If you have a Xero integration setup with TouchOffice Web, the daily sales totals should be automatically posted to Xero.
If for some reason the automatic posting fails, it is possible to manually post the sales totals to Xero.
Navigate to TILLCONFIG.NET > OFFICEWEB > XERO > Click VIEW LOGS
A list of the daily posting will now appear and you will be able to see which days have not posted.
Scroll down to the Re-importing section.
Select the appropriate site from the drop down.
Select a date range for the days that have not been posted.
Click Re-import Dates.
You may have to wait a couple of days for the postings to appear.
