Flat Fee Arrangement

Flat Fee Arrangement

Flat Fee Arrangement

A flat fee covers a specified scope for a fixed price. Scope definition is essential, along with a mechanism addressing work falling outside it and events that materially change the matter.

Fees may be payable at engagement, on milestones, or on completion.

Fixed Fee, Flat Fee

Why it Matters?

Scope creep destroys these arrangements, and the protection is defining not just what is included but what triggers renegotiation: removal, consolidation, addition of parties, or a trial setting. Flat fees work best across a portfolio of similar matters where variance averages out, and poorly on individual cases where a single outlier consumes the margin from many. Clients benefit most from cost certainty on high-volume routine work.
