Why Big Brands Choose Shopify Plus

Growing online stores need more than just a basic website. They need a platform that can handle lots of sales, complex operations, and deliver great shopping experiences. That’s where Shopify Plus comes in.

Shopify Plus powers some of the biggest brands you know. Let’s look at why it matters if you’re outgrowing your current store.

Handles Big Sales Without Crashing

Ever tried to buy something during a flash sale only to find the website crashed? Shopify Plus prevents that headache. It can process up to 10,978 checkouts per minute without slowing down.

This means you can focus on growing your business instead of worrying about your site crashing when things get busy. As Frederick from Karen Finch puts it:

“We were looking for someone who could work with all the challenges in our existing setup and do the best with what we had.”

Custom Checkout Pages That Sell More

One of the biggest perks of Shopify Plus is that you can completely customize your checkout pages. Regular Shopify doesn’t let you do this.

With Shopify Plus, you can:
– Match your checkout to your brand’s look
– Add custom fields to collect useful information
– Include trust badges to make customers feel secure
– Test different versions to see what sells better

According to Shopify, a better checkout can boost sales by 20-30%!

Automation That Saves Time

Running a big online store means doing lots of repetitive tasks. Shopify Plus has tools that handle these tasks automatically.

Shopify Flow: Your Digital Assistant

This tool lets you set up “if this, then that” rules for your store. For example, it can:
– Tag your best customers for special treatment
– Send alerts when inventory gets low
– Flag potentially fraudulent orders

Launchpad: Run Sales While You Sleep

When you launch a new product or run a sale, Launchpad can handle it all automatically:
– Make products visible at the right time
– Change prices when the sale starts
– Switch back when it ends

No more staying up until midnight to launch your Black Friday sale!

Connect With Your Other Business Tools

Shopify Plus works better with other business software thanks to its powerful connection options. This means your inventory system, customer service tools, and marketing platforms can all talk to each other.

Liz from Mixology appreciated this flexibility:

“I like that they gave us different options to fix our problems. They explained everything clearly so we could choose the best solution.”

Sell to Both Businesses and Consumers

If you sell to other businesses as well as regular customers, Shopify Plus makes it easy with:
– Special pricing for different customers
– Minimum order requirements
– Payment terms for business customers
– Company account management

This means you don’t need two separate websites for B2B and B2C sales.

Manage Multiple Stores in Different Countries

Want to sell internationally? Shopify Plus lets you run up to 10 different stores from one dashboard. Each can have:
– Local currencies
– Translated content
– Different pricing
– Country-specific shipping rules

This helps you create stores that feel local to each market you serve.

Finding the Right Shopify Plus Developer

Having Shopify Plus is great, but you need experts to get the most from it. A good Shopify Plus developer like Ecommerce Partners can help you use all these features effectively.

When choosing a developer, look for:
– Shopify Plus certification
– Technical know-how
– Understanding of your business goals
– Examples of successful projects
– Ongoing support options

Becky from QC Supply explains why having the right partner matters:

“They were a great thought partner for me and helped keep our project organized and moving forward. That was super valuable.”

Real Success Stories

Brands using Shopify Plus have seen amazing results:

Fire Dept. Coffee increased revenue 4X after upgrading to Shopify Plus.

LSKD grew US sales by 216% in one year using Shopify Plus’s international tools.

Is Shopify Plus Right for You?

Shopify Plus works best for businesses that:
– Make over $1 million in annual sales
– Experience busy shopping periods
– Need custom features standard Shopify doesn’t have
– Sell internationally or through multiple channels
– Have complex business requirements

For businesses at this level, the investment in Shopify Plus typically pays off quickly through increased sales and lower transaction fees.

Taking the Next Step

Shopify Plus gives growing brands powerful tools without the technical headaches of traditional enterprise systems. The right developer can help you create amazing shopping experiences while making your operations more efficient.

If you’re ready to take your online store to the next level, partner with experienced Shopify Plus developers who can help you make the most of the platform.

The Challenge

Chantecaille is a skincare brand specializing in natural beauty products, powered by high concentrations of pure botanicals and soothing, plant-based ingredient that is exploding in popularity and needed a solution to keep up with growing demand not just in the US, but worldwide. This solution needed to take into account the needs of each market, including language, price, currency, product selection and local marketing. In addition, the site had to be optimized for Google Pagespeed and ADA compliant. and online sales.

What We Did

Ecommerce Partners built multiple stores for their worldwide presence in the US, UK, Taiwan, Hong Kong and South Korea.

  • Completely customized design with editable style elements including homepage and top navigation.

