Why post-purchase
Nothing here can cost you the order.
- Paid first.
The order is complete before the offer appears.
- One tap.
Shopify charges the card on file. No form, no re-entry.
- Once.
Accept or decline, the shopper moves on. Never asked twice.
Three surfaces, one funnel
When to use post-purchase, and when not to.
Oak makes offers in three places. Post-purchase has the most attention and the least risk, so it suits a product the shopper didn't come for.
| Checkout | Post-purchase | Thank-you | |
|---|---|---|---|
| When | Before the shopper pays | Right after payment, before the confirmation | On the confirmation page |
| Payment | Same transaction | Charged to the same card, no re-entry | A separate, new order |
| Best for | Things that belong in the box | A second product they didn't come for, with a real discount | A last, low-pressure nudge |
| Risk | Sits in the payment path | None to the original order | None. It's a new order |
Turn each surface on or off per funnel. Use one, two, or all three.
In practice
Three funnels stores set up first.
Each one is a trigger, an offer, and the post-purchase seat switched on. About two minutes apiece.
