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
