I can't say enough good things about Pic-time. If you have to pick something to invest for your photography business, I highly recommend this more than anything I've used.
Everything is so seamless. If I have to pick my most favorite part of its feature is products. The clients can easily access to your photos as well as print and product shops all in one place.
