Responsibilities
A scope needs owners and evidence.
Ambest owns the agreed analysis, creative or execution work. The client owns accurate business information, access, factual approval and decisions that only it can authorize. Each milestone should identify what is reviewed, what evidence closes it and what becomes more expensive to change afterward.
Website scale, baseline condition, markets, content or production complexity, internal resources, access, travel, versions and third-party charges can all shape a quotation. No fixed price or quantity is invented here.
