WooCommerce Xero Inventory Sync Guide: Stock Updates That Stop Overselling
==========================================================================

**Last updated:** 22 July 2026
**Reviewed by:** the Wbsync team

**TL;DR:** Useful inventory sync for most stores is **Xero → WooCommerce** on a schedule — not magic real-time product cloning. With Wbsync, quantities update about **every hour** on **paid plans**, matching SKU/item codes so offline sales in Xero can stop the website overselling.

### Do this in 5 steps

1. **Connect** WooCommerce and Xero in Wbsync ([register](https://app.wbsync.com/register)) and create a **Sync**.
2. **Confirm a plan that includes inventory** — free order sync does not include stock updates ([pricing](/pricing)).
3. **Align SKUs** in WooCommerce and Xero for products you care about (exact codes).
4. **Enable inventory quantity sync** on the Sync (orders can stay off if you only want stock).
5. **Spot-check** high-velocity SKUs after the next hourly pass; treat Xero as the stock master for offline sales.

Large catalogues can take longer on a full pass. Pairings: [Connections](/connections).

### Why stock drifts

Offline sales hit Xero only; web sales hit Woo only; SKUs differ (`ABC-1` vs `ABC1`); two people edit stock in both systems; tools push invoices but never quantities. Sync only helps if **one master** owns stock — for this flow, Xero quantities for matched items.

### Operate cleanly

- Record offline sales so they land in Xero.
- Don't hand-fight website stock if the next hourly pass will overwrite it.
- Use buffer stock if you sell faster than hourly updates protect you.
- Run orders + inventory together when you want sales in the books *and* stock on the site — [automate orders guide](/how-to/woocommerce-xero/woocommerce-xero-automate-orders-to-invoices).

FAQ
---

### Is inventory sync real-time?

No. About every hour on paid plans.

### Which system owns stock?

With Wbsync inventory sync, treat **Xero quantities** as the source that updates matched store SKUs.

### Full product sync?

No — quantities for matching codes, not a catalogue content pipe.

### Will this stop all overselling?

It reduces overselling when codes match and offline sales hit Xero. It cannot beat sales faster than the update cycle.

### Inventory without order sync?

Yes. Enable features independently per Sync.

### Free plan?

Inventory is not included — see [pricing](/pricing).

Where Wbsync fits
-----------------

Orders into Xero on a schedule, inventory quantities back to the store on paid plans, logs, and Adelaide business-hours support. Honest limits beat "real-time" claims that don't match operations.
