Connect your Shopify store to the marketplaces you already sell on

Your own store is where your margin is best, because there is no commission in the middle. Which is exactly why it is the worst place to be unable to fill an order.

Your store is the one worth protecting most

The margin there is entirely yours

A sale in your store pays no marketplace commission. Losing it because you sold the last unit elsewhere means losing the most profitable sale you had.

Your store's customer is yours

On a marketplace the buyer belongs to the marketplace. In your store they are yours, with their email and their history. Failing them costs more than one sale.

Two storefronts, one warehouse

Shopify and each marketplace keep their own stock counter. The warehouse, however, is one. That gap is exactly where overselling is born.

What gets synced, exactly

Not just "connect and done". This is what travels between Grendry and the channel, and in which direction.

Data	Direction	When
Available stock	Grendry → channel	On any sale in any other channel
Orders	Channel → Grendry	As they come in
Prices	Grendry → channel	When you approve a change
Listings	Grendry → channel	When you create or edit a product
Shipping statuses	Both directions	On every status change

How you connect it

1

Connect the account

You authorize access from the dashboard. Nothing to install, no code to touch.

2

Match the catalogue

You pair your products with the channel's. This is the part that takes time, and we walk you through it.

3

Turn on syncing

From then on stock is deducted across every channel at once.

Questions

Yes. Grendry can be set up taking your store as the main catalogue and projecting from there to the marketplaces, or the other way round if you prefer keeping the catalogue in the dashboard.

No. The connection is authorized from the Grendry dashboard and never touches your store's template or code.

No. Sign up, connect the channel and use all of Grendry for 15 days. We only ask for a payment method if you decide to stay.

Connecting the account takes minutes. What takes time is matching the catalogue the first time, and that depends on how many SKUs you have and what shape the data is in.

Yes. The Starter plan includes two channels and the Pro and Business plans have no limit. Adding a new one does not mean redoing the work already done.
