Cool looking site + amazing work if you did the entire HR system yourself. As someone who has worked for an "underdog ERP provider" I love every new player in the market. Good luck with sales/customer acquisition and the entire funnel. That's pretty tough if you are alone. From my experience I think a good strategy is hammering the employee self care and privacy hard. I'd also try to attack one niche at a time if possible (even though that's harder for Saas). I'd also play the "we're Australian" angle harder since that's where you can go door to door and get the non website signups. If it wasn't for your wife's accent I wouldn't have known (it's hidden somewhere at the bottom). I understand if you don't want to do that but growing regionally first is a very solid strategy for any type of business software from my experience. The common advice is to hire good salespeople quickly, if you feel you're up to the task I'd say do it yourself. Running a lean/small enterprise software company is pretty doable. Customers will want to hear "your story". Be prepared to offer that, mention that your wife does the audio of the video if you're comfortable with that. That's the stuff that always sold really well. Do not underestimate how many people will try you because they "hate the big companies". If you talk to enough people that work in the broad ERP domain you'll hear all sorts of stuff that isn't really true. Sell features, IT only cares if the stuff improves efficiency etc...I'd say you can safely ignore all of that. Beautiful and UI are (still) vastly underrated, your product is ahead of the curve on the former and I'm assuming also on the latter.
