On the whole, when you look at the amount of money it costs to set up customer service and deal with keeping a site cutting edge, the white label dating services generally offer a great alternative to software.
If someone joins your site as a paying member, they pay a fee.
Well, it's a nice shop, but what's on your shelves. They look at your shelves and see the profiles are covered in cobwebs. They might stick around, and they might even spend one months membership, but in general, they will run quickly once they find your site has no responsive people on it.
They can IM, they can select and gather prospective matches and do a compatibility test... The people you have on your shelves are unresponsive because you stocked your shop with old stock. Consequently, the person who just walked into your shop is not impressed. I recommend starting with a white label dating service.
___In general I recommend against using software for starting a dating service. It may well be possible to get a dating service up and running for under 00, but that's only 1% of your costs.
Then it needs supporting, bug fixes, and most importantly, you need to build the service to critical mass. Someone walks into your freshly built dating shop and they look around.
Although I have not joined datingsitebuilder, and not one of them either, was reading reviews before signing up but realized some of the latest reviews just look like spam. I have paying CUSTOMERS that are getting ready to lose their access because the Dating Site Builder people will not respond to me.
