Once the gross commission has been calculated on the commission worksheet, you can create a Commission Invoice for the vendor. You can also split the invoice across several lines, each on its own account (for example, salesperson commission, office commission, admin fees and marketing recovery), so your income is coded correctly in Rex and in Xero.
This article covers how to create a commission invoice, how to split it across accounts, how it syncs to Xero, and how to view existing commission invoices.
How Do I Create a Commission Invoice?
- Open the listing and switch to Finance mode using the $ button
- Go to the Commissions tab
- Under Invoices and Receipts, click the red plus (+) beside issue invoice
- Add the vendor in the invoice to field
- Check the invoice date and due date are correct
- Add a reference if needed
- The first line is filled in for you with the commission amount, described as Commission for sale of followed by the property address. If you don't have a commission structure set up, enter the amount manually. For more on this, see - Creating Commission Worksheets.
- Choose an account for the line
- To add more lines, click Add an item (see the next section)
- Click Save

Once the invoice has been created, you can apply payments against it like any other invoice.
How Do I Split a Commission Invoice Across Several Accounts?
Each line on the invoice can have its own account. To split the invoice:
- In the Create Invoice window, click Add an item for each extra line you need
- For each line, enter:
- A description (for example, "Admin Fee" or "Marketing Recovery")
- The price (inc GST)
- The account the line belongs to. Start typing to search your chart of accounts.
- To remove a line, click the X to the right of it
- Click Save
Please Note: The GST free tick box can't be changed once an account is selected on a line. This is expected. The GST is worked out from the account instead.
Please Note: Extra lines aren't filled in automatically from the commission worksheet. You'll need to add them by hand, but you only need to enter the split once.
How Does a Split Commission Invoice Sync to Xero?
If you use the Xero integration, the invoice syncs to Xero exactly as you split it. Each line lands on the Xero account its Rex account is linked to, with the GST worked out from that account.
For this to work, every account you use on the invoice must be linked to its own Xero account. For more on this, see - Xero Invoicing: Invoice Settings.
To sync the invoice, see - Xero Invoicing: Two-Way Invoice Sync.
Should I Create Commission as a Commission Invoice or a Custom Invoice?
Always create commission from the Commissions tab using issue invoice. Only commission invoices are linked to the commission worksheet. A custom invoice syncs to Xero the same way, but the worksheet will still show the commission as not invoiced.
Use a custom invoice for other fees and recoveries that aren't part of the commission. For more on this, see - Adding an Invoice.
How Do I View Existing Commission Invoices?
On the Commissions tab, click the blue eye icon next to view commission invoices. This takes you to the Invoices & Payments tab.

❓ FAQs
Can I split one commission invoice across several accounts?
Yes. Click Add an item for each line and choose a different account on each one.
Why can't I tick GST free on a line?
The GST free tick box is locked once an account is selected on the line. The GST comes from the account instead.
Will the vendor see every line?
Yes. The invoice shows each line you add, so choose descriptions you're happy for the vendor and solicitor to see.
My split invoice won't sync to Xero. What should I check?
Check that every account on the invoice is linked to its own Xero account. See - Xero Invoicing: Invoice Settings.
