Have you looked at the Invoices Starter Solution?
Yes I found that when I was digging around. I am sorry that I appear to be such a newbie, I have run my company for 30+ years. I bought Filemaker in the past, but now I have to start over. I am convinced it will do what I need, I just need to swallow the price of getting going. I thank you for your patience, and hope to become a real ninja with your stuff.
Well take your time and enjoy relearning Filemaker. Remember it is a database design tool, and you can adapt existing stuff or create things to suit your specific needs. Poke around inside the starter solution and try to understand what is going on—and don't be afraid to come back to this forum with questions as they arise. There are plenty of eager minds here to help the curious.
Welcome back, srlaudio! The Training Series, the Resources (on this forum) and of course this forum is searchable - all will help you get up to speed.
Ask away and there are plenty of us willing to point you in (several, likely) directions.
