Multi-Channel Inventory & Order Sync

Synchronize inventory levels, orders, and product data across Shopify, WooCommerce, Amazon, and eBay from a single Python codebase.

Stop manually updating stock counts across four dashboards. This package gives you a unified sync engine with channel-specific adapters, automatic conflict resolution, and retry logic that handles the inevitable API failures.

What You Get

  • Channel adapter interface with concrete implementations for Shopify, WooCommerce, Amazon, and eBay
  • Sync engine that orchestrates bi-directional inventory and order synchronization
  • Conflict resolution with four strategies: last-write-wins, highest-stock, lowest-stock, and channel-priority
  • Data normalization layer that maps each channel's quirky field names to a unified schema
  • Retry handler with exponential backoff, jitter, circuit breaker, and dead-letter logging
  • Unified data models for products, inventory, orders, and line items
  • YAML configuration for channel credentials, sync intervals, and conflict rules
  • Sample data for testing your setup before going live
  • Comprehensive test suite covering sync logic, conflict resolution, and error paths

Quick Start

1. Configure Your Channels

Copy and edit the channel configuration:


cp configs/channels.yaml configs/channels_local.yaml
# Edit channels_local.yaml with your API credentials

src/channel_adapter.py """ Abstract channel adapter interface. Every sales channel (Shopify, Amazon, etc.) gets a concrete adapter that translates between the channel's native API and our unified data models. This base class defines the contract. Why an abstract base class instead of a Protocol? - ABCs give you a clear error at instantiation time if you forgot to implement a method. Protocols only fail at type-check time, which most teams skip in practice. - ABCs let us put shared logic (auth headers, rate-limit tracking) in the base without repeating it in every adapter. """ from __future__ import annotations import logging from abc import ABC, abstractmethod from typing import Optional from src.models import ( Product, InventoryLevel, Order, SyncDirection, ) logger = logging.getLogger(__name__) class ChannelAdapter(ABC): """Base class for all sales channel integrations. Each adapter handles: 1. Authentication with the channel's API 2. Fetching products, inventory, and orders 3. Pushing inventory updates and product changes 4. Translating between native and canonical data formats Subclasses must implement every abstract method. The sync engine calls these methods without knowing which channel it's talking to.
