About the Extension

Turn the order confirmation page into your best-converting placement

The moment right after a completed purchase is the highest-trust moment in your shop. Post-Purchase Upsell shows your customer one perfectly timed additional offer on the order confirmation (finish) page – and adds it to the existing order with a single click. No second checkout, no second order: one parcel, one invoice, one shipping cost.

Works where other upsell tools stop: unpaid payment methods

Upsells are not limited to card or wallet payments. Orders placed with invoice purchase, prepayment or cash on delivery can be extended with one click – the open payment simply covers the new total. For PayPal orders with an active vaulting agreement, the price difference is charged automatically in the background (official SwagPayPal integration required) – a true one-click purchase without re-entering any payment data.

Full control over what is offered

Campaigns with product selection, optional discount, priority, validity period and sales channel scoping
Offer products via manual selection, dynamic product streams, or automatically by matching category, properties and best sellers
Visibility conditions via the Shopware Rule Builder (cart value, customer group, payment method …)
Configurable offer window (3–120 minutes) with a live countdown on the confirmation page
Shows up to 5 offers in a slider – a single offer keeps the focused one-product view

Built for real merchant processes

Own flow triggers ("Upsell window closed", "Upsell accepted", "Upsell declined") let you delay invoice creation, ERP export or the order confirmation mail until the order is final
Order tag for ERP systems that filter exports without flows (e.g. warehouse/merchandise management)
"Order updated" mail template included
Legally compliant checkout button and equal-weight decline option (§312j BGB)
Analytics dashboard: impressions, conversions and upsell revenue of the last 30 days
Works for guest orders; storefront stays fast (no external scripts, no layout shift)
One-click upsell charges for Mollie payments (mandate-based, requires the official Mollie plugin)

External services

This extension makes no external calls by itself and sends no data to the manufacturer. Only the optional one-click payment features communicate with your payment provider: PayPal – exclusively through the official PayPal extension (SwagPayPal) and your existing PayPal credentials – and Mollie – exclusively via the official Mollie Payments extension's credentials and the Mollie API (mandate check and charge).

Will invoices or ERP exports break?

No. The extension ships its own flow triggers (e.g. "Upsell window closed") and an order tag so invoice creation and exports run only once the order is final. The configuration page contains a checklist with a direct link to the Flow Builder.

Is the offer legally compliant (Germany)?

The offer UI follows §312j BGB – unambiguous order-button wording, consent checkbox, equal-weight decline option, price incl. VAT and revocation note. The price pinned at display time is charged unchanged.

Does the extension work without PayPal or Mollie?

Yes. Orders with an open payment (invoice, prepayment, cash on delivery) are extended without any charge call – the open payment covers the new total. PayPal/Mollie are only needed for the optional one-click delta charge.
