Entering a rent concession

It's great to see you here in the Community, Halie. 

I understand the importance of creating accurate records necessary for your business. I would be happy to assist you through the proper steps.

First, you will want to create a non-inventory or a service item:

1. From the Sales tab, select Products & services.
2. Click the New button.
3. Select Non-inventory and name it "Rent concession" or whatever is appropriate.
4.  Select Save and Close.

Once done, you can record an invoice for your tenant's rent including the rent concession:

1. Select your tenant's name.
2. Under Products and Services, select the standard item and enter the monthly rental fee.
3. On the second line, select the item (rent concession) that you just created. 
4. Make sure to add a negative sign in front of the amount for the "rent concession" item under the Amount column to indicate that it should be deducted.
5. Select Save.

You can create a credit memo for the amount of the concession and apply that to the invoice along with the tenant payment to equal the full amount of rent due or, as mentioned, add the concession to the invoice as a negative amount to reduce the amount due.  Either way will work.
