Affiliate Marketing Secrets

I have a computer business and have been looking into reselling online backup solutions to my customers but I wouldnt make any money at 30% commission becoming an affiliate or reseller partner. So I have been wondering if I can get away by selling it to my customers and getting them to pay me each month for the subscription (higher price) and then I pay the online service the original price and I make margin. Is this possible? The only thing is would the company get suspicious if they saw me paying multiple accounts each month?
