Run marketplace operations through a central data flow, not disconnected panels.
Multi-channel sales operations become difficult when orders, stock, prices, catalog data, shipping and returns are managed from separate panels. MRTSoft develops marketplace and e-commerce integration layers that connect supported sales channels with ERP, accounting, warehouse, CRM or custom operational software. The objective is not a collection of isolated API calls, but a traceable workflow in which teams can understand what happened, what failed and what requires action.
Marketplace integration designed around the operation
Every channel has different API capabilities, limits, status models and catalog rules. We first map the actual sales process, source of truth for product and inventory data, order ownership, shipping flow and exception scenarios. The integration is then designed around these rules instead of forcing the business into a generic connector.

Where the relevant platform APIs support the required operation, integrations can cover product and variant data, inventory, pricing, orders, shipment information, cancellations, returns and status updates. Channel-specific identifiers and category or variant mappings are stored in a controlled way so the central system can communicate consistently with different marketplaces.
Order management and central processing
New orders can be collected into a central operational screen or transferred directly to ERP, accounting or warehouse software. Duplicate processing, missing records and status conflicts are reduced through idempotent processing, validation and audit records. Business rules can route orders according to warehouse, company, channel, payment state or other operational criteria.
Inventory and price synchronization
Stock and price changes can be distributed from the designated source system to supported channels. We plan rate limits, batch sizes, update frequency and failure recovery according to platform constraints. This is particularly important for businesses selling the same inventory across multiple channels, where delayed updates can create overselling or inconsistent pricing.
Catalog, product and variant management
Product data is rarely identical across marketplaces. Integration design can include SKU matching, barcode and variant mapping, channel-specific fields, image or attribute handling and validation before transmission. The aim is to make catalog operations manageable without hiding marketplace-specific requirements from the team.
Shipping, cancellation and return workflows
Supported shipment creation, tracking information, order status, cancellation and return events can be synchronized with the central system. Background services process these flows independently from the user interface, while failed operations are recorded for review or safe retry.
ERP, accounting and warehouse integration
Marketplace data creates more value when it reaches the systems where the business already operates. Orders can feed ERP or accounting records, stock can come from warehouse software, and shipment results can return to the marketplace. We define ownership for each data field to avoid uncontrolled two-way synchronization.
Reliability, logging and reconciliation
Production integrations need more than successful API responses. We design structured logging, retry policies, rate-limit handling, error queues, health checks and reconciliation routines. Teams can identify records that did not synchronize and correct the cause without silently losing transactions.
Who is this solution for?
This service is suitable for businesses that sell on multiple marketplaces, process a growing order volume, repeatedly update stock or prices, or need marketplace data to flow into ERP, accounting, warehouse and internal systems. Scope is determined after reviewing the channels, API access, existing software and operational priorities.
How we deliver marketplace integration projects
We start with discovery and data mapping, document channel capabilities and business rules, design the integration architecture, implement and test critical scenarios, and then prepare monitoring and launch procedures. After go-live, the integration can evolve as channels, business rules and operational volumes change.
