In Polixen: Go to Accounts > Client Invoices. You will then be able to see the list of existing invoices and create new invoices by clicking on the light blue button “New Invoice” on the top right-hand side.
Once you select the invoices you wish to export, click on the green button “Xero Export Selected Invoices”.
A pop-up will appear with the option to download the CSV export file.
Once that is done, go to your Xero account and select Business > Invoices.
Click on the “Import” button. Once you are on the Imports page, go to step 3 and click on “browse” (there is no need to change anything on steps 1 and 2) and select the CSV file you just exported from Polixen on your downloads folder. Then click on “Import”.
Then click on “Complete import”
All the imported invoices will be saved as drafts. You can then review the invoices and approve them one by one or select and approve all of them at once by ticking the box next to “Number” and clicking on “approve”.
