Invoicing contract changes in Koho – applying price changes to invoices or periodic invoicing

Prev Next

When changes are made to the contract that affect its monthly price (e.g. changes in the number or price of products), these changes can be transferred to the invoice using Koho's Contract changes tool. The tool can be found in the Contracts menu.

Content of the instructions:

  1. Overview of changes

  2. Edit the change interval

  3. Invoicing a single change

  4. Invoice multiple changes at the same time


  1. Overview of changes

The Contract changes view shows the following information:

  • Customer Name

  • Name of the contract

  • Change Time Span (Start to End)

  • Days

  • Size of the monthly change

  • By clicking on an individual row, you can see more detailed information about the change in question.


  1. Edit the change interval

You can adjust the validity of the change from the top of the time period:

  • Default values: The start date is set to the date on which the change is saved, and the end date is set to the last day of the invoice period for which the invoice has already been generated.

  • Editing as needed: If the contract amendment has been agreed to start earlier than it has been entered into the system, change the time interval to correspond to the agreed time.

Version comparison

By clicking on the "Before" or "After" headings, you can compare the version of the agreement before and after the change.
