Does rent reporting cost anything?

There is no charge for it.

From the guide Rent-Payment Credit Reporting.

For landlords and managers

On the rent collection screen (website) or under Unpaid rent to confirm and Rent reporting permissions (apps), a landlord or manager decides, property by property, whether residents may choose full payment history, and answers each unpaid month before anything is reported. Allowing it means agreeing to record every payment received outside Seayora within five business days and to tell Seayora at once if rent confirmed as unpaid was in fact received. When a resident paid another way, record it with “Tenant paid me another way” and say how and when it arrived — that is what lets the month count as on time.

To require reporting in every new lease, choose “Require in every lease” for the property and accept the statement shown: every lease from that day carries the addendum, every resident is treated alike, and every payment received outside Seayora is recorded within five business days. “Ask current tenants to sign” sends the addendum to every resident on a lease signed before then; the Rent reporting in leases list shows who signed, who is waiting and who declined, and lets you release anybody.
