Newegg Marketplace Connector for Dynamics 365 Business Central

Key Features

Newegg Seller API integration from dedicated AL codeunits, with seller ID and secret key held in isolated storage and a connection test action on the `Newegg Setup` page

Order import into a staging table first, so unmapped SKUs, unknown ship-to countries or malformed payloads are quarantined and correctable rather than silently dropped

Configurable marketplace status mapping — unshipped, partially shipped, shipped, voided and refunded states mapped onto sales order, shipment and credit memo flows

SKU mapping table linking Newegg seller part number and Newegg item number to Business Central `Item No.` plus variant code, with bulk import from Excel

Stock synchronization driven by event subscribers on item ledger and reservation entries, publishing available-to-promise by location rather than raw on-hand quantity

Price synchronization with per-listing markup or price-list-driven values, including a dry-run mode that logs the intended change before the first live push

Listing export building Newegg category and attribute payloads from item card fields, item attributes and per-category templates maintained inside Business Central

Shipment confirmation push-back triggered by posting a warehouse shipment or sales invoice, sending carrier, service level and tracking number inside the Newegg SLA window

Settlement report ingestion split into revenue, commission, shipping credit, refund and adjustment components against configured G/L fee and clearing accounts

Generated general journal or cash receipt journal lines carrying the Newegg order number, so posted entries reconcile line-by-line to the bank deposit

Job queue entries for every sync direction with configurable intervals, per-company scheduling and an isolated retry policy per job

Full error and activity log retaining the raw request and response for a configurable period, plus a Newegg Sync Status factbox on the sales order card

Dedicated permission sets separating setup, operation and read-only roles, so warehouse users can confirm shipments without touching API credentials

API pages (REST API v2.0 / OData v4) exposing sync state, error log and mapping tables for Power BI, Power Automate or Dataverse consumption

About this Product

Selling on Newegg while running Dynamics 365 Business Central usually means two disconnected worlds. Orders are rekeyed from Seller Portal into sales orders, available quantities drift until an oversell forces a cancellation and a seller-performance hit, tracking numbers are pasted into Newegg by hand within the shipping SLA, and month-end reconciliation turns into a spreadsheet exercise where a settlement payout has to be matched back to hundreds of order lines, commission charges, shipping credits and refunds. Business Central is very good at the ERP half of that — items, locations, sales orders, warehouse shipments, posted invoices, bank reconciliation — but it ships with no Newegg awareness at all: no Newegg order source, no marketplace SKU mapping, no fee ledger, no place to record which payout settled which posted document.

We build that missing layer as a proper AL extension for your tenant. Newegg's Seller API is called from codeunits behind a Newegg Setup page holding the seller ID, secret key and marketplace/currency configuration, with credentials stored in isolated storage rather than in a table field. Incoming orders land first in a staging table so a malformed or partially-mapped order is quarantined and visible instead of failing silently; a mapping table translates Newegg seller part number and Newegg item number to Business Central Item No. and variant, and marketplace order status is mapped onto your document flow so an unshipped order becomes a sales order, a voided order becomes a cancellation, and a partially-shipped order does not re-import. Stock and price synchronization runs the other way: event subscribers on item ledger and reservation activity, plus a delta queue, publish available-to-promise quantities and price updates so the listed quantity reflects what your locations can actually ship, not the raw on-hand figure. Listing export builds Newegg's category and attribute payload from item card fields, item attributes and a per-category template you control.

On the outbound side, posting a warehouse shipment or sales invoice raises a shipment confirmation to Newegg with carrier, service level and tracking number, so the SLA clock is satisfied by the same act that posts the document — no second system to remember. Settlement is where most sellers get the largest return: we pull the settlement report, break it into order-level revenue, commission, shipping and refund components, and generate reconcilable general journal or cash receipt journal entries against your configured fee and clearing accounts, with each line carrying the Newegg order number so the posted entries reconcile to the bank deposit. Everything runs unattended through job queue entries you can schedule per company, with a retry policy and error log so a Newegg API outage produces a readable failure record rather than a gap in your data. The extension ships with its own permission sets, is built against current Business Central release waves, and targets SaaS online tenants (as a per-tenant extension or an AppSource-packaged app) or on-premises deployments; API pages (REST API v2.0 / OData v4) are exposed so Power Automate, Dataverse or your own reporting can read the sync state.

This is a build-to-order product, not an AppSource download. Nothing is pre-built and waiting: you request a quotation, we run a scoping call, and we write the specification around your actual catalogue, locations, fee accounts, tax setup and Business Central version. From confirmed scope, typical delivery is 2-4 weeks — longer if the scope includes multi-company, multi-warehouse allocation logic or a non-standard third-party fulfilment integration, and we say so before you commit rather than after. You receive the AL source code for the version we build, a staging deployment for UAT before anything touches production, and a support window after go-live.

What you get

Installable AL extension source code built and tested against your specific Business Central version and deployment model (SaaS online or on-premises)

Installation and configuration on your environment — setup page, SKU mappings, fee and clearing account setup, job queue entries and permission set assignment

Technical documentation: object ID range, table and page extension inventory, event subscriber map, API endpoints used and the settlement posting logic

End-user guide covering daily order processing, resolving quarantined orders, listing export and settlement reconciliation

Private Git repository handover with full commit history, so you or another partner can maintain the extension independently

Who this is for

E-commerce Operations Manager

Runs Newegg alongside other channels and is tired of rekeying orders and reconciling quantities across two systems. Needs orders in Business Central within minutes and listed stock to reflect what the warehouse can genuinely ship, so seller metrics stay clean and oversells stop.

