1) It should have many products / services, that offer exceptional value, and which are in demand globally
2) The system should work well to upsell our customers who by the lower priced front-end product/service, with many higher priced products over time, so we earn higher commissions from the same customer
3) We should be paid lifetime commissions on our customers
4) The refund rates should be low
5) The marketing system / tools provided should be good, with high converting sales funnels
6) There should be big ticket or top tier priced products / services offered too, so that we can earn $1000+ or $5000+ commissions per sale
7) There should be a professional phone sales team to follow up with our customers and upsell them to the big ticket or top tier products / services, so that we earn higher commissions, without spending our own time and efforts to make follow up phone calls.
