I have never been a fan of these sites (Living Social, Groupon etc). First of all you have to discount your service, usually by at least 40-50%, so right off the bat your $100 service is only selling for $50. then on top of that the site takes a percentage (40-50%) so in reality you are doing the job for 1/4 of the price. I'm sorry, but for a service job that doesn't make much sense to me at all. People will talk about upsells and so on, but you can't count on them, and thinking you MIGHT get upsells doesn't pay the bills last time I checked. Here is some quick math:
Let’s say you are selling a $100 wash and wax for $50, so you are actually getting $25 after all the fees. You are going to make a total of $15000.00. That sounds awesome at first, however.... If you work 6 days a week you can knock out 2-3 a day (you're not doing more and doing them right) you are talking about taking 200-300 days to finish, that’s almost a year, and doesn't even take into account paying for supplies, electricity, water, rent, or helpers if you have any. So in essence you are taking a year of work and only making $15000 minus expenses, which comes out to about $7.5 an hour on the high side. Doesn't make much sense to me.
On the other hand if you are a high volume shop you would make the same amount of money, but you would have to pay helpers to get them all done. It would take far less time, but you would be left with far less profit after it’s all said and done. All in all I think that those sites are great for the customer, and great for a company that sells a product, but for a service like detailing, I just don’t think it makes sense.
Now, if you scale it back a bunch to say $25-50, it can be a good way to get customers in the door. However, I have looked into both of the most popular sites, and in my area they would not allow me to set a deal for less than 500 units. It just isn’t worth it.
