AI contractor bid comparison that flags missing items and unusual prices
Phak AI's contractor bid comparison reads quotes from several contractors in PDF and lines them up item by item. It points out items some bidders left out and items priced far from the others. It suits project management consultants, project owners, and developer procurement teams. Your team always reviews the results and chooses the contractor.

Where manual contractor bid comparison gets stuck
Every bid is structured differently
Each contractor uses different work categories, units, and item names. Someone has to match them line by line.
Items go missing unnoticed
Some bids leave out part of the work. The total looks lower, but the extra cost shows up later.
Unusual prices hide in the details
Items priced unusually high or low are scattered across many pages. Finding them means reading the whole set.
The work falls on a few people
Bid comparison sits with a few engineers or quantity surveyors (QS), so other projects wait.
How AI contractor bid comparison works
Bid files are stored on a dedicated server for each organization. See security for details.
Upload the bids
Add each contractor's quote as a PDF, along with the BOQ or scope of work sent with the invitation, if you have one.
Match the items
AI reads the items from every bid and groups them under the same categories for a line-by-line comparison.
Flag what needs a look
AI points out items some bidders did not include and items priced far from the others, with the page in the source document.
Your team reviews and decides
Engineers or project managers check the results, ask contractors follow-up questions, and make the choice. To draft your own quotes, extend this with Smart Quote.

Questions teams ask when comparing bids
Clear boundaries
What Phak AI does
- Phak AI reads and matches line items across several bids
- Phak AI flags missing items and prices far from the others
- Phak AI points to the place in the source document for review
What it does not do
- It does not choose a contractor or decide for the project team
- It does not take off quantities from drawings. That is BOQ drafting work in Smart Quote
- It does not replace procurement, ERP, or accounting systems
Frequently asked questions
Do we need a master BOQ first?
It is not required. If you have the BOQ or scope of work sent with the invitation, it makes it clearer which bidders did not cover everything you asked for.
Can the AI tell us which contractor to choose?
No. AI makes the differences clear, but choosing a contractor depends on price, track record, and capacity, and that decision belongs to the project team.
Is contractor pricing data safe?
Files stay on a dedicated server for each organization and are never used to train AI models. Access is limited by role to the teams involved, and every question is logged.
Can we compare material quotes from suppliers too?
Yes. The same approach works for comparing several PDF quotes from suppliers. Your procurement team still reviews and decides.
