Shopify and eBay stock sync for UK sellers
Sell something on eBay and your Shopify stock drops on its own. Sell it on Shopify and eBay catches up. No spreadsheet in the middle.
How to sync Shopify and eBay stock
Connect both shops to Salync and it holds one stock count for each product. When something sells on eBay, Salync takes one off that count and pushes the new number to Shopify within seconds, and the same happens the other way round. Both shops fit inside the free plan, which covers 50 products across 2 shops with no card.
Why Shopify and eBay drift apart
Shopify and eBay each keep their own stock count and neither tells the other anything. Sell your last item on eBay and Shopify still shows it as available. Somebody buys it, and you are cancelling an order and apologising. On eBay that also costs you: cancellations count as defects, and enough of them affect how often your listings get shown.
What Shopify and eBay get from Salync
One count, both shops
Each product has a single stock number. eBay and Shopify both read from it, so they cannot disagree.
Updates as the sale happens
A sale in either shop pushes the new number to the other within seconds, not on a timer every 15 minutes.
Separate prices and titles
Your eBay title and price can differ from your Shopify one. Only the stock number is shared.
Variations handled properly
A t-shirt in three sizes is three stock counts. Selling the medium does not touch the small.

Start freeQuestions sellers ask
How do I sync Shopify and eBay inventory automatically?
Connect both shops to Salync. It holds one stock count per product and pushes changes to the other shop within seconds of a sale. There is nothing to install and no developer keys to set up.
How do I stop double selling on eBay?
Double selling happens because eBay does not know what sold on Shopify. Once both shops read from one stock count, eBay drops to the real number as soon as the Shopify sale lands, so the item cannot be bought twice.
Can I keep different prices on eBay and Shopify?
Yes. Only the stock number is shared. Titles, descriptions and prices stay whatever you set in each shop, so you can price for eBay fees separately.
Is syncing Shopify and eBay free?
Yes, within the free plan. It covers 50 products across 2 shops, and Shopify plus eBay is exactly 2 shops. No card is needed. Above 50 products, Growth is £49 a month.
What happens to my eBay variation listings?
Each variation is treated as its own product with its own stock count. Selling one size does not change the others.
