How to sync Loyverse inventory with your Wix store

By Kayabyte

Loyverse POS and Wix Stores don’t share stock on their own, so a sale at your Loyverse till doesn’t lower your online stock, and an online order doesn’t lower the count in Loyverse. To keep one stock count you either update both sides by hand, move counts with spreadsheet exports, or use an app that syncs Loyverse and Wix as sales happen. This guide covers all three, and what to set up in Loyverse first so the sync doesn’t oversell.

What Loyverse and Wix can do on their own

• Loyverse has no online store of its own. It is a point of sale with a Back Office for items and stock. Selling online goes through an integration from the Loyverse marketplace or through the Loyverse API.
• Wix has no Loyverse connection. Wix Stores keeps its own stock per product and variant. Wix’s own point of sale (Wix POS) shares stock with Wix Stores, but that means replacing Loyverse at the till.
• Integrations are free on Loyverse. Loyverse’s pricing page lists integrations among the free tools, so connecting an app needs no paid Loyverse add-on. The app itself may cost money.

If you want to keep Loyverse at the till and Wix online, read on.

Option 1: update both sides by hand

Fine for a handful of one-off items. After each till sale, lower the product’s stock in Wix dashboard > Store Products > Inventory. After each online order, lower the count for the item in Loyverse Back Office > Items > Item list.

It breaks down as soon as you sell the same item in both places on a busy day: until you catch up, the web shop can sell stock you no longer have.

Option 2: export and import spreadsheets

Loyverse Back Office can export your item list as a CSV file, including the In stock column for each store, and Wix Stores can import products from a CSV file.

Things to know:

• The two files have different columns, so you rework the sheet each time.
• An import overwrites counts. Any sale made between the export and the import is lost, on either side.
• It’s good for the first upload of products, not for day-to-day stock.

Option 3: an app that syncs as sales happen

A sync app listens for stock changes on both sides and usually copies them across within seconds. When you compare apps, check these points, because they decide whether you’ll still oversell:

1. Both directions. An online order must lower the Loyverse count, not only the other way round.
2. Sales on both sides at once. If a customer buys online while you sell the same item at the till, both sales must count. Loyverse accepts only a new total for a stock count, so a careful app reads the current Loyverse count right before it writes. That leaves only a split second in which a till sale of the same item can be missed; ask how an app handles it.
3. A safety check. Notifications are occasionally late or missed. A regular check that compares both sides catches what slipped through.
4. Matching by SKU. Products should link automatically when the SKU is the same, and duplicate SKUs should be flagged, not guessed.
5. Stores. If you run several Loyverse stores, your online shop should follow the stock of one chosen store.
6. Where you manage it. Some connectors run on their own website with their own login; others run inside your Wix dashboard.
7. Busy hours. In our tests on 13 November 2026, Loyverse’s API accepted 30 writes an hour per account, shared by every app connected to it. Ask what an app does when a busy hour reaches that limit: it should queue and group changes, not drop them.

Before you connect anything

• Switch on Track stock in Loyverse. In Back Office > Items > Item list, open the item and switch on Track stock in the Inventory section. Loyverse only keeps a count for items with tracking on, and a sync can only work with those.
• Give every item the same SKU in both places. Variants too: “TEE-RED-M” in Loyverse and “TEE-RED-M” in Wix. Loyverse SKUs are unique per account and up to 40 characters. Case and extra spaces usually don’t matter to a sync app, but spelling does.
• Decide which side has the right counts today. Usually that’s Loyverse, because you count stock in the shop. The first sync copies counts from that side.
• Composite items and items sold by weight. A Loyverse composite item (a bundle made of other items) takes its stock from its components, and items sold by weight have fractional counts. Online stores count whole units, so most syncs leave these out.
• Several stores. Loyverse keeps a count per store. Pick the store that holds your online stock.

Our app: Inventory Sync for Loyverse

We make Inventory Sync for Loyverse, a Wix app built around the checklist above.

• Two-way stock sync, usually within seconds. Wix orders lower the Loyverse count, and till sales lower the Wix stock. In a very busy hour, changes going to Loyverse are queued and grouped to stay within Loyverse’s 30 writes an hour.
• Loyverse counts are read right before every write, and a safety check every 15 minutes compares both sides.
• Automatic linking by SKU, with duplicates listed for you to sort out, and an activity log of every change.
• One chosen Loyverse store; works with the free Loyverse plan and any currency.
• Pro adds price sync in the direction you choose, imports Loyverse items as Wix products, and creates Wix products in Loyverse.

The Free plan syncs up to 25 items. Pro is $14.99 a month, or $12.49 a month billed yearly, with a 14-day free trial. Get it on the Wix App Market. Inventory Sync for Loyverse works with Loyverse and is not affiliated with or endorsed by Loyverse.

FAQ

Does Loyverse integrate with Wix? Not out of the box. Neither Loyverse nor Wix has a built-in link between Loyverse POS and Wix Stores, so you need a connector: an app inside Wix, a connector service listed on the Loyverse marketplace, or an automation tool.

Can I use Loyverse at the till and Wix for my online store? Yes. Many small shops do. The risk is overselling, which a two-way stock sync greatly reduces.

What happens if a customer buys online while I sell the same item at the till? With a two-way sync, both sales are taken off the other side (with Loyverse, a till sale in the same split second as an app’s write can still be missed, so count stock now and then). With manual updates or spreadsheet imports, one of them can be lost until you recount.

Do I need a paid Loyverse plan to sync stock? No. Stock tracking is part of Loyverse’s free plan, and Loyverse lists integrations as free. The Advanced Inventory add-on (purchase orders, transfers, counts) is not needed for a sync.

Do I need to re-enter my products in Wix? No. Items with matching SKUs link automatically. With a sync app that imports items, products that exist only in Loyverse can be created in Wix, and the other way round.
