Working prototype

SurfaceBid

Property measurements, service scope, and itemized estimates

THE BUSINESS PROBLEMHow can a service estimator make quantities and pricing assumptions understandable from property selection to the estimate?
ACTUAL OUTCOME / CURRENT STAGEA prototype connecting address lookup, measurement, editable pricing and PDF output across two iterations of one product.

I researched the operating need, defined requirements, directed AI-assisted development, and reviewed the estimating journey and practical edge cases.

The problem

I examined how commercial-services estimating turns a property into a scope of work. The product separates what is being measured from the rates and adjustments used to price it.

My decisions

Match the method to the service

Support area, facade, count and manual scope rather than forcing every item into one measurement method.

Keep rates explicit

Use editable prices supplied by the estimator. The product does not make a rate an industry standard.

Explain the output

Carry quantities, units and pricing into an itemized estimate and PDF rather than showing an unexplained total.

Explore the workflow · Fictional example

An estimate is only as clear
as its quantities and assumptions.

Scenario A · Fictional

Area-based surface estimate

Assumed area1,200 sq ft
Illustrative unit rate$2.00/sq ft
Line total$2,400

Measurement method: manual sample quantity. Verify the actual surface before using an estimate.

Scenario B · Fictional

Quantity and rate revised

Assumed area1,500 sq ft
Illustrative unit rate$2.20/sq ft
Line total$3,300

The $900 difference follows from changed inputs. It is not measured revenue or savings.

The source summary below explains the measurement methods, editable rates and estimate output. These examples are not price recommendations or measurement-accuracy claims.

Selected source evidence, summarized for this portfolio. Newly authored examples use fictional data.

Measurement method is explicit

The service definitions identify area-based washing and sealing, facade work, counted items, and manual custom scope. The catalog defines the method and unit while keeping rates out of the catalog.

Source basis: SurfaceBid service definitions; inspected September 2026.

An estimate carries its assumptions

The estimating workflow and PDF renderer connect quantities and pricing to an estimate document. The fictional comparison shows the arithmetic for an individual line; taxes, adjustments and other scope are excluded from this example.

Source basis: SurfaceBid estimating session and PDF rendering source.

The working prototype makes a service workflow tangible for review. The original and 2.0 workspaces are iterations of one product. Paid adoption, certified measurement accuracy and measured savings are unverified.
