Upsells & Downsells

Upsells e downsells permitem oferecer produtos adicionais ou mudanças de plano para os clientes usando seus métodos de pagamento salvos. Isso possibilita compras de um clique que ignoram a coleta de pagamento, melhorando drasticamente as taxas de conversão.

Post-Purchase Upsells

Ofereça produtos complementares imediatamente após o checkout com compras de um clique.

Subscription Upgrades

Mova clientes para níveis superiores com prorrateamento automático e faturamento instantâneo.

Cross-Sells

Adicione produtos relacionados a clientes existentes sem pedir novamente os dados de pagamento.

Visão geral

Upsells e downsells são estratégias poderosas de otimização de receita:

Upsells: Ofereça um produto de maior valor ou upgrade (ex.: plano Pro em vez de Basic)
Downsells: Ofereça uma alternativa de menor preço quando o cliente recusar ou fizer downgrade
Cross-sells: Sugira produtos complementares (ex.: add-ons, itens relacionados)

A Dodo Payments habilita esses fluxos por meio do parâmetro payment_method_id, que permite cobrar o método de pagamento salvo do cliente sem exigir que ele digite novamente os dados do cartão.

Benefícios principais

Benefício	Impacto
Compras de um clique	Pule completamente o formulário de pagamento para clientes recorrentes
Maior conversão	Reduza o atrito no momento da decisão
Processamento instantâneo	As cobranças são processadas imediatamente com `confirm: true`
Experiência contínua	Os clientes permanecem no seu app durante todo o fluxo

Como funciona

Pré-requisitos

Antes de implementar upsells e downsells, garanta que você tenha:

Customer with Saved Payment Method

Os clientes devem ter concluído pelo menos uma compra. Os métodos de pagamento são salvos automaticamente quando os clientes finalizam o checkout.

Products Configured

Crie seus produtos de upsell no painel da Dodo Payments. Eles podem ser pagamentos únicos, assinaturas ou complementos.

Webhook Endpoint

Configure webhooks para lidar com os eventos payment.succeeded, payment.failed e subscription.plan_changed.

Obtendo métodos de pagamento do cliente

Antes de oferecer um upsell, recupere os métodos de pagamento salvos do 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.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)
    }
}

Os métodos de pagamento são salvos automaticamente quando os clientes finalizam o checkout. Você não precisa salvá-los explicitamente.

Upsells pós-compra de um clique

Ofereça produtos adicionais imediatamente após uma compra bem-sucedida. O cliente pode aceitar com um único clique, pois seu método de pagamento já está salvo.

Ao usar payment_method_id, você deve definir confirm: true e fornecer um customer_id existente. O método de pagamento deve pertencer a esse cliente.

Upgrades de assinatura

Mova os clientes para planos de assinatura de nível superior com tratamento automático de prorrateamento.

Visualizar antes de confirmar

Sempre visualize as alterações de plano para mostrar aos clientes exatamente o que será cobrado:

TypeScript
Python
Go

async function previewUpgrade(
  subscriptionId: string,
  newProductId: string
) {
  const preview = await client.subscriptions.previewChangePlan(subscriptionId, {
    product_id: newProductId,
    quantity: 1,
    proration_billing_mode: 'difference_immediately'
  });

  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):
    preview = client.subscriptions.preview_change_plan(
        subscription_id=subscription_id,
        product_id=new_product_id,
        quantity=1,

        "new_plan": preview.new_plan,
        "effective_date": preview.effective_date
    }

# Show customer the charge before confirming
preview = preview_upgrade("sub_123", "prod_pro_plan")
print(f"Upgrade will charge: {preview['immediate_charge']}")

func previewUpgrade(subscriptionID string, newProductID string) (map[string]interface{}, error) {
    client := dodopayments.NewClient(
        option.WithBearerToken(os.Getenv("DODO_PAYMENTS_API_KEY")),
    )
    
    preview, err := client.Subscriptions.PreviewChangePlan(
        context.TODO(),
        subscriptionID,
        dodopayments.SubscriptionPreviewChangePlanParams{
            ProductID:             dodopayments.F(newProductID),
            Quantity:              dodopayments.F(int64(1)),
            ProrationBillingMode:  dodopayments.F(dodopayments.ProrationBillingModeDifferenceImmediately),
        },

