E-commerce Integration: One Operation Across Every Channel
E-commerce integration unifies every channel you sell on — marketplaces, your own website and social commerce — into a single stock, order and profitability operation. It differs from marketplace integration in scope: it brings your own store and back office into the same flow, not just marketplaces.
How does e-commerce integration differ from marketplace integration?
Marketplace integration is narrow in scope: it connects marketplaces to each other. E-commerce integration adds two more layers on top — your own storefront and the back office (accounting, e-invoicing, ERP, carriers).
The difference shows up in practice: for a seller using marketplace integration only, stock on their own site stays independent and the two channels never see each other. With e-commerce integration, all channels share one stock pool. Wherever an order comes from, it lands in the same pick list, enters the same shipping flow and rolls up into the same profitability report.
What goes wrong most often in multichannel selling?
Four problems recur. Split stock: reserving separate stock per channel makes a product look "sold out" in one channel while units sit in the warehouse. Price inconsistency: price gaps between channels produce customer complaints and marketplace warnings. Scattered orders: orders noticed at different times across panels stretch shipping time. Profitability blindness: because commission, shipping and return costs differ per channel, you cannot tell which channel actually earns money without per-channel profit.
All four share one root: data is spread across channels and never joins up. That is integration's real job — not adding features, but reducing scattered data to one truth.
How do you measure profitability per channel?
Per-channel profit is channel revenue minus the costs specific to that channel. On marketplaces those are commission, shipping, platform service fee and return handling cost. On your own site, payment processing fees, shipping and advertising come in.
Measurement accuracy depends on the source of the commission data. An estimated rate from a category table is fine for pre-sale pricing; realised profit reports should use the actual commission amount returned by the order API. On low-margin products, the gap between the two is the gap between profit and loss.
Which channel should be integrated first?
The order is decided by error cost, not revenue. Connect the channel that produces the most stock errors first. In practice that is the marketplace with the highest order volume: an oversell there causes both a cancellation and a rating loss, and its impact exceeds the other channels.
Second comes the channel that shares the same products, because stock collision is only solved once both channels are connected. With a single channel connected, the return on a shared stock pool is limited. Your own website usually comes third: it needs technical configuration and produces fewer urgent errors than marketplaces.
Accounting and e-invoicing integration can be left until last. It does not create operational errors and can be corrected in bulk at period end, whereas a stock error hits sales and store rating immediately.
How long does an integration project take?
Connecting a single marketplace takes minutes: enter the API key and start the first sync. What extends the project is not the connection but catalog preparation.
Three things determine the timeline: product count, barcode/SKU consistency, and how complex the variant structure is. In a catalog with tidy barcodes and clear variants, post-sync verification takes a few hours. In a catalog carried on missing or hand-entered codes, the real work is cleanup and it can take days.
So the realistic plan is: set up the connection in a day, enable automation only for verified products in the first week, then widen coverage as catalog cleanup progresses. Turning automation on across the whole catalog on day one writes mismatches to the marketplace just as fast.
What changes when you expand internationally?
Selling into foreign marketplaces introduces three new variables: currency, tax and customs, and delivery time. Pricing can no longer be done in one currency; the profit calculation has to carry conversion and currency movement.
On the catalog side, language and category mapping get harder: the same product has to fit a different category tree with different required attributes in each country. So the critical capability in global integration is not "supporting more marketplaces" but carrying multi-currency and per-country catalog rules.
Frequently asked questions
Can I also connect my own e-commerce site?
Yes, if your platform supports an API or webhooks. Unlike a marketplace connection this needs some technical configuration; tell us which platform you use and we can check compatibility.
Are accounting and e-invoicing included?
Invoice integration is a separate module and varies by plan. Check the current plan comparison to confirm scope.
How is stock allocated across channels?
Through a shared stock pool: physical stock sits in one pool, is distributed to channels by rule, and any sale deducts from the pool. Channels therefore cannot sell the same unit unaware of each other.
