Connect BigCommerce with Mollie to offer iDEAL, cards, PayPal, and local EU methods, reduce checkout friction, and track cleaner payment performance in your store data.
• Bigcommerce sends order totals, currency, customer, and return URLs to Mollie to create a payment, then stores the Mollie payment ID on the order for traceability.
• Mollie webhooks notify status transitions (authorized, paid, failed, canceled, expired, chargeback), and those states are mapped to Bigcommerce order and payment statuses.
• Refund events created in Mollie (full or partial) are linked to the original payment ID and written back to the corresponding Bigcommerce order history.
• Payment method metadata (iDEAL, Bancontact, cards, PayPal, Klarna where enabled) is stored on the order so reporting can be filtered by Mollie method.
• Idempotent webhook handling de-duplicates repeated callbacks, and signature/secret validation is applied before any order update is accepted.
• Errors, mismatched totals, and unknown payment IDs are logged with correlation IDs to support auditing and faster incident triage.

We install and configure Mollie in BigCommerce, then validate payment flows end to end, including capture, refunds, and cancellations. You get consistent order status updates so ops and support work from one source of truth.
We map Mollie states like paid, authorized, canceled, refunded, and chargeback to the right BigCommerce order statuses. This reduces mis-fulfillment and makes customer service actions predictable.
Yes, when the BigCommerce order and Mollie transaction are aligned at line-item level and tested with real scenarios. We also add safeguards so finance can reconcile refunds without manual fixes.
BigCommerce does not store every settlement detail by default, so we typically push Mollie transaction metadata into custom fields or your BI stack. That makes payout matching and dispute tracking easier to audit.
Mollie supports multiple EU payment methods and currencies, and BigCommerce can run multiple storefronts and price lists. We confirm currency, tax, and refund behavior per store view before go-live.
