Former Droid user new to iPhones, just purchased a 4s for me and a 4 for my wife. I am looking for a way to track calls when they come in the office and enter it into some kind of job/prospect sheet. I would then like to integrate it with QB to run my estimates and invoices. Y'all have any ideas? I basically want to track a call (potential customer) all the way through to (client) -someone who pays for our landscaping services. Gracias.
