The highest-intent moment in your funnel is the 60 seconds after a customer pays.
The customer already bought.
Payment went through.
The CAC is already paid.
Then plenty of stores send them to a bare confirmation screen and call the funnel finished.
Right now, that customer is in the most receptive state they will ever be in as a buyer. Price sensitivity is at its floor. Purchase anxiety is gone. The decision is made.
Every accepted post-purchase offer is near-pure contribution margin. No new traffic. No additional CAC. Direct revenue lift on an order you already closed.
Open your store, place a test order, and look at what the customer sees in the 60 seconds after payment.
Visa's chargeback threshold dropped in April. Two months in, the brands that didn't react are the ones getting flagged.
The VAMP merchant threshold fell to 1.5%, down from 2.2%. A ~32% cut with no warning tier. If your ratio was sitting in the high 1s last year, you didn't get safer, the line just moved under you.
The trap is how the number is built. VAMP rolls fraud reports and disputes into one ratio, so a single friendly-fraud chargeback (customer got the product, disputed anyway) counts against you twice.
The most exposed brands are the ones with loyal-looking customers quietly disputing legit orders and nobody watching the ratio.
By now, crossing it means per-dispute fines, cash held in reserve, a steeper cut on every transaction, and a processor that starts treating your account as a risk.
The disputed orders were never the real cost. Your ability to keep processing is.
The only lever I'd bet on is winning disputes at scale, which manual ops can't sustain.
Chargeflow handles the full lifecycle for you: two-click integration, no internal ops, and you pay only when they recover ($0 if they lose).

Why Post-Purchase Is the Cheapest Revenue You Have
The structural advantage isn't just intent. It's that a post-purchase offer carries zero risk to your primary conversion.
An in-checkout interruption competes with the sale. It adds friction inside the conversion path, which is why in-cart offers need to stay light.
Post-purchase offers have no such constraint. The payment is already captured. You can make a real offer without risking the order.
A 2023 vendor report found the average one-click post-purchase offer converts at 4.7%, with top offers reaching 28.3%. Thank-you-page offers averaged 1.7%.
The same report found average AOV uplift of 5.6%, with top stores driving 12.7% of total revenue through post-purchase placements.
These are directional figures based on app telemetry, not independent research. What matters is your own AOV-with vs. AOV-without measurement over 14 days.
Confirm whether anything runs post-purchase today.
If the answer is "just the order confirmation," you have unbuilt revenue.
The Three Placements, and What Each Is For
Three places an offer can live. Each has a different job.
- Order bump (in-cart, pre-purchase): A checkbox add-on before payment. High visibility, but it sits inside the conversion path.
Keep it light. Use this only for ultra-low-priced, obvious add-ons where saying yes feels frictionless.
- One-click post-purchase (after payment, before thank-you page): The customer pays, sees your offer, and accepts with one tap. No re-entry of card details.
This is the flagship placement. Zero risk to primary conversion. The charge processes instantly.
- Thank-you-page offer: Lowest pressure, lowest conversion. Useful as a second offer or as coverage for express-checkout buyers who bypassed the post-purchase step.
One setup note: Checkout Extensibility controls where in-checkout blocks can live on Shopify. Non-Plus stores have less flexibility inside the checkout itself, which makes the post-purchase and thank-you slots more important to build first.
Pick one placement. Default to one-click post-purchase.
How to Design the Offer
The app gets you the placement. The offer earns the revenue.
- Relevant and complementary. Not a random catalog item. The offer should feel like the natural next step from what they just bought.
- Priced low relative to cart value. A commonly-used operator reference is keeping the upsell under 30% of cart total. This is a heuristic, not a platform rule. It works because the customer's mental accounting is still anchored to the original purchase, and a significantly larger ask breaks the frame.
- For consumables, lead with refill or upgrade. A customer who just bought a 30-day supply is the most qualified person in the world to buy a 90-day supply right now. Convenience framing beats discount framing: "add this while your order is still processing" outperforms a percentage-off push as the lead mechanic.
- Build a downsell. If the first offer is declined, a lower-priced alternate recovers a second slice of acceptance. Don't let a single decline end the sequence.
Write one relevant, sub-30%-of-cart offer for your single best-selling product.
The Margin Math That Decides the Offer
Raw acceptance rate is not the metric that decides which offer to run. Incremental contribution is.
Acceptance rate x contribution margin per upsell x monthly order volume = incremental contribution
A worked example using hypothetical numbers anchored to a late-2024 Shopify AOV baseline of roughly $90 (Red Stag Fulfillment, 2024), at 2,000 orders a month:
Option A: $35 upsell, $28 contribution margin, 6% acceptance rate. 0.06 x $28 x 2,000 = $3,360/month
Option B: $90 upsell, $65 contribution margin, 2% acceptance rate. 0.02 x $65 x 2,000 = $2,600/month
Option A wins by $760 a month without the friction of a larger ask. Run this math on your own numbers before you build anything. The output decides the offer, not the sticker price.
Run the acceptance x margin x volume math before you ship.
