The kit is a collection of ready-to-use templates for business owners who don't have the time or inclination to build a system for themselves, but want to get right to work. It includes solutions for tracking customer and vendor contacts, sales, product information, invoicing and shipping.
Of course, if you want to get in and fiddle with the solutions, that's no problem. You can enter layout mode, tinker with scripts, etc. So not only are they useful out of the gate, but the templates also offer an opportunity to see how a well-made solution is put together.
There's both a Standard Edition of the productivity kit (for companies selling goods) and Service Edition (for companies providing services) available. Both require Filemaker Pro 11. If you don't have it, don't worry. The kit includes a 30 day trial. Have fun and get to work!
