Running the tool

In the root folder of the project (after activating your virtual env and installing the dependencies):

  • Place all the xml files you downloaded in that folder
  • run python
  • Or run python -p your/path/to/invoices to provide a custom path to your invoice folder

The results

The results are organized in two parts: a breakdown of all your invoices and a summary with the relevant values

Result 01

Some invoices contain two parts, which in the summary is shown as a two separate invoices, a taxable and a non-taxable amount, the interesting part is the taxable amount, which is the one that has a 12% added value tax.

In the summary you can find the total tax value, and the total value that has taxes, ussually you only need the total_with_taxes value, to add that in your tax declaration.

All other values are there for your information and so you can check the calculation is correct.

I hope you find this useful and helps you deduct taxes faster.
