Upsell e Downsell - Dodo Payments Documentation

Upsell e downsell ti permettono di offrire prodotti aggiuntivi o modifiche di piano ai clienti che utilizzano i metodi di pagamento salvati. Ciò consente acquisti con un solo clic che saltano la raccolta del pagamento, migliorando drasticamente i tassi di conversione.

Post-Purchase Upsells

Offri prodotti complementari subito dopo il checkout con acquisti con un solo clic.

Subscription Upgrades

Sposta i clienti su livelli superiori con la proration automatica e la fatturazione immediata.

Cross-Sells

Aggiungi prodotti correlati ai clienti esistenti senza reinserire i dati di pagamento.

Panoramica

Gli upsell e downsell sono potenti strategie di ottimizzazione dei ricavi:

Upsell: Offri un prodotto o un aggiornamento di valore superiore (es. piano Pro invece del piano Basic)
Downsell: Offri un’alternativa a prezzo inferiore quando un cliente rifiuta o downgrade
Cross-sell: Suggerisci prodotti complementari (es. addon, articoli correlati)

Dodo Payments abilita questi flussi tramite il parametro payment_method_id, che ti consente di addebitare il metodo di pagamento salvato del cliente senza richiedere nuovamente i dati della carta.

Vantaggi chiave

Vantaggio	Impatto
Acquisti con un clic	Salta completamente il modulo di pagamento per i clienti di ritorno
Conversioni più alte	Riduci l’attrito nel momento della decisione
Elaborazione istantanea	Gli addebiti vengono elaborati immediatamente con `confirm: true`
Esperienza fluida	I clienti restano nella tua app per tutto il flusso

Come funziona

Requisiti

Prima di implementare upsell e downsell, assicurati di avere:

Customer with Saved Payment Method

I clienti devono aver completato almeno un acquisto. I metodi di pagamento vengono salvati automaticamente quando completano il checkout.

Products Configured

Crea i tuoi prodotti upsell nella dashboard di Dodo Payments. Possono essere pagamenti una tantum, abbonamenti o componenti aggiuntivi.

Webhook Endpoint

Configura webhook per gestire gli eventi payment.succeeded, payment.failed e subscription.plan_changed.

Ottieni i metodi di pagamento dei clienti

Prima di offrire un upsell, recupera i metodi di pagamento salvati del cliente:

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.retrievePaymentMethods(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.retrieve_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.CustomerGetPaymentMethodsResponseItem, error) {
    client := dodopayments.NewClient(
        option.WithBearerToken(os.Getenv("DODO_PAYMENTS_API_KEY")),
    )
    
    resp, err := client.Customers.GetPaymentMethods(
        context.TODO(),
        customerID,
    )
    if err != nil {
        return nil, err
    }
    
    return resp.Items, 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)
    }
}

I metodi di pagamento vengono salvati automaticamente quando i clienti completano il checkout. Non è necessario salvarli esplicitamente.

Upsell post-acquisto con un clic

Offri prodotti aggiuntivi immediatamente dopo un acquisto riuscito. Il cliente può accettare con un solo clic poiché il suo metodo di pagamento è già salvato.

Quando usi payment_method_id, devi impostare confirm: true e fornire un customer_id esistente. Il metodo di pagamento deve appartenere a quel cliente.

Modalità di proporzione

Scegli come vengono addebitati i clienti quando aggiornano:

Modalità	Comportamento	Ideale per
`difference_immediately`	Addebita immediatamente la differenza di prezzo ( $30→$ 80 = $50)	Upgrade semplici
`prorated_immediately`	Addebita in base al tempo residuo nel ciclo di fatturazione	Fatturazione equa basata sul tempo
`full_immediately`	Addebita l’intero importo del nuovo piano, ignorando il tempo rimanente	Il ciclo di fatturazione si resetta

Usa difference_immediately per flussi di upgrade lineari. Usa prorated_immediately quando vuoi considerare il tempo inutilizzato sul piano corrente.

Cross-Sell

Aggiungi prodotti complementari per i clienti esistenti senza richiederne il reinserimento dei dettagli di pagamento.

Downgrade dell’abbonamento

Quando i clienti vogliono passare a un piano di livello inferiore, gestisci la transizione in modo fluido con crediti automatici.

Come funzionano i downgrade

Il cliente richiede il downgrade (Pro → Basic)
Il sistema calcola il valore rimanente del piano attuale
Il credito viene aggiunto all’abbonamento per i rinnovi futuri
Il cliente passa immediatamente al nuovo piano

TypeScript
Python
Go

async function downgradeSubscription(
  subscriptionId: string,
  newProductId: string
) {
  // Preview the downgrade first
  const preview = await client.subscriptions.previewChangePlan(subscriptionId, {
    product_id: newProductId,
    quantity: 1,
    proration_billing_mode: 'difference_immediately'
  });

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

  // Execute the downgrade
  const result = await client.subscriptions.changePlan(subscriptionId, {
    product_id: newProductId,
    quantity: 1,
    proration_billing_mode: 'difference_immediately'
  });

