Absolutely. EasyRoutes supports mixed sources across both products (Shopify and Web). Bring in non‑Shopify orders by uploading a CSV, sending stops through the Routes API, connecting via webhooks/Zapier, or adding custom stops manually. Once imported, they appear alongside Shopify orders on the Orders page, can be filtered like any other stop, and can be optimized together on the same route.
