If you have already added your tenant(s) to Innago, your tenant(s) will only see the next month’s invoice in their Innago account. Whenever an invoice is paid, the next month’s invoice will appear. So, if your tenant(s) wants to pay for three months, they could pay for this month, then next month will appear. They can then pay for that one and then the next will appear, etc.
Note: The only exception to this is if you have turned off the ability for tenants to make future payments from your Settings page. In this case, tenants will only be able to pay current (due within 30 days) and past invoices.
