Quick answer
What payment integrations does Seypro build? Seypro engineers payment integrations for systems where money has to reconcile — card checkout, recurring billing, affiliate payouts, and bank-grade settlement pipelines. We've shipped MPGS card checkout via Nouvobanq for a multi-language booking platform, and built the ABSA settlement layer behind MERJ Exchange, a regulated securities exchange. Every integration is reconciled, idempotent, and audit-logged.

Capabilities
Built for the parts that fail in production.
Webhooks that retry. Transactions that can't double-charge. Ledgers that balance. The unglamorous engineering that keeps money correct.
Idempotent webhooks
Gateway callbacks handled with idempotency keys and retry-safe processing — no double-charges, no lost notifications.
Ledger & reconciliation
Double-entry ledgering and automated reconciliation against gateway and bank statements so the books always balance.
PCI-aware design
Tokenisation and hosted fields keep card data out of your servers — PCI DSS scope minimised by architecture, not paperwork.
Audit trails
Every transaction, refund, and payout is versioned and traceable — the evidence regulators and finance teams actually ask for.
Bank file pipelines
ISO 20022 pain.001 / RTGS payment files generated, signed, and delivered over secure SFTP with status polling.
Gateway-agnostic
We integrate the gateway and bank you already use — Mastercard MPGS, regional acquirers, and card-scheme rails.
