You will need to buy the Pro version if you plan on using client/server. If using CWP or IWP then you can just use Server/Server Advanced. However you will still need one copy of Pro / Pro Advanced to help develop.
Well I have 10 users and they want to work remotely. So I was thinking that only the server edition will be enough but thats not true?
I'm new with filemaker so, if you guys have a possible solution.
FileMaker offers bundle packs as promos sometimes. Here is one that they have now.
