If your church is receiving gifts in kind, you can record them in your accounting by adding a $0 Income transaction to the relevant Financial Account. You can use the transaction notes or memo section to record any details.
Please keep in mind; however, that if your church receives such gifts often and/or their value is significant, you may need to record their market value instead of $0. Please consider consulting a professional accountant for advice on the legislation that applies to your church.
