In B2B e-commerce, payment behavior differs fundamentally from the consumer world. Business buyers do not pay with their personal credit card — they pay from the company account, by invoice, on schedule, with cash discount and within agreed payment terms. Any B2B online shop that does not offer invoice purchase loses revenue. Any shop that offers it without protection risks payment defaults. We develop a payment method concept that solves both: maximum purchasing intent combined with controlled default risk.
The B2B payment stack: six secured layers
The Most Important B2B Payment Methods at a Glance
Not every payment method suits every customer and every order size. In our projects we always configure payment methods depending on customer segment, credit limit and order value. The following grid shows the six payment methods we regularly implement in B2B checkouts — and explains when each one makes sense.
Invoice Purchase
By far the most requested payment method in B2B. The buyer receives goods and invoice, then pays within the agreed term (14, 30 or 45 days). In the Shopware checkout we control availability via credit limits, creditworthiness and customer group. Cash discount tiers, dunning interfaces and DATEV export are included.
SEPA Direct Debit
Automatic debit from the buyer's business account after the payment period expires. Ideal for regular customers with framework agreements. We implement SEPA mandate management, validate BIC/IBAN at checkout and provide SEPA XML files for your bank. The pre-notification is sent automatically by email.
Credit Limit and Installment
For large customers with high order volumes: an assigned credit limit caps the outstanding order value and is automatically released after payment is received. Via the ERP interface we synchronize limit balance and payment receipts in real time between shop and accounting system.
Credit Check at Checkout
Automated verification of company addresses and payment history directly at order completion. New customers and orders above defined thresholds are reviewed before invoice purchase is released. The check logic is configurable: manual, via internal scoring rules or via connected external credit bureaus.
Bank Transfer with Reference
Classic bank transfer with an automatically generated payment reference per order. The system matches incoming transfers automatically against open invoices, sends payment confirmations to the buyer and reports overdue items to the sales team. Particularly suited for international B2B customers who prefer SWIFT transfers.
Payment Approvals and Workflows
Certain payment methods (e.g. invoice purchase above the limit) require internal approval. We link the payment checkout to the B2B portal approval workflow: orders that exceed the credit limit automatically enter a holding queue and are presented to the responsible employee for approval.
| Payment method | When it fits | Safeguard | Availability |
|---|---|---|---|
| Invoice purchase | Regular customers, standard orders | Credit limit and credit check | Per customer group and limit |
| SEPA B2B direct debit | Framework agreements, recurring | Irrevocable B2B mandate | Only with active mandate |
| Prepayment / bank transfer | New and international customers | Payment before dispatch | Always available |
| Credit card / online | Small and international orders | Instant authorization | Optional add-on |
Which combination is right for you depends on your customer structure. A wholesaler with fixed framework agreements runs most efficiently on invoice purchase and SEPA B2B direct debit, while a manufacturer with many international new customers starts with prepayment and bank transfer and activates invoice purchase step by step. We map this logic rule-based, so every customer group sees exactly the payment methods that match its risk profile — adjustable in the backend at any time.
Invoice Purchase Implemented Technically
Invoice purchase sounds simple, but in a B2B checkout it is technically demanding. The key is not merely displaying a payment option — it is deciding dynamically for which customer, at which order value and under which conditions invoice purchase may be offered. The following mechanisms are part of every B2B project we implement with invoice purchase.
Credit Limit Control and Payment Approval
Dynamic Credit Limit Control at Checkout
Invoice purchase sounds simple, but in a B2B checkout it is demanding: the task is to decide dynamically for which customer, at which order value and under which conditions invoice purchase may be offered. We retrieve the available credit limit from the ERP in real time; if the order value exceeds it, the method is hidden or the order is routed into an approval workflow.
- Dynamic limit check: overdue invoices automatically reduce the available limit
- Score-based activation: new customers receive an initial limit via internal review or credit bureau
- Payment terms and cash discount: 14, 30 or 45 days net per customer group, synced from the ERP and posted correctly via the DATEV interface
Credit limit from the ERP — no duplicate maintenance
Secure invoice purchase without slowing the checkout
We combine credit limit checks, credit scoring and ERP sync into a checkout that stays fast and keeps default risk under control. Implementation from 4,900 € net.
SEPA Direct Debit in the B2B Checkout
SEPA Core direct debit and SEPA B2B direct debit differ substantially in their legal characteristics. For business customers the SEPA B2B direct debit is recommended: it cannot be reversed, offers the creditor greater security and is more binding for the debtor. We implement both variants and integrate mandate management seamlessly into the B2B customer portal.
- SEPA mandate authorization directly in checkout or in the customer self-service portal
- Automatic IBAN/BIC validation and plausibility check of bank details
- Pre-notification by email at least 1 day before collection (configurable per customer group)
- XML export of direct debits in SEPA format for your bank (ISO 20022 pain.008)
- Automatic posting and reconciliation with open items after successful collection
- Returned direct debit management: block orders, adjust credit limit, send notification
Credit Checks: Security Without Abandoned Carts
A credit check is the most important safeguard for invoice purchase — but it must not slow down the checkout. In practice many implementations fail because checks take too long or are too restrictive and reject legitimate customers. We rely on a three-tier model that is fast, accurate and purchase-friendly.
