Uppersell & Neddersell

Upsells och downsells låter dig erbjuda ytterligare produkter eller abonnemangsförändringar till kunder med deras sparade betalningsmetoder. Detta möjliggör köp med ett klick som hoppar över betalningsinsamling, vilket dramatiskt förbättrar konverteringsgraden.

Post-Purchase Upsells

Erbjud kompletterande produkter direkt efter kassan med ett klick för att köpa.

Subscription Upgrades

Flytta kunder till högre nivåer med automatisk proration och omedelbar fakturering.

Cross-Sells

Lägg till relaterade produkter till befintliga kunder utan att återigen ange betalningsuppgifter.

Översikt

Uppersell och neddersell är kraftfulla strategier för intäktsoptimering:

Uppersell: Erbjud en produkt eller uppgradering med högre värde (t.ex. Pro-plan istället för Basic)
Neddersell: Erbjud ett alternativ med lägre pris när en kund avböjer eller nedgraderas
Korsförsäljning: Föreslå kompletterande produkter (t.ex. tillägg, relaterade artiklar)

Dodo Payments möjliggör dessa flöden genom payment_method_id-parametern, som låter dig debitera en kunds sparade betalningsmetod utan att kräva att de anger kortuppgifter igen.

Nyckelfördelar

Fördel	Effekt
Köp med ett klick	Hoppa över betalningsformuläret helt för återkommande kunder
Högre konvertering	Minska friktionen i beslutsmomentet
Omedelbar behandling	Debiteringar sker omedelbart med `confirm: true`
Sömlös användarupplevelse	Kunder stannar kvar i din app under hela flödet

Hur det fungerar

Förutsättningar

Innan du implementerar uppersell och neddersell, se till att du har:

Customer with Saved Payment Method

Kunder måste ha genomfört minst ett köp. Betalningsmetoder sparas automatiskt när kunder genomför kassan.

Products Configured

Skapa dina upsell-produkter i Dodo Payments-instrumentpanelen. Dessa kan vara engångsbetalningar, prenumerationer eller tillägg.

Webhook Endpoint

Ställ in webhookar för att hantera payment.succeeded, payment.failed och subscription.plan_changed-händelser.

Hämta kundbetalningsmetoder

Innan du erbjuder en uppersell, hämta kundens sparade betalningsmetoder:

TypeScript
Python
Go

import DodoPayments from 'dodopayments';

const client = new DodoPayments({
  bearerToken: process.env.DODO_PAYMENTS_API_KEY,
  environment: 'live_mode',
});

async function getPaymentMethods(customerId: string) {
  const paymentMethods = await client.customers.listPaymentMethods(customerId);
  
  // Returns array of saved payment methods
  // Each has: payment_method_id, type, card (last4, brand, exp_month, exp_year)
  return paymentMethods;
}

// Example usage
const methods = await getPaymentMethods('cus_123');
console.log('Available payment methods:', methods);

// Use the first available method for upsell
const primaryMethod = methods[0]?.payment_method_id;

import os
from dodopayments import DodoPayments

client = DodoPayments(
    bearer_token=os.environ.get("DODO_PAYMENTS_API_KEY"),
    environment="live_mode",
)

def get_payment_methods(customer_id: str):
    payment_methods = client.customers.list_payment_methods(customer_id)
    
    # Returns list of saved payment methods
    # Each has: payment_method_id, type, card (last4, brand, exp_month, exp_year)
    return payment_methods

# Example usage
methods = get_payment_methods("cus_123")
print("Available payment methods:", methods)

# Use the first available method for upsell
primary_method = methods[0].payment_method_id if methods else None

package main

import (
    "context"
    "fmt"
    "github.com/dodopayments/dodopayments-go"
    "github.com/dodopayments/dodopayments-go/option"
)

func getPaymentMethods(customerID string) ([]dodopayments.PaymentMethod, error) {
    client := dodopayments.NewClient(
        option.WithBearerToken(os.Getenv("DODO_PAYMENTS_API_KEY")),
    )
    
    methods, err := client.Customers.ListPaymentMethods(
        context.TODO(),
        customerID,
    )
    if err != nil {
        return nil, err
    }
    
    return methods, nil
}

func main() {
    methods, err := getPaymentMethods("cus_123")
    if err != nil {
        panic(err)
    }
    
    fmt.Println("Available payment methods:", methods)
    
    // Use the first available method for upsell
    if len(methods) > 0 {
        primaryMethod := methods[0].PaymentMethodID
        fmt.Println("Primary method:", primaryMethod)
    }
}

Betalningsmetoder sparas automatiskt när kunder slutför köpet. Du behöver inte spara dem uttryckligen.

