AI bid packages and ITBs for commercial contractors
Beginner
What is Downtobid?
Downtobid is AI bidding software for commercial construction. GCs upload a plan set, let AI detect trade packages and draft scope notes, then send personalised invitations from their own email. Subcontractors get a Bid Board for invites, deadlines and RFIs, plus free planroom access.
Downtobid is bidding software for commercial construction, built around two audiences that trade invitations all day: general contractors assembling bid packages, and subcontractors deciding which invitations deserve an estimator's time. The pitch is narrower than a full project management suite, and deliberately so. It targets the invitation to bid, the coverage list, and the deadline, rather than the whole build. For GCs, the workflow starts with a PDF plan set. The AI reads the sheets, identifies trade scopes, groups them into packages, and drafts initial scope notes. A human reviews and edits before anything leaves the building. Invitations are then sent from the GC's own email domain with the sub's specific scope summary, relevant sheets, and company branding attached, rather than as a generic blast routed through a portal. A coverage view tracks who has opened, who is bidding, and who needs a nudge. Existing subcontractor lists can be imported by CSV, matched against Downtobid's database, enriched where details are missing, and de-duplicated. On the subcontractor side, the Bid Board puts invitations, due dates, and RFIs in one place with a calendar view. Estimating teams can assign work to individuals so two people do not price the same job. A contractor search lets subs find commercial GCs that buy their trade. The company reports that planroom access and bid submission are free for subs, with Bid Board as the paid upgrade. The homepage positions Downtobid as an alternative to BuildingConnected, iSqFt, PlanHub, SmartBid, BidMail, Pantera Tools and Procore, and publishes head to head comparisons against each. Teams already deep in a full construction management platform may find this a bidding specialist rather than a replacement; the case for switching rests on package setup speed, invitations that arrive from a known address, and per user pricing instead of revenue percentage.
How do you use Downtobid?
1Start a free trial account
Sign up from the free trial page to create the organisation account. GC and subcontractor roles see different starting screens, so confirm the right one for your trade.
2Upload a plan set for AI package detection
In the ITB tool, upload the PDF plan set. The AI reads each sheet, groups trade packages, and drafts scope notes for your review.
3Review scopes and send personalised ITBs
Edit the generated scopes, then issue invitations from your own email domain with the relevant sheets and scope summary attached to each trade.4Import your subcontractor list
Bring an existing sub list in as a CSV. Downtobid matches it to its database, fills in missing details, and flags duplicate contacts.5Track coverage and follow up
Use the coverage view to see who has opened the invite, who is preparing a bid, and who needs a nudge before the deadline.
6Subs: manage invites on the Bid Board
As a subcontractor, track invitations, deadlines, and RFIs in one board, assign estimators, and avoid two people pricing the same job.
Pros and cons
Pros
- AI package detection turns a PDF plan set into trade scopes and draft notes, with a human review step before anything is sentAI

- Subcontractors can submit bids and use planrooms free, with Bid Board as a paid upgrade for deadline and assignment trackingAI
- CSV import matches an existing sub list against the Downtobid database, fills gaps and flags duplicatesAI
Cons
- The product concentrates on bid invitations and coverage, so estimating, takeoff and project management after award sit outside its scopeAI
- Subcontractor value depends on GC adoption: a sub board is only useful if the GCs sending invites are on the platformAI
- Supplier profiles are matched automatically against Downtobid's database, and the homepage gives no detail on how accuracy is verifiedAI