  • Optimized for Google Pagespeed

    • Mobile Pagespeed score increased from 12 to 56

    • Desktop Pagespeed score increased from 11 to 92

  • ADA remediation

  • Streamlined product page with video, ingredients and enhanced product content

  • ERP integration

  • Shopping Gives integration

  • Full google analytics integration

  • Custom product badges

  • Shipping customizations

  • Klaviyo integration including back in stock and coming soon flows

  • Mini cart coded in speed optimized JS

  • Tableau integration

  • Yotpo loyalty and reviews integration

  • User checkout and login phone authentication

  • Language translation

  • LMS loyalty integration

Ecommerce Partners also provides monthly support and maintenance through their customer support team. We are always looking at Shopify’s newest technology and how it can be added into the Chantecaille website to enhance user experience and streamline backend services.

The Impact

  • 50% Growth in Online Sales: The new digital strategy drove more users to their website.

  • 10K New Followers: Instagram gained a loyal audience.

  • Loyalty Boost: Introduced a membership program, converting 40% of first-time buyers into repeat customers.

Background

QC Supply provides products and services to farmers and homesteaders across the United States for over 40 years. Their current ecommerce platform was based on Magento and had many problems. Their Magento website was based on an aging platform and they needed a modern solution. QC Supply approached Ecommerce Partners after one of their partners, Network Doctors, a top managed IT support company, referred them to find a solution that will modernize their website and set them up for the next 40 years.

Problems:

  • Magento ongoing maintenance was very costly
  • Making simple changes to the site took a long tim to complete
  • Code deployment involved a manual process and disabled the site for hours at a time
  • Pagespeed was slow (33/36)
  • Website lacked auto-scaling for high demand periods
  • Load balancing was not working properly
  • No standby or backup systems in case of failure
  • Frontend security issues existed which made the site vulnerable to attack
  • ERP integration was not efficient. Products had to manually be entered into Magento and many updates were not automated.
  • Database and PHP version were out of date

Solution

ECP’s first task was to gather all requirements for QC’s website business in order to recommend a platform that will work best for them. They conducted extensive interviews with each department to make sure that all stakeholders were taken into account when making their recommendation. There were many requirements to take into account, including heavily customized ERP integrations, ease of use, user and staff permissions, scalability, security, comprehensive API needs, website speed, complicated shipping quoting, complex tax and extensive B2B functionality.

Ecommerce Partners recommended the Shopify Plus platform because it has built in B2B functionality and integrates easily with most third party software companies. Shopify is easier to work with than other platforms which makes development time faster and cheaper. Shopify has the best built-in user experience of any ecommerce platform and introduces improvements faster and more often than any other platform on the market.

The development process was divided into two phases in an effort to quickly stand up a brand new site and user experience. Together with QC Supply, Ecommerce Partners divided all tasks into a prioritized list and got to work.

ECP delivered a fast (Google Pagespeed 77 mobile / 94 desktop), ADA Compliant B2B and B2C Shopify website with a dedicated B2B Pro Portal that allows admin users to create locations, sub users and permission based product purchasing using Shopify Companies, Catalogs and Location functionality.

"In the situations where we needed something done more quickly and more efficiently we would give that to Ecommerce Partners just because they were able to be more responsive and and act more quickly the other the other company is much larger and in some ways was kind of bogged down by their processes, their own internal processes."

“Ecommerce Partners is professional, knowledgeable, and flexible. Those were kind of like the big three things that I really leaned on because I swear there were times and that I felt like EP was probably thinking, ‘What are these people doing’? But they always just led us through it and were super patient. I really just appreciated that. I really appreciated that partnership.”

"We went with them because it was a general feeling of trust based on what they showed us they can do and the sense of their technical capacity. They came with ideas that sounded right. In the end, depends on the salesmanship and the technical ability and they were strong in both."

"Communication has been great. They're always open and there when I need them. I'm probably not the most structured person but their weekly meetings kept things moving forward on track. I do appreciate the package and the communication feels tailored to exactly what I'm looking for as a consumer, and that's very important to me."

"We were early online. We built a website way back in the late 90s on, I believe and then eventually it was time to move. And so when we were building a new site, we were introduced to Ecommerce partners and they built our first site for us. I love those guys. They are a solid team and the big thing is that they care. No matter when 24-7 if we had a problem, they’re all over it."

When we switched to Ecommerce Partners it made me realize the good work I get out of the team, how professional they are, and how they're willing to, even though they didn't build the site, come in and again become our trusted support team for the day-to-day operations."

About Us

At Ecommerce Partners, our journey began with a simple idea: even the most complex eCommerce challenges can be solved with genuine expertise, a friendly approach, and a healthy dose of coffee-fueled creativity. What started as intimate brainstorming sessions among a small team of developers, strategists, and problem solvers has grown into trusted partnerships with mid-sized eCommerce businesses. We don’t aggressively push contracts—we earn your trust with transparent communication, honest scoping, and by always keeping our promises.

Our mission is to empower mid-sized eCommerce businesses with expert, flexible, and trustworthy development solutions—delivered responsive, hands-on partnerships—while our vision is to create smart, scalable Shopify solutions and to educate you along the way, ensuring that every decision is clear and every step forward is taken with confidence.

