What are the best ERP integration options for ecommerce?

For ecommerce businesses, the most important ERP integrations are: marketplace connectors (Amazon, eBay, Walmart), storefront connectors (Shopify, WooCommerce, Magento), 3PL integrations (ShipBob, ShipStation), and payment processor reconciliation. Pre-built connectors via middleware platforms like Celigo, Boomi, or Jitterbit are generally faster to implement than custom API integrations.
