Decoding the quoting puzzle: how automation transforms wire harness manufacturing

Jan 22, 2025

The uphill battle of quoting from PDFs

How often do you find yourself staring at an incomplete OEM design file, wondering where to even begin? A vague PDF with missing quantities, ambiguous part numbers, and an abundance of "as required" notes is more common than you'd think. For wire harness contract manufacturers, this is the daily grind—and it's exhausting.

But have you ever paused to ask: What if there was a better way? What if you could reduce the hours spent deciphering messy files? Or free your team to focus on innovation instead of manual interpretation? Most importantly, what if accuracy in quoting became the rule rather than the exception?

Let’s step back, shift perspectives, and explore how automation can redefine this process.

Shift 1: The input problem—when a BOM is just the beginning

Picture this: you receive a PDF from an OEM. It contains a rough sketch, an incomplete bill of materials (BOM), and cryptic notes like "as required." There’s no CAD file to work from and little standardization. Now it’s your job to turn this into a precise quote. How?

For many manufacturers, the answer involves hours of tedious cross-referencing. Engineers painstakingly convert internal part numbers into real-world components, estimate quantities, and navigate unique formats for each OEM. Even with the best team in place, the process is error-prone and inefficient.

What’s worse, every OEM does things differently. Some offer reasonably complete details, while others provide BOMs that feel more like puzzles. Each guess introduces risk: inaccurate material quotes, inflated labor costs, and delays that could cost you a contract.

Shift 2: The human cost—when quoting bottlenecks your team

It’s not just the files that present challenges—it’s the burden they place on your team. The task of quoting often falls to the most skilled engineers because of the complexity involved. One manufacturer noted that their plant’s general manager is the only one trusted to quote labor hours, leaving them overwhelmed with simultaneous responsibilities.

In fact, many manufacturers handle hundreds—or even thousands—of quotes at any given time. With so many requests and such incomplete data, lead times suffer, and accuracy takes a hit. The result? Missed opportunities, strained resources, and a reduced ability to compete effectively in the market.

Now, let’s imagine a different future. What if you could upload those messy PDFs into a system that reads, interprets, and enriches them for you? Automation can do just that, turning a frustrating process into an opportunity for growth. Here’s how:

  1. Understanding the design: The system scans the PDF to identify gaps like “as required” and suggests solutions from a comprehensive component library. It flags missing information for review, minimizing guesswork.

  2. Enriching the BOM: Automation fills in missing part numbers, quantities, and real-time pricing using supplier data and your approved vendor lists. This ensures both accuracy and cost optimization.

  3. Streamlined quoting: The enriched BOM powers an automated request-for-quote (RFQ) process. Gaps are filled using web crawling, suppliers are contacted, and results are seamlessly backfilled—all without manual intervention.

This means faster turnaround times, better resource allocation, and quotes that are both competitive and precise. Skilled engineers can focus on solving higher-value problems, while your quoting process transforms from a bottleneck to a competitive advantage.

Competitors: valuable solutions with room for growth

Several tools and platforms already support aspects of the quoting process, each bringing unique strengths to the table. While they excel in specific areas, the challenges of wire harness manufacturing require a tailored approach. Here’s a breakdown:

CAD Tools (e.g., Zuken, Capital)

  • Strengths: CAD tools are fantastic for industries like PCBAs, where CAD models are the norm. They provide robust design capabilities and can integrate well with standardized workflows.

  • Drawbacks for wire harnesses: Most wire harness manufacturers work from PDFs, not CAD files. Rebuilding designs in CAD is labor-intensive and impractical when quoting hundreds of projects simultaneously. Additionally, these tools lack real-time pricing and labor estimation, making them less suitable for the unique needs of this niche.

Component Aggregators (e.g., Octopart)

  • Strengths: Aggregators shine at providing real-time component availability and pricing. They connect you with a wide network of suppliers, giving you visibility into the market.

  • Drawbacks for wire harnesses: While effective for simple BOMs, aggregators don’t handle complex, incomplete data well. They also can’t account for approved vendor lists, special pricing agreements, or the unique labor demands of wire harness manufacturing.

Specialized Quoting Tools (e.g., solutions for PCBAs)

  • Strengths: These tools streamline quoting for PCB assembly by integrating design, pricing, and availability data into a single platform. They’re ideal for manufacturers with standardized BOMs.

  • Drawbacks for wire harnesses: Wire harness projects often involve variable wire lengths, splices, and connectors, adding layers of complexity that these tools aren’t designed to handle. While effective for PCBs, they lack the customization needed for wire harness manufacturers.

Each of these tools contributes valuable insights and capabilities. However, their limitations underscore the need for a solution built specifically for wire harness quoting—one that combines real-time data, automation, and flexibility to meet the industry’s unique challenges.

An integrated future

Automation isn’t just a nice-to-have; it’s the key to unlocking new potential in wire harness manufacturing. By eliminating inefficiencies, reducing errors, and empowering your team, automation transforms quoting from a resource drain to a strategic advantage.

But the journey doesn’t stop with materials. Labor quoting, often an even bigger challenge, is the next frontier. By leveraging data and automation, manufacturers can bring consistency and accuracy to labor estimates, creating a truly end-to-end quoting solution.

So, ask yourself: How much time and energy are you losing to inefficiencies? What could your team accomplish with a streamlined process? And how will your business evolve when quoting becomes a strength, not a struggle?

Now is the time to act. Automation isn’t just the future—it’s already here. Are you ready to embrace it?
