ETERMART EnablesEnd‑to‑End Automation for Multichannel E‑Commerce Integration
We built a tailored Multichannel E‑Commerce integration software solution for Etermart to enable automation across Amazon (SP‑API), Shopify, and Magento—automating orders, syncing inventory/pricing in real time, and delivering secure, scalable analytics
Client: Etermart
Timeline: 4 months development
Budget: $40k
Catalog scale: 70,000+ SKUs
Channels: Amazon (SP‑API), Shopify, Magento
Highlights
Built a middleware “single source of truth” for multi-channel operations
Real-time inventory, order, and pricing synchronization across marketplaces
Workflow automation for order handling, document processing, and process tracking
Custom Amazon SP‑API integration (not a generic connector) for scalable pipelines
Secure, modular architecture designed to add/remove channels without disruption

THE CHALLENGE
The Hidden Cost of Manual Multichannel eCommerce Management
Etermart operated across Amazon (SP‑API), Shopify, and Magento, but growth created a scalability bottleneck. Disconnected systems and manual workflows caused delayed processing, inventory inaccuracies, and repetitive tasks that increased errors and limited the ability to scale in a competitive market.
Key challenges
Manual, error-prone workflows slowing down multi-channel operations
Disconnected systems causing inconsistent inventory and pricing
Delayed order processing impacting seller metrics and customer experience
Lack of a unified view for sales reporting and operational decision-making
THE SOLUTION

Inter-soft built a bespoke, high-performance middleware layer that acts as the central nervous system for Etermart’s multichannel e-commerce operations—standardizing data, automating workflows, and ensuring real-time control across marketplaces.
Real‑Time Data Synchronization (Multi‑Channel Integration) Centralized syncing for inventory, orders, and pricing across Amazon, Shopify, and Magento—eliminating silos and improving accuracy.
Intelligent Workflow Automation Automations for order handling, document processing, and workflow tracking—reducing errors, speeding operations, and freeing teams for higher-value work.
Custom Amazon SP‑API Integration A purpose-built SP‑API engine with scalable pipelines for orders, inventory, and pricing—securely processing high volumes while keeping Etermart in full control of its data.
