# How to add additional rent as a fixed amount in Plexflow

## How to add additional rent as a fixed amount in Plexflow

In some cases, a commercial lease can include a **fixed additional rent** on top of the base rent (e.g. common expenses, shared occupancy, a secondary warehouse).
This section explains how to add it directly in **Plexflow** so that billing is automatically adjusted in future collections.

### Steps

#### Step 1 – Go to Rent Details in question

From the **Rents** section, open the record of the active lease for which you want to add an additional amount.

#### Step 2 – Go to the “Services” tab

Click the **Services** tab.
If no service has been assigned yet, you will see a **“Click here”** link to add one.

#### Step 3 – Choose the service type

In the **Type** section, open the **drop-down menu**.
Select the desired service.
In this example, a service titled “Additional rent” was created beforehand.

#### Step 4 – Complete the fields

Fill in the required fields:

- **Description** (e.g. Extra warehouse, Parking, Internet)
- **Price** (fixed amount of the service)
- **Tax** (choose the applicable tax: **No tax**, **TPS 5%**, **TVQ 9.975%**, or **TPS&TVQ 14.975%**)

### Final result

Once it is saved, the system will automatically adjust the **upcoming collections**, distinguishing the **base rent** from the **additional rent**.
The latter will appear in the invoice details and in the income reports.
