I realise that you might have the best of intentions. However, there are many tried and tested tools and services that have been around for a long time. Some hosts swear by some, whereas others wouldn’t touch them with a bargepole, All hosts are different and there’s no ‘one size fits all’ answer.
You can find out a great deal about the challenges hosts face by taking time (probably weeks!) to read this forum.
To be honest, there are regular posts here from people who have just joined the forum wanting to know how they ‘could perhaps develop an offering to help them save time, save money, increase revenue, increase occupancy rates, increase average ratings’. It’s a sort of ‘yawn’ thing - we’ve read it all before.
There’s one huge difference between this forum and others that you’ll find online. We are mostly composed of members who have been hosting for a long time and are wary of new members who want to ‘help’ us. Our collective experience is huge.
Develop your service first after intensive research. Only then should you post here, maybe for beta testers or with a free one-year trial.
To be brutally honest, this forum doesn’t exist to help you develop a product.
It seems that you are putting the cart before the horse. I understand ‘find out what people want and build a product to solve their problems’ but you really have to be more innovative yourself.
