Cross-brand post-purchase upsells: 13-20% conversion, +$1-$5/order
Commentary byLiftArchiveOur analysis, not theirsGOAT Foods began offering products from its other snack brands after checkout, and core post-purchase funnels converted at 13-20%, adding $1-$5 per order.
The GOAT Foods team made the changes, which were published as an AfterSell case study.
It was a switch to a new app plus new offers, measured over six months, not a single split test.
- Post-purchase conversion: 13-20% on core funnels.
- Revenue per order: up $1-$5 depending on the store. The source also reports a 25-50% rise in revenue per order.
- Cart cross-brand upsells converted at 8-12%.
- 30-40% of orders included at least one upsell. All figures are ranges over six months, with no baseline split.
The change
Post-purchase offer switches to a sister brand's snack

Control
GOAT Foods used a previous upsell platform. Cross-selling between its eight snack brands was limited and hard to track.
Variant
Post-purchase funnels offered items from sister brands, such as caramels to licorice buyers. Cross-brand upsells were also added to the cart.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Snacks are cheap and low-risk to try, so adding a sister brand's product is an easy yes.
- Offering a related treat (pretzels to chocolate buyers) feels relevant without repeating the same item.
- Targeting by cart contents kept offers matched to what each buyer chose.
- Better analytics let the team test and drop weak offers faster.
Caveats: This is a before/after result that bundles a new app, new offers and cart upsells, so no single change gets the credit. Results are ranges over six months, and it is vendor-published.

How to run this test on your store
- Hypothesis
- If we offer a sister brand's product after checkout instead of only same-brand items, then more buyers will add it because a new but related treat is low risk.
- Primary metric
- Revenue per order
- Guardrails
- Post-purchase offer conversion rate
- Refund rate on upsell items
- Repeat purchase rate per brand
- Who should test it
- Multi-brand or multi-line stores with low-priced, related products. It fits less well for single-product brands with nothing related to offer.
Questions
What is a cross-brand upsell?
It offers a product from another brand you own to someone buying from one of your brands.
GOAT Foods offered caramels to licorice buyers, for example.
Do post-purchase upsells hurt checkout conversion?
They appear after payment, so they can't block the first order.
Watch refunds and repeat rates to check the experience holds up.
How much can post-purchase upsells add per order?
GOAT Foods reported $1-$5 per order on low-priced snacks.
Results depend heavily on price point and offer fit.
