<p>Every time a customer places an order in your WooCommerce store, someone has to get it into Xero. If that someone is you — copying line items, looking up contacts, checking tax amounts — <strong>Invoice Sync for Xero</strong> gives that time back.</p>
<p>The plugin connects your store directly to Xero over a secure OAuth2 connection. Orders become invoices automatically, with the contact matched by email, tax amounts passed from WooCommerce, complete line items, and the original order date used as the invoice date.</p>
<h2>What gets synced to Xero</h2>
<p>Every invoice created by the plugin includes:</p>
<ul>
<li><strong>Customer contact</strong> — matched by email address to an existing Xero contact, or created automatically. No duplicate contacts.</li>
<li><strong>Product line items</strong> — every item in the order, with quantities, unit prices, and your configured account code</li>
<li><strong>Shipping</strong> — as its own line item, with a separate tax type if needed</li>
<li><strong>Fees</strong> — payment surcharges, handling fees, and any other WooCommerce fee items</li>
<li><strong>Tax amounts</strong> — passed from WooCommerce to Xero to keep invoice totals aligned with the order.</li>
<li><strong>Invoice date</strong> — set to the original WooCommerce order date, not today’s date</li>
<li><strong>Currency</strong> — the WooCommerce order currency is passed to Xero, supporting multi-currency organisations</li>
<li><strong>Payment record</strong> — optionally marks the Xero invoice as paid when the WooCommerce order is paid, against a bank or clearing account of your choice</li>
</ul>
<h2>Built for how real stores operate</h2>
<ul>
<li><strong>Automatic sync</strong> — invoices are created when orders reach Processing or Completed status. No action needed.</li>
<li><strong>Immediate sync</strong> — optionally create invoices the moment an order is placed, before payment is confirmed. Useful for BACS, bank transfer, and offline payment methods.</li>
<li><strong>Manual send</strong> — push any order to Xero at any time using the Order Actions dropdown on the order edit screen. Works even with automatic sync disabled, and is perfect for backfilling older orders.</li>
<li><strong>Failed sync safety</strong> — if a sync fails for any reason, the error is recorded as an order note. The customer’s checkout is never interrupted.</li>
<li><strong>Contact updates</strong> — keep customer phone numbers and addresses in Xero current automatically on each order, or disable this to preserve manually managed contact data.</li>
</ul>
<h2>Tax that actually matches</h2>
<p>Getting tax right between WooCommerce and Xero is notoriously difficult with other plugins. Invoice Sync takes a different approach: it reads the tax amounts WooCommerce calculated for each line item and passes those figures directly to Xero. This is designed to keep totals aligned and reduce “Includes adjustments to tax” warnings when WooCommerce tax settings are configured correctly.</p>
<p>The Xero tax type you configure (e.g. GST on Income, Tax on Sales) tells Xero how to categorise the tax for your P&L and tax return — it does not affect the invoice total.</p>
<h2>Getting started</h2>
<p>Setup takes around 10 minutes:</p>
<ol>
<li>Create a free OAuth2 app at <a href="https://developer.xero.com/app/manage">developer.xero.com</a> to get your Client ID and Client Secret.</li>
<li>Go to <strong>WooCommerce → Settings → Xero Invoice Sync</strong>, enter your credentials, and click <strong>Connect to Xero</strong>.</li>
<li>On the <strong>Mapping</strong> tab, select your Sales Account Code and Tax Type.</li>
<li>Save. Done.</li>
</ol>
