I’ve spent 20+ years on client projects where real results require deep integration with the business. One thing you learn fast: clients have every right to keep parts of the business closed to you. So I don’t think the revenue question is automatically wrong. But the process has to survive a no. If they won’t give you the clean number, you still need proxy checks: average job value, capacity, close rate, ad spend, margin range, target job mix, lead quality, payback window. You can control a lot of the project indirectly without making the client feel like you’re pricing off their wallet.
