Building a startup takes time, effort, and a lot of determination. You and your team have invested in a great idea, and everyone works diligently to bring new team members, investors, and customers on board. However, the process doesn’t end once the product or service has taken off and gained popularity.
A startup can operate on a lean team, with people wearing multiple hats and taking on extra responsibilities. But as the company grows, it will be time to hire more employees and scale the company to meet demand.
How to scale the business is an enormous question that causes hesitation for many leaders. How do you expand your business offerings and your team without losing the heart and inspiration that helped the startup succeed in the first place?
In my own business, Tekmetric, which offers shop management software for auto repair businesses, I have relied on a few tactics that enabled me—and our whole team—to scale sustainably. Here are four of the most vital.
Understand Your Company’s History
To plan for the future, it’s crucial to have a deep understanding of the past. In Tekmetric’s early days, my five-person team and I were focused on creating a reliable technology—we didn’t necessarily think about the entity we were building along with it. However, our problem solving and determination to succeed would form the foundation of Tekmetric’s identity today.
The journey wasn’t easy. We faced challenges familiar to many startups: lack of interest, the need for financial support, and an imperative to attract the best talent around. We also had a lot to learn about software and how it applied in the automotive industry. In fact, that lack of software knowledge was an enormous setback, and there were times we just wanted to give up.
However, our failures in these early days were extremely important to our later success. Instead of giving up, the team faced our challenges head-on. We developed a new prototype of our product, established procedures to promote customer success, and created a clear structure within the company. And when the time came to grow, we hired talented people who shared our same drive and desire for success.
Those early days resulted in values that still permeate the Tekmetric culture today. When considering your own company, pinpoint your team’s top qualities and trace them back to the beginning. There are several key questions to answer:
What defines your company’s essential identity?
What challenges did you face and how did you overcome them?
What culture have you built—and how can you hire talent that helps preserve that culture over time?
Set Realistic Goals for the Future
Understanding your company’s past allows you to set realistic goals for the future. When setting these goals, it’s important to consider industry standards and your team’s abilities and limitations. To be realistic, your goals must allow you to keep up with industry changes, but they must also align with your team’s capability to succeed.
For example, if you work in the technology industry, you will need to set goals on a shorter timeline so you can keep up with new innovations and quickly changing needs, but you will also need to keep in mind your team’s current skills and limitations.
When Tekmetric sets a goal for monthly sales, we look at each team’s capacity to succeed. The customer success team may have a limited number of shops it can onboard each day, or we may need to account for migration time when transferring data. After identifying the limitations, we can then explore potential solutions that bring us closer to achieving our goals, such as investing in new technology or hiring more customer success team members.
Lean on Your Employees
As the company grows, it becomes more and more difficult for leaders to have a deep knowledge of every facet of the business. As much as you might want to know about—and maybe even control—every little thing going on within the company, there is only so much time in the day and so many places you can be at once. Your growing responsibilities as a leader mean you will be interacting with customers less and focusing more on the overall business.
However, you do have one key resource you will need to rely on more than ever: your team.
Your employees are the magic behind the work your company does each day. They make it possible for your product or service to work seamlessly, and they create successful interactions with customers.
Empower your team to share ideas and shed light on the changes that will be necessary to meet the goals you have established. As your arms and legs, they have intimate knowledge of the company’s abilities and limitations.
By trusting, empowering, and relying on your team, you enable the business to grow—and give them personal investment in the business’s success.
Continue to Grow Personally as a Leader
Finally, you must continue to invest in your own professional growth as your company grows and scales. You are the face of the company, both internally and externally. Your continued growth will allow you to expand your own perspective and learn new techniques to be an effective leader within the company.
Personally, I challenge myself to read at least one leadership book each week. Many of these books have similar messages, and by continuing to read those messages over and over again, they become firmly planted in my brain and daily practices.
I also seek professional coaching through CEO peer groups and business mentors; these offer outside perspectives that help me work through challenges and questions that come up as Tekmetric grows.
Patience is a Virtue
It takes time, energy, and patience to grow a company. At Tekmetric, we recognize that while we’ve had a tremendous amount of success in what feels like a short time, even that didn’t happen overnight.
As you work toward your own company’s growth, don’t lose sight of the excitement and passion that inspired the company’s initial foundation. Set realistic goals and build a team you can trust and rely on. And continue to grow as a leader in your own right.
Scaling doesn’t happen overnight. But with the same hard work and determination that made the startup successful in the first place, you have the potential to grow your company and make even greater achievements in the future.

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.
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

3. Date of service and invoice number
Every mechanic receipt needs to include the date of service and a unique invoice number. This creates an accurate timeline and helps organize documents chronologically for tax reporting, audits, or warranty purposes.
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.
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:

In the ever-evolving automotive industry, staying ahead of the curve means constantly learning and growing. For automotive service technicians, certifications aren’t just credentials—they’re powerful tools that open doors to better job opportunities, increased pay, and credibility with customers and employers alike.
Whether you're just starting out or already working in auto repair, understanding the most common types of mechanic certification can help you create a successful, long-lasting career. This guide will break down the most recognized certifications, how to attain them, and why they matter for every auto mechanic who wants to stand out.
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
Electrical/Electronic Systems
Engine Performance
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.
