SIS vs. marketing agency

Summit Intake Systems vs. hiring a full-service marketing agency.

An agency runs your ads. SIS runs your intake. The two jobs look similar from the outside; they're not. The agency that's good at the first is rarely good at the second, and vice versa.

Every service business needs both. Someone has to drive leads to the top of the funnel (ads, SEO, content, social) and someone has to convert them at the bottom (intake, booking, follow-up, no-show recovery). Most agencies sell the first half. A growing handful claim to sell both. Almost none execute both well, because the skill sets are different and the tooling is different.

Agencies live in Google Ads, Meta, GA4, and the creative pipeline. They optimize cost per lead, CTR, and ROAS. SIS lives in the CRM, the phone system, the booking calendar, and the SMS layer. We optimize speed to first touch, qualification rate, booking rate, and revenue per lead recovered. Those are different daily jobs done by different daily people.

When an agency tells you they 'do intake too', what usually happens: they build you a GoHighLevel account, set up a couple of templates, run it for a quarter, and then quietly hand it back to you because their team's bonus structure is tied to ad spend, not booking rate. The intake build dies of neglect. We've cleaned up that exact situation a few dozen times.

Side by side

The 10-dimension read.

Where each option actually lands when you score it against the things that move the needle for a service business.

Dimension
Summit Intake Systems
Full-service marketing agency
What they own
Lead intake, automation, and the booking layer end-to-end.
Ad accounts, creative, landing pages, top-of-funnel reporting.
How they measure success
Recovered revenue, booking rate, after-hours capture.
Cost per lead, CTR, ROAS, impression share.
Who builds the workflows
Drew and a small team. Same person every month.
Usually a junior ops person, often offshored, often changes mid-engagement.
Cost structure
Flat monthly per system; tied to the install.
Retainer + ad spend percentage (often 10–20%); aligned with bigger ad budgets.
Time to launch
Typically 5–10 business days for a Money Machine install.
30–90 days to onboard, audit, and launch creative.
Conflict of interest
We make more when your installs work, full stop.
Bigger ad budgets earn the agency more. Fixing intake reduces the need to spend more.
Reporting
Live dashboard with calls, bookings, recovered revenue.
Monthly slide deck with impressions, clicks, and CPL.
Custom builds
Lane 3 work tuned to your business.
Mostly template-driven. Custom work is billed separately and often outsourced.
Hidden costs
Standard SMS/voice usage included.
Ad spend; landing page hosting; tracking pixels; creative revisions; lead routing tools.
Best at
Closing the loop on leads after they exist.
Creating leads that don't exist yet.
Honest fit
Pair us with a good agency — this is not either/or.
Pair them with us — their CPL drops when our booking rate goes up.
When marketing agency is the right call

marketing agency wins when the math doesn't favor automation.

You don't have a lead-flow problem — you have a top-of-funnel problem. If your inbound volume is too low to begin with, intake automation isn't the bottleneck. A good ad agency or SEO firm is the right first hire. SIS pays back fastest when there are already leads to recover.

You want one vendor relationship for everything marketing. Some operators — especially smaller ones — genuinely prefer one neck to wring and don't mind that the intake layer is mediocre as long as the ad reporting is clean. That's a real preference and we respect it. SIS adds a vendor; we don't pretend otherwise.

You're early enough that ad creative is the difference. First two years of a service business, where the brand is barely formed and the offer hasn't found its footing, an agency that can ship 30 creative variations a quarter beats an intake optimization any day. Come back to us when the offer is locked and the leads are flowing.

When SIS is the right call

SIS wins when the leak is bigger than a phone call.

You're already running ads (or paying an agency to) and you can see a delta between leads generated and leads booked. That gap is the SIS install.

You've burned $50k+/year on ads for 2+ years and your booking rate has barely moved. Different problem than CPL; this is intake.

You want your agency to keep doing what they're good at — and have a second team whose entire job is making sure the leads they generate actually convert.

You're tired of the agency saying 'the leads are bad' and your sales team saying 'the leads are slow'. The truth is usually 'the intake is broken'. SIS gives both teams the same dashboard to argue against.

Math check on most of our clients: SIS install recovers more revenue than it costs within 60 days, mostly by closing the gap between leads-generated and leads-booked. That's a number you can stack alongside whatever your agency reports.
