GOAT 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.

## Result

**13-20% conversion, +$1-$5/order**

- 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.

## 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)

- 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

- 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
- Guardrail: Post-purchase offer conversion rate
- Guardrail: Refund rate on upsell items
- Guardrail: 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.
