Finding a key to reduce the time to market to a bare minimum? We’re in! And we have an ironclad key to rigid, inflexible eCommerce stores. Amitech Group’s branded Marketplace Connector proved its magic capability to unlock unprecedented scalability yet again.
This time, we helped General Pants Co. furnish their Shopify marketplace with multiseller capabilities while mapping taxonomy and ads for the extended product range. The brand-new multivendor store hit the market in a matter of weeks and was further carefully supported by our team.
PROJECT BACKGROUND
Marketplace scalability issues
General Pants Co. aimed to enable its partners to sell products through the existing Shopify store. Yet, the marketplace wasn’t scalable enough to accommodate more vendors without wrecking the functionality.
The client considered implementing the Marketplacer Range Extension capability to remove the seller growth barrier.
Still, the challenge remained to seamlessly integrate Shopify with Marketplacer while streamlining the data workflows and preventing potential operational lapses.
CLIENT’S OBJECTIVES
- Integrate the existing Shopify store with Marketplacer
- Extend the seller range with their partner brands
VENDOR COMPETITION WIN
To the client, Amitech Group’s rich expertise in building eCommerce ecosystems and multivendor marketplace integration tools was decisive. The team’s certification by the Marketplacer Foundations, alongside the stripes of a trusted tech partner, secured the project for us.
CHALLENGE
Taxonomy synchronization
The main technical challenge was aligning different taxonomies and rules for smart collections (products that automatically group based on data-driven criteria) between the client’s existing and new Marketplacer catalog.
To nail the job, we leveraged the Shopify to Marketplacer Connector’s capabilities to map the Marketplacer taxonomy and advertisement options to Shopify metafields.
SOLUTION
Shopify marketplace integration software
By introducing its branded Shopify to Marketplacer integration tool, Amitech Group helped the client resolve the taxonomy synchronization issues while critically reducing the time to market for the upgraded multivendor eCommerce marketplace.
The Shopify to Marketplacer Connector serves as a black box that includes the backend code, open API, infrastructure, middleware services, reporting tools, and other components provided to General Pants Co..
The resulting solution features the following capabilities:
- Seller synchronization
- Product synchronization
- Multiseller or Golden product support
- Taxonomy synchronization
- Product batch, or bulk upload
- Product and category management
- Order synchronization
- Shipping rules synchronization
- Cart items grouping
- Shipment synchronization
- Promotions synchronization
- Open API for frontend customization
- Built-in monitoring

Tech under the hood
“It is only by working in close collaboration with Marketplacer, our longstanding eCommerce tech partner, that we managed to adjust the solution to the client’s requirements so quickly and seamlessly.“
Marketplacer
The best-in-class prebuilt platform to grow fast in line with business needs. Alongside powering the Shopify marketplace integration tool, it helped the team minimize the effort in scaling the client’s seller ranges, mapping the taxonomy across a wealth of product categories, and deploying the dropshipping capability.
Shopify
Amitech Group employed Shopify as a B2B SaaS to host the Connector solution. The platform enabled the team to efficiently configure and demonstrate the Shopify Marketplacer integration app’s user interface while allowing us to bring in conveniently customizable shipping rules.
Marketplace Connector
With our branded marketplace integration tool, we’ve achieved near-instant data exchange between the Shopify and Marketplacer platforms. The solution is composable, API-driven, and cloud-ready, which helped us easily adapt it to the client’s business infrastructure and ensure futureproof scalability.
