We've improved our "Client Import" feature, that enable to make update to existing client/s in LodgeiT.
To use this new feature, simply check the box next to "Update existing clients".
This associated with any of the client import sources (Xero Tax, Sofware Assistant, HandiTax and CSV).
Additionally, we've extended the search functionality for existing clients. Now they will be searched by Id or tax details ( ABN, TFN, ACN), or reference number.
