A practical sequence
- Compare the buying model: individual purchase, sales-assisted B2B deal, subscription or repeat transaction.
- Check market, language, offer, price range and sales cycle. Note which conditions are unknown rather than filling them in.
- Inspect the starting point and included costs. A launch from a small base and a mature program are different settings.
- Ask the agency which part of the process would remain the same and what would need a new test in your context.
Take this into the brief
Case condition / Our condition / Match or gap / Why it matters / New test required
The decision to take away
Choose an agency for a defensible process and relevant experience, not a promise to reproduce another client’s percentage.
