Adjusting contract prices using indexation
Price indexation can be used to adjust contract prices and it is available on the Contracts selection level. All contract lines linked to the selected contract are indexed up to and including the selected date. You can index contract prices according to:
• An indexation method based on a percentage (see Indexation based on a percentage).
• An indexation method based on an index group (see Indexation based on index groups).
• An indexation method based on Base amount (see Base amount indexation).
Before starting the indexation, ensure an indexation method is specified for the contract lines linked to the contracts for which you want to index prices. For details, see Contract line data fields.
The Indexation methods are defined in Supporting data . For more information on defining indexation methods, see the Supporting data documentation.Planon ProCenter automatically recalculates indexed prices if one of the following contract line items is changed before or on the last indexation moment:
• The amount
• The base amount for indexation
• The year or month of base amount indexation
• The indexation method
If you change the indexation method in the course of time, the indexation method you most recently selected is applied in future indexations. If you manually change an amount on an indexation moment, the amount is not indexed. Planon ProCenter saves the amount you entered manually and no indexation is performed. If you want to reverse a manual price change and get the amount indexed again, you can do this by changing the amount back to its previous value. Please refer to the following example.Example
Amount indexed 10% each month, starting from Feb. 1st:
January | February | March | |
|---|---|---|---|
Amount | 100 | 110 | 121 |
March 1st Indexation moment
Feb. 1st Indexation moment
Case 1: Manual price change on indexation moment
Amount is changed manually to 150 on Feb. 1st (= indexation moment). The amount is not indexed on Feb. 1st:
January | February | March | |
|---|---|---|---|
Amount | 100 | 150 | 165 |
Feb. 1st
March 1st
To undo this manual price change you should change the amount back to its previous value (=100) as of Feb. 1st. The amount will then be indexed as of Feb. 1st.
Case 2: Manual price change on a non-indexation moment
Amount is changed manually to 150 on January 10 (no indexation moment). The amount is indexed on the next indexation moment:
January | February | March | ||
|---|---|---|---|---|
Amount | 100 | 150 | 165 | 181,50 |
March 1st
Feb. 1st
Jan. 10

To undo this manual price change you should change the amount back to its previous value (=100) as of January 10.
