Sell in-store, on Etsy, or at a market too? The moment two channels both think an item is available, you're one oversold order away from an angry customer and a refund you didn't budget for.
Stock updates automatically, so you're never the one writing "sorry, that's actually out of stock."
An order for stock you don't have is a refund you didn't plan for. Sync closes that gap before it opens.
Hold back 1–2 units on your highest-risk items with a safety buffer, so the sync gap can't touch them.
Enter your store domain below. Takes under a minute, no card needed.
Your dashboard shows current stock and flags anything that looks off before you sync it.
One click holds back a unit or two on anything you can't afford to oversell.
Honestly, no — and we don't think any tool truly is. Even fast sync leaves a small window between a sale happening and every channel catching up. Instead of chasing an impossible "instant," Inventory Sync lets you hold back a small safety buffer on your riskiest items, so that window can't cause an oversell in the first place.
Just what's needed to read your products and locations, and update inventory levels. Nothing related to customer data, orders, or payments is requested or touched.
No — you can connect and start your 14-day free trial even while your own Shopify store is still on its own trial. Nothing is charged until you're both out of trial and choose to subscribe.
Billing runs entirely through Shopify's own subscription system — the same place your Shopify plan itself is billed. There's no separate checkout or third-party payment processor involved.
Nothing writes silently. Before any sync applies, you see exactly what's about to change and confirm it. If a safety buffer would take a product fully off-sale, you get a warning first instead of it happening automatically.
Inventory Sync connects to your Shopify store directly. It's built specifically for sellers who ALSO sell in-store, on Etsy, or at markets — the core problem it solves is exactly that gap between Shopify and everywhere else you sell.
Connect your store and see your real stock picture in under a minute.
One oversold order costs you a refund, shipping you don't get back, and often the customer for good. $29/month is cheaper than a single one of those.