Let’s build something extraordinary together!

Frequently Asked Questions

FAQs to address the most common questions we get asked.

If you can't find the answer, we're happy to dive in deeper. Fill out the form below!

Why hire a Shopify expert instead of doing it myself?

While Shopify is user-friendly for basic setup, scaling a successful ecommerce business often requires technical expertise. Hiring a Shopify expert or agency saves you time and helps you avoid costly mistakes. We bring years of experience and in-depth knowledge of Shopify’s platform, so tasks that might take you days or weeks to figure out can be done in hours. Moreover, experts can implement advanced customizations (for design, checkout, etc.) that aren’t possible with DIY methods. As one source notes, when your project gets complex – “scaling your store, migrating from another platform, or customizing every detail – a Shopify Plus development partner can make all the difference,” ensuring you get the most out of Shopify’s capabilities. In short, a Shopify expert helps you launch faster, run smoother, and ultimately drive more sales by doing things the right way from the start.

How long does it take to build a Shopify store?

Timeline depends on complexity. A simple Shopify store using a pre-made theme with minimal customization can be launched in a matter of weeks. On the other hand, a fully custom design and Shopify Plus build with integrations can take a few months. For example, our typical project for a mid-sized ecommerce site (custom design, some custom features) might be ~8–12 weeks from kickoff to launch. We work with you to define milestones and a schedule. If you have a specific launch date in mind (say, to align with a marketing campaign or seasonal launch), let us know – we can often prioritize critical features for that deadline and roll out secondary features in phases. During the free consultation, we can usually give a rough time estimate based on what you need.

Can you help with an existing Shopify store (not just new builds)?

Absolutely. A large portion of our work is with existing Shopify merchants. We can do a comprehensive audit of your current store – reviewing your theme code, app setup, site speed, SEO, etc. – and then execute improvements. Whether you need a visual redesign, a new feature (like adding subscriptions or multilingual support), or a cleanup of issues, we’re on it. We also assist with platform migrations (e.g., from Magento, WooCommerce, BigCommerce to Shopify), where we carefully import products, customers, and orders and ensure redirects/SEO are handled. If your store is already live and you’re experiencing problems (slow speed, bugs, integrations not working), we offer troubleshooting and rescue services. Think of us as your on-demand Shopify tech team – we can engage for a one-time fix or as ongoing support.

Is Ecommerce Partners a certified Shopify Plus partner?

Yes, Ecommerce Partners is a recognized Shopify Partner, and we have extensive experience with Shopify Plus. While Shopify doesn’t have a public “certification” program in the way some platforms do, being a Shopify Plus Partner means we’ve demonstrated expertise in launching and managing Shopify Plus stores. We’re very familiar with the exclusive features of Plus (like Scripts, Flow, Launchpad, wholesale channel) and have direct contacts within Shopify to escalate support for our Plus clients. If you’re considering Shopify Plus, we can provide guidance on the upgrade process and leverage our partner resources to your benefit. On the flip side, if you’re not on Plus, rest assured we bring the same level of expertise to regular Shopify projects too.

What kind of ongoing support do you offer after launch?

We offer ongoing support plans tailored to your needs. This can range from ad-hoc support (you reach out when you need us for updates or issues) to a more structured monthly retainer where we allocate a certain number of hours to your account for continuous improvements. Support can include updating apps and themes, security monitoring, performance tuning, adding new features as your needs evolve, and just being there to answer questions (“How do I do X in Shopify?”). We also provide emergency support for critical issues – if your site goes down or something is preventing checkouts, we treat it with top priority. Our goal is to build a long-term relationship, acting as an extension of your team. Many of our clients have been with us for years, continually evolving their stores. We’re happy to be your go-to Shopify experts for the long haul.

Can you integrate Shopify with [XYZ] system?

In most cases, yes. We’ve yet to meet a system we couldn’t integrate with Shopify in some fashion. We use Shopify’s API and sometimes middleware to connect Shopify with ERPs (like SAP, Oracle, Microsoft Dynamics), CRMs (Salesforce, HubSpot), IMS/WMS (inventory and warehouse systems), POS systems, and more. Integration might involve real-time sync or periodic batch updates, depending on the system’s capabilities. If the system has its own API, we can likely write a custom integration or use existing connectors. For example, we’ve integrated Shopify with accounting software (QuickBooks, Xero), marketing platforms (Mailchimp, Klaviyo), and even bespoke in-house databases. During our consultation, let us know what system you need Shopify to talk to. We’ll outline an approach – whether it’s using an existing app or a custom integration. Our powerful ECX (E-Commerce Exchange) platform was built for this purpose: to act as a flexible connector between Shopify and any other system, ensuring data flows smoothly no matter how complex your tech stack is.

What is Shopify Plus and do I need it?

Our team provides continuous maintenance, 24/7 support, and regular updates to keep your store running smoothly.
