EWC Multi-Unit: 5 Quality Lessons for 2026 Growth

When Sarah Chen decided to turn her single, wildly successful waxing studio into a multi-unit operation across Atlanta, she wanted to copy her exact standards. Her Buckhead spot was famous for its service quality and happy clients, people who came back again and again for the attention to detail. But scaling that very personal kind of excellence across several new sites, each with its own staff and quirks, was a huge task. Opening more doors was the easy part. The hard part was making sure every door led to the same great experience. Growing a multi-unit business, especially in the beauty industry, really teaches you some hard lessons about quality control. So how does a business like Sarah’s grow without watering down what made it a success in the first place?

Sarah’s first move was to expand fast. In 18 months, she opened three more studios: one in Midtown, one near Perimeter Mall, and a fourth in Alpharetta. Aesthetically, they were all clones of the original, with the same calming decor and the same premium, gentle hard wax products. But the client feedback, which was always glowing for Buckhead, started to show some cracks at the new locations. I’d see comments like, “The Midtown location is good, but not quite the same,” or “I had a great experience in Buckhead, but less so in Alpharetta” popping up in her reviews and direct messages. It wasn’t a total disaster, but it was a clear sign that the quality she was so proud of was getting diluted.

Sarah quickly figured out the problem wasn’t the product or the decor. It was the execution. The training for her new staff, which she thought was thorough, didn’t have the nitty-gritty detail and constant reinforcement needed to really bake in her original studio’s service philosophy. She’d hired experienced estheticians and given them a standard manual, assuming the quality would just transfer over. It’s a mistake I see a lot of growing businesses make. A 2024 report by the National Retail Federation (NRF) put it plainly, saying that “consistent employee training and development are directly correlated with sustained brand perception, especially in service-oriented industries.”

Standardized Training and Certification

One of the first things Sarah did was completely tear down and rebuild her training program. She realized training had to be an ongoing process, not a one-time class. Her original program was two weeks. The new one was a full month for every new hire, no matter how much experience they had, and included a required annual refresher for all her current staff. This new curriculum, which she built with help from industry consultants, was all about hands-on practice and role-playing client interactions. For instance, every esthetician now had to prove they could flawlessly perform at least five different waxing techniques with her specific, approved products before they ever touched a client. The focus shifted from just knowing the steps to executing them perfectly, every single time.

A huge part of the new training was a formal certification process. Estheticians had to pass both written and practical exams to get certified to work in her studios. This covered way more than just technical skill. It included client communication scripts, aftercare recommendations, and the exact words to use when talking about services. Sarah knew the client experience starts the second they walk in and doesn’t end when they leave. “We needed to ensure that every interaction, from booking to aftercare, felt cohesive and professional,” she told her managers in a quarterly meeting. From my experience, it’s that level of obsessive detail that separates a good service business from a truly great one.

Strong Quality Assurance Protocols

After fixing training, Sarah knew she needed a system for monitoring quality. She created a dedicated Quality Assurance (QA) team of two of her most experienced managers. Their only job was to conduct regular, unannounced audits at all the studios. The audits were intense, covering everything from how clean the waiting room was to the esthetician’s precise application technique. They worked off a detailed checklist that scored every part of the client’s journey, including appointment timing, how products were being used, and if sanitation rules were being followed. The point was to find systemic gaps and offer real feedback, not just to catch people messing up.

The QA team also sent in mystery shoppers. These were people hired to act like regular clients, and they gave priceless, unbiased feedback on the whole experience. Their reports often caught subtle things internal staff would miss. For example, one shopper reported that the waxer at the Perimeter Mall location was amazing, but the front desk staff seemed rushed and unwelcoming compared to the team in Buckhead. This specific feedback let Sarah target retraining or tweak operations at that one studio, instead of making big, sweeping changes that wouldn’t have worked. A 2025 study from the American Society for Quality (ASQ) confirmed this, stating that “proactive, data-driven quality assurance programs are critical for maintaining brand integrity during periods of rapid growth.”

