To be honest, I'd take a few months off developing nopCommerce the software, and focus on developing nopCommerce the brand.
nopCommerce is a superb piece of engineering. But most everyone I talk to has never heard of it. Either developers in the .net world, or just generally businesses in person. I'm not sure that nopCommerce carries the weight of competing products like osCommerce, wooCommerce, shopify, etc. As a plugin developer for nopCommerce, the number of people using the platform directly has an impact on the sales, so I'd rather see more people using the platform rather than any single given feature.
I'd be thinking about things like:
- modernising nopcommerce.com. This site feels dated (don't hate me!)
- building reputation within the microsoft community, for example, Andrei, are you a Microsoft MVP? You should be.
- Spend some time doing howto videos
- build an appstore for nopcommerce plugins, a central place to buy themes and plugins rather than how fragmented it is now.
- make a big deal out it how successful it is. Maybe start tracking metrics about how many orders have been taken, values, etc. Could that be a condition of using the free version, it anonymously calls home to you?
- get pci accreditation for nopcommerce. It's not on the centralised list of compliant applications, which is a shame.
I really rarely get emails from nopCommerce. You could market to me a lot harder than you do without annoying me.
