Historical pricing comparison

Reviewing a £180,000 quote against a £229,000 result

An early pricing comparison showed a material difference between a builder’s existing quote and a later Quotify output. The source record calls for a more careful interpretation of that gap.

The starting point

A builder had already prepared a quote and wanted to test Quotify against it. Internal discussion recorded a £180,000 figure as the starting comparison.

How Quotify was used

The internal account describes an initial Quotify result of £279,000, followed by a later result of £229,000. The follow-up discussion asks what lay behind the difference and whether missing scope had actually been identified.

A subsequent clarification says the builder had already quoted before making the comparison. The sequence matters when interpreting what the exercise achieved.

What came out of the review

The difference between £180,000 and the later £229,000 result is £49,000. That is a substantial variance to investigate, but it is not itself evidence of additional profit or revenue.

The available source record supports a pricing-comparison story. It does not establish that the revised figure caused the builder to win work or recover a particular sum.

Read the result in context

A price difference needs an explanation

The final scope reconciliation, original estimate reports and accepted contract value were not verified in this review. The variation between the first and later outputs also needs explaining before the comparison can be treated as a repeatable benchmark.

The available evidence does not establish protected margin, recovered revenue or a change to an accepted contract price.

What another builder can take from it

When two estimates differ materially, trace the difference to specific scope items, rates and commercial assumptions. Keep the accepted contract price and actual profit separate from the size of an estimating variance.
