Is it okay for me to propose to my newly bought sub sale low cost apartment to create a software for maintenance and sinking fund fee using online payment? Since they are collecting it manually... so I have the skills to build one. What is the disadvantages if i propose this to them?

If for my own stay I will give it for free for my own coding portfolio. They just need to maintain the hosting, domain, android/ios developer fee only. I think it is viable and more than enough.

But if for other JMB who would like to buy I can give the product with 'one-off' with manuals etc for their own maintenance and future change request because I don't i can commit if there's a lot of buyers since I'm working full time now. The price also is not high compared to existing market. Just for fun and value added portfolio i guess...

Hi, my JMB don't want to do it and they rejected my proposal. I heard from my friend the reason why they rejected it because they are doing money laundering... but got no proof...hence thats why they don't want the system as transparency..
