Can your application consume commercially available services like those from the USPS. Do you support multiple applications that need to share access to closely managed data. Do you need to interface to supplier and cusotmer data? If the answers are yes you may be a prime candidate for web services.
Most sites have one of these pages. The viewer asks a question online that is forwarded via email to the site manager. So far so good. But what happens if the manager doesn't answer. Is there a reminder? An escalation if too much time passes?
If you don't answer their inquiries, customers will think you are not serious. They'll assume the site is inactive.
ConsenCIS includes database tracking of all inquiries. We treat each inquiry as a request and track it to resolution just like we would a sale. Requests can be assigned to specific employees and action items with tickler file entries setup to make sure the followup happens.
