Create an Accounting Invoice for Every Paid Shopify Order Automatically

Manually re-typing Shopify orders into your accounting software is slow and error-prone. This workflow turns every paid order into a properly itemized invoice in QuickBooks (or Xero) — line items, tax and customer matched — the moment payment clears.

  1. 1

    Trigger on payment

    A Shopify Trigger on orders/paid fires only for orders that are actually paid, not just placed.

  2. 2

    Shape the invoice

    A Code node maps Shopify line items, discounts and tax into the invoice structure your accounting API expects.

  3. 3

    Match or create the customer

    An HTTP Request finds the customer in QuickBooks by email, creating them if new, so invoices attach to the right ledger.

  4. 4

    Create the invoice

    A second HTTP Request posts the itemized invoice with the correct tax code and order number as the reference.

  5. 5

    Catch failures

    An IF node routes any error to Slack so a failed sync never silently disappears from your books.

Frequently asked questions

Xero instead of QuickBooks?

Yes — swap the two HTTP Request nodes for Xero's invoice endpoints. The Shopify side and the mapping Code node stay identical.

What about refunds?

Add a parallel branch on the `refunds/create` topic that posts a credit note. Keeping refunds in sync is what makes month-end reconciliation painless.
