Okay, never mind.
Paula,
If you are going to extend credit to clients- I`d weigh the potential revenue increase against the increased costs which would include:
I don`t know what the "typical" amount involved in an engagement with a client - but consider developing a relationship with a funding source that would deal with all the "stuff" mentioned above - allowing you to benefit from additional clients.
Glad to hear that it helps. Send me a PM or email , if you want to delve into the specifics of your situation.
