For general contractors

Compare subcontractor bids side-by-side in minutes

Stop normalizing three different proposal formats into one spreadsheet by hand. Plotform extracts every line item from every sub bid and merges them into one comparison table — with deltas, scope gaps, and totals — so award decisions take an afternoon, not a week.

The old way vs. Plotform

Award decisions stall because comparison takes longer than the bids did.

The old way

  • Re-typing three sub proposals into one comparison spreadsheet
  • Discovering Sub A and Sub B price the same thing in different units
  • Missing the scope gap where Sub C left out the pump
  • Manually calculating deltas line by line
  • Spending a week on bid comparison when the schedule said two days

With Plotform

  • Upload three subs — normalized comparison table built automatically
  • Units reconciled across bids so comparison is apples-to-apples
  • Scope gaps surface as blank cells with a flag — nothing slips through
  • Deltas and totals calculated live — adjust any cell, watch totals update
  • Award the right sub in an afternoon with confidence in the numbers

What you get

Built for the way GCs actually evaluate bids.

Side-by-side comparison

Every sub bid normalized into one table. Lowest bid per line item highlighted; high bids flagged with delta values.

Scope-gap detection

Missing line items surface as blank cells with a flag, so you know exactly what each sub is and isn’t bidding.

Live edits & re-totaling

Adjust any rate or quantity in the browser; deltas and grand totals recalculate immediately. Export to Excel when you’re ready.

GCs awarding bids faster, with more confidence

What estimating teams are saying after switching.

Bid leveling was a full week of spreadsheet work. Now it’s an afternoon with cleaner numbers.

Scope gaps used to surface during construction. Plotform catches them before the award.

Three concrete bids reconciled in 40 minutes. Our subs noticed we were sharper this round.

How it works

Three steps from a stack of sub bids to an award-ready comparison.

01

Upload every sub bid

Drag in each sub proposal as a separate file. Up to 500 pages per bid.

02

AI extracts & normalizes

Every line item pulled out and merged into one comparison table — units reconciled, deltas calculated.

03

Award and export

Pick the right sub per scope, edit anything in the browser, then export an Excel award pack.

Who it's for

General contractors and the teams that buy out their jobs.

Frequently asked questions

Everything you need to know before getting started.

How does the side-by-side bid comparison work?

Upload each subcontractor proposal as a separate file. Plotform extracts the line items from each and normalizes them into one comparison table where you can see who is high, who is low, and what the dollar delta is per line and at the total.

Can it handle bids with different formats?

Yes — that’s the point. Whether a sub uses a clean BOQ, a narrative proposal, or an Xactimate-style line list, Plotform normalizes them into the same column layout so comparison is real.

What happens when a sub bid is missing a line item?

Missing line items show up as a blank cell in the comparison table, with a flag, so you can see exactly what scope gaps exist before awarding.

Can I edit pricing in the browser?

Yes. Adjust any cell in the comparison table — totals and deltas recalculate live. Export the result to Excel when you’re done.

How long does the full bid-comparison flow take?

Uploading three subs and getting back a comparison table typically takes 30–60 minutes end-to-end. Manual normalization of three bids is usually a full day.
