Built around the purchase order lifecycle

AutoPO integrations are most useful at the moments where PO state changes: creation, updates, receiving, and completion.

  1. created

    Create PO

    When a purchase order is created manually, by automation, or through the API, downstream systems can start their work.

    • Shopify Flow Trigger purchase-order-created workflows.
    • Webhooks Send purchase_orders/create events.
    • Accounting Create records on PO creation when auto sync is configured.
  2. updated

    Update or receive

    Operational changes can move into Shopify automation, external tools, and custom receiving workflows.

    • Shopify Flow Trigger purchase-order-updated workflows.
    • API Receive stock, list records, and archive POs.
    • Webhooks Send update events for supported PO update paths.
  3. completed

    Complete PO

    Completion can close the loop with accounting records, warehouse jobs, team notifications, and custom systems.

    • QuickBooks and Xero Create accounting records on completion when configured.
    • Shopify Flow Trigger purchase-order-completed workflows.
    • Webhooks Send purchase_orders/complete events.

Send purchase orders into accounting

Create accounting-side records without treating purchase order work as a separate spreadsheet process.
