Subcontractor bid management software

Send the same scope.Compare every bid.

Buildiante turns selected BOQ positions into a structured subcontractor bid package, gives bidders a consistent scope to price, and brings responses together for comparison and award.

Buildiante subcontractor tendering interface showing invited subcontractors, submitted bids, bid comparison, and awarded bidder

Same scope for every bidder

Start from selected BOQ positions so every subcontractor is pricing the same work.

Comparable responses

Bring submitted bids together instead of manually comparing differently formatted spreadsheets and documents.

Clear award decision

Keep the selected bidder and awarded amount connected to the project record.

The tendering problem

The hardest part of tendering is often comparing what comes back.

When every subcontractor receives a different document and returns pricing in a different format, your team spends more time normalizing bids than evaluating them.

Copy-paste BOQ rows into tender documents
Send separate emails to every subcontractor
Receive bids in different formats
Manually reconcile scope and pricing
Lose the connection between the original estimate and award
With Buildiante

Turn your priced scope into a controlled tender.

The tender starts with the work you have already priced. Each invited subcontractor receives the same defined scope, making the responses easier to compare and the award easier to track.

Select BOQ positions for the bid package
Invite multiple subcontractors to the same scope
Collect submitted bids in one place
Compare responses against a consistent scope
Record the awarded bidder and amount
How it works

From BOQ scope to subcontractor award.

Buildiante keeps the tender connected to the estimate so your team doesn't have to recreate the same scope every time work is sent out for pricing.

01

Select the scope

Start with the BOQ positions you actually want subcontractors to price instead of rebuilding the scope in another document.

02

Invite bidders

Send each subcontractor a scoped bid package through a controlled link with the same line items and requirements.

03

Compare responses

Bring submitted bids together so pricing can be compared against the same scope instead of reconciling different documents.

04

Award the work

Review the submissions, select the winning bid, and keep the award connected to the project record.

Compare with confidence

One scope. Multiple bids. One decision.

The value isn't simply collecting bids. It's making sure the bids you receive can actually be compared.

What's included

Everything you need to run a controlled tender.

Select a subset of BOQ sections and positions to package into a bid.
Invite subcontractors by email — they get a scoped, expiring link, no account needed.
Compare submitted bids side by side before awarding.
Awarding creates a subcontract record linked to the winning bid.
Bid packages come directly from the BOQ you already priced. Once awarded, the subcontractor relationship becomes part of the project workflow your field team tracks against.
Who it's for

Built for teams managing subcontractor packages.

PMs and estimators who currently assemble a bid package by copying line items into a new document, email it to a handful of subcontractors, and then reconcile whatever comes back — PDFs, spreadsheets, phone quotes — into one comparison by hand.

Replaces

Move away from email-driven tendering.

An email thread with attached spreadsheets per subcontractor, and a manually built comparison sheet that has to be rebuilt every time a bid comes in late or gets revised.

Tender feeds directly into the next step of the loop:
