In today’s auto repair industry, data can play a key role in a shop’s ability to repair a vehicle more efficiently and accurately. Traditionally, repair information was documented informally, often by hand on paper. Today, this information can be captured and processed electronically, leading to a significant acceleration of the repair process – and a more positive customer experience

The transformative power of data extends beyond streamlining individual repairs. In fact, by strategically analyzing your shop’s data over time, you can also use the information to grow your shop. However, to maximize the impact of data, it’s important to know what kind of data is most effective to use in your shop. Some of the more evergreen data – performance over time – is useful in your long-term strategy, while others, such as real-time performance metrics, are more helpful in making short-term tweaks to promote better performance. In this blog, we’ll discuss how you can distinguish between evergreen and real-time data and where you can use both to grow your shop.

Understanding Real-Time vs. Evergreen Data

Before you can decide how to use data, it’s important to understand the difference between evergreen data and real-time data. Real-time data is live data that is available as soon as it is generated. It allows you to manage your shop and respond to situations instantaneously as they happen. On the other hand, evergreen data is used in hindsight, after a timeframe has ended. Most shops use this type of data to reflect after the repairs are complete.

Both forms of data have their uses. Real-time data allows you to respond to situations as they happen in a way that helps support your business. Evergreen data helps you track long-term trends and their effects on your shop. With Tekmetric, you can leverage both types to keep your shop running smoothly. When you leverage data strategically in all forms, you can optimize your shop’s operations and processes, create an excellent customer experience and prime your business for growth.

Stay Ahead of the Curve with Real-Time Data

Real-time data enables immediate visibility into what is happening with your shop at any given time. From inventory to customer communication to repair progress, you can review different buckets within your shop and respond as the day progresses. This capability allows you to make decisions on the fly without having to wait until the end of the day, week or month to know which parts need to be ordered or how many repairs you have completed. Strategically, real-time data can be used for short-term decisions that have long-term effects, ultimately becoming an integral piece to growing the shop’s bottom line.

Examples of how you can use real-time data might include:

  • Track daily progress with the shop dashboard:  Reviewing this in real-time allows you to respond to potential bottlenecks or problems that arise throughout the day. For example, if you see $15,000 in work pending approval before lunchtime, you can encourage your service writers to conduct follow-up calls to get approval and begin the work.
  • Send out rainy-day coupons: Business tends to slow down on rainy days. However, if you experience this, you can respond in real-time by sending a rainy-day coupon incentivizing customers to come in for quick-turn work, like oil changes. 
  • Monitor multiple shop locations with Tekmetric Multi-Shop: Multi-Shop can show you the performance of each shop at any time, from any location – so you can make decisions that support the strengths of all your locations. For example, you might move a car from a very busy, overrun location to another, slower location. Make sure you return the vehicle to the original location for easy customer pickup to maintain your customer experience. This maximizes workflow between high and low volume locations.

Analyze, Determine and Predict Trends with Evergreen Data

In addition to real-time data, you can leverage evergreen data by analyzing trends and your shop’s data for predictive forecasting. One of evergreen data’s biggest advantages is that it captures a period of time without the need for constant refreshing. This can help you review your shop’s performance over longer periods – year-over-year, month-to-month or quarterly – so you can implement long-term solutions to promote growth.

Examples of using evergreen data include:

  • Create more business with declined jobs: When you want to influence cash flow for the coming weeks or months, you can follow up on previously declined jobs, such as an oil change or tire rotation. This customer-centric approach can not only build your customer relationships, but also drive business during a slow month.
  • Create value with Shared Customer History: You can share your customer’s history across multiple locations, bringing extra value through this evergreen data. For example, if a customer asks when they had their last oil change, your service advisor will be able to pull that information within seconds – no matter which location the customer last visited.
  • Create custom financial reports to track shop performance: Tekmetric’s financial reports give you the power and flexibility to create a report that tracks what’s important to you, without any extra noise, and make decisions based on past performance. For example, you can utilize the Time Period Configuration feature to compare data from the previous year or another custom time period, identifying bottlenecks and adjusting your strategy accordingly.
  • Track month-over-month trends with comparative reporting: Pay attention to the trends that occur each month in comparison to the same time frame in previous years. This will allow you to spot trends and respond accordingly, such as preparing for a particularly busy season or implementing strategies to create more work in a slower season.

The Price of Ignoring Data

Time is money. Evergreen and real-time data allow you to manage your shop’s time and resources in the most efficient manner to generate profit while providing an excellent customer experience. To grow your shop, ensure you are using both forms of data to your advantage. Combining evergreen data’s longevity with real-time data can lead you to a multi-faceted business strategy, creating a customer-centric approach that ultimately generates more cash flow, profit and growth.

