Scenario:
The entity currency is Euro (EUR)
The project currency is US Dollar (USD)
Within the project:
The project currency (USD) is set
The client currency may be different, but the project currency always takes precedence
The project exchange rate (USD) is defined: only one exchange rate can be applied to the entire project. This is the project’s base exchange rate
Co-contractors follow the project currency
The project currency is the highest-level currency and overrides all others (USD)
Project billing:
The exchange rate is automatically applied based on the invoice date. It may therefore differ from the project exchange rate and is calculated automatically (USD).
All billing items are expressed in the project currency (USD).
⚠️ For invoices created in the future, the exchange rate applied will be the latest known rate (USD).
In Project > Billing > Invoices, you can use the grey toggle to switch the currency display (USD or EUR).
When recording the invoice payment, you can choose the payment currency, and OOTI will automatically handle the conversion (USD or EUR).
If there is a variance due to exchange rate fluctuations at the time of payment, you can add a “compensation” payment so that the invoice is marked as paid.
In the project billing schedule:
In project costs:
Cost invoices can be entered in any currency. The conversion is done automatically based on the exchange rate of the day (EUR).
Supplier invoice payments are made in the invoice currency (USD), and OOTI automatically converts the amount into EUR using the invoice exchange rate.
Once the invoice is validated, you can use the grey toggle to switch the currency display (USD or EUR).
In the subcontractor schedule, amounts are expressed in the project currency (USD).
In the project finances:
All figures are expressed in the entity currency (EUR).
Notes:
In the multi-entity group view, the first entity used takes precedence.
Currencies can be set at different levels: project, invoice, client, salaries, contractors, and expense reports.
