Marketplace Integration for Australian Sellers
Every marketplace you add is a new set of listings to maintain, a new stock number to guess at, a new dispatch deadline to hit and a new settlement report nobody has time to reconcile. Two channels is manageable. Four is a full time job for somebody who was hired to do something else.
We connect Amazon, eBay, Catch, MyDeal, Kogan, TikTok Shop and specialist marketplaces to the system that actually holds your stock, whether that is an ERP, a point of sale or your own store. One stock pool with per channel buffers, orders flowing in automatically, tracking uploaded before the deadline, and fees reconciled so you can finally see which channel makes money.
Realistic ROI
What Breaks When You Add the Third Marketplace
The problems are not new at channel three, they just stop being survivable by hand.
Splitting stock between channels wastes it
The usual workaround is to allocate a fixed quantity per marketplace. It guarantees you sit on unsold stock in one channel while another shows out of stock, and it still oversells when a burst of orders arrives faster than someone updates the numbers. One pool with per channel safety buffers sells more of the same inventory and oversells less.
Marketplaces score you on operations
Late dispatch, late tracking, cancellations and defect rates all feed metrics that affect visibility and account standing. Those metrics degrade when order handling is manual, because manual means someone has to be at their desk. An integration that ingests orders and uploads tracking automatically protects the account health that everything else depends on.
Nobody can say which channel actually pays
Marketplace fees, referral percentages, fulfilment charges, promotions, chargebacks and return costs all land in settlement reports rather than on the order. Without reconciling those back to the order line, you know your gross sales per channel and almost nothing about your margin, which makes every decision about where to invest a guess.
Listings drift away from your real catalogue
A price changes in your ERP, a product is discontinued, a variant is added, a description is corrected. If each marketplace listing is maintained separately, they diverge quietly, and you find out through a customer complaint about a price you no longer honour or an order for something you no longer stock.
What Gets Connected to Each Marketplace
Six flows per channel. The first two are enough to change how the operation feels day to day.
Stock out with buffers
Available quantity flows from your ERP or point of sale to every channel from a single pool, with a safety buffer set per channel and per product velocity. Fast moving lines on a high traffic marketplace get a larger buffer than slow lines on a quiet one, rather than one blunt setting everywhere.
Orders in
Marketplace orders land in your ERP or point of sale within minutes as proper sales orders, with the channel identified, the buyer details mapped, marketplace fees noted and the marketplace order reference carried through so support and finance can trace either way.
Listings and pricing
Product data, prices and status flow from your owning system to each channel, respecting per channel pricing rules so you can price differently on a marketplace with a higher fee without maintaining a separate catalogue. Discontinued lines are ended rather than left selling.
Dispatch and tracking
Once an order is picked, dispatch confirmation and tracking are uploaded to the marketplace automatically, before the cut off that feeds your seller metrics. Carrier details flow from your freight platform so nobody is retyping a consignment number into three different portals.
Returns and cancellations
Marketplace returns and cancellations flow back into your system so stock is restored, credits are raised and the customer record reflects reality. Returns are one of the largest hidden costs in marketplace selling, and they are invisible if they never leave the marketplace portal.
Fees and settlement reconciliation
Settlement reports are matched back to orders so referral fees, fulfilment charges, promotions and chargebacks are attributed to the lines that incurred them. That is what produces a genuine margin by channel and by product, rather than a gross sales figure that flatters the wrong channel.
