We purchased the Teleflora Dove POS about 2 years ago. At that time, our only choices were FTD, Teleflora and one other outside company (I don't remember the name). 800flowers did not have a POS ready and I was not aware of FloristWare nor Flowerchat where I could have asked others. We had demos of FTD and TF in our shop. The FTD had an appearance of an old program that they tried to look updated (just my opinion). The other company kept calling and calling 2 or 3 times a day which gave me the feeling that they were desperate for a sale. Based on a number of things, we decided to go with TF.
We really like our DovePOS. It has really freed up my business partner from having to manually type every sale in (we used to have to hand write everything). Since we are a really small shop, we do not need all their modules. We did, however, purchase the accounting and marketing modules because it was on special for 50% off so we didn't pay retail price for them.
As a small shop, the Dove fits our needs. Does it do everything? No, it doesn't. I think it is because their software designers don't work in retail and have no idea what is really needed and not needed (which I think is the case with alot of systems). For example, it would be great if there was a place that you could enter information on the back of the card and little things like that.
If I were you, I would make a list of all the things you would like your POS system to do for you. Start with what you won't live without and the things you would like it to have but is not necessary. Have demos from everyone that has a POS system (FloristWare, TF, 800flowers, etc), even the companies that have generic ones (not florist specific) like software programs and credit card processors (only the trusted ones!!). Maybe you need the accounting but prefer hand written cards, etc. Every business is different.
After you have done your list, research, and seen demos, then decide what is right for you.
Hope this helps!
