FulfillFlex – Bulk Fulfillment

Stop wasting time copy-pasting tracking numbers. FulfillFlex lets you bulk fulfill Shopify orders directly from spreadsheets — CSV, XLSX, XLS, or TSV files — in just three clicks. Columns auto-detect in 9 languages, and carrier names match even with typos thanks to fuzzy matching. Preview every order before fulfilling so you can spot issues before customers do. If a row fails, retry only that one instead of reprocessing the whole batch. One-click rollback lets you revert fulfillments when you need to redo them. The app supports 160+ carriers built-in, plus you can add your own custom carriers. Built by a Shopify seller who ships orders every day and understands the pain of manual fulfillment workflows.