What Should Be Included in an auto repair shop receipt?

1. Shop contact information

The first thing on your receipt should be your auto repair shop’s full contact information. This builds credibility and ensures customers know how to reach you if follow-up is needed.

What to include:

  • Shop name
  • Address
  • Phone number
  • Email address
  • Website (if applicable)
  • Business logo for branding

A well-organized template with your logo and contact information at the top makes your documents look professional and trustworthy.

2. Customer Information

Next, capture the customer’s name and their contact information. This ensures the receipt is tied to the correct individual and helps with record-keeping for recurring car repair clients.

What to include:

  • Customer's name
  • Address
  • Phone number or email

What to include:

  • Date the service was completed
  • Unique invoice number
  • Optional: technician’s name or initials

4. Vehicle information

For any automotive service, tying the repair order to a specific vehicle is a must. This helps with real-time service tracking, vehicle history reporting, and future maintenance recommendations.

What to include:

  • Year, make, and model
  • Vehicle Identification Number (VIN)
  • License plate number
  • Mileage at the time of service

5. Description of services performed

This is the heart of the receipt. Clearly outline what repair work was done and what repair services were provided. The more detail, the better.

What to include:

  • Itemized list of services
  • Description of each job (e.g., “Brake pad replacement” or “Engine diagnostic”)
  • Associated labor costs for each service
  • Cost of parts

6. Parts and material breakdown

An itemized list of parts and materials used in the repair work is just as important as the labor section. This transparency helps avoid disputes and gives your customer clarity on what they’re paying for. Most auto repair shops don’t show the markup percentages on parts but you can if you want to maximize transparency.

What to include:

  • Part name and number
  • Quantity used
  • Cost per unit

7. Balance Due and Payment Summary

Now it’s time to outline the financials, from the subtotal to the total amount. This section should also include the total cost, taxes, discounts, and any payment options you accept.

What to include:

  • Subtotal (before tax)
  • Taxes (state/local)
  • Any discounts or promo codes
  • Total amount due
  • Payment methods accepted (e.g., cash, credit card, financing)
  • Amount paid and remaining balance
  • Due date for final payment, if applicable

Including this section with clear headings avoids confusion and can prevent billing issues down the line. It also ensures the receipt can function as proof of payment. Lastly, this is a great place to feature your financing options (if applicable).

8. Warranty Information

Warranty details protect both your shop and your customer in case a part fails or a job needs to be redone. If your auto repair shop offers any warranty, you need to clearly list what’s covered and for how long.

What to include:

  • Warranty length (e.g., 12 months or 12,000 miles)
  • What is and isn’t covered
  • Instructions for claiming the warranty
  • Any third-party coverage (for example, if a part manufacturer offers a separate warranty)

This section should be written in clear, non-technical language to help customers fully understand their protections. You may want to include a signature line for the customer to acknowledge receipt of the warranty.

9. Streamline receipts

Creating receipts and invoices by hand can be tedious but Tekmetric streamlines that for you. Tekmetric can help you build faster estimates and take payments digitally with our auto repair estimate software.

Some of our features include:

  • Streamlined estimate building
  • Digital approvals
  • Job history and reporting in one place

Image showing the various type of mechanic certifications.

Types of mechanic certifications

Mechanic certifications come in many forms, each tailored to different specializations and career goals. The most common types include:

1. ASE Certifications

Issued by the National Institute for Automotive Service Excellence (ASE), these certifications are the gold standard for automotive mechanics. They cover a wide range of specialties, from engine repair to electronic systems and air conditioning.

ASE certification is considered the most prestigious and widely accepted credential in the automotive world.

More about ASE

Founded in 1972, the National Institute for Automotive Service Excellence sets the benchmark for automotive service technicians. ASE offers over 50 different certification tests in categories like:

  • Engine Repair
  • Brake Systems
  • Air Conditioning and Heating
  • Suspension and Steering

  • Manual and Automatic Transmission/Transaxle
  • Light Truck and Diesel Engines

Master technicians

There’s also a separate path for master technician status, which is achieved by passing all certifications in the required testing areas for that series. For example, technicians certified in tests A1 through A8 are Master automobile technicians.

Master technician status is not for life. You must keep each one of those certifications current to maintain master technician status. If you lose master technician status due to the lapse of one or more required certifications, it can be reinstated by taking and passing the recertification tests.

How long does it take to become ASE certified?

To become ASE certified, expect to spend anywhere from 1–3 years, depending on your work experience and whether you’re currently enrolled in training programs. Each certification test typically takes 1 to 2 hours to complete and can be scheduled at a local test center.

Being ASE certified shows you’ve mastered the skills needed for the job. It’s a badge of excellence recognized by employers, repair shops, and even customers looking for reliable service.

