Accubid Classic, AutoBid Mechanical, AutoBid SheetMetal, FastDUCT, FastPIPE, TRA-SER, Estimation MEP — that's 7 separate products to do what MEPSub does in one.
This is what MEP estimating teams deal with today — from a real Reddit post
"I work for a commercial MEP subcontractor, and our estimating team currently uses Accubid Classic for Electrical, FastDuct for Mechanical, and FastPipe for Plumbing. We signed up for Autobid to get our Mechanical and Plumbing teams into the Trimble family, but apparently this initiative has not gotten off the ground because the tool doesn't work the way that our estimating head originally thought it did..."
"I am now looking at alternatives in an effort to have a single platform for our estimators to use, and am looking for recommendations. Ideally, the platform would enable us to build assemblies/tasks and schedules and also have real time material pricing."
Accubid for electrical, AutoBid or FastDUCT for mechanical, FastPIPE for plumbing. Different interfaces, different databases, different workflows.
Each Trimble product is priced separately. Add TRA-SER for pricing data. Multiply by users. Costs compound fast.
Accubid Classic is Windows desktop software. AutoBid requires installation. No mobile access. No field-friendly interface.
Each product has its own training requirements. Reviews consistently mention weeks of setup and training needed. Error messages are common.
What you need to buy to cover all three MEP trades with Trimble
Legacy. 42K items, 13K assemblies. Windows only.
Cloud version. Includes submittal mgmt & Supplier Xchange.
100K+ items. Spec-driven takeoff. Separate from electrical.
Often bundled in Essentials subscription.
By FastEST Inc. Separate vendor from Trimble.
By FastEST Inc. Integrates with FastPIPE.

We believe in honest comparisons — Trimble has real strengths
Accubid Classic has 42,000+ items and 13,000 assemblies. AutoBid Mechanical has 100,000+ items. Decades of industry data refined over time.
Trimble's on-screen takeoff with automatic fitting generation and symbol auto-count is best-in-class for quantity takeoff from drawings.
Many large MEP firms have used Accubid and AutoBid for decades. Deep institutional knowledge and customized databases.
2 million+ items from 650+ manufacturers with supplier-direct pricing. The deepest pricing database in the MEP industry.
What Trimble's 7 products combined still can't do
Electrical, mechanical, plumbing — one login, one database, one workflow. No more juggling Accubid + AutoBid + FastPIPE + FastDUCT.
Spec parsing, AI estimates, scope gaps, product alternatives, terms & conditions, SOW generator, document chat, assembly creator. Zero Trimble products have this.
13,000+ item costbook with BLS labor rates and FRED material indices — all included. No separate TRA-SER subscription needed.
Submittals + Estimates + RFIs + Change Orders + Purchase Orders + Invoicing + Contacts + Reports. Trimble covers estimating only.
~$1,430/yr for a complete platform vs $12,000–$25,000+ for Trimble's product stack. Same team, same trades, fraction of the cost.
100% cloud, mobile-first PWA, light/dark mode, works on any device. No Windows-only installers, no desktop dependencies.

What an MEP team estimating across all three trades actually pays
Switching doesn't have to be all-or-nothing
Sign up for MEPSub's free plan. Create your first project. Upload a spec book and let AI parse it. See the difference in minutes.
Use MEPSub alongside your Trimble tools for a few bids. Compare estimate accuracy, time savings, and team feedback.
Move submittals, then RFIs, then invoicing into MEPSub. Each module works independently — adopt at your pace.
When you're confident, cancel Trimble subscriptions one by one. Save $10,000+ per year while gaining AI capabilities.
One platform for all MEP trades. AI-powered. Pricing included. Free to start.
