How to export an inventory file

Exporting a file with your company's inventory to report to the Tax Authority is a simple process.

Under the 2026 State Budget (OE2026), the communication of inventory valuation has been postponed. Therefore, Moloni ON provides two versions of the inventory file:

• Version 1_02, which corresponds to the inventory;
• Version 2_01, which corresponds to the valued inventory.

Follow the steps:

1. Go to the menu Tax Authority > Exports > Inventory.

2. To export the inventory, select the end date or predefined period.

3. Select the desired format.

4. To export the valued Inventory, select the desired costing method and the date or predefined period.

• FIFO - stands for "first in, first out," which indicates that the first products to enter the inventory will be the first to leave, meaning, to be sold. These will be sold at the price of the oldest goods, while the remaining products will be sold at the most recent price.

• Weighted average cost - means that the cost is calculated by taking a weighted average of all movements within the date range.

• Lowest supplier cost - is the lowest cost price, with applied discounts, recorded on the item's card.

5. Select the desired format.

Important: Regardless of the selected format, after transferring the file to your computer, do not attempt to open it in text editors, spreadsheets, or other similar programs, as this runs the risk of altering its format and encoding. If this happens, the file will no longer be valid by the TA services and you must generate a new file to submit again.
