Keep track of your expenses and include them in your invoices

  • Record all your expenses and show them in a table view
    • The data can be searched- and filtered (see screenshots)
  • All (billable) expenses will be automatically included in your invoices
    • Negative amounts allow for complex bookings, budget and invoice adjustments
  • Manage expenses via API
  • Export expenses in: Excel, PDF, HTML
  • Support for custom-fields
  • Include expenses in Kimai export module
  • Import expenses from Kimai 1

Expenses will be assigned to free configurable categories and each category has:

  • name
  • visibility flag
  • default cost
  • color
  • help text (will be shown when creating an expense)
  • description (will be copied into the expense description upon selection)

Each expense has the following fields:

  • a date-time
  • category (see above)
  • user
  • project (and customer)
  • activity (optional)
  • description (free text field)
  • the cost (can be hidden for default user, if you use default cost via category)
  • an amount (see it as multiplier, use 1 if you want to charge the cost only)
  • a billable flag (non-billable expenses will not be added to your invoices)
  • an export flag (to make sure, that each expense will be invoiced only once)

If turned on, Expenses count towards budgets and revenue statistics.

Expense summaries are displayed on the detail pages for customer, project and activity.


When logged in as user with sufficient permissions, you will see the expense administration screen at /en/expenses/.

During the installation a Demo category will be created, so you can immediately start adding expenses. You can rename it after your first test.


As expenses will be automatically included in your invoices, you might want to distinguish between expenses and timesheets. The invoice template variable ${entry.type} contains that info. The value will be expense and can be used for example in Excel with ifthan formulas or in combination with a conditional format.

The invoice template variable ${entry.category} will contain the category name of the expense.

The search supports filtering by the fields:

  • daterange
  • customer
  • project
  • activity
  • expense category
  • user
  • billable
  • exported

The free search term will query the field:

  • description

Additionally, you can filter for custom fields by using a search phrase like location:homeoffice. This would find all entries with the custom field location matching the term homeoffice.

The search terms will be found within the full value, so searching for office would find:

  • I love working in my office
  • Office
  • This office is beautiful
  • Our offices are very noisy

Attention: checkboxes have the values 0 (not checked) and 1 (checked).

You can mix the search term and use multiple meta-field queries:

  • location:homeoffice hello - find all entries matching the search term hello with the custom field location matching the term homeoffice
  • location:homeoffice contract:fulltime - find all entries with the custom field combination: location matching homeoffice and contract matching fulltime
  • expired:0 finds all items whose expired checkbox is off

There are also special operators, which can be used in conjunction with custom fields (since Kimai 1.19.1):

  • The   empty string (e.g. location:) will find all entries whose value in the location field is either empty or not existing
  • The ~ search term (e.g. location:~) will find all entries that are missing the custom field (created before the field was created)
  • The * search term (e.g. location:*) will find all entries that have any value in the location field (basically the opposite of ~)
