Compare relative cost without false precision
Use a comparable scope and explicit unknowns instead of invented price tiers.
Normalize what the price buys
Separate professional fees, media spend, software, production and client time. Match currency, period and tax treatment when real quotations are available. Without comparable current quotes, “cheap” and “premium” are editorial impressions, not established pricing facts.
Expose uncertainty instead of averaging it
An unknown integration cost should remain an unanswered item until estimated. Do not convert it to zero. Ask for a base scope plus conditional additions, with the trigger for each addition. This helps compare proposals even when the final total depends on an audit.
Compare the cost of a usable result
Two retainers may carry different production capacity and client obligations. Identify which parts your team must supply, then assess whether that workload is feasible. Avoid publishing a universal league table of agency prices from a few unrelated examples.
Take this checklist
- Record date, currency, period and included work.
- Keep unknown amounts visibly unknown.
- Separate recurring and one-off costs.
- Compare client workload alongside fees.
