Technician using an Electronic Parts Catalog (EPC) on a computer to build a parts quote with detailed car diagrams and VIN lookup interface, Building a Parts Quote Using EPC.

In today’s highly competitive automobile, industrial and machinery industries, the accuracy of identification of parts is essential. It doesn’t matter if you’re a dealership, repair facility, or distributor; creating an efficient parts quotation will save time, cash, and avoid costly mistakes. The Electronic Parts Catalogue (EPC) plays a pivotal role in achieving this accuracy.

This article offers a comprehensive guide to building a parts quote using EPC that covers the entire process, starting with VIN search to the final quote generation. Learn how to use EPC best practices and answer frequently asked questions that will assist your workshop or business to get the most benefit from EPC systems.

What is an EPC (Electronic Parts Catalog)?

The Electronic Parts Catalogue (EPC) is a tool that uses digital technology to help users recognise the location, identify, and provide parts for certain automobiles or models of machinery. EPCs are extensively utilised by car producers, parts suppliers and workshops to guarantee accurate parts identification and speedier customer service.

Key Functions of an EPC:

  • VIN-based identification of parts for exact matching.
  • Diagrams with illustrations and expanded views for confirmation by visuals.
  • OEM part numbers for standardised referencing.
  • Prices and details on availability to make it easier to prepare a quote.
  • Integration with DMS or ERP systems to provide seamless order management.

Some of the most well-known EPC systems are Toyota EPC, Ford Microcat, Hyundai Mobis, Caterpillar SIS, and Mercedes-Benz EPC.

Why Use EPC for Building Parts Quotes?

Making a quote by hand is time-consuming and error-prone. The use of an EPC makes the whole process easier:

  1. Accuracy: EPCs eliminate guesswork by connecting each component to the specific number of VINs or models.
  2. Effectiveness: Search filters and diagrams help you find the exact parts.
  3. Professional Quotes: The EPC system can generate detailed quotes automatically that include descriptions of parts as well as prices and quantities.
  4. The Trust of the Customer: The accuracy of quotes can build trust and avoid disputes.
  5. Integration: EPCs can sync with software for managing inventory and billing to automate the availability of parts and cost updates.

Step-by-Step Guide to Building a Parts Quote Using EPC

Step 1: Log in to the EPC System

Begin by logging in to your EPC platform using your authorised credentials. Based on the model, it could be a web-based platform (like Toyota EPC Online) or a desktop-based application (like Nissan Fast).

Check that your access level permits the generation of quotations and pricing.

Step 2: Enter the vehicle Identification Number (VIN)

The VIN is an individual 17-character number for each vehicle. When you enter the VIN, it will narrow the search results to the specific make, model year, and configuration.

The benefits of VIN Search:

  • Removes any unnecessary parts.
  • It ensures compatibility with models specific to regions.
  • Reduces returns caused by parts that do not match.

If VIN isn’t available, you can search by hand using the model, engine or chassis numbers; however, the accuracy could be less.

Step 3: Browse through the Catalogue Sections

After VIN decoding, the EPC shows the car’s structure broken down into major categories, for example:

  • Transmission and Engine
  • Suspension and Steering
  • Electrical and Electronics
  • Components of the Body and Interior
  • Brakes and the Fuel System

Each section has an exploded diagram that shows how the components are connected. By clicking on an element, you can see the details of the part, such as its numbers, descriptions, and notes.

Step 4: Select the Parts to be Quoted

Look through diagrams or parts lists and add the needed parts to your list for the Quote. The majority of EPC systems come with the “Add to Quote” or “Add to Cart” button beside every item.

Pro Tips: Double-check part supersessions or replacements. EPCs typically display notes if a brand-new one has replaced an older part number.

Step 5: Review Prices and the Availability

Once you’ve made sure to select all components, after that, make sure to check for:

  • The price list or price of the dealer is dependent on the access level you have.
  • Stock availability occurs when it is linked to an inventory management system.
  • Coupons and markups for quotes from customers.

If it is integrated into your ERP, or DMS When integrated with your ERP or DMS EPC can retrieve real-time prices and adjust your totals automatically.

Step 6: Create the Quote

When you have completed your checklist:

  • Select “Generate Quote” or “Export Quote”.
  • Check all the details -the part number, the quantity, the price and the notes.
  • Add shipping costs or taxes. If applicable, add taxes and shipping costs.
  • Export the Quote as a PDF document or an Excel document.

Many EPC systems let you add your company’s logo as well as contact information to create a professional-looking presentation.

Step 7: Print or send the Quote

Then take the time to make sure to share the Quote with your customer or the internal team:

  • Send emails directly through the EPC interface.
  • Printing for physical records.
  • Make a backup copy of this within your ERP or CRM to be used for future follow-up.

This process ensures the smooth transition from quotation to the confirmation of orders and invoicing.

Best Practices for EPC-Based Parts Quoting

  1. Always verify the VIN: Do not rely solely on the visual inspection.
  2. Check for new part numbers: EPCs regularly update the number of parts that have been superseded.
  3. Use images within quote marks: It helps customers find the parts easily.
  4. Cross-Check with Bulletins of Service: Some components may have updated specifications.
  5. Update your Pricing Database: Make sure that your customers’ quotes are accurate. Quotations.
  6. Utilise EPC Integration: Sync with inventory or billing software to reduce time.

Common Mistakes to Avoid

  • Utilising vehicle models that are generic instead of the VIN search.
  • Notes on parts that are not considered or region-specific variations.
  • Inability to update discontinued or superseded components.
  • Do not verify the part number and the fitment prior to giving a quotation.

By avoiding these mistakes, you can ensure satisfaction for customers as well as operational efficiency.