Manual Multichannel Versus Integrated
| Task | Traditional | With Yes AI | Notes |
|---|---|---|---|
| Stock across four channels | Fixed allocation per channel | One pool, per channel buffers | Sells more of the same inventory and oversells less than splitting it up front. |
| An order arrives at 7pm | Handled next morning | In the ERP within minutes | Dispatch clocks on marketplaces start when the order is placed, not when you open the laptop. |
| Tracking upload | Typed into each portal | Uploaded before the cut off | Late tracking is a scored metric that affects visibility and account standing. |
| A price changes | Updated on some channels | Pushed with per channel rules | Different pricing per channel without maintaining a separate catalogue for each. |
| A product is discontinued | Still selling somewhere | Listing ended automatically | Removes the orders you cannot fulfil, which are the ones that damage seller metrics. |
| A customer returns an item | Handled in the portal only | Stock and credit flow back | Returned stock re-enters the pool rather than staying invisible in a returns bay. |
| Working out channel margin | Gross sales, fees estimated | Settlement matched to orders | Referral fees, promotions and chargebacks attributed to the lines that caused them. |
| Adding a fifth marketplace | Another spreadsheet and another job | Added to the existing layer | The marginal cost of a new channel drops sharply once the pattern is built. |
How We Keep Marketplace Selling Under Control
Buffer per channel, not one number
Marketplaces differ in traffic, order burst behaviour and how harshly they treat a cancellation. A single global buffer either oversells on the busiest channel or hides stock on the quietest. We set buffers per channel and per product velocity, and review them once real order patterns are visible rather than guessing at launch.
Protect account health deliberately
Dispatch time, tracking upload time, cancellation rate and defect rate feed metrics that determine your visibility and, in bad cases, your account standing. These are operational commitments as much as technical ones, so we build alerting around approaching deadlines rather than only reporting on breaches after the fact.
Map identifiers before you launch
Your part number, the marketplace item identifier, the barcode and any channel specific code all have to line up, and they rarely do without work. Mismatched identifiers are the most common cause of an order arriving for a product your system cannot recognise, which then needs manual handling at exactly the wrong moment.
Reconcile settlements, do not estimate fees
Fees vary by category, by promotion and by fulfilment method, so an estimated percentage will be wrong in a way that hides your worst performing lines. Matching settlement reports back to order lines takes real effort to set up and is the only way to get an honest margin by channel and by product.
Handle buyer data under Australian privacy rules
Marketplace buyer information is personal information under the Privacy Act 1988 and the Australian Privacy Principles, and most marketplaces also impose their own restrictions on how buyer data may be used, particularly for marketing. We import only what is needed for fulfilment and service, and keep marketplace sourced contacts separate from your general marketing list.
Test at peak volume before peak arrives
Marketplace sales events concentrate an enormous amount of volume into short windows, and every channel API has rate limits. We test at multiples of your normal throughput, confirm queues drain rather than dropping orders, and check headroom ahead of each major sales event as part of the managed service.
How Yes AI Delivers Marketplace Integration
Channel and identifier audit first
We review each channel you sell on, map identifiers between your system and every marketplace, and quantify where the manual work and the leakage actually are. You get a prioritised plan with a fixed price, and the audit is useful whether or not we build it.
One channel at a time, highest volume first
We integrate the channel carrying the most orders first so the workload drops immediately, prove the pattern, then add the rest. Each channel gets its own buffer settings and pricing rules rather than a single template applied everywhere.
Settlement reconciliation built in
Fee and settlement matching is part of the build rather than a later project, because margin by channel is usually the reason the integration was worth doing. You end up able to answer which channel and which product actually make money, quickly.
Monitored around sales events
Same day alerting on failures, warnings before dispatch and tracking deadlines are missed, and capacity confirmed ahead of major sales events. Channel API changes are absorbed under the managed fee rather than billed as a surprise.
Our Marketplace Integration Rollout
Five steps. The first channel is normally live within four to six weeks, with the rest following faster.
Audit channels and identifiers (week 1)
Every channel you sell on, the identifiers each uses, how listings are currently maintained, where orders are handled manually, and what your fee structure looks like per channel.
Design the stock and pricing rules (week 1 to 2)
One pool with buffers set per channel and per product velocity, plus per channel pricing rules so a higher fee channel can carry a different price without a second catalogue.
Integrate the highest volume channel (week 2 to 4)
Stock out, orders in, dispatch and tracking upload, built and tested against your real data including the products whose identifiers do not match cleanly.
Add returns and settlement matching (week 4 to 6)
Returns and cancellations flowing back to restore stock and raise credits, then settlement reports matched to order lines so margin by channel becomes a report rather than a project.
Roll out remaining channels and monitor (ongoing)
Each additional marketplace follows the proven pattern with its own settings. Monitored with same day alerting, deadline warnings and capacity checks before major sales events.
