Frequently asked questions

Ceven uses the Calculate Tax Rate action to send the customer address and product type to Quaderno in real time. Quaderno then returns the exact tax percentage based on the latest global tax laws. The agent can then use this rate to populate a checkout page or a final invoice. This ensures you never under collect tax due to outdated tables. Because the agent handles this before the invoice is finalized, you can provide customers with an accurate total including tax during the purchase flow rather than billing them for the difference later.
Yes. Once an invoice is created and finalized, the agent can trigger the Deliver Invoice action. This sends the professional PDF directly from Quaderno to the customer email on file. You can build a workflow where the agent waits for a payment confirmation from your payment processor and then immediately delivers the final invoice. This eliminates the need for a human to manually click send for every transaction, which is essential for businesses processing hundreds of small digital sales every day.
When a new customer enters a tax ID, the agent uses the Validate Tax ID tool to check the ID against the official government database via Quaderno. If the ID is valid, the agent can automatically update the contact record to be tax exempt or apply a reduced rate. If the ID is invalid, the agent can draft an email to the customer asking for the correct details. This ensures your tax records are clean and you are not illegally exempting customers who provided fake or mistyped IDs.
One critical quirk of the Quaderno API is that you cannot modify certain fields once an invoice is marked as paid or delivered. For example, you cannot change the line items or the total amount after the invoice has been sent to a customer. The agent is programmed to check the status of the invoice first. If the invoice is already delivered, the agent will instead suggest creating a credit note to adjust the balance rather than attempting a direct update, which would result in an API error.
Yes. The agent can create new products, update existing ones, or list your entire catalog. This is useful when you sync your product launch from a tool like Notion or Shopify. The agent can read the new product details and automatically create the corresponding product in Quaderno with the correct tax code assigned. This ensures that as your product line grows, your tax engine stays in sync without you having to manually map every new SKU to a tax category.
The agent can list and retrieve evidence objects to ensure you have the required documentation for a specific jurisdiction. For example, if a jurisdiction requires a business registration certificate for exemption, the agent can check if that evidence exists in Quaderno. If it is missing, the agent can trigger a request to the customer via email to upload the document. Once the document is received, the agent can ensure it is linked to the correct contact record for future audits.
Ceven can automate the process of requesting tax reports. The agent can trigger a reporting request for a specific date range and jurisdiction. Since reports are generated asynchronously, the agent then uses the List Reporting Requests tool to poll for the status. Once the report is ready, the agent can notify you with the download link or even move the file to a secure cloud storage folder for your accountant, removing the manual effort of logging in to download CSV files every month.
When a refund is triggered in your payment system, the agent can create a corresponding credit note in Quaderno. It pulls the original invoice ID to ensure the credit is applied to the correct transaction. After the credit note is created, the agent can use the Deliver Credit Note action to notify the customer that the refund has been processed. This keeps your accounting books and your customer communications perfectly aligned without any manual data entry between the payment gateway and the tax platform.
