AI pricing comparison
AI pricing checks that show you every changed line
When a contractor resubmits a price or a payment claim, the total can look the same while rates move underneath it. We set up a workflow that compares submissions line by line and lists every difference, so a person decides what to accept.
Where this time goes
Hundreds of lines
A priced bill or a payment claim runs to hundreds of lines, and checking them by eye takes days.
Totals that hide changes
A total that matches the last submission can still hide rates that went up in one section and down in another.
Two formats
Each submission arrives in its own layout, so lining them up is a job before the checking starts.
Hard to explain later
Without a written record of what changed, it is hard to show why a figure was queried.
How the workflow runs
- Load both submissions. The earlier and the new pricing, or the claim and the contract rates.
- Line them up. Items are matched across the two, even when the layout differs.
- Compare every line. Quantities, rates, section totals and adjustments are checked against each other.
- List the differences. A report shows each change, including ones that net out in the total.
- A person decides. The project manager or quantity surveyor reviews each difference and decides what to accept or query.
Example
Our own practice · internal use
Two pricing submissions, one total, many changed rates
This workflow was built for our own construction project management practice and is used internally. It is not a client engagement.
The task was to establish what changed between two contractor pricing submissions. We built a line-by-line comparison of quantities, rates, section totals and adjustments. The result was a report showing where rates changed, even though the overall submission total stayed the same.
This describes what was built, not measured results.

What stays with your team
The decision
What to accept, query or reject stays with the person responsible.
The contract
The workflow reports differences. It does not interpret the contract.
The figures
Your source documents are never changed.
Professional sign-off
Certification and valuations remain with the authorised professional.
