E-commerce Integration for Storefronts and Marketplace Accounts

For businesses selling through Shopify, WooCommerce or marketplace seller accounts alongside their own systems, we connect the storefront to your inventory and billing so stock, orders and catalogue data stay aligned.

What Runs Separately Without This

A storefront or marketplace account shows a stock number that only it knows about, takes orders that someone has to notice and process, and lists a catalogue that has to be updated in one more place every time a price changes. The more channels a business sells through, the more of this manual repetition adds up.

What Flows Between Channels

Order Import

Orders placed on the storefront or marketplace land in your order or ERP system as they come in, with customer, item and payment details already mapped.

Stock Synchronisation

Stock levels update across every connected channel as items sell or are received, so a product does not show available on one channel after it has sold out on another.

Catalogue and Price Push

Product details, images and pricing maintained in one place get pushed out to each channel, instead of being updated separately on every storefront and marketplace listing.

Return and Refund Handling

Returns initiated on the platform are reflected in stock and accounts, so a returned item is not still counted as sold.

Marketplaces Add Their Own Rules

  • Each marketplace has its own required fields, categorisation and listing format, which the integration has to respect rather than pushing one generic catalogue everywhere.
  • Marketplace commission and fee structures differ, which affects how net revenue is calculated in your accounting system.
  • Return windows and dispute processes vary by marketplace and need to be reflected accurately.

Where Businesses Usually Feel This

  • Selling the same item on a storefront and two marketplaces with stock tracked separately on each
  • A price change that has to be made in four different places every time
  • Orders from a marketplace only discovered when someone logs in to check
FAQ

Frequently asked questions

Can you connect a storefront and multiple marketplaces at the same time?

Yes. A common setup connects Shopify or WooCommerce alongside two or three marketplace seller accounts, with stock and orders kept in sync across all of them from one backend system.

What happens if two channels sell the last unit of an item at nearly the same time?

Stock updates are pushed as close to real time as each channel's API allows, and an oversold order is flagged immediately rather than discovered at packing, so it can be corrected with the customer before dispatch.

Do we need to maintain our catalogue separately on each channel?

No, that is the point of catalogue synchronisation. Product details, images and pricing are maintained once and pushed to each connected channel in the format it requires.

Can this handle marketplace-specific fields and categories?

Yes. Each marketplace's required fields and category structure are mapped during setup, so a listing meets that marketplace's format instead of being rejected for missing information.

What drives the cost of an e-commerce integration?

The number of channels connected, whether it is one-way order import or two-way with stock and catalogue pushed out as well, and how much your product data needs cleaning up before it can be pushed reliably.

What sets the timeline for an e-commerce integration?

How quickly API access is granted on each marketplace, since some require seller verification steps outside our control, and how much catalogue data needs to be standardised before the first sync.
