This customisation is designed to allow ImportPlus to automatically allocate Sales Payments on Account (and Sales Credit Notes) against Sales Invoices where the reference number of the invoice matches the reference number of the payment.

1. Run ImportPlus Driver
2. Select 'Tools' (group)
3. Run 'Collect and Install Customiser' (operation)
4. When asked for an ID provide 0004
5. Then click the 'Proceed' button.

Once collection is complete, the operation will be available in the Customisers group.
