Furthermore, 1Digital Agency created a product category hierarchy to facilitate navigation and improve customer search experience.

Spiceology is a chef-owned brand that sells herbs, spices, and custom blends. While it already had a Shopify store, it wanted to shift to the BigCommerce platform and integrate it with its WordPress CMS. For this project, Coalition Technology developed a headless BigCommerce solution.
The BigCommerce web developer migrated the client’s 56,000 customers, 44,000 orders, 405 products, and 1,000 URLs to the new BigCommerce website.

Inovelli — a designer and manufacturer of smart home products — was experiencing data silos and fragmented user experience due to its separate eCommerce, customer support, and community forum platforms. To solve this, Codup migrated all data to BigCommerce and integrated Zoho Desk, Discourse, and Auth0.
Zoho Desk allowed the client to control and access its CRM from BigCommerce. It also segregated customers into B2B and B2C segments for more accurate data mapping and targeting. Plus, Auth0 enabled the client’s team to access all platforms with a single ID and password.
Within three months, the customer onboarding process became more streamlined, the user experience improved, and organizational efficiency increased significantly.

Direct Plants Ltd is a mail-order business that sells nursery plants and trees to customers across the US. Originally, it had three selling platforms — eBay, Amazon, and its own website — but was having difficulty managing and updating them all. So, it partnered with Frooition for a solution.
The BigCommerce web designer migrated the client’s eBay and Amazon to Linnworks. At the same time, it developed a new website on BigCommerce. It also trained the client’s team to use both platforms and maximize their return on investment (ROI).
After six months, Direct Plants Ltd increased sales by 60% compared to its busiest year and turned over more than $1.5 million in sales.
