The Payroll Interface / Integration Hub is a custom-engineered integration layer that connects Dynamics 365 Finance & Operations to the external payroll engine or bureau you already use — without forcing you onto a single vendor's payroll module.

ECOSIRE builds this as a per-tenant extension in AL, deployed directly to your Business Central / Dynamics 365 environment. It exposes a staging area and mapping engine: employee master, position, and pay-cycle data flow out to your payroll provider, and the calculated earnings, deductions, employer contributions and net-pay results flow back in. We model the bi-directional exchange over the Business Central REST/OData v4 API (or a SFTP/CSV bridge where your bureau requires file-based exchange), driven by the job queue so each pay run is scheduled, logged and retryable.

The heart of the build is configurable mapping. Your provider's earning and deduction codes are mapped to your chart of accounts through GL posting templates you control on a setup page — no hard-coded account numbers buried in code. An event-subscriber layer validates every inbound record before posting: unmatched codes, missing dimensions, and out-of-balance batches are flagged in a reconciliation worklist rather than silently posting bad journals.

Because it is build-to-order, the connector is shaped to your actual provider, your dimensions, and your approval flow — then handed over with permission sets, documentation and a support agreement.

This is not an instant AppSource download. ECOSIRE scopes, builds, tests against your sandbox, and installs the extension on your tenant, then supports it. Typical delivery is a few weeks depending on the number of providers and the complexity of your earnings/deduction catalog.
