Tabby BNPL for Business Central is a per-tenant AL extension that wires Tabby's buy-now-pay-later (split-in-4 and pay-later) into your Dynamics 365 Business Central order-to-cash flow. ECOSIRE builds it to your environment, installs it as a tenant-specific extension (not a generic AppSource download), and supports it after go-live.

At order time, the extension calls Tabby's checkout/sessions API to run an eligibility and credit-limit check, then presents the BNPL option to the customer. On approval, the order is authorized and captured; refunds and partial refunds are issued back through Tabby directly from the Sales Order or Posted Sales Invoice using an AL action and event subscribers on the posting routines — no separate portal switching.

The real accounting value is in reconciliation. Tabby settles net of fees on a payout cycle, so we map each Tabby payout to the originating BC documents, post the merchant fee to a dedicated G/L account, and clear the AR balance so your customer ledger and bank reconciliation actually tie out. Multi-currency GCC is handled natively for AED, SAR and KWD using BC's currency and exchange-rate framework.

Technically this is delivered as table and page extensions over Sales and Payments, event subscribers (OnAfterPost, OnBeforeRelease), a job queue entry that polls settlement status, dedicated permission sets, and a secured API/webhook endpoint for Tabby callbacks. Credentials live in isolated setup tables, never in code.

Because it is built-to-order, you get a clean fit to your chart of accounts, your tax setup and your sandbox-then-production rollout — with an honest delivery lead time rather than a one-click promise. ECOSIRE delivers, deploys to your sandbox, validates against Tabby's test environment, then promotes to production.
