Thank you for response.
At this stage there is only idea, but I want to disclose and discuss it and then
a) implement it
or
b) kill it.
There are many accounting packages, but only few exist on Linux, and almost no professional scale accounting software. I believe, that Lazarus/FP is good tool to develop for multi OS desktop software. Recently (in past year or two) almost all accounting software rapidly moved to cloud and left users with no choice. I am an accountant and I really hate cloud accounting software for many reasons (speed, unpredictable behaviour, pricing policy and data ownership are main of them). Although software developers are pushing users move to cloud, market and users' habit do not change that rapidly and here I see market niche where new product can fit, at least for some time till it will grow into something else.
One of parts of the idea is to commercialise the product and share part of the profit (if there will be any, of course) with FPC/Lazarus community to support development. It is like pair commercial product with open source to produce a bit sustainability.
I am not obsessed with idea, it will be ok if it is killed (I am not developer, I am just a bookkeeper, I do not know all and every aspects). I just want to meet and talk to right people about this.
I am not sure if this is a right place for such discussion, so I am ready to share my contact details (if I am allowed do this here).
I am London based, speak English, Russian, Lithuanian.
Thank you.
