Most discovery calls are frustrating because the agency is pitching an average version of their program to an average version of your business. The fastest way to fix that is to walk into the first call with the specific numbers that make your business yours. A specialist will adjust their pitch on the fly; a generalist will default to the deck. That itself is a useful sort.
The eight numbers
1. Average transaction value / case value / patient value. A plumbing shop at $650 average ticket runs a different program than one at $1,400. A personal-injury firm at $25K average case value runs a different program than one at $120K. The economics of every channel recommendation change with this number.
2. Close rate (or conversion rate) from lead to sold. Some shops close 15% of leads; some close 65%. The difference changes cost-per-lead targets by a factor of four. A good agency adjusts budget against close rate.
3. Current monthly marketing spend, by channel. Not just the total — how it's split. If you're 90% Google Ads and 10% SEO today, a migration toward 60/40 is a different conversation than starting from scratch. Shows the agency the starting point.
4. Current monthly lead volume and source attribution. Even rough numbers. "About 120 leads a month, maybe 40% from LSA, 30% from organic, 30% from repeat referrals" is a decent brief. Anything is better than nothing.
5. Service-area footprint. Zip codes, metros, states, country. Pricing and program design change significantly at different footprint sizes, especially for local businesses.
6. Seasonality curve. When does your month look best? When does it look worst? A plumbing shop with a clear winter peak needs a different budget pacing than one with flat demand year-round. Bring a gut-feel curve if you don't have data.
7. Team capacity — phones, intake, calendar. How many jobs or appointments can you actually handle per week? The ceiling is real, and marketing that exceeds the ceiling is wasted. A good agency asks about this early.
8. The business constraint. Where are you stuck? Is it lead volume (can't fill the schedule), lead quality (filling the schedule with the wrong jobs), close rate (filling the schedule with viable jobs but losing them at quote), or fulfillment (closing them but can't keep up)? The agency's recommendation should match the constraint. If it doesn't address your constraint explicitly, you're being pitched the agency's default package.
Why this works
The average discovery call ends with the buyer thinking "they seem smart" and the agency thinking "another warm lead." Neither side has the information needed to decide. When you front-load the numbers, three things happen:
- The agency either rises or falls. Specialists visibly engage with the numbers and start modeling. Generalists hand you a standard deck regardless. This is the fastest way to sort.
- The proposal becomes specific. The agency can build a plan around your actual economics, not around their average client's. You'll get a more realistic estimate of what's possible.
- The sales cycle shortens. You don't need three more calls to get to "what would this actually do for my business." That math happens on call one.
What to do if you don't have the numbers
Most operators don't have all eight. Bring what you have, and flag what you don't. "I don't track close rate by source — what's your usual guess for my vertical?" is a much better conversation than "I don't know." It also reveals how the agency handles information gaps — which is itself a signal worth paying attention to.
