How to use this function

Check XML invoices with Vera

Learn to supply an invoice folder, read the document summary and handle items needing review.

The explanation and a short practice take about 5–8 minutes. Processing and your questions can extend the session.

Start this course

Codex

Open Codex on your computer with Vera installed and select @Vera in a chat.
Copy the request below, paste it into the chat and send it.
Turn on Codex voice in this chat. The assistant will guide you to open the second working chat in another window: listen and ask questions here, and watch the work and results there.

Request to send to Vera

Vera, start the prepared lesson “Check XML invoices with Vera” in English. Teach me to use this function with the included fictional files. Use this chat to explain the steps and answer my questions. Create or resume a second working chat to run the current workflow, and guide me to open it in another window. Help me turn on voice. Show me the actual results, then let me try the practice exercise.

The fictional lesson files are already included in the plugin. You can also take the lesson in writing. This button copies the request; the lesson starts when you send it in Codex.

Start in Claude Cowork

Open Cowork with Vera installed and a connected folder for the lesson. Copy and send this request: the lesson takes place in writing in one conversation.

Request to send to Vera

Vera, start the prepared lesson “Check XML invoices with Vera” in English, in writing in this single Cowork conversation. Use the included fictional files. Explain each step, run the current function and show me the actual results. Pause for my questions and guide me through the practice exercise. Do not use voice or a second chat.

When to use it

Arco Practice has received three March XML invoices for a fictional client. It wants to identify the documents and check that they are readable and consistent before continuing the accounting work.

This function prepares and checks received documents. Accounting entries and submission to SdI follow their own processes.

Files and request

Open invoice-01.xml, invoice-02.xml and invoice-03.xml. These are teaching FatturaPA files with fictional identifiers. The case note states the period and the expected batch total: EUR 2,440.

Vera, check the March XML invoices in this folder. Show the documents received, their amounts and anything that needs review.

Run the workflow

Vera imports the folder into the teaching case and reads the XML files through the function’s parser. Check which files are included.
In the working chat, the workflow extracts numbers, dates, parties and amounts, checks structure and reports anomalies or possible duplicates.
Open the new summary. Vera links findings to the source files and identifies useful checks before the next step.

Use the result

Invoice summary: find one document and locate its number, date and total in the XML.
Anomaly list: inspect the affected file, observed problem and required check. The document count shows the coverage.

Compare the three received documents with the summary and batch total. Resolve a finding against its source; this check does not decide deductibility or confirm bookkeeping.

Pause and check

Before running: identify the folder and month to check.
At the result: open one row and its XML; locate where any anomalies would appear.

These pauses help you learn how to use the function. They are not a technical detail quiz.

Try it yourself

Add invoice-04.xml to a fresh practice folder and request a check of all four invoices, including April.

The new summary must include the fourth invoice and distinguish the two months. Explain where you would investigate a problematic file.

To repeat this at work, select the client folder and ask Vera to check the received XML invoices. Review the summary and findings before continuing.
