This is a book series. A group of teenagers, some boys and girls form an agency/ group for doing odd jobs around their town. They advertise their group and and they share the job offers they got among them. And solve mysteries which came in some jobs. I have read two/ three books in the series and each were from the perspective of a different person in the group. I think the name of their group is something with .inc in it, but I am not sure.
I read these books in 2009/ 2010 in my school library (Sri Lanka)

I think you're talking about the Teen Power Inc. series by Emily Rodda. The series is now known as "Raven Hill Mysteries", but the original ones are still listed as Teenage Power Inc. here on goodreads.
