Financing
You know that installments schedule a source's money instead of adding to it, what an installment carries and where you add, change and delete installments.
An installment is one scheduled payment out of a source's **Amount**. You add installments when a financier pays in parts. For example, a fund pays 40% at signature, 40% on the first shooting day and the last 20% when you deliver the final accounts.
Installments only split the source's **Amount** and give each part a date. If you split a €500,000 fund into three installments, the source stays at €500,000, and the plan total does not rise to €1,000,000. Every total in the plan adds up sources only, never installments. This also applies to functions in a formula that add up the plan's sources.
Installments give each source a payment schedule: each installment carries its own amount and its own milestone or date, and the **Set Cash Flow Rule – Installments** dialog of the source shows both.
Installments also decide what counts as received. An installment counts as received once its date has passed. In the **Received** column, KOSMA then shows a check mark  in its row. Once a source has installments, KOSMA uses the dates of the installments and ignores the source's own cash flow rule. A source whose first installment dates have passed then shows as partly received. Without installments, KOSMA counts the cash flow rule of a source date by date: each date that has passed adds its own share. See [what Received and Outstanding mean](/kb/article/what-received-and-outstanding-mean).
An installment has a name, an amount, a milestone or a date, and a payment delay. The payment delay can be negative: the money then arrives that many days before the milestone or date. You enter the amount as a number or as a percentage of the source. The currency of an installment is always the currency of its source: if you change the currency of the source, KOSMA changes it for all its installments. An installment has no status, and the **Status** cell of an installment row stays empty.
Company, effect, tax, tags, notes and attachments belong to the source. An installment has no details panel of its own.
In the grid, you cannot type into an installment row: its number, description and amount are locked. You add and delete installments, and set their names, amounts and dates, in the **Set Cash Flow Rule – Installments** dialog of their source. To open it, select a source or one of its installments and click  **Installment**. If you select an installment and click  **Delete**, KOSMA also opens this dialog and deletes nothing.
Each installment is one row in the dialog. To add an installment, click  **Add**. KOSMA gives the new installment the part of the source amount that the other installments do not cover yet. If they already cover all of it, the new installment starts at 0, and you move an amount onto it from another installment. A source can have up to 10 installments. KOSMA names a new installment *Installment 2*, *Installment 3* and so on, in English in every interface language. You can change the name.
To delete an installment, click  **Delete** in its row. KOSMA adds its amount to the last remaining installment, so the installments still add up to the source amount. You can also delete the last installment. After **Ok**, the source has no installments, and its own cash flow rule applies again.
**Ok** stays greyed out until the installments add up to the source amount. Every installment also needs an amount above zero and a milestone or a date. If you deleted every installment, **Ok** is active.
If you can only read the plan, **Installment** and **Delete** are greyed out. See [what your licence includes](/kb/article/what-your-licence-includes).