Level 1: Internal Whitelist
Regular customers with a positive payment history are maintained on an internal whitelist. For these customers the external credit check is skipped entirely — invoice purchase up to the stored limit is immediately available. This significantly accelerates checkout and prevents unnecessary queries for established, reliable business partners.
Level 2: Rule-Based Scoring
For unknown customers or orders above a threshold, an internal scoring model evaluates available data: company address, order history in the shop, account age and shopping cart composition. Low-risk profiles receive invoice purchase up to a configured starting limit automatically.
Level 3: Manual Approval
Orders that exceed scoring thresholds or show an unusual profile are queued for manual review. The clerk sees all relevant information consolidated in the shop backend: order details, customer history and scoring result. Approval or rejection is done with one click and automatically triggers notification to the buyer.
Level 4: Continuous Recalibration
After each payment transaction and each dunning stage, the system updates the internal score automatically. Prompt payers improve their rating and receive higher limits; customers with late payments are downgraded. This learning mechanism reduces manual review effort over time as more customers migrate to the whitelist.
Controlling Payment Methods Per Customer Group
Not all of your business customers share the same needs and risk profile. In the Shopware backend we configure payment methods precisely by customer group, order value and country. A new customer from abroad may see only prepayment, while a long-standing framework agreement customer automatically receives invoice purchase up to 50,000 euros. This control is rule-based and can be maintained in the backend without developer involvement.
Customer Group Configuration
Each customer group (e.g. new customer, regular customer, framework agreement, international customer) receives its own payment method configuration. Available methods, limits and payment terms are set per group.
Order Value Thresholds
Payment methods can be shown above or below defined order values. Invoice purchase automatic up to 5,000 euros, above that only after approval. Prepayment always available as fallback.
Country and Currency Control
For international B2B customers we configure country-specific payment methods, currencies and tax displays. SEPA applies only within the euro zone; bank transfer and invoice purchase are also available for non-EU buyers.
Integration with ERP, Accounting and Dunning
Payment methods only work smoothly when downstream systems are properly connected. An invoice purchase checkout without an ERP link generates invoices that must be transferred manually to the accounting system — inefficient and error-prone. We integrate the payment checkout seamlessly with your existing system landscape.
ERP Order Transfer
Every completed order is automatically transferred to the ERP as a sales order with complete payment information. Payment method, due date, cash discount date and outstanding amount are immediately available for accounts receivable.
DATEV Export and GoBD
Invoices, credit notes and payment receipts are passed to DATEV in a GoBD-compliant manner via the integration interface. Account assignment rules for various payment methods, tax rates and cash discount postings are preconfigured and adjustable.
Dunning Integration
Overdue invoices are automatically registered in the ERP dunning module. Dunning levels, dunning fees and credit limit blocks after each dunning stage are configurable. Simultaneously, the customer's Shopware payment method is adjusted automatically.
Punchout and payment methods
Implementation Process: From Concept to Live Checkout
Requirements Analysis and Concept
Together we capture which payment methods are relevant for which customer segments, how credit limits are managed today and which ERP systems need to be connected. The result is a payment method concept describing limits, activation rules, integration requirements and the approval workflow.
Shopware Configuration and Extension
We configure Shopware Community Edition for your payment requirements: customer groups, payment methods, checkout rules and limit check logic. For requirements beyond the standard, we develop custom Shopware plugins — for example for ERP limit synchronization or automatic SEPA XML export.
ERP and Accounting Integration
We connect your ERP for credit limit queries, order handover and payment receipt processing. For the DATEV connection we define account assignment rules, test posting entries with your accountant and validate the GoBD-compliant archiving path.
Testing and Go-Live
All payment methods are tested systematically: normal checkout, boundary scenarios (limit exactly exhausted), error handling (invalid IBAN, limit exceeded), returned direct debits and dunning triggers. After sign-off by your accounting and IT teams, we go live in a phased rollout.
Security and Compliance in B2B Payments
Payment data is among the most sensitive information in a B2B system. Account details, credit limits and payment histories must be protected against unauthorized access and processed in compliance with data protection law. Our implementations follow current security standards: SEPA mandate data is stored encrypted, access rights to payment information are role-restricted, and GDPR-compliant data processing agreements with connected services are in place.
In the Shopware backend we control which roles may view, modify or export payment information. Accountants see invoice data, sales staff see credit limits, warehouse staff see no financial data. This separation prevents internal data incidents and satisfies typical requirements from internal audits and certification processes. In the B2B portal, customer administrators can define per user who may download invoices, change payment methods or manage the SEPA mandate. The articles B2B Payment Methods: Invoice Purchase and Credit Limit, E-Invoicing Mandate 2027: Prepare B2B Shop and ERP and B2B Checkout: Reducing Cart Abandonment show how the individual building blocks interlock.
In addition, every change to credit limits, payment methods or approvals is logged in an audit-proof manner with a timestamp and the responsible user. This lets you demonstrate at any internal review who made which decision and when — a requirement that quickly gains importance in invoice-purchase business as volumes grow.
