For each tenancy, choose whether you or the landlord issues the rent documents.

A company landlord issues invoices, a private landlord a monthly rent breakdown instead.
The landlord’s invoices have their own numbering, counted from the start of each year.
Tenants report payment from the link in their payment e-mail; you confirm it or mark it once the landlord confirms.
Your percentage fee also covers this rent; if you hold nothing to deduct it from, the landlord owes it.
