Every in-store sale on Eposnow instantly updates your Wix online shop. No manual stock edits, no double-sold items, no frustrated customers who ordered something you can no longer fulfil.
StockClerk designates Eposnow as your single source of truth. Every sale — whether in-store, on Wix, or via a delivery app — flows through StockClerk and keeps all channels in lockstep. Your Wix product inventory is always accurate, always current.
StockClerk isn't a simple webhook — it's a coordinated system of four agents that catch edge cases, fix drift, and alert you to anything genuinely important.
Monitors your Eposnow POS and Wix store simultaneously. Any stock movement — sale, return, or manual adjustment — is captured instantly.
Receives the change signal from Watcher and pushes the correct stock level to your Wix product inventory via the Wix API. Completes in under 5 seconds.
Runs an independent full-catalogue audit every 15 minutes. Compares Eposnow and Wix inventory item by item. Corrects any drift automatically — even if the original event was missed.
Filters routine sync activity and only pings you when something needs human attention — like a low stock warning or a connection issue with your Wix store.
Three simple steps to get your Eposnow and Wix inventory fully connected and automatically synced.
Paste your Eposnow API key from your Back Office settings. StockClerk imports your full product catalogue automatically. For most retailers, this takes under two minutes.
Connect your Wix store using Wix's OAuth flow — you'll be redirected to Wix, authorise StockClerk, and return. No API keys to copy, no webhooks to configure manually.
StockClerk aligns your Wix inventory to match Eposnow. Any discrepancies from before you connected are resolved. From this point, every sale keeps both channels current automatically.
Eposnow and Wix are both excellent platforms built for very different purposes. Eposnow is a powerful point-of-sale system designed for physical retail — managing transactions, receipts, and in-store inventory. Wix is a website and eCommerce platform designed for building online shops. Neither company has an incentive to build a deep, real-time inventory bridge to the other.
The result is that retailers running both face a structural gap. Every sale in one system needs to be manually reflected in the other. For shops processing hundreds of transactions a week, this manual overhead is substantial — and the margin for error is constant.
StockClerk fills this gap using the APIs that both platforms expose, managing the sync logic reliably and automatically.
Even the best real-time sync can occasionally miss an event — perhaps due to a brief API timeout, a network blip, or a manual change made directly inside one of the platforms. This is why the Guardian agent exists as a separate, independent layer.
Rather than relying solely on event-driven updates, Guardian performs a full catalogue comparison every 15 minutes. It queries your Eposnow stock levels directly, queries your Wix product inventory, and compares every item. If the numbers don't match, it corrects them immediately, silently, without requiring any action from you.
This dual approach — event-driven sync plus periodic reconciliation — means that even in edge cases, the maximum time your stock is out of sync is 15 minutes. In practice, for the vast majority of updates, it's under 5 seconds.
One of the more complex scenarios StockClerk handles is when an online Wix order and an in-store Eposnow sale occur within seconds of each other on the same product. StockClerk uses a transaction queue to process updates in the correct order, preventing race conditions from resulting in a negative stock count or an oversold product. The final inventory figure accurately reflects both transactions.
If you have products listed on Wix that don't exist in Eposnow — perhaps digital downloads or online-only items — StockClerk respects that distinction and doesn't interfere with them. Only products that exist in both systems are subject to sync. You can also mark specific Eposnow products as excluded from Wix sync if needed.
StockClerk is particularly well suited to independent retailers who want a physical store presence alongside an online shop without the operational overhead of managing stock in two separate systems. Gift shops, fashion boutiques, bookshops, homeware stores, and artisan goods retailers are all examples of shops that would benefit from using StockClerk.
We had a popup on our website for weeks telling customers to phone the shop because our online stock was wrong. Within 15 minutes of connecting StockClerk, our Eposnow and Wix inventory was perfectly in sync. No more overselling, no more disappointed customers.
