Let me explain my product - I currently own a service based company in the disability accommodations field - we coordinate services like sign language interpreters, real-time captioning, captioned media, accessible format books, etc
Initially, the SAAS will at first just be for internal use - scheduling software that can will manage all of the bits of information specific to our field, plus sync with QB for invoicing client, allow contract providers to create and submit invoices, approve provider invoices, track payment, etc.All of these exist in some form in the world, but not in the way that works for our business.
This becomes a income stream when it is licensed to our current customers - coordinators at colleges and universities all over the US and Canada. This would be a money maker all on it's own. In fact, I have a friendly competitor who I know is developing this type of software as we speak.
One thing that will make our SAAS really stand out is to have it sync with the current software they use to track accommodations - they get student requests for services and they either direct hire staff, or contract it out.
Many services are provided remotely. The second thing that would make this stand out is if it also allowed the schools to push their requests out to a marketplace where they either get a bid, or their preferred provider was automatically or manually sent the request through the accommodation management system they already use.
This second part - syncing with the disability management software and the marketplace do not exist any where yet. Having a scheduling software that they could use in this way would be a big step forward for the coordinators who have to wrestle to manage this information everyday.
One thing in my favor is that I know the developers of one of the most popular accommodations software systems being used and we've talked over the years about this idea. He thinks it is a good idea, but has no time to develop it outside of what they already are doing.
I am clear about what my product needs to be able to do, and how it should work - I just have no programming experience. I have held off on this because I don't want to hire a programmer, get 50k into the project and have nothing to show for it. I have heard that story too many time. I'd rather it not be me. :-)
