What if we use platforms beyond Google and Meta?

Doe connects to any ad platform with a spend reporting API (Google, Meta, LinkedIn, TikTok, and more). Each channel gets its own CAC calculation, and Doe normalizes the data so cross-channel comparisons are apples-to-apples.

What if UTM parameters are inconsistent or missing?

Doe uses multiple signals beyond UTMs, including referrer data, landing page patterns, and CRM source fields, to attribute customers. It also flags attribution gaps so you know where your tracking needs improvement.

How does this handle customers who interact with multiple channels?

Multi-touch customers are attributed based on the model you choose. Doe shows you the full journey map and lets you compare how different attribution models assign credit, so you can decide where to shift budget.

Can I see CAC trends over time?

Yes. Each weekly run builds on previous data, so you get trend lines showing how CAC by channel evolves. This helps you spot when a channel is becoming more expensive or when a new campaign is outperforming expectations.

Does Doe calculate LTV:CAC ratio?

Yes. By combining Stripe revenue data with acquisition cost, Doe calculates LTV:CAC ratios by channel and cohort. This reveals which channels bring in the most valuable long-term customers, not only the cheapest acquisitions.

True CAC by channel, no spreadsheet required

Revenue data from Stripe meets marketing spend across every channel, and Doe calculates real customer acquisition cost by channel and campaign. Updated weekly.

How Doe calculates your true CAC

Pulls revenue, subscription tier, and payment dates for new customers

Stripe

Doe collected 47 new customers this week with MRR and payment metadata mapped to each

Pulls ad spend and cost-per-result across all active campaigns

Meta Ads

Doe captured spend, impressions, and conversion counts by campaign and ad set for the same period

Matches each customer to the campaign or touchpoint that acquired them

Doe traced every new customer using UTMs, referrer data, and CRM source fields — Google Search delivers $38 CAC with a 5.2x LTV ratio, while LinkedIn sits at $210 CAC with a 1.1x ratio

Builds the channel-by-channel attribution report with trend lines

Doe compiled spend, CAC, LTV:CAC ratio, and 12-week trend lines showing where acquisition costs are rising fastest

Delivers budget recommendations to your marketing team

Slack

Doe posted the three most efficient channels, flagged LinkedIn for a spend review, and suggested shifting $2K/week to Google organic content

Runs Every Monday at 8:00 AM · Attribution report updated in Google Sheets, key findings posted to #marketing in Slack

You're guessing where your budget should go

Every platform tells you it's working. Google Ads claims 200 conversions. Meta says 180. Your CRM shows 150 new customers. The numbers don't add up because every platform takes credit for the same customer, and nobody's math includes the full picture from first touch to closed revenue.

So you build a spreadsheet. You export spend from each ad platform, pull revenue from Stripe, match customers by UTM parameters (when they're not broken), and try to calculate a real CAC. The formula is fragile, the data is stale by the time you finish, and you're never fully confident in the numbers.
