In this article, we'll explore specifically the key differences between Trimble Accubid Classic/Accubid Pro and PataBid Quantify.

Understanding Trimble Estimating Software Solutions

Trimble offers a comprehensive portfolio of estimating software solutions designed to serve various segments of the construction industry. Beyond their flagship Accubid platform, Trimble estimating software includes solutions like Trimble Viewpoint for enterprise construction management, Trimble Connect for project collaboration, and various specialized tools for different trades and project scales. This ecosystem approach allows Trimble to serve contractors ranging from small electrical companies to large enterprise construction firms.

However, while Trimble estimating software has established market presence, many of these solutions were developed years ago and reflect older technological approaches. The Trimble software suite often requires multiple licenses, separate installations, and complex integrations to achieve full functionality. For contractors seeking modern, streamlined solutions, understanding the limitations of traditional Trimble estimating software becomes crucial when evaluating alternatives like PataBid Quantify.

Understanding Trimble Accubid Software

What is Trimble Accubid?

Trimble Accubid is a comprehensive software suite designed for electrical and mechanical estimating in the construction industry. Developed by Trimble, this Trimble estimating software provides tools for creating detailed and accurate cost estimates for construction projects. The Accubid software platform offers two main versions: Accubid Classic (desktop-based) and Accubid Anywhere (cloud-based), each targeting different contractor needs and technological preferences.

Key features of Trimble Accubid include:

• Database: Over 40,000 items and 9,500 assemblies

• Integration: Links with Trimble LiveCount and TRA-SER pricing

• Collaboration: Trimble Connect for team communication

• Functionality: Dynamic takeoffs and multi-level breakdowns

  
  

What is Accubid Classic?

Accubid Classic represents the original desktop-based version of Trimble's construction estimating platform, first launching in 1995. This Accubid software has earned a reputation for reliability and depth in the electrical contracting industry. Accubid Classic functions as a locally-installed solution that requires additional modules and subscriptions to access its full functionality, including LiveCount for graphical takeoff and TRA-SER for material pricing integration.

Step-by-Step Workflow Comparison: PataBid vs. Accubid

1. Drawing Upload and File Management

Trimble Accubid Classic Workflow: Users must open LiveCount separately and manually import PDF drawings, creating a fragmented workflow. File management is handled across several disconnected tools: Accubid Classic, LiveCount, TRA-SER, and ChangeOrder Pro—which can increase complexity and risk of error during the estimating process.

PataBid Quantify Workflow: With PataBid Quantify, users upload drawings directly into the cloud-based estimating interface, streamlining the process from the start. All bid documents, markups, and revisions are stored in one centralized location with unlimited digital storage. The platform consolidates the functionality of Accubid Classic, LiveCount, TRA-SER, and ChangeOrder Pro into a single, unified construction estimating platform.

2. Performing Electrical Takeoff

Accubid Classic Process: Electrical takeoff must be performed manually within LiveCount, and quantities are then sent back to the main estimate in Accubid Classic—as long as the link between the two platforms is maintained without disconnection.

PataBid Quantify Process: Quantify offers built-in graphical takeoff, enhanced with optional AI automation. Estimators can select a symbol once, and Quantify will automatically count all matching items across the drawing with an accuracy rate of 80%. This significantly reduces manual data entry and accelerates electrical takeoff by 40% or more.

3. Applying Labor and Material Pricing

Trimble Accubid Classic Pricing: Material pricing relies on a TRA-SER subscription, and quotes often need to be entered manually. The platform does not support real-time supplier pricing, which can delay or complicate the estimating process.

PataBid Quantify Pricing: Quantify is integrated with major national suppliers like Gescan and City Electric Supply for real-time material pricing. Estimators can compare prices, stage orders by phase, and avoid late-hour quote issues. Labor rates are pre-loaded and fully customizable for greater flexibility.

Fragmented Vs. Unified Platform

Trimble Accubid Classic functions within a fragmented ecosystem, where essential estimating features are delivered through separate add-on licenses. To complete a full estimating workflow, contractors must purchase LiveCount for graphical takeoff, TRA-SER (TradeService) for material pricing, and the ChangeOrder Pro module for change management capabilities. While Trimble Accubid Classic enables users to manually input pricing and leverage its built-in legacy items database to generate final job costs, incorporating graphical takeoff requires launching the LiveCount application and uploading project drawings independently. This multi-application setup can add complexity to the estimating process. Additionally, the lack of seamless integration between Accubid Classic and LiveCount may occasionally result in takeoff data not appearing in the final estimate.

In contrast, PataBid Quantify is a fully integrated, all-in-one construction estimating platform solution. With a single subscription at one price, contractors gain access to a seamless platform that includes graphical takeoff, supplier pricing, built-in change order management, and more — ensuring accuracy, efficiency, and reliability in every estimate. Users can log in, upload any PDF drawing into Quantify, and easily navigate through the entire estimating process, from takeoff to summary and closeout. Quantify consolidates the functionality of Accubid Classic, LiveCount, TRA-SER, and ChangeOrder Pro into one unified platform. Our comprehensive database includes over 60,000 items, featuring modern LED fixtures, EV chargers, solar and more. To keep up with the evolving electrical industry, our data entry team continuously expands and updates the database to meet the latest contractor needs.

Locally Installed Vs. Cloud Native

Trimble Accubid Classic requires local installation on specific computers. If contractors have also purchased additional modules like LiveCount, TRA-SER, or ChangeOrder Pro, each of these must be installed separately also. Locally installed estimating platforms, like Accubid Classic, come with several major drawbacks. Access is limited to a single device, restricting remote work and real-time collaboration. Additionally, users bear the full responsibility of data security — meaning that file corruption, hardware failure, or accidental deletion could result in significant data loss. Manual backups are required, adding extra effort and risk. Software updates and bug fixes must also be manually installed, which can lead to compatibility issues with newer operating systems. On top of these challenges, Accubid Classic and its related programs require a USB HASP (Hardware Against Software Piracy) key for license management. The Accubid software will only function when this Accubid USB security key is plugged into the computer. If the key is lost, damaged, or stops working, there is currently no replacement option — rendering the software completely unusable. The USB HASP is also referred to by users as an Accubid dongle.

In contrast, cloud-native solutions like PataBid Quantify offer seamless access from anywhere, enabling estimators to work remotely without being tied to a specific device. No USB keys or dongles are needed — just a laptop or desktop and a stable internet connection to log in. With automatic data backups and secure storage, Quantify ensures that your estimates are never lost due to system crashes or hardware failures. Cloud-native platforms also benefit from continuous updates and improvements, eliminating the need for manual software upgrades. This ensures that users always have the latest digital tools for estimating at the lowest total cost of ownership. Hosted in a secure North American data center, all user data in Quantify is backed up daily to an additional system, providing peace of mind. By removing the risks and inefficiencies associated with local installations, Quantify delivers a more convenient, reliable, and scalable estimating solution for electrical contractors.

Building Assemblies and Item Libraries

Accubid Software Libraries: Although Trimble Accubid includes a comprehensive MEP items database with over 40,000 items and 9,500 assemblies, it does not include modern items that electrical contractors use on everyday projects.
