You Haven't Set Up MePay Yet
Before you can automate your payments, you need to set up MePay first.
Please see Setup And Verify MePay | Web Access (Tenant) for steps.
No Option To Set Up MePay
If you are unable to find the option to set up MePay, it is likely because your Property Manager has not enabled MePay for your tenancy.
Please contact your Property Manager for further assistance or an alternative payment method.
You Are Part Of A Shared Tenancy
While the MePay functionality allows each tenant to set it up with their bank account, the automation feature is designed to only use the account of the tenant who set it up. This means that when rent is due to be withdrawn, the entire amount due will be withdrawn from a single account.
Please see Automating MePay Payments In A Shared Tenancy | Web Access (Tenant) for more information and methods for working around this.