        },
    )
    
    return result, err
}

// Upgrade from Basic ($30) to Pro ($80)
// With DifferenceImmediately: charges $50 instantly
upgrade, err := upgradeSubscription(
    "sub_123",
    "prod_pro_plan",
    dodopayments.ProrationBillingModeDifferenceImmediately,
)
if err != nil {
    panic(err)
}
fmt.Printf("Upgrade status: %s\n", upgrade.Status)

Modos de prorrateamento

Escolha como os clientes são cobrados ao fazer upgrade:

Modo	Comportamento	Ideal para
`difference_immediately`	Cobra a diferença de preço instantaneamente ( $30→$ 80 = $50)	Upgrades simples
`prorated_immediately`	Cobra com base no tempo restante no ciclo de faturamento	Cobrança justa baseada no tempo
`full_immediately`	Cobra o preço total do novo plano, ignorando o tempo restante	Ciclo de faturamento reinicia

Use difference_immediately para fluxos de upgrade diretos. Use prorated_immediately quando quiser contabilizar o tempo não utilizado no plano atual.

Cross-sells

Adicione produtos complementares para clientes existentes sem exigir que eles reentrem os dados de pagamento.

Downgrades de assinatura

Quando os clientes quiserem migrar para um plano inferior, trate a transição com elegância usando créditos automáticos.

Como funcionam os downgrades

Cliente solicita downgrade (Pro → Basic)
Sistema calcula o valor restante no plano atual
Crédito é adicionado à assinatura para futuras renovações
Cliente muda para o novo plano imediatamente

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');

Os créditos de downgrades usando difference_immediately são vinculados à assinatura e aplicados automaticamente às renovações futuras. Eles são diferentes dos Customer Credits.

Melhores práticas

Time Your Upsells Strategically

O melhor momento para oferecer um upsell é imediatamente após uma compra bem-sucedida, quando os clientes estão em uma mentalidade de compra. Outros momentos eficazes:

Após marcos de uso de recursos
Ao se aproximar dos limites do plano
Durante a conclusão do onboarding

Validate Payment Method Eligibility

Antes de tentar uma cobrança de um clique, verifique o método de pagamento:

É compatível com a moeda do produto
Não expirou
Pertence ao cliente

A API validará isso, mas verificar proativamente melhora a experiência.

Handle Failures Gracefully

Quando cobranças de um clique falharem:

Retorne ao fluxo de checkout padrão
Notifique o cliente com mensagens claras
Ofereça atualizar o método de pagamento
Não tente cobranças falhas repetidamente

Provide Clear Value Proposition

Upsells convertem melhor quando os clientes entendem o valor:

Mostre o que estão recebendo em comparação ao plano atual
Destaque a diferença de preço, não o preço total
Use prova social (ex.: “Upgrade mais popular”)

Respect Customer Choice

Sempre ofereça uma forma fácil de recusar
Não mostre o mesmo upsell repetidamente após uma recusa
Acompanhe e analise quais upsells convertem para otimizar as ofertas

Webhooks para monitorar

Acompanhe estes eventos de webhook para fluxos de upsell e downgrade:

Evento	Gatilho	Ação
`payment.succeeded`	Pagamento de upsell/cross-sell concluído	Entregue o produto, atualize o acesso
`payment.failed`	Cobrança de um clique falhou	Mostre o erro, ofereça nova tentativa ou fallback
`subscription.plan_changed`	Upgrade/downgrade concluído	Atualize os recursos, envie confirmação
`subscription.active`	Assinatura reativada após mudança de plano	Conceda acesso ao novo nível
