Cross-border card acceptance leaks money in two places at once: declines from acquirers that don't process a given currency or region well, and FX cost from converting at the wrong rate at the wrong time. Business Central's native Currencies, Currency Exchange Rates, and payment-registration pages handle the accounting side, but they have no concept of acquirer routing, multi-MID selection, or decline recovery. This extension fills that gap.

ECOSIRE builds this as a per-tenant AL extension installed directly onto your Business Central environment (cloud SaaS or on-prem). We add table and page extensions to your payment and customer documents, a Routing Rules setup table (currency, region, card scheme, amount band → preferred MID), and event subscribers on the posting and payment-application codeunits so routing decisions are captured and FX is booked correctly. Acquirer calls run through a configurable connector to your chosen gateway/PSP (for example Stripe, Adyen, or Checkout.com) over its REST API, with retries handled by the BC Job Queue.

When a payment is initiated, the extension scores eligible MIDs by currency/region fit and recent decline rate, presents (or auto-applies) dynamic currency conversion at checkout, locks the FX rate for the transaction, and on settlement posts the realized FX gain/loss to the G/L accounts you specify. Declined authorizations are re-routed to the next-best acquirer automatically. Everything is permission-set gated, telemetry-logged, and exposed via the BC REST/OData API and optionally surfaced in Power BI or Dataverse.

You receive a working, documented extension on your tenant — not a starter template. ECOSIRE handles design, AL development, installation, UAT, and ongoing support.
