I would like to develop a project management software with invoice capabilities and crm as well.
It should have:
- Comm system (like slack)
- Invoice like zoho
- Crm like zoho or better
- Project Management like Basecamp or Meistertask
Other smaller features can be developed after main project has been done.
Look and feel is very important. We are open to technology choice.
We would like to understand the methodology of development to be used for my project.