Centralized Feedback for Continuous Improvement

To really get inside her clients’ heads, Sarah set up a centralized feedback system. After every appointment, clients got an email or text asking them to rate their experience and leave comments. All that data poured into a single dashboard where she and her managers could see satisfaction scores broken down by location, by esthetician, and over time. This real-time feedback loop was incredibly effective. Instead of waiting for a problem to blow up into a bunch of bad online reviews, her team could spot a concern and fix it almost immediately.

For instance, when the Alpharetta studio’s ratings dipped because of “wait times,” Sarah was able to pull up the data, look at the scheduling patterns for that specific week, and adjust her staffing levels for peak hours. This created a culture of continuous improvement, it wasn’t just about putting out fires. Each studio’s team had regular meetings where they reviewed their own feedback data, which made them take ownership of their quality scores. It became a collaborative process, not a top-down order. The transparency even sparked some healthy competition between the studios to get the best client satisfaction scores, which pushed the quality up for everyone.

Operational Manuals: Non-Negotiable Guides

Maybe the most foundational thing Sarah locked down was the creation of complete, non-negotiable operational manuals. These were living documents, available digitally to every employee through a secure internal website, not some dusty binder on a shelf. Every single process, from how to sanitize tools to the exact, minute-by-minute steps for a Brazilian wax, was documented. This got rid of any grey areas and gave every employee, old or new, a single source of truth for how things should be done.

The manuals had detailed guides on product usage, which made sure the premium hard wax was always used correctly to give the client the most comfortable experience with the least irritation. They also laid out exactly how to handle client complaints, manage appointments in their scheduling software (Mindbody), and keep the studio looking perfect. These manuals were the bedrock of her entire system, for training, for audits, and for daily work. I’ve seen so many businesses fail at scaling because they rely on word-of-mouth knowledge instead of writing their processes down. Without that explicit documentation, quality just becomes subjective and you get a different result from every team.

Technology’s Role in Scaling Quality

Sarah also made some smart tech investments to hold her multi-unit strategy together. On top of the feedback system, she upgraded her client relationship management (CRM) software and rolled it out across all locations. This meant any studio could see a client’s entire history, their preferences, and notes from past services, giving them a personal experience no matter which location they chose. If a client preferred a certain aftercare product or even liked the room a specific temperature, the esthetician knew it before they even walked in.

She also added an advanced inventory management system that was tied into her point-of-sale (POS). This made sure all locations had the right products on hand and prevented stockouts that could kill the client experience. For example, the system would automatically place an order for her specialized soothing serums when inventory at any location fell below a set level. These tech investments were expensive upfront, but they paid for themselves by keeping operations efficient and consistent, which clients perceive as quality. It’s no surprise that the 2026 “Future of Retail” report by Forrester Research (Forrester) pointed to integrated tech platforms as being essential for any multi-location business that wants to scale a high-quality customer experience.

By weaving together all these strategies, tough training, proactive QA, a constant feedback loop, detailed manuals, and smart tech, Sarah Chen turned her expansion into a true success. Her growth was about expanding her brand’s promise of consistent, top-tier service, not just adding more pins to the map. The early complaints about inconsistency disappeared, replaced by glowing reviews that praised the professionalism and quality across all her Atlanta studios, from busy Midtown to suburban Alpharetta.

The lesson from Sarah’s journey is pretty clear for any business owner looking to expand, especially in a service industry: you can’t just hope for quality. You have to design it, build it, and protect it every day. It takes real effort, strong systems, and an obsessive focus on the little details that make up the client experience. Without those pieces in place, growth can easily become a liability that tears down the very reputation you worked so hard to build.

The success of a multi-unit strategy depends on an unwavering commitment to replicating and improving the core quality that defines the brand, which makes deliberate investments in training, systems, and feedback loops the key to sustainable growth.
