Invoices and Taxes

In a Kanorio store, "Invoices and Taxes" refers to the sales documents (such as electronic invoices, qualified invoices, or tax invoices) that you, as a merchant, are legally required to issue to customers when they purchase products from you.

Kanorio's invoicing system is completely decoupled from payment processing: regardless of which payment gateway (e.g., PAYUNi, SHOPLINE Payments, LINE Pay, or JKOPAY) a customer uses, as long as you have enabled a local invoice service provider in "Website Settings › Invoices" in your dashboard, the system will automatically handle the issuance, voiding, or allowance (credit note) upon successful payment or refund.

What can you achieve with this category?

• Distinguish between "Kanorio's platform subscription invoices issued to you" and "product sales invoices you issue to customers," as well as tax reporting principles for different markets.
• Understand the automated lifecycle of tax documents: automatic scheduling upon payment, automatic cancellation for full refunds before issuance, and how the system determines whether to "Void" or issue a "Credit Note" based on local tax regulations after a refund.
• Enable or switch service providers in "Invoice Management" and learn about downloading invoices, resending notifications, and the automatic retry mechanism for failed issuances in the order "Invoice" tab.
• Complete the credential integration and sequence number settings for Taiwan's three major electronic invoice value-added centers (Amego, ECPay, and ezPay).

How is this different from other categories?

• Division of labor with "Payments": handles collecting money from customers and payouts; this category handles the issuance of sales documents. You do not need to use the same company for payments and invoicing (e.g., you can use SHOPLINE Payments and LINE Pay for collection, while using Amego or ECPay for electronic invoicing).
• Division of labor with "Subscription and Billing": This category covers "product invoices you issue to customers"; if you need to view or download "invoices/receipts for your Kanorio Pro/Business subscription and monthly platform fees," please visit .
• Division of labor with "Architecture and Security": The API keys and HashKeys you enter for value-added centers are securely stored using Google Cloud KMS envelope encryption. For technical details, please refer to .

Quick tips before you start

• Kanorio is not a value-added center and does not file taxes for you: You must first open an account, sign a contract, and configure sequence numbers with your local electronic invoice service provider (value-added center) before entering the obtained API credentials into your Kanorio dashboard.
• Only 1 invoice service provider can be enabled per business location: You can pre-fill credentials for multiple service providers, but only one will be active in "Invoice Management" to handle automatic issuance for new orders.
• Credentials for service providers that have issued invoices are protected: Once a service provider has successfully issued an invoice, the system prevents the deletion of those credentials to ensure that historical orders can still be voided or credited automatically if a refund occurs later (if you wish to switch, simply move the current provider to "Disabled" in Invoice Management).
