Seypro builds payment integrations \u2014 hosted and embedded card checkout, recurring billing, affiliate commission and payout systems, and bank-grade settlement. We've shipped MPGS card checkout via MCB Seychelles for a multi-language booking platform, and built the ABSA settlement layer behind MERJ Exchange. Every integration is reconciled, idempotent, and audit-logged.
Payment integration engineering — accepting cards, charging on a schedule, and paying money back out, wired into the software you already run. We integrate hosted and embedded checkout, 3-D Secure and tokenisation, webhooks with idempotent retry handling, and the reconciliation that proves every cent landed where it should. Not a checkout plugin dropped onto a template — payment infrastructure engineered for correctness under real load.
Coverage spans collection (hosted gateway checkout, embedded card forms, multi-currency, 3-D Secure, tokenised card-on-file), billing (subscriptions, metered and usage-based pricing engines, dunning, invoicing), and payouts (affiliate commission tracking, marketplace splits, automated disbursements, and bank-grade payment-file pipelines such as RTGS and ISO 20022 pain.001 delivered over SFTP). Every flow is idempotent, audit-logged, and reconciled against a ledger.
Shipped in production: MPGS via MCB Seychelles hosted checkout for a multi-language booking platform, an affiliate commission and payout system for a SaaS product, and the ABSA settlement layer behind MERJ Exchange — a regulated securities exchange clearing under bank-grade rails. For the full hub — Cybersource, Stripe, Paystack, Flutterwave, PayPal, plus regional pages — see /payments. For Seychelles-specific work, see payments in Seychelles. We work with your existing gateway and bank, not against them — and we hand over code you own.
What we wire up
The full money path \u2014 accepting it, charging on a schedule, and moving it back out. One integration, reconciled end to end.
Hosted or embedded card checkout, multi-currency, 3-D Secure, and tokenised card-on-file — wired into your existing gateway with webhooks that retry and reconcile.
Subscriptions, usage-based pricing engines, affiliate commissions, and automated payouts — ledgered, reconciled, and ready for finance to trust.
Capabilities
Webhooks that retry. Transactions that can't double-charge. Ledgers that balance. The unglamorous engineering that keeps money correct.
Gateway callbacks handled with idempotency keys and retry-safe processing — no double-charges, no lost notifications.
Double-entry ledgering and automated reconciliation against gateway and bank statements so the books always balance.
Tokenisation and hosted fields keep card data out of your servers — PCI DSS scope minimised by architecture, not paperwork.
Every transaction, refund, and payout is versioned and traceable — the evidence regulators and finance teams actually ask for.
ISO 20022 pain.001 / RTGS payment files generated, signed, and delivered over secure SFTP with status polling.
We integrate the gateway and bank you already use — Mastercard MPGS, regional acquirers, and card-scheme rails.
