Mollie Payment Gateway for Business Central is a build-to-order AL extension that brings native European payment methods directly into Microsoft Dynamics 365 Business Central. It is designed for Benelux and wider EU SMBs who want their customers to pay with the methods they actually use — iDEAL, Bancontact, SEPA Direct Debit, credit cards and Apple Pay — without exporting invoices to a separate portal or stitching together brittle middleware.

ECOSIRE builds, installs and supports this as a per-tenant extension (not an AppSource one-click app) on your Business Central Online or on-premises environment. We provision it against your tenant, wire it to your Mollie organisation and live Profile via the Mollie REST API, and configure permission sets, a job queue entry for status polling and webhook handling, and your payment-method-to-G/L mapping.

Functionally, the extension adds a Mollie Setup page, table and page extensions on the Sales Invoice and Posted Sales Invoice, and event subscribers on posting and payment-registration codeunits. Sales staff generate a hosted pay-by-link straight from a posted invoice; the customer pays via their preferred method; Mollie webhooks (received through a BC API endpoint) update payment status. On settlement, the extension reconciles Mollie settlements against open invoices and proposes bank reconciliation lines, syncing refunds and chargebacks back to the document.

Because every BC deployment differs — localisations, custom number series, multi-company, posting-group conventions — we tailor the mapping, currencies and document flow to your setup rather than forcing a generic template. You get clean AL source, a documented permission set and a named ECOSIRE engineer for the build and post-go-live support window.
