eBay Integration

Zynk's eBay integration connects your eBay seller account to the accounting, ERP and shipping systems that run the rest of the business. Orders, inventory items and offers export from eBay, while stock levels, prices and shipping fulfilments go back to it. It suits marketplace sellers on Sage 50, Sage 200, Sage Accounting, Xero or Business Central.

Benefits

Why businesses connect eBay

eBay sales in the books

Orders export from eBay and arrive in your accounts or ERP as sales orders or invoices, coded to the customers, nominal accounts and tax rates you already use for every other channel.

Listings that reflect real stock

Stock levels and prices import into eBay from the system that owns them. Listings stop offering items that sold elsewhere, and a price change made in the back office reaches eBay on the next run.

Tracking on orders without Seller Hub

When an order ships, Zynk creates a shipping fulfilment against it in eBay with the carrier and tracking number, keeping buyers informed without anyone updating orders in Seller Hub by hand.

Inventory and offers on record

Inventory items and their offers export from eBay by SKU, giving you a clear view of what is listed, at what price and in what quantity, ready to compare against the item records in your ERP.

Carrier codes for each marketplace

Fulfilment policies export for each eBay marketplace, from Australia to Germany, so the shipping carrier codes used in your fulfilments match the ones eBay accepts on that site.

The problem

Why integrate eBay?

eBay brings in sales from buyers you might not otherwise reach, but every sale creates work behind the scenes. Orders need entering in the accounts, stock has to match what is left on the shelf and buyers expect tracking quickly. Handling that by hand across a large catalogue soon becomes a full-time job.

Without integration

  • eBay orders downloaded as a report and typed into Sage
  • Items that sold out in the shop still live on eBay
  • Price changes made in the ERP but never reaching listings
  • Tracking numbers pasted into Seller Hub one order at a time
  • No clear record of what is listed and at what price

With Zynk

  • Orders export from eBay into your accounts on every scheduled run
  • Stock levels import into eBay from the system that holds your inventory
  • Prices update in eBay alongside stock quantities
  • Shipping fulfilments with tracking are created in eBay automatically
  • Inventory items and offers export by SKU for checking against the ERP

How it works

How the eBay integration works

  1. Step 1: Authorise your seller account

    You sign in to eBay from the Zynk connection screen and grant access to your seller account. Zynk then connects to your accounting system, ERP or shipping platform through its own connector.

  2. Step 2: Line up SKUs and carriers

    eBay SKUs are matched to stock codes or items in your back office, and fulfilment policies are exported so each shipping carrier maps to a code that eBay accepts.

  3. Step 3: Agree order and stock rules

    We decide which orders export and when, whether they post as sales orders or invoices, and which stock figure sets eBay quantities, then test everything with sample orders.

  4. Step 4: Run and review

    Orders, stock, prices and fulfilments then move on a schedule, with any order or listing update that eBay rejects reported back to your team.

eBay and Sage 200

eBay orders import into Sage 200 as sales orders, while stock records and price bands set eBay quantities and prices, and despatch notes are returned to eBay as shipping fulfilments.

eBay and Sage 50 UK

Post eBay orders to Sage 50 as sales orders or invoices and send stock and prices back, so a small team can run eBay alongside other channels without rekeying anything.

eBay and Xero

eBay orders become Xero invoices on a schedule, so the sales ledger already reflects every marketplace sale when you start matching eBay payouts in the bank.

eBay and Shiptheory

Send eBay orders to Shiptheory for labels and carrier booking, then bring the resulting shipments back into eBay as fulfilments carrying the tracking details.

eBay integration FAQs

Will eBay orders post into Sage 50 automatically?
Yes. Zynk exports eBay orders and imports them into Sage 50 UK as sales orders or invoices. Stock levels and prices from Sage 50 can be sent back to eBay, so listings reflect what you hold and what you charge.
How does an eBay to Sage 200 integration work?
Zynk pulls orders from eBay and creates Sage 200 sales orders, then sends stock and prices from Sage 200 back to eBay. Despatches recorded in Sage 200 can be returned to eBay as shipping fulfilments, so buyers receive tracking.
Can Zynk update eBay stock levels and prices?
Yes. Zynk imports inventory quantities and prices into eBay from your ERP, accounting system or warehouse platform. Runs can be scheduled frequently during busy periods, which reduces the chance of selling an item you no longer have.
Can Zynk add tracking numbers to eBay orders?
Yes. Zynk creates shipping fulfilments against existing eBay orders, including the carrier and tracking number for each package. Fulfilment policies can be exported first to find the carrier codes eBay expects on your marketplace.
How far back can Zynk export eBay orders?
eBay only makes orders up to two years old available, so that is the limit for any historic export. Most businesses pick a go-live date and export new orders from that point onwards, leaving older sales where they already sit in the accounts.
How does Zynk connect to my eBay seller account?
You sign in to eBay from Zynk and approve access for your seller account, with a sandbox option available for testing. Zynk then works through eBay's REST selling APIs, so there is no software to install or host on your side.
Can I send eBay orders to Xero or QuickBooks?
Yes. eBay orders can be created in Xero as invoices automatically, and Zynk can send them to QuickBooks or Sage Business Cloud Accounting in the same way, so you keep whichever accounting system already holds the rest of your sales.
