## Article overview

        This article explains Batch invoice conversion in the web app as a practical reference for European e-invoicing. It defines the topic in plain language, places it in the compliance context, and connects the explanation to invoice formats such as XRechnung, ZUGFeRD/Factur-X, UBL, and CII.

Batch conversion is the web route for several invoices. It is available with Professional and Enterprise plans and accepts up to 10 files in one upload.

        ## How to use this guide

        Use the article as a starting point before changing a finance or ERP workflow: identify the applicable country rule or standard, decide which structured format is expected, validate the generated XML, and keep a documented exception process for invoices that require manual review.

## How batch conversion works

For How batch conversion works, this sequence gives the practical order of work.

- Open the converter and select several source files.
- Choose the required target format and start the batch.
- Wait for processing, then open each invoice in the batch overview.
- Review uncertain data and validation results before downloading the completed files.
## What batch mode does not change

A batch saves upload and navigation work. It does not make source checks optional. One unclear invoice can still require correction while other files complete.

## When batch is the right choice

Use batch for a small recurring stack of invoices that a person still reviews. For a fully connected system workflow, see the [invoice conversion API guide](/en/blog/invoice-conversion-api).

## Start a web batch
