3. Advantages and disadvantages

PayPal – Advantages

• Very high level of trust among consumers

• Quick and simple to activate and integrate

• Buyer protection is a strong selling point in favour of PayPal

• Extremely widespread in German e-commerce

PayPal – Disadvantages

• Relatively high fees compared to some other methods

• In case of disputes or risk flags, account freezes or payout delays can occur

• Conflict resolution can be time-consuming for merchants

---

Stripe – Advantages

• Excellent API and developer experience, highly customisable checkout

• White-label approach: you can fully brand the payment form in your own design

• Supports credit / debit cards, Apple Pay, Google Pay, and many local methods

• Solid technical support and very good documentation

Stripe – Disadvantages

• Requires technical implementation (developer resources or an agency)

• Does not natively provide invoice purchase (Rechnung) or a classic Sofortüberweisung product like Klarna

• For very small shops with no technical capacity, setup can feel demanding

---

Klarna – Advantages

• Offers invoice purchase (Rechnung), instalment plans, and Sofortüberweisung

• Can significantly increase conversion rates and average order value,
  as customers can buy now and pay later

• Depending on the contract, Klarna often assumes the default risk

Klarna – Disadvantages

• Higher fees compared to simple card payments and wallets

• Payout to the merchant can be delayed, depending on Klarna’s model and settlement terms

• Integration and contract conditions can be more complex

• Customer experience is tied to Klarna’s own risk and communication processes

4. Ideal use case for each provider

Store scenario – Best fit

• You want to offer common payment methods quickly and without much effort
  → PayPal

• You have an in-house tech team and want a fully customised checkout
  → Stripe

• You want to offer invoice payments and instalment plans
  → Klarna – ideally in combination with Stripe or a multi-provider gateway like Mollie

---

Many successful online shops offer 2–3 providers in parallel
to maximise customer choice and conversion.

Example setup:

• Stripe for card payments + Apple Pay / Google Pay

• PayPal as a highly trusted wallet option

• Klarna for invoice, instalments, and Sofortüberweisung

---

5. Other providers worth considering

Mollie

• Very user-friendly interface

• Allows you to integrate Klarna, SEPA direct debit, PayPal, cards, and more
  via one unified platform

• Great if you want a flexible multi-method payment solution without building everything yourself

Unzer (formerly Heidelpay)

• Strong focus on larger German merchants and B2B scenarios

• Offers various invoice and B2B payment models

• Good option if you have complex enterprise requirements

Amazon Pay

• Leverages customers’ existing Amazon accounts and stored payment methods

• Good trust factor, as many users are familiar with Amazon

• But its relevance has plateaued or declined somewhat in recent years in some sectors

giropay / paydirekt

• Primarily interesting if you want to explicitly support
  German bank-based online payments directly from current accounts

• Rather a niche / complementary method, rarely used as a standalone solution
