Selling on Bukalapak while running Dynamics 365 Business Central usually means two disconnected worlds. Orders are re-keyed from the seller dashboard into sales orders, stock is adjusted by hand across warehouse and marketplace, tracking numbers are pasted back one at a time, and the settlement report at the end of the payout cycle never matches the bank statement because commission, service fees, shipping subsidies and promotional discounts were never posted anywhere. Business Central out of the box has no marketplace concept at all — no channel-order table, no listing entity, no fee mapping — so the gap gets filled with spreadsheets, a part-time data-entry role, and inventory that is wrong often enough to cause oversells.

What we build is an AL extension for your Business Central tenant that treats Bukalapak as a first-class sales channel. New tables hold the raw marketplace payload (channel order, channel order line, listing, settlement transaction) so nothing is lost in translation, and table extensions add channel provenance to Sales Header, Sales Line, Item and Item Ledger Entry — you can always trace a posted invoice back to the marketplace order it came from. A set of codeunits handles the integration edges: an HTTP client for the Bukalapak seller API with token storage in isolated storage, refresh, retry with exponential backoff and full request/response logging; a mapping engine that translates marketplace order states into your document flow (new to sales order, packed to warehouse shipment, delivered to posted sales invoice, cancelled or returned to credit memo or a flagged exception); and a synchronisation engine driven by Job Queue Entry records so cadence is configurable per direction rather than hard-coded.

Stock and price flow the other way. Availability is calculated from the fields you actually trust — inventory on hand less reserved quantity, optionally per location or per a nominated marketplace buffer — and pushed to Bukalapak on a schedule or reactively via event subscribers on item ledger and sales posting. Listing export maps Business Central items and variants to Bukalapak categories and attributes through a maintainable mapping table, so a new SKU is published without leaving the ERP. Shipments push back automatically: once a warehouse shipment or sales shipment is posted, the carrier and tracking number are confirmed to the marketplace within the seller SLA window. Settlements are the part most connectors skip — we import each payout statement, break it into commission, service fee, shipping subsidy, promotion and adjustment lines, and generate the corresponding general journal or purchase invoice entries against the accounts your controller nominates, so the payout reconciles to the bank line rather than being plugged.

The extension ships with its own permission sets, telemetry to Application Insights where you use it, a role-centre-linked activity page showing queue depth and last-sync status, and setup pages for credentials, mapping and posting accounts. It is built as a per-tenant extension for Business Central online (or as an on-premises extension if that is where you run), targets the release wave you are actually on, and is written to survive upgrades: no base-application modifications, no data-per-company assumptions we have not agreed, and interfaces where you are likely to want your own logic. Where you already invest in Power Platform, the marketplace tables are exposed through API pages (REST API v2.0 / OData v4) so Power BI, Power Automate and Dataverse can read them without a second integration.

This is build-to-order, not an AppSource download. We start with a short scoping call, confirm your Bukalapak account structure, Business Central version and localisation, item and variant model, warehouse setup and finance posting rules, then write a fixed scope. Typical delivery is one working week from confirmed scope. You get the AL source, installation on your sandbox first, a UAT pass with your own orders and a rollback plan, then production deployment, training and a post-go-live support window. Nothing is sold as instantly downloadable, and nothing is claimed to work against a marketplace API contract we have not verified against your live seller account.
