Here is a short, one-page sample concept note
This concept note does a great job summarizing the program into just one page, focusing on the objective and methodology of the project. Additionally, it clearly states the total budget and the amount the NGO is seeking. Stating that 60% of the project costs have been self-funded also adds a plus point as it shows the sustainability of the project and NGO to the donors.
