To set up your Xero suppliers, go to the Suppliers page in the Xero section of the sidebar.

Xero Suppliers

This page will display a list of suppliers that have been set up in our software.

Xero Contact

For each mapped supplier, select the corresponding Xero contact from the dropdown.

Linked Xero Suppliers

If you don't want to send a supplier's invoices to Xero, you can select Disabled (Ignore). This will cause the Xero module to ignore this supplier's invoices.

Default Expense Account

To use a specific expense account as the default account for a supplier, select it from the dropdown.

This account will be used for any of this supplier's products which have not been allocated a different account.

Xero default expense accounts

If you don't want to allocate a default account to the supplier, you can select Choose per item. This will require you to select expense accounts for each product before an invoice can be sent to Xero.


To enable new invoices from a supplier to be sent to Xero as soon as they are processed, you can tick the Autosend option.

Xero autosend

Default Due Date

Invoices need a due date to be sent to Xero, but not all suppliers include a due date on their invoices.

If you have a supplier which does not include a due date, you can set a default due date by clicking the settings icon for the supplier.

This will open up the advanced settings, where you can choose how the due date should be calculated.

Once you've changed how the date should be calculated, click on Save Changes.