Engångsupersell efter köp

Erbjud ytterligare produkter omedelbart efter ett lyckat köp. Kunden kan godkänna med ett enda klick eftersom deras betalningsmetod redan är sparad.

När du använder payment_method_id måste du ange confirm: true och tillhandahålla en befintlig customer_id. Betalningsmetoden måste tillhöra den kunden.

Uppgraderingar av abonnemang

Flytta kunder till abonnemangsplaner av högre nivå med automatisk proration.

Förhandsgranska innan du åtar dig

Förhandsgranska alltid planändringar för att visa kunder exakt vad de kommer att debiteras:

  });

  return {
    immediateCharge: preview.immediate_charge?.summary,
    newPlan: preview.new_plan,
    effectiveDate: preview.effective_date
  };
}

// Show customer the charge before confirming
const preview = await previewUpgrade('sub_123', 'prod_pro_plan');
console.log(`Upgrade will charge: ${preview.immediateCharge}`);

def preview_upgrade(subscription_id: str, new_product_id: str):

Prorateringslägen

Välj hur kunder debiteras vid uppgradering:

Läge	Beteende	Bäst för
`difference_immediately`	Debiterar prisdifferensen omedelbart ( $30→$ 80 = $50)	Enkla uppgraderingar
`prorated_immediately`	Debiterar baserat på återstående tid i faktureringscykeln	Rättvis tidsbaserad fakturering
`full_immediately`	Debiterar hela priset för det nya abonnemanget, ignorerar återstående tid	Faktureringscykeln återställs

Använd difference_immediately för tydliga uppgraderingsflöden. Använd prorated_immediately när du vill ta hänsyn till oanvänd tid på det nuvarande abonnemanget.

Korsförsäljning

Lägg till kompletterande produkter för befintliga kunder utan att behöva ange betalningsuppgifter igen.

Nedgradering av abonnemang

När kunder vill flytta till en plan av lägre nivå, hantera övergången smidigt med automatisk kredit.

Hur nedgraderingar fungerar

Kunder begär nedgradering (Pro → Basic)
Systemet beräknar återstående värde på aktuell plan
Kredit läggs till abonnemanget för framtida förnyelser
Kunden flyttas omedelbart till den nya planen

TypeScript
Python
Go

async function downgradeSubscription(
  subscriptionId: string,
  newProductId: string

  // Preview the downgrade first
  const preview = await client.subscriptions.previewChangePlan(subscriptionId, {
    product_id: newProductId,

    proration_billing_mode: 'difference_immediately'
  });

  console.log('Credit to be applied:', preview.credit_amount);

  // Execute the downgrade

Bästa metoder

Time Your Upsells Strategically

Den bästa tiden att erbjuda en upsell är omedelbart efter ett lyckat köp när kunderna är i köpläge. Andra effektiva tillfällen:

Efter användningsmilstolpar för funktioner
När abonnemangsgränser närmar sig
Vid avslutning av onboarding

Validate Payment Method Eligibility

Innan du försöker ta ut en avgift med ett klick, verifiera betalningsmetoden:

Är kompatibel med produktens valuta
Har inte gått ut
Tillhör kunden

API:t kommer att validera detta, men att kontrollera proaktivt förbättrar användarupplevelsen.

Handle Failures Gracefully

När avgifter med ett klick misslyckas:

Gå tillbaka till standardkassaflödet
Meddela kunden med tydlig kommunikation
Erbjud att uppdatera betalningsmetoden
Försök inte upprepade gånger misslyckade avgifter

Provide Clear Value Proposition

Upsells konverterar bättre när kunder förstår värdet:

Visa vad de får jämfört med nuvarande abonnemang
Lyft fram prisdifferensen, inte totalpriset
Använd socialt bevis (t.ex. “Mest populära uppgradering”)

Respect Customer Choice

Ge alltid ett enkelt sätt att tacka nej
Visa inte samma upsell upprepade gånger efter att den avvisats
Spåra och analysera vilka upsells som konverterar för att optimera erbjudandena

Webhooks för övervakning

Spåra dessa webhook-händelser för uppersell och nedgradering flöden:

Händelse	Utlösare	Åtgärd
`payment.succeeded`	Betalning för upsell/cross-sell slutförd	Leverera produkt, uppdatera åtkomst
`payment.failed`	Avgift med ett klick misslyckades	Visa fel, erbjud försök igen eller fallback
`subscription.plan_changed`	Uppgradering/nedgradering slutförd	Uppdatera funktioner, skicka bekräftelse
`subscription.active`	Prenumeration återaktiverad efter abonnemangsändring	Ge åtkomst till ny nivå