  // Credits are automatically applied to future renewals
  return result;
}

// Downgrade from Pro ($80) to Basic ($30)
// $50 credit added to subscription, auto-applied on next renewal
const downgrade = await downgradeSubscription('sub_123', 'prod_basic_plan');

def downgrade_subscription(subscription_id: str, new_product_id: str):
    # Preview the downgrade first
    preview = client.subscriptions.preview_change_plan(
        subscription_id=subscription_id,
        product_id=new_product_id,
        quantity=1,
        proration_billing_mode="difference_immediately"
    )
    
    print(f"Credit to be applied: {preview.credit_amount}")
    
    # Execute the downgrade
    result = client.subscriptions.change_plan(
        subscription_id=subscription_id,
        product_id=new_product_id,
        quantity=1,
        proration_billing_mode="difference_immediately"
    )
    
    # Credits are automatically applied to future renewals
    return result

# Downgrade from Pro ($80) to Basic ($30)
# $50 credit added to subscription, auto-applied on next renewal
downgrade = downgrade_subscription("sub_123", "prod_basic_plan")

func downgradeSubscription(subscriptionID string, newProductID string) error {
    client := dodopayments.NewClient(
        option.WithBearerToken(os.Getenv("DODO_PAYMENTS_API_KEY")),
    )
    
    // Preview the downgrade first
    preview, err := client.Subscriptions.PreviewChangePlan(
        context.TODO(),
        subscriptionID,
        dodopayments.SubscriptionPreviewChangePlanParams{
            UpdateSubscriptionPlanReq: dodopayments.UpdateSubscriptionPlanReqParam{
                ProductID:            dodopayments.F(newProductID),
                Quantity:             dodopayments.F(int64(1)),
                ProrationBillingMode: dodopayments.F(dodopayments.UpdateSubscriptionPlanReqProrationBillingModeDifferenceImmediately),
            },
        },
    )
    if err != nil {
        return err
    }
    
    fmt.Printf("Customer credits to be applied: %v\n", preview.ImmediateCharge.Summary.CustomerCredits)
    
    // Execute the downgrade (returns no response body; nil error means success)
    return client.Subscriptions.ChangePlan(
        context.TODO(),
        subscriptionID,
        dodopayments.SubscriptionChangePlanParams{
            UpdateSubscriptionPlanReq: dodopayments.UpdateSubscriptionPlanReqParam{
                ProductID:            dodopayments.F(newProductID),
                Quantity:             dodopayments.F(int64(1)),
                ProrationBillingMode: dodopayments.F(dodopayments.UpdateSubscriptionPlanReqProrationBillingModeDifferenceImmediately),
            },
        },
    )
}

I crediti derivanti da downgrade tramite difference_immediately sono limitati all’abbonamento e vengono applicati automaticamente ai rinnovi futuri. Sono distinti dalle assegnazioni di Credit-Based Billing.

Esempio completo: Flusso di upsell post-acquisto

Ecco un’implementazione completa che mostra come offrire un upsell dopo un acquisto riuscito:

Migliori Pratiche

Time Your Upsells Strategically

Il momento migliore per offrire un upsell è subito dopo un acquisto riuscito, quando i clienti sono ancora in modalità di acquisto. Altri momenti efficaci:

Dopo il raggiungimento di traguardi di utilizzo delle funzionalità
Quando si avvicinano ai limiti del piano
Al completamento dell’onboarding

Validate Payment Method Eligibility

Prima di tentare un addebito con un clic, verifica il metodo di pagamento:

È compatibile con la valuta del prodotto
Non è scaduto
Appartiene al cliente

L’API convaliderà questi elementi, ma verificarli proattivamente migliora l’UX.

Handle Failures Gracefully

Quando gli addebiti con un clic falliscono:

Torna al flusso di checkout standard
Notifica il cliente con messaggi chiari
Offri la possibilità di aggiornare il metodo di pagamento
Non ripetere continuamente addebiti falliti

Provide Clear Value Proposition

Gli upsell convertono meglio quando i clienti capiscono il valore:

Mostra cosa stanno ottenendo rispetto al piano attuale
Evidenzia la differenza di prezzo, non il prezzo totale
Usa la prova sociale (es. «Upgrade più popolare»)

Respect Customer Choice

Fornisci sempre un modo semplice per rifiutare
Non mostrare lo stesso upsell ripetutamente dopo un rifiuto
Monitora e analizza quali upsell convertono per ottimizzare le offerte

Webhook da monitorare

Monitora questi eventi webhook per flussi di upsell e downgrade:

Evento	Trigger	Azione
`payment.succeeded`	Pagamento upsell/cross-sell completato	Consegna il prodotto, aggiorna l’accesso
`payment.failed`	Addebito con un clic fallito	Mostra l’errore, offri tentativo o fallback
`subscription.plan_changed`	Upgrade/downgrade completato	Aggiorna funzionalità, invia conferma
`subscription.active`	Abbonamento riattivato dopo cambio piano	Concedi accesso al nuovo livello
