbid preloads RSMeans-indexed baselines. From there, every estimate you close to permit tunes those numbers toward your actual costs.

Can I show this to a client?

Yes. The PDF and shareable link are branded with your logo, your colors, your name. The client never sees “Ruffbid.” They see Halvorsen Build Co.'s estimate — as it should be.

Does it work on a phone?

It's designed for a phone first. The whole pitch is “pull it up at the kitchen counter.” The desktop app is the same product with more screen real estate.

What if my clients want a single number?

Most do, and that's fine. The range is a tool for you — so you know where the risks are. The client-facing PDF can hide the range and show only the most-likely total. Two clicks in Settings.

Never say "let me get back to you" again.

Free for 14 days. Your first estimate takes four minutes.
