Why do duplicate invoices appear?
Duplicated invoices may appear when you connect both your sales platform and your payment processor, and they both send to Quaderno the information referring to the same sale.
When connecting native integrations like WooCommerce, Shopify, Amazon FBA, EasyDigitalDownloads, Learnworlds or ThriveCart, make sure you don’t connect your payment processor too. This could lead to duplicate invoices.
To stop the duplicates being created, head to integrations in your Quaderno dashboard and disconnect any PayPal or Stripe accounts you might have configured along with your native integration.
To cancel out existing duplicates, navigate to the invoice you’d like to cancel and select Issue credit note under the three dots “… ” button.
