I don't use budgeted outgoings. Tenant pays invoices when received every quarter eg council rates, water etc. Our % management fee is chargeable to tenants calculated each month on all monies invoiced for rent Inc. outs therefore our fee varies every month. Currently after many attempts with trainers the only workaround is I have to manually work out every month for every tenant my % management fee due on monies to be invoiced that month then add it to each tenancy's invoice before it is sent out. Very time consuming please help?
