Supplier documents to Shopify purchase orders

Upload a supplier invoice, order confirmation, or packing slip. Keyline matches every line to your product variants and exports a CSV you import as a Shopify purchase order - no re-typing supplier codes.

Learns your suppliers

Keyline remembers the mapping from each supplier's item codes to your variants, so it gets faster every order.

Exports a Shopify PO

Produces a native purchase-order import CSV. Your supplier's codes never appear in it.

How it works

  1. Upload a supplier file (.csv, .xlsx, or .pdf).
  2. Confirm the supplier - auto-detected for PDFs.
  3. Review the matched lines; map any unknowns once.
  4. Export and import at Products → Purchase orders → Import.
