# How do I export a quotation as a CUF file?

With a **CUF file** (Calculatie Uitwisselings Formaat) you pass the estimate of your quotation on to other software that supports CUF, such as a calculation package or a project administration. That way you don't have to retype the quotation there. Your quotation doesn't have to come from a CUF file for this: you can export any quotation as CUF.

| The CUF export is only available in Belgian and Dutch environments.

## Downloading a CUF file

1. Open the quotation.
2. Click **Download** above the quotation lines and choose **CUF**.

Robaws first saves the quotation and then creates the file. The file is called *CUF_* followed by the quotation number, for example *CUF_O260012.xml*.

## What is in the file?

| In your quotation | In the CUF file |
| ---- |
| Number, **Concerning** and customer | Project number, project name and client |
| Titles and chapters | Groupings, with the same structure, also for subchapters |
| Quotation lines | Estimate lines, with the description, the quantity, the unit and the VAT percentage |
| Line detail of a line | Per unit: the hours and the hourly rate for labor, and the cost price for material, equipment, subcontracting and other costs |
| Item number of the item on the line | EAN code |
| Total excluding VAT | Contract sum |

A few rules when exporting:

* Robaws passes on the **cost prices** per line, split over the cost types. The difference between your cost price and the total excluding VAT of the quotation, so your margins, surcharges and discounts, is in the file as a single amount **Opslagen**.
* CUF only knows labor as hours times an hourly rate. A labor line in the line detail therefore always counts as hours, even if you use a different unit.
* Only the lines that count in the total are included. [Text lines, variants and options](https://support.robaws.com/en/article/working-with-line-types-and-chapters-536ga0/) are not in the file.
* The CUF file is meant to pass your estimate on to other software, not to copy a quotation within Robaws. If you load the file into a quotation again, you get a different quotation: the lines are grouped differently and the amount **Opslagen** is not read. Your margins, surcharges and discounts are therefore lost and the total no longer matches. To copy a quotation, use [Duplicate](https://support.robaws.com/en/article/quotations-18y2inr/#2-action-buttons).

## The file cannot be created

Robaws checks the file against the official CUF format (version 4.003). If the data of your quotation doesn't meet it, Robaws doesn't create a file and you get the message *The CUF file could not be generated: the available data does not produce a valid CUF document*, with the details of what is wrong underneath. Adjust the data mentioned in your quotation and download the file again.
