Managing Recurring Payments & Subscriptions: Cards vs Bank Debits

What is Managing Recurring Payments & Subscriptions: Cards vs Bank Debits?

Learn how to structure recurring payments for your SaaS or e-commerce. A deep dive linking SEPA Direct Debit (SDD) vs Credit Cards to reduce your churn rate.

If you currently force customers to manually pay an invoice every month, you don't really have a subscription business. You have a massive collection nightmare.

Even if you automate it by saving the customer's credit card, you will hit a wall:
Cards expire after 3 years.
Cards get lost and replaced.
Banks block automatic payments due to strict PSD2 fraud rules.

When a card payment fails, the customer often won't bother updating it. This is called Involuntary Churn, and it silently massacres your recurring revenue.

Method 1: Recurring Card Payments (MIT)

If you want to pull money automatically from a credit card without the user being present, you must use a framework called Merchant Initiated Transactions (MIT).

How you set it up:
During the very first checkout, the customer must strongly authenticate the payment (using 3D Secure / a banking app). At that exact moment, your payment gateway generates a special encrypted "Subscription Token".

Next month, your server uses this specific token to ask the bank for 20€. Because the bank sees it's flagged as an MIT agreement, it legally lets the payment pass without asking the customer for an SMS confirmation.

Method 2: SEPA Direct Debit (The Heavy Lifter)

If you operate in Europe, Cards are completely outclassed by SEPA Direct Debit (SDD) for subscription models.

SDD securely connects directly to the customer's IBAN (bank account). You get them to sign a digital mandate (SDD Core) once.

Why SEPA wins for subscriptions:
1. Zero Expiration: Bank accounts don't expire every 3 years. Unless they physically change banks, your billing will succeed forever.
2. Drastically cheaper: Processing a €20 SEPA charge costs a fraction of a card transaction.
3. Perfect for B2B: Businesses hate paying massive monthly software fees on credit cards. They much prefer a direct IBAN debit.

How to Build a Seamless Subscription Flow

Don't build this from scratch. A high-end API like RoxPay gives you a dedicated "Subscriptions Engine".

You simply pass the engine an instruction: "Charge Jane Doe €15 on the 1st of every month."

The engine handles everything: securely storing the card/SEPA vault tokens, executing the charge on schedule, firing a webhook to your server if the card bounces, and automatically sending Jane an email with a secure link to update her expired card.

Frequently Asked Questions

Can I use Account-to-Account (Open Banking) for recurring payments?

Yes, but with caveats. Standard A2A payments require active FaceID/Fingerprint authentication for every single transaction. To do it automatically in the background, you must use "Variable Recurring Payments (VRP)", a brand-new Open Banking standard that is slowly rolling out across European banks.

What happens if a SEPA Direct Debit bounces due to insufficient funds?

Unlike a card transaction which fails instantly, SEPA is delayed. The bank might notify you of a "Return/R-Transaction" 2 to 5 days later. Your system must be built asynchronously via webhooks to suspend the user's account once the rejection event is received.
