Why Shopify Plus is the Optimal Choice for Established Businesses

Shopify Plus stands out as an advanced solution for established businesses aiming to enhance their online presence and scale operations efficiently. This elite platform offers a suite of features that are designed to cater specifically to the needs of large-scale enterprises, emphasizing customization, advanced analytics, and superior support. Here’s a closer look at why Shopify Plus is the preferred choice for businesses ready to take their e-commerce to the next level:

Enhanced Customization and Control

Shopify Plus provides a significantly enhanced level of customization and control compared to Shopify’s standard offerings. With features like custom scripts and customizable checkout pages, Shopify Plus allows businesses to tailor the shopping experience precisely to their brand’s needs and customer expectations. These customizations not only improve user experience but also boost conversion rates by reducing friction during the checkout process.

Advanced Reporting and Analytics

Understanding and responding to customer behavior is critical for scaling businesses. Shopify Plus offers advanced reporting and analytics tools that provide deeper insights into sales patterns, customer engagement, and inventory management. These tools allow businesses to make informed decisions that can directly impact their growth and profitability.

Superior Cart Recovery Tools

Cart abandonment is a significant challenge for online retailers. Shopify Plus addresses this issue with advanced cart recovery tools such as abandoned cart recovery emails and retargeting ads. These features help re-engage customers who have left items in their carts, significantly increasing the chances of completing those sales.

Scalability for High-Traffic Volumes

For businesses experiencing or anticipating high traffic volumes, Shopify Plus offers unparalleled scalability. The platform is designed to handle large amounts of traffic and transactions without compromising on performance, ensuring that your online store remains fast and reliable during peak times.

Dedicated Support and Community

Shopify Plus users benefit from dedicated account management and access to a vibrant community of similar-sized businesses. This support can be invaluable in navigating the complexities of scaling an e-commerce operation, providing both technical guidance and strategic insights.

Multilingual Checkout

Expanding globally requires a platform that can accommodate multiple languages. Shopify Plus supports checkout pages in 20 different languages, compared to only 5 in the basic Shopify plan, making it an ideal choice for international sales.

Custom Solutions We've Built

TAX EXEMPTION FUNCTIONALITY

SPECIALIST ID

PROBLEM

Specialist ID provides shoppers with lanyards, ID badge holders, and badge reels at wholesale prices. Some of their clients are tax-exempt but they had no way of directly sending Specialist ID their certificate for approval. The company was clearly losing business due to this obstacle.

SOLUTION

The team of expert developers and programmers at Optimum7 was able to create a tax-exempt functionality right on the clients’ website for customers to use. This functionality allows tax-exempt customers to apply their certificates to the Specialist ID database. Specialist ID can now approve any pending tax-exempt clients on the backend and speed up the conversion process.

Rated 5 out of 5

Optimum7 has proven to me that they are an excellent Shopify development agency. They have provided me with expert SEO consultation, support, and services over the past year. They really took ownership of the entire process and exceeded my expectations. They have proven to me that they have the “chops” to consistently drive business results for my company with their ongoing support. It is great to have a partner like Optimum7 as they have freed me to focus on other key areas of my business while they devise a digital strategy (email marketing, social media marketing, etc.) for my eCommerce store. With this confidence and peace of mind, I will continually be improving my online presence and business. Traffic is double over the same period last year (2019) and sales are up 400%. Really great stuff! Optimum7 has been able to integrate a product customization feature to show our customers a preview of their custom-designed product before adding it to the cart. This has been invaluable for both us and our customers.
