A supplier can change a quotation after sending it. Each change creates a new revision. The screen **Revision - Comparative** puts the revisions of one quotation in columns, so you see what moved. It compares revisions of one supplier. To compare different suppliers, use [Compare quotations of an RFQ](../request-for-quotation---rfq/compare-quotations.md).

## Before you start

The quotation must have at least one revision. A quotation that was never changed after it was submitted has none. If it has none, the screen shows "This quotation has no revisions to compare."

## How to open the comparison

1. Open **Procurements > Quotations**.
2. Find a quotation whose **Ref No** has a number in brackets, for example "Q1 (1)".
3. Click the **Compare Quotation** icon (mark 2 in the picture) in the **Actions** column.

![The Quotations list. Mark 1 is the Ref No column, where a number in brackets shows a revision. Mark 2 is the Compare Quotation icon of that row.](../media/quotation-list-compare-icon.png)

## How to read the table

The first column is **Parameter**. Then there is one column for each revision: **Revision 0**, **Revision 1** and so on. The last column is the current state.

The table has two parts:

- **Bid Details** (mark 1): **Validity**, **Delivery Date**, **Credit Period**, **Payment Terms** and **Net Amount**.
- **Pricing Details** (mark 2): one row for each material, with its category, quantity, unit and specifications. Each cell shows the rate and the amount for that revision.

Next to a value, a small arrow shows the change from the revision before it. A red arrow means the change is worse for you. A green arrow means it is better. For dates and credit period the change is in days (d). For the net amount and the rates it is in percent.

A material that a revision did not quote has a dash or an empty cell.

## How to save the comparison

Click **Export to Excel** (mark 3 in the picture of the table). The system downloads the same table as a file.

## Rules to know

- Revisions are shown oldest first.
- The current state is shown as the last column when the quotation is **Negotiating**, **Submitted**, **Awarded** or **Awarded to other**.
- A change is calculated only when the revision before has a value above 0.

## If something goes wrong

| What you see | What to do |
| --- | --- |
| This quotation has no revisions to compare. | The quotation was not changed after it was submitted. There is nothing to compare. |