2. Student certifications

Geared toward high school and post-secondary students in automotive technology programs, these ASE certifications offer a head start in proving foundational knowledge.

What are student certifications?

Student certifications validate entry-level knowledge in core areas of vehicle repair and maintenance. These don’t require work experience and serve as a stepping stone to full ASE status.

Programs approved by the ASE Education Foundation often include student certification exams as part of their curriculum. These are excellent options for students at auto mechanic schools or in a community college training program.

Student certifications are valid for two years and help you build confidence before entering the workforce as an entry-level technician.

3. Manufacturer certifications

These certifications are specific to vehicle manufacturers and offered by companies like Ford, Toyota, GM, and others. Often, auto technicians working in dealerships will pursue these to show mastery of brand-specific systems.

For repair technicians who want to specialize in a particular brand, manufacturer certifications are essential.

Manufacturer training programs

  • Toyota T-TEN
  • Ford ASSET
  • GM ASEP
  • Honda PACT
  • BMW STEP

These accredited programs often partner with dealerships to offer real-world, hands-on experience while you earn your credential. These programs can take anywhere from 12 to 24 months and typically require completion of automotive technology coursework alongside on-the-job work experience at a brand-affiliated repair center.

Why they matter

Manufacturer-certified auto technicians often have a faster path to high-paying roles within dealership networks and brand-specific repair shops. These certifications also prepare you to service increasingly complex vehicle systems, especially as brands continue to innovate with hybrid and electric vehicles.

4. Specialty certifications

You’ll also find credentials related to diesel engines, heavy truck systems, collision repair, and even hybrid/electric vehicles.

Each of these certification types plays a unique role in an automotive technician’s career path, and in many cases, earning more than one will make you significantly more marketable in repair shops and beyond.

Depending on your interests, you may also want to pursue:

  • A/C Refrigerant Certification - Necessary if you want to be able to to buy refrigerant and work on air conditioning service.
  • Diesel Mechanics Certification – Focused on diesel engines used in commercial fleets and heavy truck applications.
  • Collision Repair Certification – Great for auto mechanics looking to work in body shops.
  • Hybrid/Electric Vehicle Certification – A growing field with high demand.

Each of these certifications typically requires completion of a specialized training course and a passing score on certification exams. These programs may be part of a broader certificate program or offered as a standalone credential.

Tek-Tip: Another way to get ahead as a young technician is to be experienced with auto repair shop software so your employer doesn't have to teach you how to use their system.

Benefits of mechanic certifications

Getting certified is one of the most direct ways to turn your hands-on experience into a long-term career asset. Mechanic certifications do more than look good on a resume—they deliver real-world advantages. Here are some of the benefits of completing automotive certifications:

  • Increased Pay: Certified mechanics typically earn higher wages. According to the Bureau of Labor Statistics (BLS), certified automotive mechanics can earn higher hourly rates, especially in competitive markets.
  • Job Security: The more certifications you have, the more valuable you are to auto repair businesses.
  • Professional Credibility: Certification demonstrates a commitment to quality and standards, building trust with customers and employers.
  • Career Advancement: Certified automotive service technicians are more likely to advance to roles such as shop foreman, master technician, or service manager.
  • Mobility: Certifications make it easier to move between different types of employers—whether that’s independent repair shops, starting a mobile mechanic business, dealerships, or specialty service centers.

What does the certification process look like?

Most mechanic certifications follow a similar pathway but always refer to the specific instructions for your program.

Step 1: Enroll

Start by enrolling in an automotive technology program. These are offered by community colleges, trade schools, and accredited auto mechanic schools. Many programs are supported by the ASE Education Foundation, ensuring alignment with real-world industry standards.

Look for certificate programs or associate degrees that offer hands-on training. Financial aid is often available for eligible students.

Step 2: Gain work experience

Work experience is critical for most certifications. For ASE certification, for example, you need at least two years of on-the-job experience—or one year plus a diploma from an accredited program. You’ll need to show that you’ve worked on everything from brake systems and axles to manual drive train repairs and electrical systems.

Step 3: Pass certification tests

Most mechanic certifications require passing written or computer-based certification exams. These are typically held at a certified test center. The exams cover a variety of topics depending on the specialty, including engine performance, electronic systems, and automatic transmission repair.

Tek-Tip: Some auto shops/employers will pay your test fees for you.

Step 4: Maintain certification

Many certifications require recertification every five years. Staying current ensures you’re up to date with the latest automotive repair techniques, tools, and systems.

Final thoughts

Becoming a certified mechanic takes dedication, but the payoff is worth it. From better job prospects to increased credibility, mechanic certifications help you build a successful, respected career in automotive repair.

Invest in your future. Get trained, get certified, and become a leader in the ever-growing world of automotive repair.
