The biggest thing to look for is the support: Support in materials you will need to sell your products; support in training you in your craft; support in training, subsequent to your startup, so that you know you can grow as the business theoretically expands. I have been involved in franchise operations that were frankly pretty poor, in that latter area. Any and all new ideas and direction came from the franchisees, not the parent organization.
So, you want to know the business is innovative. Try to talk to as many franshisees that have been there for the longest, as you possibly can; don't just talk to one or two that are recommended by the franchisor. See how the multitude of current people in the operation feel.
Look at news articles. See how the Company is viewed by the public. Look for blogs that complain about the Company. EVERY company is going to get complaints, but the seriousness about the complaints, how they are handled and whether they are repeated over and over again tells you whether the company is listening to the public, or even cares about the negativity. Blogs are great for that.
I actually may have talked to someone from that Company before - or one like it. But it was on a social basis, not a professional one. The one thing I could not tell is whether they send coupons to the phone unsolicited, or whether the phone owner subscribes to the service. Whether or not it is by subscription is key to how it is sold. Are you getting stores and such to sign up for delivering coupons, or are you getting subscriptions? How does the delivery of such coupons affect peoples' phone bills? If they increase the phone charges, then the value of the coupon is diminished, and down the road people will opt out. If it is non-subscription and unsolicited, it will not be long before laws are written to keep that from being allowed. You need to really check that carefullly.
Finally, one of the biggest problems with other, printed coupon scenarios is that you normally have a well defined area that is protected. That is important. But I have heard terrible scenarios where major, perhaps national chains are signed by the parent company, and you get nothing out of it. There are two scenarios where local people actually got a national store interested, but the franchisor took over and the local franshisee still got nothing! If you are protected in all of this, TRUST NO ONE!!!! GET THAT PROTECTION IN WRITING AND HAVE AN ATTORNEY WORK WITH YOU!!!!
I admit to knowing nothing about the technology, so there are a lot of questions I might have. Along with this last topic, if they get enough national chains as clients, and you are not paid on those, is there a chance that your own clients might even get less opportunity to be protrayed on the service? Can corporate accounts smother local accounts? Will a national chain be able to eliminate local competition the way grocery stores with floral shops can tell a landlord not to let any florists into that shopping center? Can this kind of thing limit your income?
My apologies for not knowing more. But I hope some of these questions give you ideas, as you learn more from them.
