How to use Agency Client Reporting: The First vs Repeat CM Slide
A ready-to-copy monthly-report slide that turns first-order vs repeat-order contribution margin into a defensible CAC ceiling for next month — with the script agency leads use to walk clients through it.
The First vs Repeat CM Slide
A single monthly-review slide that shows first-order CM, repeat-order CM, the euro delta, and the CAC ceiling those numbers imply for next month.
The First vs Repeat CM slide is a client-facing summary that splits contribution margin by customer cohort — brand-new buyers versus everyone else — and turns the gap into one operational recommendation for the coming month's paid budget. It exists because reporting a blended CM number hides the exact place a DTC brand loses money: the first order. By showing the two lines side by side, the euro delta between them, and the CAC ceiling those numbers imply, the slide converts a technical segmentation into a decision the client can actually approve in the room. It's the anchor slide of a modern DTC monthly review.
Most agency monthly reports still lead with ROAS, revenue, and blended contribution margin. Those numbers look fine right up until the client's bookkeeper asks why the bank balance is going the wrong way.
This slide is the fix. It answers the only question the founder actually cares about: are we making money on new customers, and if not, what do we do about it next month? Everything else in the deck supports this one page.
What actually belongs on the slide
Four numbers, one recommendation. First-order contribution margin per order in euros. Repeat-order contribution margin per order in euros. The delta between them. And a suggested CAC ceiling for the next 30 days derived from those two figures and the client's target payback window.
Everything else — the waterfall of cost components, the vertical benchmark comparison, the cohort trend — belongs in appendix slides. Founders lose attention past the fourth number on a slide, so the appendix is where you park the depth for the CFO to read later.
Frame the delta in absolute euros rather than percentages. A client hearing "repeat CM is 340% higher" nods politely; a client hearing "we make €18 more on every repeat order than every first order" starts doing the mental multiplication against last month's order count on their own.
The one thing to leave off
Don't put blended CM on this slide. It's the number the split exists to replace. If the client insists on seeing it, put it in a corner of the appendix — never next to the two cohort numbers, because side-by-side it always wins on visual weight and the whole insight collapses.
How the slide is built each month
The build is 90% data pull, 10% design. Pull last month's orders tagged by customer order-number-in-lifetime, group into first-order (order_number = 1) and repeat (order_number ≥ 2), and calculate CM per order for each group after COGS, payment fees, shipping, packaging, and returns.
For Shopify clients this can be pulled directly from the admin export plus a spreadsheet — no data team required. Attribute paid acquisition cost only to the first-order cohort; the whole point of the split is that CAC hits new customers, not returning ones.
Example monthly CM per order — apparel client, €80 AOV
The visual above is the shape you're aiming to reproduce for your client each month. The waterfall version — which decomposes each bar into COGS, fees, shipping, and CAC — is a stronger appendix companion and works well as a follow-up when the founder asks "why is the first-order bar negative?"
Benchmarks that give the delta meaning
A €18 delta means nothing on its own. The client wants to know whether their gap is normal, wide, or a red flag. Publish typical ranges by vertical alongside the slide so the number lands with context.
Roughly, apparel and beauty see repeat CM run 2-4× first-order CM at healthy stores. Electronics and consumables sit tighter. Subscription verticals break the split entirely because order 1 and order 2 are often mechanically identical — flag those separately.
Typical first vs repeat CM per order, DTC verticals (€60-€120 AOV band)
| Vertical | First-order CM (€) | Repeat-order CM (€) | Delta (€) | Repeat / First ratio |
|---|---|---|---|---|
| Apparel | -2 to +6 | +18 to +28 | +16 to +26 | 3-5× |
| Beauty & skincare | 0 to +8 | +20 to +32 | +18 to +26 | 3-4× |
| Consumables (food, supplements) | +2 to +10 | +14 to +22 | +10 to +14 | 2-3× |
| Electronics & accessories | +5 to +15 | +16 to +24 | +8 to +12 | 1.5-2× |
| Home & lifestyle | -4 to +4 | +22 to +34 | +22 to +30 | 4-6× |
| Subscription-first | See note | See note | N/A | N/A |
Two client conversations get much easier once these ranges are on the page. Wide-delta verticals (home, apparel) can justify aggressive first-order CAC because repeat margin bails them out; tight-delta verticals (electronics) can't, and pretending otherwise is how agencies lose accounts three months later.
Presenting it — the 90-second script
Read the slide out loud in this order: first-order CM ("we lost €4 on every new customer"), repeat-order CM ("we made €22 on every returning one"), delta in euros, implied CAC ceiling. Then stop talking and let the founder ask the follow-up. They will.
Two objections come up most: "but our repeat CM is great, so we're fine" and "first-order CM just turned positive this month — should we scale?" Both have dedicated follow-on slides in a mature reporting template, and both hinge on repeat rate, not the CM numbers themselves. Show the 12-month repeat rate on the same slide if the client keeps drifting to those questions.
The recommendation line, word for word
"Based on this month's split and your 90-day payback target, we recommend capping blended first-order CAC at €X for the coming 30 days. If we can hold that, contribution stays positive at your current repeat rate. If CAC creeps above €Y, we pause the lowest-performing channel first." — that's the sentence the whole slide exists to earn.
Frequently asked questions
Slide 2 or 3, right after the one-line month summary. It's the anchor slide — every other number in the deck (channel spend, creative performance, funnel CVR) should trace back to whether it moved first-order CM in the right direction. Burying it at slide 15 signals it's not the decision the meeting is about.
Export the last 30 days of orders from Shopify, tag each with the customer's order sequence number (a simple pivot on customer email), and subtract COGS, payment fees, shipping cost, packaging, and expected returns from revenue. Attribute total paid ad spend across the first-order cohort only. The full walkthrough is in our Shopify sourcing guide.
That's the most common client objection, and it's the trap. A €25 repeat CM at a 12% 12-month repeat rate makes the lifetime contribution math worse than a €15 repeat CM at 35%. Always show repeat rate on the same slide, or the client will use repeat CM to justify overspending on first-order CAC.
Take the repeat-order CM, multiply by expected orders-per-customer in your payback window (usually 90 days for DTC), add the first-order gross margin, and that's the max acceptable CAC. Anything below is profitable within the window; anything above defers profit past the payback threshold the client agreed to.
Not cleanly. Subscription verticals have near-identical CM on order 1 and order 2 by design, so the split loses its signal. Replace it with a cohort-retention-curve slide and a per-cohort LTV projection instead — same decision ("is new-customer economics working?") but a different visual.
Yes, and it becomes even more useful. A positive first-order CM is the green light to scale acquisition spend, which is a much bigger decision than pausing it. The slide anchors that scale-up in a specific CAC ceiling instead of a vibes-based "let's push more budget."
Euros. Founders convert percentages into decisions much slower than they convert absolute money. "€18 more per order" multiplied by last month's 800 orders = €14,400 the client can feel. "340% higher" prompts a nod and no action.
Once a quarter is enough. First vs repeat CM benchmarks move slowly because they're structural (unit economics, shipping, returns) rather than performance-driven. Rebuild sooner if the client's AOV band shifts materially or they enter a new vertical.
Presenting it without a recommendation. The slide is not a data dump — it's a decision document. If it doesn't end with a specific CAC ceiling and a specific channel action for next month, the client will thank you for the insight and change nothing.
First-order CM typically compresses further in Q4 as CAC inflates and discount rates rise, while repeat CM stays roughly flat. Flag this on the slide with a small "seasonal expectation" note so a negative-and-widening first-order CM in November doesn't get read as a broken account — it's the market.
