ShowMojo's monthly and annual subscription fees are billed a month in advance. But may other add-on services are billed in arrears.

At the end of the billing period ShowMojo calculates applicable charges for additional leads, additional listings, lockbox insurance, Live Answer, and any other add-on service that was used during that billing period. 

This means that even if an account has been closed, a final bill may still be generated for any of these fees.
