This integration does not enable to push wallet loads from Spendesk to Xero. You have to add them manually on Xero.
Process to manually export wallet loads
In Xero, go to Accounting > Bank accounts and click on the bank account that you used to load Spendesk. Then click on the 'Reconcile' tab and link the wire transfer to your Spendesk bank account.
In Spendesk, download your account statement in .csv format under Settings > Company Wallet > Account statements.
Keep only the credit lines on the file (else, you will also create the debit values, so you will have duplicates).
In Xero, upload your Spendesk bank account under Bank accounts > Bank statements by clicking on Manage Account then Import a Statement.
Error message for incorrect data
If you have an error message saying that data is incorrect when uploading your account statement into Xero, please read the following:
The problem is that Spendesk exports CSV with ';' separators, but Xero expects ',' separators.
To be able to upload the file to Xero, you need to:
either replace the ';' by ',' in the raw file;
or open the file on Excel (or equivalent) and export it as a CSV with ',' as lines separators.
