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 — Invoice Sync for Xero gives that time back.
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.
<h2>What gets synced to Xero</h2>
Every invoice created by the plugin includes:
<ul>
<li>Customer contact — matched by email address to an existing Xero contact, or created automatically. No duplicate contacts.</li>
<li>Product line items — every item in the order, with quantities, unit prices, and your configured account code</li>
<li>Shipping — as its own line item, with a separate tax type if needed</li>
<li>Fees — payment surcharges, handling fees, and any other WooCommerce fee items</li>
<li>Tax amounts — passed from WooCommerce to Xero to keep invoice totals aligned with the order.</li>
<li>Invoice date — set to the original WooCommerce order date, not today’s date</li>
<li>Currency — the WooCommerce order currency is passed to Xero, supporting multi-currency organisations</li>
<li>Payment record — 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>Automatic sync — invoices are created when orders reach Processing or Completed status. No action needed.</li>
<li>Immediate sync — optionally create invoices the moment an order is placed, before payment is confirmed. Useful for BACS, bank transfer, and offline payment methods.</li>
<li>Manual send — 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>Failed sync safety — if a sync fails for any reason, the error is recorded as an order note. The customer’s checkout is never interrupted.</li>
<li>Contact updates — 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>
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.
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.
<h2>Getting started</h2>
Setup takes around 10 minutes:
<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 WooCommerce → Settings → Xero Invoice Sync, enter your credentials, and click Connect to Xero.</li>
<li>On the Mapping tab, select your Sales Account Code and Tax Type.</li>
<li>Save. Done.</li>
</ol>

Set Custom Order Number Formats in WooCommerce
Custom Order Numbers for WooCommerce replaces the default WordPress Post IDs with structured and meaningful order numbers. You can define order sequences that match your business needs using letters, numbers, dates, or custom fields. Create formats like WT195, ORD1001, INV2025, or STORE0501 with just a few clicks.
The extension allows you to generate sequential order numbers, apply custom sequences, or reset numbers automatically. You can update existing orders or apply changes only to new ones, giving you complete control over WooCommerce custom order numbers and ensuring clear order tracking across your store.

 Customize Your Order Number Sequence in WooCommerce
Easily manage your order numbers sequence in WooCommerce by creating a clear sequential order that reflects your store workflow. You can add custom prefixes or suffixes, such as WT or EU, to identify departments or regions. 
You can also set a custom starting number, for example 1000 instead of 1, which is helpful when migrating from another platform or extension. 
These customization options make it simple to define order numbers that follow a logical sequence while also meeting internal or legal requirements. Standardizing your order numbering using the extension helps improve clarity, ensure consistency, and simplify order tracking.

Choose Custom Increment for WooCommerce Order Numbers
Not all stores want consecutive order numbers increasing by 1. With this extension, you can define a custom increment value for your sequential order numbers. Whether you want to increase order numbers by 5s, 10s, or any other interval, the extension gives you complete control.
Example: 
Instead of #1001, #1002, #1003, you can generate #1005, #1010, #1015, and so on.

Reset WooCommerce Order Numbers Automatically
Choose how often your WooCommerce order numbers reset, whether daily, monthly, or yearly. This helps stores organize orders by time periods, such as quarterly reports or financial cycles, and also keeps order numbers shorter and easier to manage.

Use a Separate Order Number Sequence for Free Orders
This WooCommerce sequential order numbers extension lets you maintain a separate order number sequence for free orders, giving you better clarity in tracking and reporting. By separating paid and free orders, you simplify accounting, improve business insights, and avoid confusion when reviewing sales performance.
 
Example:
<ul>
<li>Paid Orders: ORD-1001, ORD-1002</li>
<li>Free Orders: FREE-0001, FREE-0002</li>
</ul>