Finance Manager or Controller

Owns month-end and currently reconciles Newegg payouts in a spreadsheet. Needs settlement components posted as reconcilable journal entries against defined fee accounts, with the Newegg order number on each line so a bank deposit ties back to posted documents without manual matching.

Warehouse and Fulfilment Lead

Ships against a marketplace SLA and cannot afford a second portal to update. Needs tracking numbers to reach Newegg automatically the moment a warehouse shipment or sales invoice is posted, and a visible failure log when a push does not land.

IT Manager or Business Central Partner

Responsible for the tenant's extension estate and upgrade path. Needs a properly structured AL extension with its own object range, permission sets, no modification of base objects, source code in hand, and documentation good enough to maintain after handover.

How Newegg Marketplace Connector for Dynamics 365 Business Central Compares

Criterion	ECOSIRE	Custom Build	Competitor	Dynamics 365 Business Central Native
Fit to your catalogue, accounts and process	Specified around your actual items, locations, fee accounts and tax setup at the scoping call	Full control, but you write the specification and carry the analysis effort yourself	Generic mapping designed for the average seller; edge cases handled by workarounds	No Newegg concept exists — sales orders are created manually
Settlement and fee reconciliation	Payout decomposed into revenue, commission, shipping and refunds, posted to your nominated G/L accounts	Achievable, but the settlement logic is the largest and most error-prone part to build	Often summary-level or export-to-CSV, leaving finance to match manually	Manual spreadsheet matching against bank deposits
Time to a working system	Typically 2-4 weeks from confirmed scope, with staging UAT included	Months, dependent on in-house AL capacity and competing priorities	Installs in a day, then weeks of configuration and gap workarounds	Immediate, because nothing is automated
Source code and lock-in	Full AL source plus Git repository handed over — maintainable by anyone	You own everything, and you own every future fix	Closed extension tied to a per-user or per-order subscription	Nothing to own
Upgrade path across release waves	Optional maintenance agreement covering each Business Central wave and Newegg API changes	Your team retests and repairs at every wave	Vendor-controlled timing; you wait for their release	Nothing to break, nothing to gain
Architecture and tenant hygiene	Dedicated object range, table and page extensions, event subscribers, own permission sets — no base-object modification	Quality depends entirely on the developer and the review discipline applied	Generally sound, but object range and behaviour sit outside your control	Standard Business Central objects only
Ongoing cost shape	One-off build cost plus an optional maintenance agreement	Internal developer time indefinitely, including opportunity cost	Recurring subscription that scales with users or order volume	No licence cost, paid instead in staff hours and oversell penalties
Error visibility when the Newegg API fails	Staging quarantine, retry policy and a readable error log with retained request and response	Built only if you specify it — commonly the first thing cut for time	Varies; often a status flag with limited diagnostic detail	Not applicable — failures surface as missing orders noticed later

Frequently Asked Questions about Newegg Marketplace Connector for Dynamics 365 Business Central

How long does delivery take?

This is built to order — typical delivery is 2-4 weeks from confirmed scope, not from the first enquiry. The scoping call and specification sign-off come first; the clock starts when you approve the scope. Wider scope (multi-company, multi-warehouse allocation rules, 3PL integration, or a non-standard tax setup) can extend that, and we put the realistic range in writing before you commit rather than discovering it mid-build.

Is this an instant download from Microsoft AppSource?

No. There is nothing pre-built to download. ECOSIRE builds the extension for your tenant against your Business Central version, catalogue and account setup. We can deliver it as a per-tenant extension for a SaaS environment, package it for on-premises deployment, or prepare it for an AppSource submission under your own publisher account if that forms part of the agreed scope.

What happens with support and updates after go-live?

Every build includes a post-go-live support window for defect fixes and first-settlement-cycle assistance. Business Central release waves land twice a year; we offer a maintenance agreement covering compatibility testing and adjustment for each wave, plus changes needed when Newegg alters its Seller API. Because you receive the source code and Git repository, you are never locked in — your own team or another partner can maintain it instead.

Which Business Central versions and deployment models are supported?

Current supported release waves, both SaaS online and on-premises. We confirm your exact version at the scoping call because it determines available AL language features, the API surface we can use, and whether the extension is installed as a per-tenant extension or deployed to an on-premises server. If you run an older unsupported version we will say so and discuss an upgrade path rather than building against something Microsoft no longer patches.

How does settlement reconciliation actually post?

The settlement report is decomposed into revenue, commission, shipping credits, refunds and adjustments. Each component posts to the general journal or cash receipt journal against G/L accounts you nominate during setup, with the Newegg order number written to the journal line so a payout can be traced to the specific posted sales documents. Nothing posts automatically without review unless you explicitly ask for that — the default is a reviewable journal batch.

Will this cause oversells if Newegg and Business Central disagree?

Synchronization publishes available-to-promise by location, factoring reservations rather than raw on-hand, and runs on a job queue at an interval you choose. No connector eliminates the physical latency between a marketplace purchase and your next sync, so we also configure a safety buffer per item or category. Every push is logged, so if a discrepancy occurs you can see exactly what quantity was sent and when.

Can we start with only order import and add the rest later?

Yes, and it is often the sensible sequence. A common phasing is order import plus stock sync first, then shipment confirmation, then settlement reconciliation once finance has agreed the account mapping. We scope it as phases with separate acceptance points; the object range and architecture are laid out at the start so later phases extend the same extension instead of becoming a second one.
