Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureStop copy-pasting tracking numbers one row at a time. Drop your spreadsheet — CSV, XLSX, XLS, or TSV — and FulfillFlex turns it into Shopify fulfillments in three clicks. Columns auto-detect in 9 languages. Carrier names match even with typos. Every order shows up in a smart preview before anything ships, so you spot issues before customers do. If a row fails, retry only that one — never the whole batch.
Stop copying tracking numbers one by one. Your carrier (DHL, FedEx, Estafeta, 99 Minutos, RedPack) hands you an Excel with hundreds of trackings. Nuvark uploads it and fulfills all orders at once. A smart preview catches errors before anything runs. Full history logs every upload with row-by-row detail. Works with any carrier.
