I'm an app developer and I've recently developed an ecommerce smartphone app which I plan to sell to business owners with an existing online store because my app integrates with any ecommerce website.

So anyways, I connected with the Ecommerce Manager of a very large suitcases & travel bag retailer on LinkedIn. He seems genuinely interested in having the application implemented for his company and is interested in seeing a demo. We set up a meeting so I could present the demo to him next week.

Luckily for me, I had already developed a demo of the application to show to potential customers but aside from showcasing the application to him, I want to be as prepared as possible.

This is my first time showcasing my application to a client and I'm not sure what kinds of questions to expect. I know of the various benefits that having an ecommerce application can bring, such as increased customer retention due to the level of engagement that smartphone applications bring.

What else can I do to be prepared? Should I also mention potential marketing strategies for the app? I'm only a software developer so I don't know anything about marketing.

Does anyone have experience with presenting apps? Any advice would be helpful. Thanks in advance.
