Our fee structure varies depending on the project and our relationship with the client. For longer term projects we charge monthly retainers, and for ongoing engagements (for eg with M&A advisory firms) we charge either a fixed fee or an hourly rate per project. The actual fee depends on the number of analysts working with you.
There is no minimum tenure as such but we do like to sign a contract and fix a contract term.
It depends on the nature and complexity of the project and of course what the client wants. Usually it's a team of experts working on a project but for a project with fixed deliverables, we usually assign a dedicated analyst to the client.
