ArosBid is a Trimble AutoBid alternative.

What we replace

ArosBid includes takeoff and estimate and replaces Trimble AutoBid.

STACK, McCormick, and FastEST are other takeoff tools in the market. This page does not claim them.

What AutoBid is built for

Trimble AutoBid is takeoff and estimating software used on mechanical and similar trade desks. Quantities and the estimate live there. That is a scope fact, not a defect list.

What ArosBid is built for

ArosBid includes takeoff and estimate. It also runs the process that starts when the invitation lands and ends when you submit:

• Intake recognizes the ITB and opens the pursuit.
• Tender review cites dates, conflicts, LDs, and alternates to page.
• Bid/no-bid is scored against your own GC history.
• Vendor RFQs go out as packages, with follow-ups, after a recorded approval during training.
• Leveling reconciles every total and lifts exclusions out of the fine print.
• Budget lands in Excel. The proposal is assembled from decisions you actually made.
• Readiness checks bonding, addenda, and gates before you submit.

Walk the stages on the platform page. The process comparison against a manual desk is on Compare.

Honest compare

• Takeoff and estimate. AutoBid is built for this. ArosBid includes it and replaces AutoBid.
• The bid after. Intake, tender review, bid/no-bid, vendor RFQs, leveling, proposal, readiness. That cycle is the rest of ArosBid. It is not what AutoBid is sold as.
• Money. Every extension, sum, reconciliation, and allowance in ArosBid uses deterministic integer-cent code. No model prices the job.
• Deployment. Each customer gets an isolated instance, own database and document store, own subdomain, Microsoft Entra ID.
• Send authority. During training, nothing leaves without a recorded human approval. It learns those decisions, then automates what you already signed off.

What this page will not invent

No customer names. No savings percentages. No AutoBid defect list we cannot cite. If a takeoff screen is not documented on this site, it is not described here. The claim is the product includes takeoff and estimate. The walkthrough is the proof.
