There is no universal price. Base it on scope, stakeholders, evidence complexity, delivery effort, risk, client size and the commercial importance of the decision. Protect a margin floor and make exclusions explicit.
Use multiple options only when they represent genuinely different scopes or levels of support. Do not create artificial packages just to use an anchoring tactic.
Only deliberately. Trade for reduced scope, faster payment, longer commitment or another meaningful concession rather than reducing price with nothing in return.
Separate it from the diagnostic unless it was explicitly included. Price the production work based on defined scope, technical dependencies, risk, testing, rollout and support.
